Life = matter + information. Or does it?

“We are points of order in a disordered universe. This is an expression of how we feel about being ruled by physics in all our emotions and reactions. It’s how we interpret, describe and live our lives within this system.”

Artist or scientist? These are the words of curator Caroline Wiseman, whose brainchild “Alive in the Universe” found a home at the world’s longest standing contemporary art fair in Venice yesterday. It is a month-long exhibition that seeks to interpret what life is, and rather than reduce it to an equation, surround the viewer with an experience of what that means.

Opening the show is Syrian-born Issam Kourbaj. His three-piece installation is made up of a video of burnt matches, 98 boats made of recycled material and an IV drip. It juxtaposes the energies of fire and water, the flow of death and life, the struggle of a people between the two and the flow of time with the flow of migrants.

“Are we aware of the threads of our lives? I am putting the viewer in a place where many senses are being revisited. Each material sends new signals of information.”

Collaborating alongside him is Ruth Padel, a British poet whose book The Mara Crossing (2012) elucidates detailed comparisons in the way life organizes itself. Whether in cell biology, ornithology or human history, it is with the passage of migration that life begins, she says.

“There are two main reasons cells migrate in our bodies: One to create a new life, and two to defend the body –if we get a new cut the corpuscles and others rush to the site of trauma,” she explains. There’s an interesting parallel to be drawn with people migrating – a vigorous society is constantly replenished by the outside. Human civilization began with migration out of Africa. The first cell arrived on the planet, whether from the sea or outer space, and it colonized other places. The first great land migrants were trees. DNA from the oldest oak trees in Britain shows they came from the Spanish peninsula.”

Living things migrate because life becomes impossible or there’s a desire to make a better life. Birds in or near the Arctic get too cold and fly south. When the south becomes too crowded and they need to breed they return to the Arctic where there are lots of insects –  a protein-rich diet for their offspring. It’s a bit heartbreaking but if you overlay the maps of bird migration routes and human migration routes across the Mediterranean, it’s the same. They take the passages where water is smallest – the straits of Gibraltar, or through Sicily, Malta.

Venice, Ruth says, represents the wasp waist of information flow between north and south in history. Both she and Kourbaj will find new resonance for their work in the interconnectivity of the space around them. “My interest will be in the relationship of my work to the water, and to the tourist boats and the gondola boats,” says Kourbaj, “in scale and in meaning, and in contradictions, they will have a new charge.”

For Wiseman, this too is interesting: “What I am trying to do through creativity is put order into things. The more I thought about what this order could be, the more I found that it is the life force, it is evolution.”

Life seems coupled to flow, movement, change, transformation: information in whatever form – the passage of energy, the replication of DNA within biological cells, to animal migrations and the organization of human societies.

University of Tübingen archaeologists unearthed 93 clay tablets adorned with cuneiform pictograms, an early Sumerian writing system, in the Kurdish region of northern Iraq. The archive dates back to 1250 BCE.

The tablets were dug out of Bassetki, an ancient Bronze-age site which was only discovered in 2013, and whose location lay along busy trade routes from Mesopotamia to Anatolia and Syria.

“Bassetki was of key significance on important trade routes,” Peter Pfälzner, lead archaeologist, says of the discovery. “Our finds provide evidence that this early urban center in northern Mesopotamia was settled almost continuously from approximately 3000 to 600 BCE.”

A big chunk of tablets had been deposited in a ceramic pot, probably used for storage, in a room inside a destroyed Assyrian building.

“The vessels may have been hidden this way shortly after the surrounding building was destroyed. Perhaps the information inside it was meant to be protected and preserved for posterity,” says Pfälzner.

A fragment of the clay tablet contains mentions of a temple to the ancient goddess Gula. However, the scientists believe it might be too early to rule whether they’re looking at legal, or religious text.

The researchers will begin translating the text in Germany, which they say will be challenging, time-consuming and intense since many of the tablets are either unbaked or badly worn.

Visual experiments straddling art and science

Digital artist and director Markos Kay pioneers at visualising the unvisualisable.

“Art and science are drivers of cultures,” says Kay, who visited the Middle East for the first time last month to exhibit a new film called ‘Quantum Fluctuations: Experiments in Flux’ at the Imagine Science Film Festival in Abu Dhabi. “I want to challenge our ideas of how our knowledge of reality is formed.”

He is perhaps best known for a generative short called The Flow (2011), which was featured in an episode of the TV hit series Breaking Bad.

The Flow takes its audience inside a proton, with the aid of simulation software and algorithms, to see a dramatically-visualised interplay of quarks and electrons, resulting in nuclei and atoms. “I was really frustrated that nobody is trying to visualise all this in a more accurate way, so I tried to make my own film. I wanted to show people how complex this stuff is,” he says.

Kay’s work explores and abstracts the complex worlds of molecular biology and particle physics, be it through presenting a different way of observing cells or using the visual language of a microscope to give life to an organic process. “The desire of an artist to find ways to interpret and observe the world is similar to a scientist’s,” he says of his own experiments.

His films are usually filled with detail and movement, and often feature scores of orchestral sounds or a generative, organic soundscape created by algorithm-based software.

His new film, ‘Quantum Fluctuations’, for instance, meditates on the transient nature of the quantum world which, he says, is impossible to observe directly. The film re-imagines the complex interactions of elementary particles as they collide inside the Large Hadron Collider at CERN –– and it’s all presented against a musical backdrop that is designed by Kay himself. Through striking computer-generated imagery, we can see interactions that occur in the background of a collision; for example, particle showers that erupt from proton beams colliding, giving birth to composite particles that eventually decay.

“Since the time of Heisenberg, it’s been almost impossible to visualise these events and simulations. It felt like a challenge,” Kay says. The film was produced by experimental design studio Epoche.io and will be part of an art and science documentary called “Sense of beauty” that focuses on CERN’s particle physics and that will be released later this year.

His latest project Humans After all, in collaboration with photographer Jan Kriwol depicts people in the context of everyday life through their circulatory systems. The project that showcases its subjects – humans stripped down to blood vessels and neural circuits – in an urban setting is meant to highlight the fragility and vitality of the human body.

“Through my work, I try to create immersive environments so that people can feel they’re entering a distant world.”

Does language limit scientific expression?

Scientific papers

This is a guest blogpost by Aya Nader.

More evidence is confirming that the choice of language used in scientific literature can influence access to it, and how visible its authors are – including in the Arab world.

Language can limit the transfer of knowledge for one, concludes a study that looked into the prevalence of scientific literature written in local languages. The study, published in PLOS Biology, confirmed some sentiments that many researchers across the Arab world already have.

Over one third of conservation-related scientific documents are written in non-English languages, and a large proportion of local researchers interviewed in the study identified languages as a barrier to accessing knowledge. “I was expecting to see these results, as that was the primary motivation to conduct this work,” says Tatsuya Amano, corresponding author.

Amano says that gaps in information are formed when local scientists either do not get exposed or turn away from publishing in their original language. What surprised the researcher was that over one third of non-English literature reviewed in the study provided neither the title nor the abstract in English, so it’s essentially “invisible to international communities”.

The study might explain why Arab scientists are not as visible, in terms of science research, to international peers, he opines.

“Perhaps only 25% of the global population has some understanding of English and we cannot limit science to just a fraction of the world,” says Steve Griffiths, vice president for research at Masdar Institute of Science and Technology. According to him, having scientific knowledge being somewhat confined to the English language can present a problem when collecting scientific data or disseminating information.

“While language is probably not the driving force behind the lag in scientific visibility of Arab scientists, it certainly can hinder progress,” Griffiths says. Different factors could be causing the lag, he says, which include that the region has only been recently making strides in establishing top-tier research universities and institutes. As well, regional equivalents of supportive bodies like the US National Science Foundation or the US National Institutes of Health are absent.

One of the barriers could be the language itself. A few argue that Arabic, because of the way it’s structured, cannot be adopted as a language of science. “I personally am fluent in English and have studied Arabic for some time and clearly see the translation challenges for technical information,” says Griffiths.

On one hand, English is the universal language of science. On the other, having science available in the local language can enlighten field practitioners and local policy makers.

“The availability of scientific information in relevant non-English languages is a key to the use of science in policy making in countries where English is not widely spoken,” comments Amano. It’s one factor contributing to the divide between science and public policy. “I imagine that extremely busy policy makers would prefer just using easily-accessible information in their own languages, instead of trying to understand English-written papers.”

Poor English skills are observed in many MENA countries and particularly within the government sectors, which limits the uptake of scientific information, Griffiths highlights.

In order to compile non-English scientific knowledge effectively and enhance publishing of new and existing knowledge that is otherwise available only in English, Griffiths suggests launching regional initiatives modeled after the MIT Global System for Sustainable Development. The networking hub, specialized in sustainable development, was created to give researchers that speak English, Arabic, Chinese and Spanish seamless access to its science content.

Another approach is to encourage individual researchers to translate their work, or provide lay summaries of their work in different languages.

There’s also hope in artificial intelligence (AI) for natural language processing (NLP). “Major industry players like Google, Microsoft, Amazon and IBM are deeply engaged in AI NLP for commercial reasons, and over time the outcomes will benefit the scientific community,” Griffiths suggests.

Longer lasting batteries

This is a guest blogpost by Aya Nader.

Using two dimensional oxide anodes with a controlled number of atomic layers is an effective way to prolong the cycle life of Na (sodium) ion batteries, scientists from Saudi Arabia have revealed in a new research. The advancement carries great potential for grid storage.

Batteries normally have two electrodes: anode and cathode. Anodes can be manufactured from different materials, including oxides, sulfides, and phosphides. Usually, oxide anodes such as tin monoxide (SnO) go through massive volume change and degrade significantly after use, seriously shortening the life cycle of a sodium ion battery. Typically, researchers mixed the oxide anodes with carbon-based materials such as graphene to mitigate this large volume change.

“However, the new approach stacks few atomic layers of two dimensional SnO anodes to suppress this volume change, making batteries that last more than 1000 cycles,” explains Husam N. Alshareef, principal investigator of the study and professor of functional nanomaterials and devices at King Abdullah University of Science and Technology (KAUST), Saudi Arabia.

They used two dimensional materials made up of sheets of atoms, or atomic layers, stacked on top of each other. The thinnest SnO nanosheet anodes (two to six SnO monolayers) exhibited the best performance according to their study, published in the journal Nano Letters. As the average number of atomic layers in the anode sheets increased (beyond 10), the battery performance degraded proportionally and remarkably, the study found.

Now, the researchers are trying to combine the SnO anodes with suitable cathode materials to create full cell sodium ion batteries. The idea is to use these batteries to power small devices, such as phones and other electronic devices, and test their cycling performance in more realistic conditions.

In addition, the scientists plan to try charging up the batteries using solar power. Practically, sodium ion batteries are candidates to replace lithium ion batteries, especially in stationary storage applications, as sodium is cheaper and more available than lithium.

“Our progress using SnO anodes has resulted in stable sodium ion batteries that offer competitive capacity for grid scale applications,” says Fan Zhang, PhD researcher and lead author of the study. “This is exciting because it means a more effective storage solution has been identified for grid storage applications.”

The United Arab Emirates first ever nanosatellite, Nayif-1, was launched a few hours earlier – it was among 104 satellites propelled into outer space on board the PSLV-C37 rocket from Satish Dhawan Space Centre in India.

It’s the Gulf country’s first CubeSat mission led by seven Emirati engineering students from the American University of Sharjah, in collaboration with the Mohammad bin Rashid Space Centre. The first signal was heard in North America during the night hours (local time), roughly 18 minutes into the launch.

The AUS team will monitor the satellite’s direction and control until it’s switched to autonomous mode.

An educational CubeSat project, Nayif-1 will send and receive messages that will be picked up by amateur radio frequencies; it’s programmed to transfer messages in Arabic, also a first.

A CubeSat is a type of miniaturized satellite for space research that is made up of small cubic units, with a mass that typically doesn’t exceed 1.33 kilograms per unit. They often use commercial off-the-shelf components for their electronics and structure.

According to its makers, the Emirati CubeSat also holds an active control system board that is being launched in space for the first time.

Biosensor zeroes in on dangerous bacteria

Staphylococcus or Staph aureus is a type of infectious bacteria that commonly causes skin and respiratory infections in addition to food poisoning. In some cases, it can lead to life-threatening diseases such as pneumonia, and brain, bone or heart infections. As well, it’s a common hospital acquired infection.

Now, a team of scientists from Saudi Arabia and Jordan have developed a point-of-care diagnostic test as effective in food samples as it is in clinical samples to detect the bacteria. It’s cheap, instrument-free, and takes less than a minute, according to lead researcher Mohammed Zourob, professor of chemistry at Alfaisal University in Saudi Arabia.

The researcher and his colleagues tested the biosensor in food and clinical isolates from a hospital but instead of targeting bacterial cells, as traditional sensors would, they targeted poteases enzymes released by the cells or expressed on the cells’ surface. The former’s sensitivity is too poor to detect infectious dozes of most bacteria, according to Zourob, unlike the latter method, invented by Zourob et al.

The probe itself is made up of a specific peptide sequence, cleaved by Staph aureus proteases, and sandwiched between magnetic nanobeads and gold surface on top of a paper support.

Another perk to the test, according to its developer, is that it does not require special training to use, so it can be easily administered by food inspectors and hospital nurses.

Zourob and his colleagues say they are now establishing a spin off in order to commercialize this new technology.

In its third edition in Abu Dhabi, Imagine Science Film Festival, running from 2 to 4 March, 2017, is dedicated to light, reflecting on it through a multitude of films spanning documentary, fiction and experimental genres.

The film festival, which contemplates the intersection between science and art and which takes place at the Arts Centre in New York University Abu Dhabi (NYUAD), chooses a theme for its productions every year, and creates a conversation around it through talks, workshops, performances, and screenings of both local and international films.

In the past, the festival has collaborated with Zayed University, Petroleum Institute, Masdar in addition to NYUAD’s Arts Center in a keen effort to encourage local filmmakers to particpate in programming and filmmaking.

This year, the festival explores another fundemntal of life: light, and “how in multiple ways it has shaped how we see and understand the world providing us new insights, methods and understandings of how investigate our surroundings, and their scientific and artistic subtexts,” according to NYUAD professor and festival founder Alexis Gambis.

The festival is still accepting film submissions until December 5, 2016; works that, in the words of the festival founders, give viewers “a deep look into the natural, technological, and theoretical worlds, from the smallest molecule to the furthest reaches of space and everything in between”.

Many of the artists showcased are usually in attendance at the festival, which, in 2017, is expected to include panels on how we process and make sense of an overflow of media and information, a career talk with scientists, artists and filmmakers and how they navigate worlds that incorporate scientific and artistic dimensions, in addition to a retrospective of Larissa Sansour’s Space Triology: Nation Estate, Space Exodus, and In the Future They Ate from the Finest Porcelain (the latter featured in the second edition of Imagine Science).

Imagine Science will also exibit a revisited animation about Quantum mechanisms where data visualizations (inspired by CERN) will be projected on sand from Liwa desert.

According to Gambis, in 2017, the featured films will move from traditional documentaries to regional science fictions, experimental studies, and narratives inspired by essential science issues.

“We’re seeking new science films of all styles and subjects. Possible themes include technological shifts, neurological and cognitive functions from vision processing to memory and even dream, and the ecological and sociological studies of the Gulf and MENA landscape,” he elaborates.

To know more about the festival, how it began and what its creators have in store for it, listen to the latest edition of Nature Middle East‘s monthly podcast where this editor talks to Gambis about his brainchild and how it rose to prominence over the years.

Saudi Arabia opens a cutting-edge laser facility; unique in the region

The Attosecond Science Laboratory at King Saud University (KSU) in Riyadh – opening only this week – is the first of its kind in the region, hosting an “attosecond laser,” an important tool in atomic physics and molecular sciences, reports Nature magazine.

The kingdom’s largest and oldest universities has collaborated with the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany, which hosts its own attosecond laser, and the Ludwig Maximilian University of Munich. “It is very exciting that the frontier of attosecond science is now having its outpost in the Gulf state,” Olga Smirnova, an atomic physicist at the Max Born Institute in Berlin, tells Nature.

Attosecond lasers generate ultrashort pulses of light, lasting just a few billionths of a billionth of a second, that can image otherwise invisible electrons as they move similarly fast within atoms. They were first reported in 2001 by a team led by the MPQ’s Ferenc Krausz, who heads the Attosecond Science Lab, and they have since expanded from the realm of atomic physics to the that of molecular science, including condensed-matter systems and molecular biology.

Read more on the new state-of-the-art facility and the collaborative efforts with Western scientists to make it happen here.

2014 Year in Review: Nature Middle East highlights

In retrospect, 2014 was a mixed bag for the region – with some significant research produced on one hand, but on the other, in some countries, education, health and sectors in academia received some hard blows as a result of conflict and war.

In Syria for instance, the risk of infectious diseases is at its highest, warned a study published in PLOS Pathogens. The crisis was branded “a public health emergency of global concern” – with vaccine-preventable diseases not only reappearing in Syria but spreading to other countries with the outpouring of refugees, such as Lebanon and Iraq, which itself is reeling from years of damage to infrastructure and a myriad of health disasters.

Outbreaks of polio were reported – years after the Middle East was deemed “clean” – with WHO, UNICEF and ministries of health rushing to contain it. But even the largest vaccination campaign in the region’s history couldn’t reach its target as hundreds of thousands of children remain vaccinated, especially with access to hot zones barred.

Measles and rubella continue to be a burden in Syria, and in one instance, the vaccine killed instead of saved. At least 15 children died last September after being administered vaccines that were wrongly formulated, probably turning families away from seeking it and leaving many children unprotected.

Also in Syria, the lack of medical personnel is forcing untrained volunteers to tend to the injured and sick in hospitals.

Adding insult to injury, a study in The Lancet this year says that civilians aren’t even a priority for hospitals in a country like Syria, torn by civil wars. Fighters take up the majority of the available spots. In other hospitals, doctors risk their lives when they treat patients from the “opposite camps.”

In Iraq, the Islamic State (IS) is spreading its own brand of terror – taking over big universities and closing them down, including the historic University of Mosul. The education hubs are now used as makeshift camps for the militants. An independent Baghdad-based research tells Nature Middle East that soon conducting quality research in Iraq will be impossible. Skilled professors are already migrating in droves, in fear for their lives. “Many won’t come back even if the conflict ends,” says the researcher.

The International Center for Agricultural Research in the Dry Areas (ICARDA) conservation agriculture project that helps local farmers increase food production has been in jeopardy in Iraq since IS takeover. Insecurity, fuel shortages and lack of necessary equipment is breaking them, they decry.

Nearby, an estimated 3,900 schools in Syria had been destroyed or closed down during the first two years of the war. By April 2013, “22% of the country’s 22,000 schools [were] rendered unusable,” according to UNICEF.

The year 2014 also saw a comeback by Middle East respiratory syndrome coronavirus (MERS-CoV), which killed and inflected hundreds worldwide across 19 countries, with most of the infections concentrated in Saudi Arabia, where the virus was first discovered.

Nature Middle East was lucky to exclusively speak to the Egyptian virologist who first identified the virus, telling us the story of “patient zero” who died from an acute respiratory condition which was later revealed to be MERS itself. The mystery of MERS’ transmission was not lifted in 2014, but at least some countries are speeding up research into antiviral drugs that could contain it, or hinder its spread. Still, the fact remains, there are no anti-MERS drugs on the market so far.

In fact, overall things have been going south – health wise – for many in the region; not counting conflict victims and health complications due to war. A silent yet lethal predator, diabetes, has been preying upon the masses – with 35 million diagnosed with type 2 diabetes in the region.

Essentially, we have the  highest prevalence level of  in the world – with 1 in every 10 people living with it. Type 2 is tied to lifestyle, while type 1 has to do with genetics, autoimmune and environmental factors – and the incidence of the latter is rising sharply.

The highest rate of type 1 diabetes is in Saudi Arabia, with a shocking incidence of 14,900 children living with the disease, approximately a quarter of those in the Middle East and North Africa.

But in slightly better news, the region has managed (so far) to evade Ebola, which transmits through direct contact with bodily fluids and gains access to the body through skin abrasions and mucous membranes. The virus, however, has culled many in the central parts of Africa, and has fatality rates of up to 90%.

In terms of research, the region has been more prolific. Nature Middle East‘s chief editor Mohammed Yahia writes about the freshly released Nature Index, which was released in November and tracks where high impact research is being conducted around the world, and it shows many positive trends in the region – with Saudi Arabia leading with 358 papers, followed by Egypt.

Examples of prominent regional research includes one showing how Neolithic North Africans began exploiting cereal crops at least 500 years earlier than previously thought, published in PLOS ONE. The earliest evidence of cereal crop domestication in North Africa comes from the Fayum area of middle Egypt, and dates back to around 4350 BC.

In Lebanon, researchers from the American University of Beirut identified an algae species that can be a possible source of superfood and cheap renewable energy. In neighboring Syria, it turns out, two areas have the world’s highest concentration of wild-growing crops. The potential for these crops, distantly related to today’s agriculturally produced crops, lies in their gene pool, and adaptability – something that can provide breeders with genes that could enhance crop resistance to stresses such as climate change, pests, and disease.

Other breakthroughs include: In Sudan, a stunning discovery of a 3,000-year-old skeleton with metastatic carcinoma challenges the notion that cancer is a modern disease, opening new horizons for specialists to research cancer’s etiology and evolution. The ancient Nubian is probably the first cancer victim in archaeological record. As well, dinosaurs lived in Saudi Arabia, it seems. Fossilized remains identify specific dinosaur species from millions of years ago in the Arabian Peninsula when the area was covered by lush vegetation.

That being said, this year was not easy on the region, and infrastructures that provide the backbone of scientific endeavors have bore the brunt of political upheavals. In terms of progress – if we choose to compare notes with developed countries – we’re only barely inching forward.

Independent or university-backed research in the Arab world, collaborations with world-class institutions notwithstanding, is not enough to help Arab-affiliated researchers catch up with an incredibly prolific West. Governments must step in, opines Nobel laureate Ahmed Zewail and the academic president of Zewail City of Science and Technology Sherif Sedky.

“Renaissance in the Arab world will not be possible without genuine government recognition of the critical role of science in development and policies providing commensurate funding for basic research and reform of rigid bureaucracy which thwarts progress,” the experts say.

And considering it’s politics that seems to be setting the region back, Zewail and Sedky’s words ring true.

It is essentially a tug of war – between competent scientists and experts who’re aspiring to propel this region into the future, and governments staggering to make ends meet for their people, giving science a cold shoulder in the process. The next year may not tell us who wins, but it may very well give us indications – through statistics above all – of who is tugging harder.
