The Great Beyond

New images of the Great Beyond’s volcano of the year (to date): Sarychev Peak in the Russian Kuril Islands.

Although not quite on a par with the awesome shot from last week (see: Picture post: BOOM!) this double act show the impact of an eruption like the one that Sarychev experienced beginning 12 June. The ‘before’, top, was taken 26 May while the ‘after’, below, is from 30 June.

Acquired by the ASTER instrument that graced this blog yesterday, these false-colour images show vegetation as red, water as dark blue, and bare rock as brown / gray. The white patches are either ice or clouds.

NASA notes:

The most striking difference between these two images is the cap of new volcanic rock coating the northwestern half of the island in June 2009. While vegetation on the rest of the island appears lush, little or no vegetation remains on the northwestern end. A close look at the top image also reveals that the recent volcanic activity appears to have expanded the island’s coastline on the northwestern end.

The most hotly awaited science song of they year, nay, the decade, has arrived. Buzz Aldrin has released his rap!

Recently the New York Times reported that Aldrin had been in a rap session with Snoop Dogg. It transpires that Aldrin and Mr Dogg do not actually rap together, rather the latter has produced the former’s song.

You can see the full video on the Funny or Die website.

While this is unlikely to go down as a classic, the making of video that accompanies it has some choice moments. “I have only two passions, space exploration and hip hop,” declares Buzz ‘Doc Rendezvous’ Aldrin.

Perhaps the best part though is where Aldrin discusses Gill Scott-Heron’s seminal ‘Whitey On the Moon’, a tirade against spending money on spaceflight when there is so much poverty on Earth.

“Me and Gill are cool now,” says Doc Rendezvous. “I explained to him we came in peace for all mankind and he backed off.”

The new Top 500 supercomputer list is out, and it looks remarkably like the previous one, in that it charts a continuing exponential growth in the aggregate power of the worlds top computers. Awesome technological achievement – but no great surprise. As The Register puts it in a headline “World Yawns at Petaflops”.

The yawning is helped by the fact that the number one and number two computers this time round are the same as they were last time round: the US Department of Energy’s Roadrunner, at Los Alamos, and its Jaguar, at Oak Ridge.

But if you want to get geeky on the topic there are some possibly interesting details and trends to see in the data that the Top 500 lists creators make available in a variety of helpful formats.

UPDATE: Some are now questioning the maths behind this analysis. See: John Graham-Cumming, Times.

It is widely acknowledged that humans are very bad at making up random numbers. If we weren’t we wouldn’t have invested so much time in developing random number generators.

Now some work by political scientists Bernd Berber and Alexandra Scacco, of Columbia University, suggests that fact hasn’t reached certain key individuals in Iran. As the country struggles with the violent aftermath of its recent hotly contested election, Berber and Scacco say the results of that election seem highly suspicious.

They used the results published by the Ministry of the Interior and examined the last two digits of the votes reported for the four main candidates.

“The numbers look suspicious,” they report in the Washington Post.

Carl Linnaeus, the Swedish naturalist behind the first widely-used taxonomy of plants and animals, faced a problem modern biologists confront all the time: too much data. His solution was simple, says science historian Staffan Mueller-Wille: Linnaeus invented index cards.

“Although a seemingly mundane and simple innovation, Linnaeus’ use of index cards marks a major shift in how eighteenth-century naturalists thought about the order of nature,” says Mueller-Wille (press release).

He says Linnaeus first sorted his ideas onto individual sheets of paper so they could be shuffled, and years later shrank the size of his notepaper to make them easier to handle.

Mueller-Wille, of the University of Exeter, will be chatting about his ongoing research into how Linnaeus invented his famous taxonomy on 4 July at an outreach event organized by the British Society for the History of Science in Leicester, UK.

Mueller-Wille and colleague Sara Scharf published a working paper [pdf]on the topic with the London School of Economics in 2007.

It is hard to avoid using the phrase “scientists have discovered ….” But here we go again: Scientists have discovered a way to make concrete last for 16,000 years.

This is not, as on first inspection it might seem, the environmental nightmare it sounds like. What Matthieu Vandamme from the Université Paris-Est and Franz-Josef Ulm from the Massachusetts Institute of Technology have done is work out why concrete creeps, or gradually deforms over time.

The answer is published in PNAS this week and appears to be the way that calcium-silicate-hydrate crystals rearrange themselves at the nanoscale.

This process can’t be stopped, the researchers say, but can be slowed. Slowed so that concrete will last 16,000 years, says GreentechMedia.

So what is creep? Well, according to Ulm, it’s like chewing gum. Gum will stretch and compress if a constant force is applied, Science News tells us, and this, says Ulm is what concrete does, but at a much larger scale.

The hope for creep-free concrete in future is now in the hands of nanoengineers who with the help of this latest research might be able to come up with an additive that slows the creep right down.

News of 'the world's first scientific experiment on Twitter' has received some media pickup today. The trial starts tomorrow, conducted by psychologist Richard Wiseman together with New Scientist.

Wiseman, who works at the University of Hertfordshire, UK, says the study will examine the psychic ability of 'remote viewing' - the idea that one can see an object without being shown or told what it is. He'll tweet from a location, then offer five photo options; tweeters have to guess which of the five he is actually in. The trial will be repeated four times using different locations (3pm, Tuesday to Friday this week).

Although rigorous scientific experiments have been conducted into remote viewing before (with no evidence found for the ability), this isn't one of them. The choice of Twitter pretty much guarantees that, as Wiseman readily concedes in conversation, though not in his quoted press comments.

Here’s a story to bring music to your ears. Computer scientists in the UK have allowed instrument makers to build a horn specified by Bach to be played in a particular ditty of his, but an instrument that has since never been heard of.

The work, supported by the UK’s engineering and physical sciences research council (EPSRC) has allowed the lituus to be made. This is a long, thin horn that Bach specified for one particular cantata, ‘O Jesu Christ, meins lebens licht’ (BWV 118)’ written in 1736-37. Swiss conservatoire, Schola Cantorum Basiliensis, contacted Murray Campbell from the acoustics & fluids group, in the University of Edinburgh’s school of physics and astronomy with the hope that he could remodel the lost instrument

“It’s called ‘Bach’s forgotten horn’ because Bach specified this in this particular cantata but nobody knows what he meant. There were no instruments known to have been around in Leipzig in Bach’s time which were called lituuses, no lituus player appear on any rolls of musicians, no one knows what exactly he meant,” says Campbell.

Campbell’s PhD student Alistair Braden did the modelling based on fragments of information from the Swiss musicians about what the lituus might have sounded like, or looked like. Braden used optimisation software that he developed to get to the final design, a blueprint to give to the instrument makers.

The result was a long, wooden horn that is apparently difficult to play.

The BBC has a story with an audio clip of the whole piece, lituus and all.

The Google search engine offers a predictive function, where it will suggest things you might be looking for in advance of you completing your query. As these are at least partially based on what other people have been searching for, can they provide some insights into the way science is perceived on the interwebs? The Great Beyond investigates.

Initial results are not promising. There seems to be widespread skepticism of evolution for a start. This page is from the US version of Google:

Last week Nature’s Lucas Laursen exposed a Facebook network of stem cell scientists that was not all it seemed. Over 100 scientists, policy-makers and journalists have had their identities purloined to create a fake network of people linked to stem cell science.

One of the few real people in the network was Forbes science editor Matthew Herper, who accepted a seemingly authentic friend request from a fake version of Washington Post reporter Rick Weiss. Now Herper has written a piece for Forbes entitled, ‘I Was Impersonated On Facebook’.

“My trip from Facebook to fakebook began in February when I got a friend request from Rick Weiss, the former Washington Post science writer. I'd admired Weiss' work for years and was thrilled to speak on a panel with him in Madison, Wis.; I accepted the request immediately,” he says.

Following hot on the heels of the theft of computer data on America’s most advanced fighter plane, President Obama’s cybersecurity advisor has called for more to be done in safeguarding information.

Melissa Hathaway, acting senior director for cyberspace, is leading a review into the issue of cybersecurity which the New York Times says “is simply the opening round in what may become a bruising political battle over how much control should be exercised and over which agencies of the government will take command of computer security”.

The review will likely be made public at the end of the month but Hathaway, speaking at the RSA 2009 conference in San Francisco, said cybersecurity was “one of the most serious challenges of the 21st Century”. She called for public and private organisations to come together with individuals to secure the internet (BBC).

“A few hours south of here, there are creative Hollywood writers and actors who have imagined and produced stories that capture the essence of the problem, including: Matthew Broderick in War Games, Robert Redford in Sneakers, Sandra Bullock in The Net, and Bruce Willis in Live Free and Die Hard. These and other movies present the types of issues that we should care about and solve together,” Hathaway told the conference (remarks from The Atlantic).

Back in the day, Chinese scientists like Wen Ho Lee had to come to the US to be accused of stealing secrets. More recently, a US researcher is awaiting sentencing in America for sharing technology with his Chinese student. But the world is changing fast, and today's Wall Street Journal has an incredible story of how the Chinese are now being accused of stealing US technology from the comfort of home.

The Journal article details how hackers have stolen terabytes (that's TERABYTES) of data on the F-35 Joint Strike Fighter, a US$300 billion project that is the Pentagon's costliest development programme ever. The attackers infiltrated contractor computers during 2007 and 2008 and siphoned off sensitive details about the design and electronics systems of the aircraft. The most sensitive data were kept on a secure Pentagon server and appear to be safe, but the hackers made off with mounds other stuff. It's not even clear what they managed to steal: the infiltrators encrypted the data that they siphoned off, leaving Air Force forensic teams stumped.

Like many cyber attacks, the espionage appeared to originate in China. Of course nobody knows for sure that Chinese nationals were behind the attacks, but that hasn't stopped speculation that, once again, the Chinese have gotten hold of the US's most sensitive secrets. The Chinese Embassy in Washington called those allegations "a product of the Cold War mentality" and said that they were meant to "fan up China threat sensations."

Lockheed Martin Chief Financial Officer Bruce Tanner says, via the Washington Post, "To our knowledge there's never been any classified information breach." He went on to say, "Like the government, these attacks on our systems are continuous, and we do have stringent measures in place to both detect and stop these attacks."

UPDATE – Current Nature editor Philip Campbell’s tribute, John Maddox 1925–2009, is now on our website:

It was with great sadness that I and my colleagues at Nature learned of the death on Sunday of Sir John Maddox — or 'JM', as his colleagues always referred to him.

There was puzzlement, too. Yes, John had been looking frail recently, but, well, this was JM — the perpetually restless, irresistible, unstoppable force. The editor who conducted some gatherings with 'shock and awe' as some recall. The 'man with a whim of iron' as others used to call him. And the man who survived countless cigarettes and glasses of red wine, many consumed late into the night as he wrote the week's Editorials at the last possible moment.

As Walter Gratzer, of King’s College, London, wrote recently, “John Maddox brought an old-fashioned Nature into the modern age from the mid-1960s.” (History of Nature feature.)

A full appreciation from Nature will follow shortly. Meanwhile, here is what the world is saying.

Without too much trouble I could probably fill blogs for a month with tales of John: of waiting at the typesetter while he finished an editorial way beyond deadline; of a plan to visit Mexico together when we wined and dined the very attractive press attache at the Mexican Consulate; of how he regularly set fire to his waste-paper basket. Of being sent to the wine bar with a fiver for a bottle of Chateau Thames. Of him disappearing on a Friday night and saying, as the door closed, that he wanted a thousand words from me by Monday for the following week’s issue – on anything I pleased. Of many cases of exasperation and irritation, and many more acts of kindness.

- Henry Gee, Nature editor

He was one of those fellows who shaped the direction of science for quite a long period of time with the power of one of the most influential science journals in the world. I suspect every scientist of my generation read his editorials in our weekly perusal of the journal.

- PZ Myers, Pharyngula

One of the toughest adversaries I’ve ever wrangled with is Sir John Maddox. He was hard-headed, scarily knowledgeable, hyper-articulate, unfailingly gracious even as he ripped you a new one.

- John Horgan, Director of the Center for Science Writings at Stevens Institute of Technology

As Editor of Nature, he restored the journal to an unchallenged position as the place to publish interesting research quickly, and did so at a time when Britain’s influence in world science was otherwise declining. His judgments, sometimes quirky but never dull, were always backed by persuasive argument and a sense of humour.

- The Times

It was a mark of his skilled editorship that Nature could publish a paper on, say, the Loch Ness monster without sacrificing its authority.

“He took command of Nature in a big way,” the evolutionary biologist Richard Dawkins said. “He had a tremendous grasp of science in the full range, from physics to biology to public affairs as they affected the world of science.”

Martin Rees, the president of the Royal Society and Britain’s astronomer royal, called Mr. Maddox “a dominant figure,” adding that “he helped establish Nature’s status internationally and built it up by developing supplements to increase its coverage.” After retiring as editor in 1995, he assumed an influential elder statesman role, acting, Mr. Rees said, “as a general guru of science and scientific policy.”

- NY Times

"He adored science and talked about it all the time," she [his daughter, Bronwen Maddox] says. "He was enormously enthused by it. He was a physicist, and took to the biological sciences with enthusiasm, but I think his heart stayed in physics."

- Scientific American

Would you Adam and Eve it? Robot scientists - named Adam and Eve - could soon be after your research jobs.

According to a new paper in Science, an autonomous robot can conduct its own experiments and has now come up with its first results. Ross King, of Aberystwyth University, and his colleagues report that their robo-researcher ‘Adam’ has “generated functional genomics hypotheses about the yeast Saccharomyces cerevisiae and experimentally tested these hypotheses by using laboratory automation”.

The team set Adam to work finding genes for “orphan enzymes”. These are as-yet undiscovered genes for enzymes thought to catalyze reactions that occur in yeast. King told the Times:

Because biological organisms are so complex it is important that the details of biological experiments are recorded in great detail. This is difficult for human scientists, but easy for robot scientists. Yeast is well understood. It’s been studied for over 100 years. We knew this enzyme must be there, but we didn’t know where.

Video games might improve your eyesight, according to a paper published by Nature Neuroscience.

Daphne Bavelier, of the University of Rochester in New York, and colleagues found that study subjects who played action video games (either Unreal Tournament 2004 or Call of Duty 2) had improved ability to detect small changes in shades of gray on a uniform background, so-called ‘contrast sensitivity’. Those who played a more sedate game (The Sims 2) showed no improvement.

“Unfortunately, contrast sensitivity is one of the aspects of vision that is most easily compromised,” says Bavelier (Independent). “This problem affects thousands of people worldwide, including those with professional activities requiring excellent eyesight, and ageing populations, along with individuals who are clinically evaluated for vision problems such as amblyopia.”

The new study suggests playing certain video games might help with contrast problems. After 50 hours of playing the action-game group had improved their ability to see shades of gray by 43%.

“[Contrast sensitivity function] improvements are typically brought about by correction of the optics of the eye with eyeglasses, contact lenses or surgery,” the researchers write. “We found that the very act of action video game playing also enhanced contrast sensitivity, providing a complementary route to eyesight improvement.”

Gary Rubin, of the University College London Institute of Ophthalmology, told the BBC, “Contrast sensitivity is a very basic visual function, and usually they are more difficult to alter in adulthood. This is a small study, showing a small effect, but it was carefully done, and merits further investigation.”

Journals should be routinely checking papers they publish for signs of plagiarism, a team of American researchers is demanding.

In a commentary paper published in Science the team headed by Harold Garner, of the University of Texas Southwestern Medical Center, report their checking of similar citations in the Medline database. They found 212 pairs of articles with “signs of potential plagiarism” using a computer programme called eTBLAST.

“We have just started to scratch the surface, we anticipate finding hundreds to thousands more cases. It is definitely the tip of the iceberg,” says Garner (Globe and Mail).

Garner previously used the same programme on Medline to find duplicate citations and found thousands of cases of potential plagiarism. Writing in Nature in January 2008 Garner and fellow researcher Mounir Errami wrote:

We find it odd that automated text-matching systems are used regularly by high schools and universities, thereby enabling us to hold our children up to a higher standard than we do our scientists. In our view, it would be fairly simple to fold these tools into electronic-manuscript submission systems, making it a ubiquitous aspect of the publication process.

Now they are again pushing the issue in their new piece, and reporting the responses of editors and authors of both the original paper and the suspected plagiarism.

A German group named after a famous heretic has decided to celebrate Darwin’s 200th birthday by campaigning to have the Ascension Day public holiday renamed ‘Evolutionstag’ (Evolution Day).

Ascension Day is when many Christians celebrate supposed return of Jesus to heaven, it normally falls in May. As Spiegel notes in its coverage of the campaign, most holidays in Germany have Christian roots, although a third of the population is atheist.

The Giordano Bruno Foundation, which is behind Evolutionstag, says it is time for a secular holiday. (Bruno advocated heliocentrism and was burned as the stake in 1600, although many believe this was more to do with his unorthodox views of god than his astronomy musing.)

To spread their message they’ve made this song.

This is the UC Berkeley entry in the American Chemical Society’s ‘What is Nano?’ contest. "We put a lot of work into making something we hoped would be accessible and enjoyable for everyone we know who doesn't spend their life studying nanoscience," says Patrick Bennett, the scientist who directed the video, told Wired.

The next item for your delectation is the welcome return of Richard Alley, who some of you may remember for his “musical review about the problem of scarce resources” set to the tune of Proud Mary and others may remember for his glacial calving work.

As it gears up to build another generation of nuclear plants, Britain is expecting to close down its £470 million facility at Sellafield which converts plutonium waste into new nuclear fuel, The Guardian reckons. The plant, which was launched 10 years ago and is the only one in the country, was supposed to help use up plutonium recovered from nuclear waste by turning it into MOx fuel (mixed oxides of uranium and plutonium). It’s never been a success, reprocessing less than 3 tonnes of fuel a year since it started, and being dogged by embarrassing technical problems.

According to a strategy document recently published by Britain’s Nuclear Decommissioning Authority (NDA), which is wondering what to do with plutonium:

NDA have reviewed SMP [the Sellafield MOx plant] and do not believe that it provides either the capacity or longevity to be used for the UK civil stockpile and the recycle options that NDA has considered assumed that plutonium is either sold direct or that MOx is fabricated in a new plant.

Industry sources say that means curtains for the old MOx plant, The Guardian says, though the NDA says it hasn’t made a formal recommendation yet.

A group of UCLA scientist think they may have answered a question that has baffled the most powerful military machine on Earth: where is Osama bin Laden?

“In informal conversations in the Geography Department at UCLA, we began to ask ourselves if the biogeographic theories we use every day – theories that predict how plants and animals distribute themselves over space and over time – employed in conjunction with publicly available satellite imagery, could shed some light on this question,” write Thomas Gillespie and colleagues in the MIT International Review.

“… By bringing these methodologies to bear, it is our hope that a long overdue debate might bring bin Laden back to the fore of the public consciousness – and possibly to justice.”

Combining facts about his behaviour and last known whereabouts with satellite images, the researchers narrow down his possible location to three building in the northwest Pakistan town of Parachinar. "If he's still alive, he honestly could be sitting there right now," says Gillespie (press release).

Kim Rossmo, of Texas State University in San Marcos, told USA Today he was not entirely convinced.
“It’s important to think outside the box, and this is an innovative idea worth more pursuit,” says Rossmo. “However, the authors are much too certain of their conclusions. The idea of identifying three buildings in a city of half a million — especially one in a country the authors have likely never visited — is somewhat overconfident.”

Now that they can do no science till their giant particle smasher is fixed, the Large Hadron Collider scientists are finding other ways to keep people interested.

Sergio Cittolin, who works on the Compact Muon Solenoid detector, has been sketching the different elements of his equipment “in the style of Leonardo da Vinci”.

Although they seem to have only appeared on the CERN website at the end of January, some of these drawings were originally featured in Physics World last year. They also grace the CMS website and are too cool not to share here.

Dan Brown fans will surely be thrilled to find two of their author’s interests combined.

Iran’s announcement that it has successfully put a satellite in orbit has successfully triggered the fear in many.

The satellite is named Omid (Hope), and according to Reuters is for research and telecoms. Manouchehr Mottaki, the Iranian Foreign Minister, commented, “Iran’s satellite technology is for purely peaceful purposes and to meet the needs of the country.”

However France, American and UK are already expressing concerns about Iran’s apparent space-ability, mainly because the technology used could also be used to make ballistic missiles (BBC).

You can do the same, just by taking a look at Google Earth’s latest addition. (Check out Climate Feedback last year on Google Earth's climate-related updates). It’s a very cool update that allows you to scoot around under the sea, and take a look at the sea floor, or at least a representation of it based on seismic data. Can you guess what it’s called? Google marketing people have done themselves proud this time, yes, it’s called Google Ocean!

This Very. Exciting. News. has set the internet alight with stories about the project.

Sylvia Earle, oceaneer extraordinaire introduces the project in a video neatly slotted in at the Guardian, and a great quote of hers is highlighted by Deep Sea News: “Anyone can discover in a few minutes what took me 50 years to understand.” DSN are in turn highlighting the Google Ocean live blogging epic by Danny Sullivan.

The application allows you to spin the globe round, take your pick of underwater treasure you want to find, and zoom in (or dive down) to check out how the land lies. It’s neat, and the Googlers have added tidbits of information about some of the features you might see.

The data has come from a load of research institutes, and the EU is also claiming a stake in the project.

Take a peek, but look out for the vampire squid, apparently lurking there somewhere…

America is getting a new university. A rather strange sounding university.

Based at NASA’s Ames facility in California, the Singularity University has been inspired by the writing of ‘futurist’ Ray Kurzweil. This summer students – who may number 30 or 120 – will start work at the university, which is backed by Google (who else) to the tune of $1 million.

“Singularity University aims to assemble, educate and inspire a cadre of leaders who strive to understand and facilitate the development of exponentially advancing technologies and apply, focus and guide these tools to address humanity’s grand challenges,” says the institution’s website.

You might recall a neat site we profiled last July that ranked journals not by citations but by value for money—the eigenfactor.

Well the team behind the eigenfactor have not rested on their laurels. Instead, they have teamed up with data visualization whiz Moritz Stefaner of Well-formed data to make super-sexy looking visualizations of how and how much journals and fields cite one another, which journals are the best value, and how a given journal's importance has risen and fallen over time.

See them in all their glory at well-formed.eigenfactor.org and read Stefaner's notes on how he approached the project at his blog.

Carl Bergstrom, the lead player in the eigenfactor team, says the intended audience is curious scientists as well as data-visualization enthusiasts. "What we are experimenting with here is how good algorithms and good data can combine with intelligently designed and aesthetically beautiful ways of displaying that data."

Bergstrom left all the aesthetic decisions, such as which colours to use, strictly to Stefaner. "Moritz is the designer," he says. "I shouldn't be allowed to do these things. My wife could tell you that."

Meanwhile, in other impact-factor news, Public Library of Science ONE has recently announced (registration required) that it will add a grab-bag of "alternative impact data" from Scopus, user ratings, press coverage and the like to each article. The Scientist quotes Peter Binfield, the journal's managing editor, as saying "Our idea is to throw up a bunch of metrics and see what people use."

Update: Carl Bergstrom has asked us to make the following clear: "We also rank by citations. We just have additional features that let you take price into account. But the basic Eigenfactor scores as visualized at the new site are purely citation-based, and independent of price." Apologies for any confusion. Ed.

A new world record has been set for solar cell efficiency, or so we are told by researchers at the Fraunhofer Institute for Solar Energy Systems, Germany. They have revealed a triple-junction cell that has a conversion efficiency of 41.1% (press release).

Solar cell efficiencies are notoriously hard to pin down. Claims are often made, but not considered ‘official’ until they are independently verified by a recognised body. A quick search online, for example led me to a claim from a consortium that includes the University of Delaware of a cell with 42.8 % efficiency.

So what’s the real answer? And do these incremental advances mean anything?

The ever-vocal Project on Emerging Nanotechnologies, based in Washington, DC, is the latest organisation to produce a report bemoaning the lack of regulation of engineered nanoparticles in commercial products (press release).

This time, the US Food and Drug Administration are under fire for not being up to the task. The report “A hard Pill to Swallow: Barriers to Effective FDA Regulation of Nanotechnology-Based Dietary Supplements” pulls no punches, kicking off in the summary with the following: “This paper addresses the issue of whether FDA is equipped to meet the emerging regulatory challenge of dietary supplements that use engineered nanomaterials. The short answer is no.”

The three main problems the report authors, William Schultz from legal practice Zuckerman Spaeder and his colleague Lisa Barclay, identify include:

1. FDA does not have the capacity to identify nano-based dietary supplements that are being developed and marketed, unless manufacturers submit to the pre-market notification process for new dietary ingredients.
2. To the extent that FDA is aware of nano-based dietary supplements, it has little regulatory authority over them.
3. Even if it were granted increased regulatory authority, FDA lacks the scientific expertise and resources to effectively regulate nanomaterials in supplements.

The proportion of videos on YouTube concerned with performing animals and feats of dance has declined very slightly this month. The reason for this is that Nature has launched its very own channel, bringing you all that is best in science.

Where else can you watch items on genome analysis of the duck-billed platypus and new interpretations of the mysterious Antikythera Mechanism alongside whale evolution and mega-impacts on Mars? Nowhere, that’s where.

Researchers have released a map showing where in the US you are most likely to die in a natural disaster. Such acts of God do not, of course, smite the country evenly.

The survey, published in the International Journal of Health Geographics yesterday, puts the worst mortality statistics in the South, thanks to tornadoes and other deadly weather. Heat waves and droughts made the northern Great Plains another danger zone.

Heat and drought were, in fact, the country's biggest killers, accounting for 19.6% of all hazard deaths in 1970-2004. Close behind were other forms of severe weather - thunderstorms, blizzards, and such like.

Brits and Kiwis got curious about the Large Hadron Collider this year, according to newly released search stats from Google. But nobody else did.

After a press-sweeping September debut - and an almost immediate breakdown from which rumours are still rippling - "large hadron collider" was the 6th-fastest-rising search term of 2008 in the UK, and came in 10th in New Zealand (fastest rising = largest increase in searches since 2007). It didn't make the top 10 list in any other country.

The LHC-equivalent 6th fastest riser for the US was "fox news"; for Canada it was "free movies".

No other science term made it onto the lists - unless you count "earth day", which was 4th for Hong Kong googlers (followed, for reasons opaque to me, by "alexander graham bell", "marc chagall", and "diego velasquez"). In Australia "underbelly" was 10th, but disappointingly, it's a popular TV show, not an epidemic of seedy corruption.

If you believed some of the more sensationalist headlines, you might think that a commentary paper published in Nature yesterday was urging everyone to go out and source illegal drugs to boost their brain function.

Sample headlines include ‘Let all pop pills for brain, experts urge’ and ‘Uppers for everyone, scientists say’. Admittedly, that is catchier than the title of the article in question: ‘Towards responsible use of cognitive-enhancing drugs by the healthy’.

“The article, while libertarian in spirit, is absolutely not saying: ‘use these drugs, everybody’,” says Philip Campbell, one of the paper’s authors and editor of Nature.

“My advice is to avoid taking such drugs unless you have been prescribed them. It is a serious felony to sell such drugs off-prescription in the US; in the UK, Ritalin, for example, is a class B drug, so that un-prescribed possession is punishable by prison and a fine. Furthermore, these drugs have undergone no clinical trials for use by healthy people. And they do have side-effects.”

French scientists today announced plans to clone black truffles and grow them in a lab (Financial Times).

Marking the start of truffle season, the French region of Corrèze launched a three-year plan that it hopes will revive supplies of the precious fungus - which fetches €1,000 ($1,265) per kilo at market but is harvested less and less. FT reports:

Their goal is to unlock the secrets of black truffle production - the soil, climate or the trees - and hopefully revive an endangered industry by producing a more consistent crop.

The project will involve culturing cloned truffles together with tree saplings in rows of sterile test tubes until they form their crucial symbiotic relationship, a process that can take up to a year. Once the pair is established they will be planted out to mature naturally.

The Times and the Telegraph pick up the story (the latter in a close paraphrase of the FT).

Says Jacques Pebeyre, an octogenarian author and truffier known as France's 'truffle king', "I am not against helping nature." But, he adds, "we need to know how good these [cloned] truffles will be. In the end it all depends on that" (FT).

The University of Bath has unveiled the latest iteration of what may be the first robot that can both jump and roll.

PhD student Rhodri Armour’s ‘Jollbot’ could be useful for space exploration, says the university, as it is simpler than a legged design and can overcome larger obstacles than a similar sized wheeled vehicle could achieve (press release, 2005 meeting presentation).

“Others in the past have made robots that jump and robots that roll; but we’ve made the first robot that can do both,” says Armour. “Before jumping, the robot squashes its spherical shape. When it is ready, it releases the stored energy all at once to jump to heights of up to half a metre.”

Jollbot was previous announced in a 2007 paper, when Armour told PhysOrg, “For earth-bound uses, there are a variety of other possible applications that involve locomotion over random or rough terrain. Typically these would involve exploration and could occur in places such as volcanoes, caverns, mountainous regions, or more structured rough environments such as urban areas with stairs and other obstacles. Other applications could be for entertainment, such as tourist guides.”

Of course, if Jollbot does go into space it may meet some very similar things already out there...

A clever camera setup in a Swedish neuroscience lab produces the sensation of swapping bodies with a mannequin or, perhaps even more uncannily, with a cognitive neuroscientist, according to a paper in PLOS One(press release).

This is not a major new finding, but rather – as Reuters notes - a high-tech extension of an old trick in which subjects are made to perceive a rubber hand is their own. The paper describes the technique:

Two CCTV cameras were positioned on a male mannequin such that each recorded events from the position corresponding to one of the mannequin’s eyes. A set of head mounted displays ... connected to the cameras was worn by the participants, and connected in such a way that the images from the left and right video cameras were presented on the left and right eye displays, respectively, providing a true stereoscopic image. Participants were asked to tilt their heads downwards as if looking down at their bodies. Thus, the participants saw the mannequin’s body where they expected to see their own.

We used a short rod to repetitively stroke the participant’s abdomen, which was out of view, in synchrony with identical strokes being applied to the mannequin’s abdomen in full view of the participant.

How would nature do it? That's the premise of the field of biomimetics or biomimicry, which draws on designs and materials that lifeforms have evolved over the course of millions of years.

Now Autodesk, the industry leader in Computer Aided Design software and the maker of Autocad, has got together with Janine Benyus naturalist and founder of the Biomimicry Institute in Missoula Montana. Together they’ve created a free online database called Ask Nature, where they hope to compile nature's solutions to design and engineering challenges, for creators of all stripes to draw on for inspiration.

“This free database is the only public-domain online library of its kind in the world, where architects, designers and engineers can search for and study nature’s solutions to design challenges – learning, for example, how organisms filter air and water, gather solar energy, and create non-toxic dyes and glues,“ they say.

The dangers of swimming too fast and not looking where you’re going are ably illustrated by this swordfish (or possibly marlin), found wedged into a blow out preventer on the Atwood Eagle oil rig. Not to worry though fish fans, a friendly underwater robot comes along to rescue it.

“This is an example of the things that make the offshore oil industry fun,” says the Peripatetic Engineer blog.

A skull from Frombork cathedral in Poland has been identified as that of revolutionary astronomer Copernicus.

Marie Allen, of Uppsala University, says DNA from the skull is a match for DNA from hairs found in books owned by Copernicus, whose book De revolutionibus orbium coelestium started the movement to viewing the sun – rather than the Earth – as the centre of the solar system.

“The two strands of hair found in the book have the same genome sequence as the tooth from the skull and a bone from Frombork,” she says (AFP).

Polish police have used the skull to create a reconstruction of how its owner might have looked. This, says AFP, “bore a striking resemblance to portraits of the young Copernicus”.

Television might be about to get geekier.

The US National Academy of Sciences has created an initiative that will link TV and movie directors with scientists and engineers to incorporate more accurate science content into entertainment: the Science and Entertainment Exchange.

"By building strong connections between the entertainment and science communities, we're hoping to provide an important service to both Hollywood and the viewing public,” says NAS president Ralph Cicerone (press release). Cicerone says he thinks initiative should allow the public to get involved in the latest advances in science, technology and medicine through television and film.

More and more shows are incorporating science into their content, especially forensic investigation and medical shows like CSI and ER. Films like A Beautiful Mind and Mission Impossible are also heavy on science and technology while Star Trek and the like use the fundamental principles of science to push the frontiers into science fiction.

Recently, Dwayne Rooke, the chef at the Davis Station science base in Antarctica, was seriously injured in an all-terrain vehicle accident and had to be evacuated to Tasmania. This was no mean feat.

A ski-eqipped LC-130 Hercules transport plane was dispatched from McMurdo station, which is across the continent and now experiencing nasty spring weather. A temporary sea ice runway was prepared at Davis station for the rescue and penguins were kept off of it. The day after the plane arrived at Davis, it left again for Tasmania (NSF press release, Australian Antarctic Division press release, article from The Age).

When Werner Herzog went to Antarctica to make Encounters at the End of the World he was a bit disappointed at how mundane life at the bottom of the world seemed. Stations are often dirty and scruffy. But science at the end of the world has not yet become a tame affair.

A 16-year-old frozen mouse carcass made headlines yesterday when scientists announced the rodent was the first frozen animal to be cloned. In a paper published online by PNAS, Teruhiko Wakayama of RIKEN in Yokohama, Japan, and his colleagues report that they were able to produce healthy clones from the rodent’s frozen brain cells.

Frozen cells have been cloned before but those cells were specially treated with chemicals that helped protect them from the damaging effects of freezing. Wakayama’s paper is the first to successfully clone a frozen animal that was, from what I can tell, pretty much just placed in a paper box and plunked straight into a –20ºC freezer in the early 1990’s.

The authors are excited about the possibility of using the technology to resurrect the woolly mammoth from carcasses frozen in Arctic tundra, but acknowledge the possible technological leap between using a 16-year-old and a 40,000-year-old frozen body. (I won’t pretend to understand the obsession with the woolly mammoth, but have acknowledged that the obsession is very real ever since I learned there is a black market for woolly mammoth parts run, at least in part, by the Russian mafia.)

A scientist has seen his research become an internet hit after a video of his work was set to the Benny Hill theme music.

David Scholnick, who works at Pacific University in America, was using a treadmill to assess the health of shrimps. Healthy shrimps should run fast, unhealthy shrimps should run slower.

“The healthy shrimp ran and swam at treadmill speeds of up to 20 metres per minute for hours with little indication of fatigue,” he says (Daily Mail). “[A] shrimp dealing with an infection is less active and limited in its ability to migrate, find food, and avoid being eaten. As far as I know this is the first time that shrimp have been exercised on a treadmill and it was amazing to see how well they performed.”

Then someone leaked a video of the running shrimp onto the internet. This was way back in 2006 so it’s not quite clear why a number of newspapers are covering this story now. Still, the video is amusing enough to be its own justification.

The video of the running shrimp has become a smash hit, with many versions being set to music. Embedded above is one of the most popular, with over half a million people watching it since November 2006.

“'So many people have logged on to see it which I suppose is kind of funny - I guess people are fascinated,” Scholnick told the Mail. “I guess people find the prospect of watching a shrimp exercise on a treadmill amazing.”

The pair of 800 pound gorillas that are Microsoft and Google are shaking the cages of convention in traditional disease research. This week, the charity arms of both - the Bill and Melinda Gates Foundation and its Sergey and Larry counterpart Google.org - announced millions of dollars for blue skies research, along the lines of the US military's DARPA whose motto has been to support “revolutionary, high-payoff research that bridges the gap between fundamental discoveries and their military use.” Likewise, Google and Microsoft are trying to attract new blood and ideas, for medical payoffs in the fields of detecting, preventing, treating, and controlling killer diseases such as malaria, tuberculosis, HIV/AIDS and pandemic flu.

Today, Microsoft announced the 104 winners, from 22 countries and six continents (see graphic below), of a competition in novel ideas for global health (list of winners). “Projects cover a wide range of innovation, including a “mosquito flashlight” to prevent malaria transmission by disrupting wavelengths, self-destructing TB cells, and studying anti-infective properties of the eye to help prevent HIV/AIDS and other infectious disease,” the company says in a press release.

The Large Hadron Collider has already been fired up and it has already broken. Yesterday the giant particle physics experiment was also formally inaugurated as Swiss president Pascal Couchepin, French prime minister François Fillon and science ministers from across the world met at CERN, the European Organization for Nuclear Research in Geneva.

In an obligatory nod to the world’s financial woes, Fillion said, “The financial crisis that is currently raging shows us the most destabilising face of globalisation. But the LHC is an example of its most promising aspect.” (AFP.)

Of course the machine is not working at the moment, after a massive amount of liquid helium leaked from its cooling system. This fact could hardly be glossed over and Raymond Orbach, US undersecretary for science at the Department of Energy, told AP, “Frankly it was a surprise that it worked the first time without a glitch.”

However Arden Bement, director of the National Science Foundation, added, “I have no doubts they'll get back into operation within three to four months.”

The Daily Telegraph is among papers to note that those attending the reception were treated to a banquet of ‘molecular cuisine’: “molecular egg curdle and ice-cream mixed with liquid nitrogen, created by two of the world’s best chefs Ettore Bocchia of Italy and Ferran Adria, who runs El Bulli restaurant in Spain”.

Liquid nitrogen? Let’s hope that none of that leaked...

This strange contraption is the result of a collaboration between Australian artist David Rogers and US Geological Survey scientist Andy Michael. The ‘seismic art installation’ displays Californian earth quakes in real time by shaking its three-metre high steel rods.

The Parkfield Interventional EarthQuake Fieldwork (PIEQF) exhibit receives data on all earthquakes above magnitude 0.1, of which there are around 40 in the Golden State every day.

Michael and Rogers say they hope the work will help people accept and understand the risks posed by earthquakes.

“The Parkfield installation embodies the extra dimension that art brings to science, helping to visualize what's going on below the surface in a way science can't on its own,” says Michael (press release). “David’s art brings earthquakes that happen under California every day to the surface and makes them real and visible for all to see. His work gives everyone a deeper appreciation for how the earth works, and why they need to prepare for the inevitable large and damaging earthquakes.”

If you can’t make it out to Parkfield you can watch on the webcam (note that PIEQF ‘sleeps’ from 9.30 in the evening to 6.30 in the morning).

Warwick University expects more than 200 human body parts to arrive next week. You might think that wasn’t out of the ordinary, but this time there’s a twist.

The institution’s medical school has purchased “plastinated” teaching aids costing £400 000 from the controversial Gunther von Hagens. Von Hagens, who works out of Guben, Germany, is famous for carting exhibitions of preserved and carefully chopped up dead folks around the world, occasionally displaying them riding dissected horses or playing chess (press release).

Warwick’s anatomy students will be under strict orders on how to handle the expensive flesh, which should stay in one piece (or however many pieces are intended) for about a decade, according to the university press office. Head of department Peter Abrahams, apparently trotted around the workshops of various suppliers, testing their embalmed bits before agreeing to the deal with Dr Death (as von Hagens is weirdly proud to be known).

The Telegraph just published a profile of von Hagens and his German factory, with its blood-red floors and 150-odd workers, who boast jobs as peculiar as preparing Santa Claus’s lungs.

Intriguingly, the obsessive anatomist was once sold by East Germany to West Germany (West Germany purchased the release of about 30,000 political prisoners from East Germany - Times), and 8,000 people have volunteered to have their corpses dunked in a bath of acetone, injected with silicone rubber and then cured by him or his craftsmen.

Alongside the masses of IT news and the occasional science story the mysterious and top-secret Google algorithms seem to think horoscopes now count as science.

Yesterday UPI’s ‘Your Daily Horoscope’ was the second science story at a little after nine (image). Today the LA Times’ horoscope nestled neatly between news of Microsoft R&D spending and cheap DNA sequencing (image).

Wow, here’s an invention I never realised we needed: The world’s fastest barcode reader.

But I'm just showing my ignorance – today I have learned that barcodes are used much more widely than just at the supermarket checkout.

Yes, barcodes are one of the underpinning infrastructure technologies of our society. Sorting things out everywhere from shops to post rooms to blood banks. Current readers use either a mechanically scanned laser – the reflected light bounces back and gives the reading – or an optical scanner that takes a picture of the barcode. The scan rates of these lasers is about 100 – 1000 scans per second, and require the use of mechanical scanners and lots of optical-to-electrical converters.

But if that’s not fast enough for you, check out this paper in Applied Physics Letters (paper, press release)by Keisuke Goda and colleagues at UCLA. They use a fancy laser technique, where a laser pulse has the barcode’s image mapped onto it, and this in turn is mapped onto another waveform that is read with great speed by a single, stationary, optical-to-electrical converter. The limiting step is the speed of the laser pulse.

They reckon they can get a bar code reader that scans at a rate of 25 MHz – 10,000 times faster than the old methods Goda says, and in future this speed could be even faster. They say that faster and faster readers are needed by industry. PI Bahram Jalali explains: " "Eliminating the CCD camera and the mechanically steered mirrors from bar code scanners can prove valuable in applications that demand high-throughput bar code reading, such as industrial monitoring and retail supply line management."

Hold on to those solar panels or they might show up on eBay. As energy prices soar and consumers turn to the Sun for their power, opportunistic thieves are cashing in on the new market by dismantling and reselling solar panels.

"I wouldn't say it's pervasive, but it's going on," California Solar Energy Industries Association executive director Sue Kateley told the Contra Costa Times in August. According to UK paper the Guardian a rash of thefts in California has led one wag to coin the term ‘grand theft solar’

California is the US leader for solar panel installations, with 33,000 across the state, the New York Times and the Guardian report. It’s no surprise, then, that California is also the US market leader for solar panel thefts. Note that figures are hard to come by and cases have been reported in Oregon, Minnesota and even in Africa.

On 22 September, in fact, the South African Sowetan reported that police caught an off-duty officer in Thohoyandou, Limpopo possessing solar panel band cutting equipment and suspected stolen property. Similar property thefts were reported by The New Vision Online, a Ugandan Web site.

This year saw the 58th Meeting of Nobel Laureates descend on the island of Lindau, Germany. The meetings are supposed to allow young scientists to meet the giants of their field.

Nature sent a film crew to the island to make the first ever Nature documentary. Starting from October 3rd you can see five interviews in which students question Nobel Laureates David Gross, George Smoot, Gerardus t’Hooft, John Hall and William Phillips.

If you can’t wait there’s a teaser trailer already available here.

Via Andrew Revkin’s DotEarth blog we meet Richard Alley of Penn State, aka The Singing Climatologists. This is ‘Rollin’ to the Future’, described by Alley as “a musical review about the problem of scarce resources”.

Revkin says:

Besides being a lead author on several reports from the Intergovernmental Panel on Climate Change, Dr. Alley led one of the groups that first discerned in Greenland’s ice layers how the climate has seen extraordinary jogs in temperature, particularly shortly after the end of the last ice age. ... Now he’s moving into multimedia communication on climate, and earth sciences more generally, not just with video, but with a guitar.

For our younger readers, this is what he’s referencing although this version is clearly better.

The media feeding frenzy that is the British Association Festival of Science has kicked off. Katrina Charles is there for Nature and has thus far enlightened us about fossilised forests in Illinois coal mines and why science in science fiction films is a bit silly.

There’s far more to cover than one person alone can manage. Here’s a round up of the rest...

Via Steinn Sigurðsson’s Dynamics of Cats blog this rather excellent piece of Friday-fodder has surfaced. Philosopher of science Santiago Ginnobili and his colleague Christián Carlos Carman have constructed this awesome demonstration of the power of epicycles.

For those of you not au fait with ancient cosmology, epicycles are a way of explaining the motions of planets using only perfect circles. Assuming planets moved in perfect circles did not explain what was seen in the sky, so astronomers added secondary and tertiary circles, smaller and smaller, to try and create patterns which agreed with observation.

In theory any curve can be constructed using this method, if you’re prepared to add enough circles.

This exercise appears to be tied up with ideas of refutability and falsification in science, but to be honest my language skills aren’t up to translating philosophy of science papers in other tongues. Just enjoy the video for now.

Tests carried out on the two mummified foetuses found in the tomb of King Tutankhamun are beginning to yield results.

Research presented at the pharmacy and medicine in ancient Egypt conference at Manchester University, UK, earlier this week show the children could have been twins despite one being much larger than the other.

The results add weight to suggestions that the stillborn foetuses were the teenage Pharaoh’s children, and is due to be published in the journal Antiquity in January 2009.

Last month, Egyptian scientists announced they were to conduct DNA paternity testing on the foetuses. The results are due December. The foetuses were found by Howard Carter when he discovered the King Tut’s tomb in 1922, but very little has been found out about them since.

A solar powered plane has set a new record over the desert of Arizona, staying aloft for 83 hours and 37 minutes. Importantly, this means it stayed up for three nights.

The Zephyr beat a previous official world record for unmanned flight of 30 hours set by the Global Hawk plane in 2001 and also beat its own previous unofficial record of 54 hours. As this Zephyr flight does not meet all the requirements of the Federation Aeronautique Internationale the record remains unofficial, notes the BBC.

Although it might eventually be used for research purposes such as earth observation, those most likely to see the Zephyr first used commercially are those unfortunate enough to be in war zones. Its manufacturer QinetQ is a mainly military engineering company that was spun out of the British military a few years ago.

“In addition to setting a new unofficial record, the trial is a step towards the delivery of Zephyr's capability for joint, real-time, battlefield persistent surveillance and communications to forces in the field at the earliest opportunity,” says Simon Bennett, managing director of QinetiQ’s Applied Technologies business (press release).

News rampage, that is. The world’s press has gone into something of a frenzy over a report in New Scientist of a robot guided by “rat brains” – more accurately rat neurons in a dish.

This is just a small sample from around the globe: Wired, News.com.au, India Times, Telegraph.

This experiment is somewhat different from the monkey-brain controlled robotic arm described in Nature in May and the earlier robots controlled by whole monkey and lamprey brains. In these new experiments the response of disembodied rat neurons in a dish were used to control a free-roaming robot called Gordon.

Sat-Nav in a wristwatch, pretty high-tech? Apparently, not necessarily. Sat-Nav wristwatches have been around since 1920.

This nifty device, which provides scrolling directions for multiple locations*, is one of 50 weird and wonderful labour-saving devices that have gone on display at the British Library.

It is not clear if this device can also provide traffic updates.

Other gadgets, some of which the Daily Mail provides pictures for, on display include:

The two handled self-pouring teapot (1886)
Clockwork burglar alarm (1852)
Grenade to put out fires (1890)
Mechanical page-turner (1890)
The automatic nose hair cutter (1920)

And according to the Telegraph there are also "Go no further" honeymoon garters.

The collection is provided by Maurice Collins, “a retired businessman from Muswell Hill, London, who has cherry-picked 50 must-have items from his collection of 1,400 historic gadgets to show off at the British Library Business and Intellectual Property Centre”, says the Daily Mail.

On the front page of wikipedia today you may have noticed a small item about WRNY, “an AM radio station ... started by Hugo Gernsbacks Experimenter Publishing Company to promote his radio and science magazines”.

These magazines started up over a hundred years ago in April 1908 with the first edition of Modern Electrics, which later became Modern Electrics and Mechanics. Gernsbacks continued with The Electrical Experimenter in 1913, which became Science and Invention in 1920.

“Not only did this fill America’s proto-geeks with dreams of wireless and electrical power machinery, it published Gernsback's hard-SF novel Ralph 124C 41 + and arguably foreshadowed the entire genre of technically oriented science fiction,” says the Magazine Art website.

Ok, we’ve missed the anniversary in April but this was too good not to bring to your attention: the Magazine Art website has a complete cover gallery of these magazines. If you have any time on your hands have a browse and see how the future looked back in the last century.

Following on from Polish rejection of attempts to analyse the DNA of Chopin, a woman who says she is the daughter of Salvador Dali has started another testing debate.

A woman identified in the Daily Telegraph as Pilar A says the artist is her father but initial DNA testing on skin and hair from his iconic moustache has proven inconclusive. She has called in the lawyers and says she may even try to exhume Dali’s remains, having not been satisfied with the response of his estate to her attempts to establish paternity.

Pilar A says more DNA testing has been done by the estate, but she has not been told of the results by the estate, controlled by Dali’s friend Robert Descharnes. However Robert Descharnes’s son is quoted as saying that the doctor undertaking the paternity test told him verbally there was no Dali link to Pilar A (the Telegraph calls the son Richard; El Mundo calls him Nicolas).

And, proving beyond doubt that internet language translation cannot be trusted, ABC Spain (via Google language tools) provides us with this appropriately surrealist gem as the intro of their coverage:

Only ‘you lack the mustache’ (of the Salvador Dalí, which hedgehogs into the sky), confesses that he told Robert Descharnes-friend and collaborator of genius ampurdanés for forty years-nothing else see it.

Researchers from the University of Twente in the Netherlands have launched a test of ‘air-purifying’ concrete.

Titanium dioxide in the bricks helps sunlight convert nitrogen oxides into “harmless nitrate”. When the rains come this then washes the bricks clear (press release). It’s not clear if the amount of nitrate being produced would be a pollution problem, as is the case with nitrates in agriculture.

The bricks are based on Japanese technology (possibly this tech) which has been further developed by the Twente researchers, says the university. One road in the town of Hengelo will be paved with the eco-bricks and another with normal bricks. The researchers will monitor pollution on both roads.

This isn’t the first set of air-scrubbing concrete out there. The idea has popped up in Italy, where it featured at the Venice Biennale.

Want to know more? Check out this paper from Belgian researcher Anne Beeldens: An environmental friendly solution for air purification and self-cleaning effect: the application of TIO2 as photocatalyst in concrete (PDF).

At the risk of turning The Great Beyond into a celebrity gossip sheet, which extravagantly-masked leader is currently having paternity tests conducted on two children suspected of being his offspring?

This is the widely reported news that Egyptian scientists are conducting DNA paternity tests on two foetuses found in King Tutankhamun’s tomb in the Valley of the Kings. The stillborn foetuses were found by Howard Carter when he discovered the tomb in 1922 and have remained in storage ever since, having never been put on display or studied (AP).

It has always been assumed that the children were his, DNA testing should settle matter (and lay to rest questions over his fertility).

The testing is part of a larger program to test the relations between hundreds of Egyptian mummies. This is of immense interest to Egyptologists as the precise identity of Tutankhamun’s parentage is unclear.

An unintended consequence of electric and hybrid cars was reported earlier this year: these environmentally-friendly cars are a danger because they don’t make enough noise. But now Lotus Engineering have come up with a way to add 'vroom' to a hybrid car.

The main concern with these quiet cars has been for the vision impaired, but children and distracted pedestrians, as well as cyclists, are also at risk. According to the Daily Mail “A study at the University of California found that a petrol or diesel car could be heard 36ft away but a Prius was not heard until it was 11ft from blindfolded volunteers.”

So to increase the noise Lotus have outfitted a Toyota Prius “with a waterproof speaker near the radiator that blares simulated yet realistic engine sounds to let pedestrians” (Wired).

England’s Neolithic artists had something of an abstract bent. While our continental artists were making human and animal representations 5,000-odd years ago British artists were carving convoluted lines and patterns into rocks, using other rocks as tools.

English Heritage, a government-funded body, has been cataloguing the carvings in the Northumberland region and has just released an online catalogue of them. It is also expanding this regional survey across the UK and hopes to add to the new carvings already discovered.

“There are many theories as to what rock art carvings mean,” says Kate Wilson, English Heritage’s inspector of ancient monuments (press release, Times news story). “They may have played a role in fire, feastings and offering activities, or been used as ‘signposts’, or to mark territory. They may have a spiritual significance.”

And according to Wilson, England’s rock-carvers may not be so different to their fellow artists after all. “The fact that these carved symbols developed in diverse and dispersed cultures across the world lend weight to arguments that these simple designs – and the urge to create them – are somehow hard-wired into the human psyche,” she says.

Any of you scuba divers? And any of you ever seen any insects down there? Nope, thought not. And why? Because of maths.

Insects manage to survive under water by forming a thin bubble around themselves to trap air and let them breathe. Mathematicians John Bush and Morris Flynn at the Massachusetts Institute of Technology have looked closely at all the factors that control the stability of the bubble and have done the sums to work out the limits on the insects’ sub-aquabatics. (paper and press release)

There’s a maximum depth that insects can dive to before the bubble pops, around 30 metres. But there’s also a minimum depth above which the bubble becomes unstable.

Even though these insects, like the water boatman, could dive deep deep down, they typically don’t bother – it’s dark, cold and there’s not much to eat – but plenty of things to eat them.

A famous 16th-century warship sank because its crew spoke a different language to its captain, says a researcher who has been looking at the crew’s skulls.

The Mary Rose was the flagship of Henry VIII’s navy before it sank, probably because water flooded in through open gun ports. The last words of its captain Admiral George Carew were of his crew: “I have the sort of knaves I cannot rule.”

Now Hugh Montgomery, a medical researcher at University College London, says he has found that many of the crew were Spanish, and may not have understood the order to close the gun ports. By looking at teeth from the shipwreck Montgomery and colleagues found their composition suggests they come from people who grew up in the Mediterranean.

“The analysis of the teeth suggests the men grew up in a warm climate, probably somewhere in southern Europe,” says Montgomery (Independent). “It’s also known that at this time Henry VIII was short of skilled soldiers and sailors and was trying to recruit mercenaries from the Continent.”

The claims will feature on a TV documentary next week.

The historic codebreaking centre that gave birth to the modern computer and provided vital assistance to the Allies in the Second World War is falling into ‘rack and ruin’, scores of computer scientists warned today. They say Bletchley Park needs cash, and fast.

In a letter to the London Times they write:

Although there has recently been some progress in generating income, without fundamental support Bletchley Park is still under threat, this time from the ravages of age and a lack of investment. Many of the huts where the codebreaking occurred are in a terrible state of disrepair.

My colleague Katharine Sanderson recently wrote about how poor regulation was hindering scientists’ use of unmanned aerial vehicles. Now Delft University of Technology in the Netherlands has a nice example of the sort of toys scientists may miss out on if legislation doesn’t get sorted out.

Dragonfly mimic DelFly Micro weighs just 3 grams and measures just 10 cm across but still manages to carry a camera. According to the university it can fly for three minutes at up to 5 metres a second.

“In a few years time, the new objective of the project, the DelFly NaNo (5 cm, 1 gram) will have been developed,” says the press release. “The Micro is an important intermediate step in this development process. A second objective for the future is for the DelFly to be able to fly entirely independently thanks to image recognition software.”

Maybe in a few years time those legislative problems will have been sorted out as well and we can start doing some science with these things.

The Eigenfactor website has some cool new tools.

For those not au currant with this metric, I will explain. The Eigenfactor, developed by a group out of the University of Washington led by Carl Bergstrom seeks to rank journals not just by impact but by value for money.

First, the influence of a journal is determined by a method that the group describes as more Google than Thompson ISI. Then this influence is multiplied by a measure of how many articles appear in each journal and how much each journal costs.

The result is a ranked list of which journals offer most influential content for the least money, and is one of a new crop of alternate impact factors (see our piece on SCImago Journal & Country Rank database) The fact that Nature is ranked as the top science journal by Eigenfactor in no way influences our interest in the tool…I swear.

Purdue University has announced that two allegations of research misconduct made against Rusi Taleyarkhan, a professor of nuclear engineering, have been upheld by an investigative committee. Ten other allegations were not upheld.

This is the latest chapter in a long saga, sparked by Taleyarkhan’s claim that he can produce tabletop fusion reactions in deuterated acetone by bombarding tiny bubbles in the liquid with sound waves. But the scientist has been dogged by controversy ever since.

According to the Purdue University press release, the report has been accepted by the U.S. Office of Naval Research, the funding agency that referred several misconduct allegations to Purdue.

Joseph L. Bennett, Purdue vice president for university relations, says that Taleyarkhan has 30 days to appeal. "Any decision on sanctions by the university based on the committee's conclusions will come after the appeal process," Bennett says.

California is battling its more than 300 wildfires with a little help from NASA.

Ikhana, NASA’s $20 million remote-controlled plane, is touring the fires from above to collect temperature data. The plane’s autonomous modular sensor works like a digital camera with filters to pick up visible light as well as thermal signals. It can detect temperatures from ½ to 1,000 degrees Fahrenheit.

The plane transmits data to scientists at NASA’s Ames Research Center in Silicon Valley, who overlay temperature information on maps from Google Earth and Microsoft Virtual Earth. The data reaches firefighting coordinates in minutes.

This image shows a portion of Monterey county last Tuesday afternoon; the yellow spots are fires, with red and purple showing burned areas. See more fire images from Ikhana and satellites at NASA. Another flight is scheduled for today [Tuesday].

California governor Arnold Schwarzenegger called the plane a “superstar,” “one of the most exciting new weapons in our firefighting arsenal.” (San Francisco Chronicle). Last week the drone identified a hotspot headed straight for the northern California town of Paradise, and that information allowed firefighters to head off the blaze and save the town.

Aircraft emissions are the current bête noir of the climate change world. So as one of the world’s biggest aersopace trade shows kicks off the plane people are busily showcasing their green credentials.

Although the actual percentage of carbon dioxide emissions made up by flights is small compared to some industries, it’s become a big issue.

At the Farnborough show, where aircraft manufacturers are hawking their wares, airlines observers are predicting a “damp” show. Recession, rumours of recession and increasing raw material costs (and non-raw material costs, too – clever composites aren’t getting cheaper…) mean a spiffy new aircraft is a hard sell. Reuters says this year’s event “may feel more like a wake” than previous shows, at which Boeing and Airbus have competed to show off massive orders for their aircraft.

Still, with high oil prices and increasing political pressure, there’s never been a better time to get a green-sheen on your planes. So that’s what some manufacturers are doing.

A giant airship could make it less environmentally damaging to undertake logging, mining and drilling in remote areas, according to the Boeing Corporation.

It says the boringly titled JHL-40, developed with Canadian company Skyhook, will be able to run 40-tonne loads into remote regions without the need to build roads and will “reduce the carbon footprint of the industrial projects it supports” (press release). This has an obvious attraction as road building is often cited as a devastating consequence of commercial activities in, for example, the Amazon.

“SkyHook is what we describe in our industry as a game-changer,” says Dave Koopersmith, a Boeing vice president (Wall Street Journal).

The airship will use just enough helium to carry its own weight, leaving the lift from its four helicopter rotors to deal with cargo. It could find use in the Arctic, forested regions, and in taking equipment to drilling rigs at sea.

Although it’s getting a lot of coverage, no one seems to be asking the obvious question: by making individual projects in remote regions easier don’t we encourage more of them?

It’s being claimed that a cherished Italian myth was shattered yesterday when the final blow was delivered to the origin story of Rome’s most famous statue, the Lupa Capitolina.

Experts have been chipping away for some time at claims that an iconic bronze showing a she-wolf suckling Romulus and Remus dates back to the 5th Century BC. The Romulus and Remus parts of the statue had already been dismissed as later works and doubts about the Lupa have been raised due to the method used to create it, which wasn’t thought to be known in the 5th century BC.

Yesterday Adriano La Regina, a former heritage official in Rome, said 20 tests had demonstrated that it was definitely a 13th century creation in an article in La Repubblica. La Regina says that the analysis was conducted last year, but the results were never published.

According to his article a battery of tests proves the 13th century date of the statue.

The Guardian and the Independent highlight his statement that radiocarbon tests were used in their coverage. Can you radiocarbon date bronze? It would seem unlikely to me but I’m open to correction in the comments. Anyway Rome e-magazine Eternally Cool notes that La Regina also says thermoluminescence tests were performed, which seems more feasible.

As previously noted on the Great Beyond and in the pages of Science though, the “lupa” that raised Romulus and Remus was probably not a wolf but a “very prosperous sex worker”.

General Motors is claiming it will soon have the largest rooftop solar power array in the world on top of one of its factories in Spain.

When work finishes in 2008 the roof of GM’s Zaragoza car factory will be covered in 186,000 square metres of solar panelling, generating up to 12 megawatts of power.

“The Zaragoza project demonstrates proof that GM is actively accelerating our efforts to be part of the solution to the environmental issues and challenges facing our world,” says Gary Cowger, one of the company’s vice presidents.

According to Reuters the solar panels will cut emissions by 6,700 tonnes per year. AFP says the plant produces 480,000 vehicles a year.

The EPA thinks the average family car puts out 5,000 kilograms of carbon dioxide a year. So at a very rough guess these panels will offset the emissions of 1,300 GM drivers of the 480,000 a year it provides cars for.

At least they’re trying though.

Scientists have given octopuses Rubik’s cubes in an attempt to determine if they have a favourite tentacle, or if they are octidextrous (a word that seems to have been invented specifically for this story).

According to a number of British papers around 25 octopuses at aquariums across Europe will be given toys and visitors will be asked to record which arm they are using to play with them, using a diagram showing the arms as R1, R2, R3, R4 and L1, L2, L3, L4.

“Uniquely, octopuses have more than half their nerves in their arms and have been shown to partially think with their arms,” says Claire Little, of the Weymouth Sea Life Centre (Independent). “Many animals have been shown to favour a certain arm so we will see if octopuses can be added to that list.”

According to Little, the findings could help make life in captivity more pleasant for these intelligent, (and occasionally shark eating), animals. “They are very susceptible to stress, so if they do have a favourite side to be fed on, it could reduce risk to them,” she says (Daily Telegraph, Daily Mail).

No one has suggested that any of the octopuses will actually solve the puzzle, but there’s a very slim chance they might. At the risk of re-igniting the now dormant ‘Echinoderms or Molluscs’ blog war, show us a starfish that can do that…

The plague of algae that has overwhelmed China’s Olympic sailing venue shows no sign of abating. Since first featuring on the Great Beyond on June 27 things seem to have got worse, if anything.

Now over 10,000 people are toiling away on the shore at Qingdao (Xinhua). .“We’re working nine-hour days. I’ve been here six days, and still more and more of it keeps coming," one of them told the BBC.

The BBC also says China “blames the sea for being too salty, the sun for being too hot”. One Chinese official notes that the algae isn’t all bad, saying “The Japanese eat it”.

“We have been working here five days with an average 14 working hours every day. About 3,200 tons of algae are cleared away each day. We are confident in cleaning up the sea before July 15,” says Liu Shuntang, a deputy director of the clean-up campaign (China Daily, with great photos).

Algae isn’t all they have to worry about though...

A huge warship deemed too-toxic to be broken up in India is to be dismantled in the UK.

The Clemenceau is a 238 metre long, 32,700 ton aircraft carrier, formerly the pride of the French Navy. She will be taken to Teesside and dismantled alongside the controversial US ‘ghost fleet’ by Able UK Limited (press release).

Given the furore around the asbestos-ridden US ships arrival off the coast of England a few years ago, it seems likely that some people are going to be up in arms about the already-controversial Clemenceau.

In a little over 50 days a land speed record may be broken on the salt flats of Utah. In an unusual twist though the Inspiration car will not attempt to beat the jet-powered Thrust SSC’s 1,200 km per hour.

This is a steam-powered record attempt.

Officially unveiled yesterday after years of development, Inspiration will use liquefied petroleum gas to turn a tonne of water into steam, hopefully powering it up to 280 km per hour. Currently the record stands at 230 kmph.

The Guardian thinks it’s a ‘flying kettle’. Popular Mechanics says it’s ‘Jules-Verne-meets-Batmobile’. And of course, there is an eco-aspect to this. The people behind the project say:

With growing public concern about the buildup of toxic and smog producing gasses produced by internal combustion engines, a trend is emerging toward more ecologically friendly technologies for such sectors as public and private transportation. ...

With these issues in mind, the decision was made to create a vehicle that would set a new land speed record, incorporating new technologies to bring excitement to the arena of ecologically friendly technologies. In the process of setting the land speed record it is hoped that additional attention to green vehicle technologies will be generated.

“I’m not saying we're all going to be driving steam cars but the technology could have other uses,” says engineer Matt Candy (Guardian).

A student in America has worked out how to turn his face into a remote control.

PhD student Jacob Whitehill, of UC San Diego, used facial recognition technology to monitor the expressions of test subjects watching video lectures. By detecting confusion, he believes, lectures can be slowed or even replayed over difficult sections.

“If I am a student dealing with a robot teacher and I am completely puzzled and yet the robot keeps presenting new material, that's not going to be very useful to me,” says Whitehill (press release). “If, instead, the robot stops and says, ‘Oh, maybe you’re confused,’ and I say, ‘Yes, thank you for stopping,’ that’s really good.”

In a paper to presented at an upcoming conference he reports that his system predicts subjects' self-reported difficulty scores correctly 42% of the time. It’s not quite so good at preferred viewing speed, with only 29% accuracy on this.

Only eight people were involved in the pilot study, where Whitehill confirmed results from previous research showing that people blink less during difficult parts of the lecture. So there’s a lot of work left to do, but Whitehill believes his system could be trained to react to individual users’ expressions.

Are Californian students really too lazy to use a remote? Any readers from that demographic are welcome to comment on this question below.

Rock music is bad for art, according to Russian researchers.

Mikhail Piotrovsky, director of the State Hermitage Museum in St Petersburg, says concerts in the nearby Winter Square have damaged the sculptures housed in his museum, and possibly the building itself too.

According to the Independent, Piotrovsky was so concerned that he reached an agreement with the Rolling Stones to keep the noise down when they played in the square last year. The paper says he was “distressed” when Paul McCartney’s 2004 concert shook the museum’s windows (and maybe also by the fact he played some Wings numbers, but that’s my speculation).

According to a currently unpublished three-year study from the museum, every 10 concerts above 82 decibels “add an extra year” to the life of the work, say both the Daily Telegraph and the Independent (in suspiciously similar sentences – below the fold). In terms of artificial aging, rather than expanding lifetime, presumably.

Rock concerts can easily top 100 decibels and many places that host them have sculptures: the Independent cites Somerset House and Knebworth in the UK. Before we once again blame the evils of the world on rock music though, it’s worth noting a performance off Wagner can top 90 decibels.

If you thought watching snooker on a black and white TV was hard, imagine what it’s like for a doctor trying to spot cancer in the brain. So it’s a great step forward that researchers have worked out how to make MRI scans in colour.

At the moment the medical scans come only in black and white and use magnetic ‘contrast agents’ to improve the image. Obviously you can colour them in afterward with the hi-tech equivalent of a box of crayons but this isn’t hugely helpful.

However, in this week’s Nature Gary Zabow and colleagues in the US detail new contrast agents that can be tuned to produce different signals on an MRI scan by changing their shape. These agents could also be modified to ‘tag’ particular cells or tissues (research paper, press release).

Forgive us for only just having noticed this but the Encyclopaedia Britannica has done something of a U-turn.

Having railed against user input, they’re now coming over all Wiki on us. As Silicon Valley’s The Mercury News notes, “Soon you, your family, friends - and even that nut case down the street - can publish in the venerable Encyclopedia Britannica.”

“By inviting a larger range of people to contribute and collaborate, we can produce more coverage,” says Britannica spokesman Tom Panelas.

According to Wired there will now be three type of content, entries from Britannic experts, user generated content, and the official encyclopaedia which will use elements of both.

In 2005 a Nature investigation found Wikipedia surprisingly close to Britannica in terms of the accuracy of its science entries.

Having recently come across Wordle, a “toy for generating ‘word clouds’ from text”, I wondered what would happen if you ran scientific things through it.

This is what happens. [Hat tip: Good Morning Silicon Valley.]

UPDATE: The first edition Copernicus went for $2.2 million. Dalton’s book went for a bargain $18,750.

If you want to grab yourself a piece of science history you better get to New York on the double. Some of the most important books ever published are coming up for auction today.

Christie’s in New York is selling off the Richard Green library of what is, with amazing understatement, called ‘Important Scientific Books’. Described by the auction house as ‘a physician and amateur astronomer’, Green started collecting scientific books in the 70s. Boy did he build up a good collection (press release pdf).

The star of the show is a first edition of Copernicus’s De revolutionibus, described by Christie’s as “arguably the finest copy in private hands”. With no hyperbole, this can be described as one of the most important books ever published, and the finest exploration ever of the phrase “the world doesn’t revolve around you, you know”.

The NY Times notes in a June 10 article:

Its cover is dented and stained. The pages are warped. You could easily imagine that this book had sat out half a dozen revolutions hidden in various dank basements in Europe.

In fact this book, published in 1543, was the revolution. It was here that the Polish astronomer laid out his theory that the Earth and other planets go around the Sun, contravening a millennium of church dogma that the Earth was the center of the universe and launching a frenzy of free thought and scientific inquiry.

If you’ve got between $900,000 and $1,200,000 it could be yours. If that’s a bit rich for you a second edition is estimated to go for between $60,000 and $80,000.

NASA is a step closer to the spacesuits astronauts will wear on the moon in 2020. On Friday it announced that Houston-based company Oceaneering International would be making its suits.

The contract, worth up to $745 million, is for two configurations of the space suit (press release, news coverage).

“Configuration One will support dynamic events such as launch and landing operations; contingency intra-vehicular activity (IVA) during critical mission events; off-nominal events such as loss of pressurization of the Orion crew compartment; and microgravity EVAs for contingency operations,” says NASA. “... While preparing to walk on the moon, the astronauts will construct Configuration Two by replacing elements of Configuration One with elements specialized for surface operations.”

As The Hartford Courant notes, this means NASA is “abandoning Hamilton Sundstrand as its spacesuit supplier after more than 40 years”. Hamilton is based in Hartford.

“We were very deeply hurt that we did not get the contract,” the paper quotes Donald Rethke, a Hamilton consultant, as saying. “To me, it’s the end of an era.”

The world’s fashion writers have yet to comment on the suits but we think configuration one is the look to go for: pleasingly retro, aggressively functional and flattering looks make it the must-have this season. By contrast configuration two ticks all the fashion no-no boxes: bulky, makes even super-fit astronauts look fat, has a terrible rucksack accessory and is a truly awful blue colour.

It seems internet fraudsters have tired of pretending to be African despots and Spanish lottery syndicates. Now they’re pretending to be academics.

Into various Nature inboxes has popped the following message:

I am Dr. Robert Pasteiner, the head of department of clinical pharmacology and director of research, at the University of London. I write to solicit your assistance in a project of mutual benefit.

In February 2003, a research grant of (US$58.5 Million) was given to my department, with me, leading a team of other clinical pharmacologists, by the pharmaceutical society of United Kingdom, to conduct a research on Vector-borne diseases in Scotland and Ireland. The research has since been concluded (specifically in May 2006) we only spent US$36.2 Million, leaving a total balance of US$22.3 Million.

An under-spend of 38% on a government research project? Our hard-nosed reporter smells a rat on this one. Read on for our exclusive interview with Dr Pasteiner...

Swiss inventors have unveiled an amazing jumping robot, which they claim could explore inaccessible areas on other planets or help rescue missions here on Earth. Inspired by the grasshopper, the 7 gram robot can jump 27 times its body size, 1.4 meters (Daily Telegraph, MSNBC).

“This biomimetic form of jumping is unique because it allows micro-robots to travel over many types of rough terrain where no other walking or wheeled robot could go,” says Dario Floreano, of the Ecole Polytechnique Federale De Lausanne (press release). “These tiny jumping robots could be fitted with solar cells to recharge between jumps and deployed in swarms for extended exploration of remote areas on Earth or on other planets.”

A tiny battery powers an equally tiny motor that tensions springs. These then power the robot’s jumps. The robot, which appears not to be named at the moment, is being presented at the International Conference on Robotics and Automation today in Pasadena.

More highlights from the conference below the fold.
