The Ardi drama continues

ardi-ape.jpg

When the fossil remains of Ardipithecus ramidus were studied and published in Science in October 2009, they sent ripples around the world. Ardi was the closest we had come to the common ancestor of humans and chimpanzees.

However, the ripples were particularly violent in the Arab world when Al-Jazeera Arabic reported the findings under the blatant headline of “Ardi proves Darwin wrong”.

This ended up in tons of discussions that I had been involved in, ranging from how science is taught in the Arab world to how evolution is perceived to the faults and mistakes of science journalism in the region. Al-Jazeera never retracted nor apologised for the misleading story. In fact, that particular example became a cornerstone of discussions of what can go wrong in science coverage in the Arab world.

Now, there is a good chance that Ardi may not have been a direct human ancestor after all. A new paper published in Nature last week suggests that Ardi may not have a direct ancestor of humans, but a direct ancestor of the African ape.

“We could actually place Ardipithecus in a lineage that’s unrelated to humans,” Terry Harrison, of the Center for the Study of Human Origins at New York University and co-author of the paper, said in a podcast with Nature.

Researchers are explaining this as a case of convergent evolution. This is when different species might evolve similar solutions to certain environmental stressors and be survive through natural selection. These species may not even be closely related, but could be mistaken to be so due to the similarities seen between them. These similarities might be in the shape and size of teeth for example, or certain skeletal changes.

Now Ardi may or may not have been a direct ancestor of humans. It is very tricky to be able to work that out because it happened millions of years ago, and because we don’t know what that common ancestor between huamsn and chimpanzees really looked like (of course we have many theories, but no concrete facts). But this is really beside the issue. In time, I’m sure we’ll have a more definite answer in the near future. It is the very nature of science to keep correcting itself and, by doing so, evolve in its own way.

What worries me now is if a news organization (Al Jazeera or else) picks up this story and puts it under a headline that reads something like “another nail in the coffin of Darwin’s theory” or something equally ridiculous. Coverage of evolution stories remains one of the poorest in the Arab world’s ever improving science reporting. This is a combination of religion bias, misinformation, and translation problem (this is in personal opinion, feel free to prove me wrong ofcourse).

I will be keeping a close eye on if this story is picked in the Arab world, how it is picked, and where exactly the journalist working on it took it. Please do let me know if you run into any Arab-based media outlets reporting on this as well.

One small step…in the desert of United Arab Emirates

NASA’s annual Spaceward Bound programme into the deserts of Earth in search of extreme life is soon to set-off for the far reaches of the United Arab Emirates.

The seven-day expedition to AL Gharbfield brings five NASA scientists, five UAE scientists, a select group of 20 local schoolteachers and 50 pupils together. Their mission — to inspire the next generation of space explorers and encourage children to choose science studies.

The teachers get to rub shoulders with top planetary scientists. This experience, it is hoped, will help the teachers to develop curriculum related to human exploration of remote and extreme environments. While the children get hands-on activities that enhance critical thinking and a chance to explore scientifically interesting but remote and extreme environments.

According to NASA, the trip entails

• Logistics and transportation

• Energy and life support

• Human factors

• Exploration and EVA activities

• Moon/Mars science and analog concepts and theory

The team will analyse salts in the desert groundwater, and set up year-round data loggers to monitor rain, fog and the growth of tough cyanobacteria found in the harsh climes of the desert.

“This microbiology shows the beginning of life, how life got started,” Asma al Ketbi, the head of the Emirates Geographic Society and a geography professor at UAE University, told the UAE daily The National. "That could be useful for understanding extreme environments on other planets.”

“The idea is that when comparing samples from the UAE to samples from other parts of the world and with samples eventually taken from Mars, similarities of the organisms might be found,” AbdulMajeed al Khajah, a UAE University medical microbiologist on the team told UAE Interact.

A scientist president?

Zewail talking to young scientists.jpgThough almost all Egyptians rejoiced at the news that Hosni Mubarak was stepping down as president, it quickly dawned on them that 30 years under his autocratic regime have wiped out any serious contenders to the presidency.

As people settle down after the excitement of the revolution, they are slowly studying the options on the table. While no one has announced his or her intention to run for the presidency just yet, there are several names already floating around.

Ahmed Zewail, who won the Nobel Prize for Chemistry in 1999, is one of the names that quickly rose as a favourite among many Egyptians. The public see him as someone they can trust, untainted by corruption in Egypt. Educated young people view him as a cultured and intelligent individual who can tackle Egypt’s most pressing problems of education reform.

Zewail has previously denied he was interested in running for the presidency, insisting he has come back “to serve Egypt as a scientist.” However, yesterday he sent out his strongest message yet that he may be changing his mind soon.

“My national responsibility towards our country in these dire times and thousands of letters from Egyptians from within the country and abroad made me reconsider and think about running for the presidency,” said Zewail during a meeting he held with young Egyptian researchers arranged by the science-focused NGO Age of Science .

Zewail went on to stress that the next Egyptian president must be solicitous about science since. “Overhauling science research will have a direct effect on developing the economy and solving all the major problems that Egypt faces within the next few years.”

The next president cannot only be concerned with politics as was the case in the past, he added. “Let us try science for a change.”

Several of the young researchers, curious about the future of science in their country, eagerly asked Zewail how scientific research could be fixed. Smiling, he told them that we can’t go on “patching” scientific research and education, but need a new, modern vision for a completely new system to develop universities and to support professors and researchers through their work.

While this piece of news got many people excited, others were hesitant about Zewail becoming president.

“You need very strong political skills to be a president, especially at these dangerous times in Egypt. He’s a scientist, not a politician,” told me Ahmed Fathy, a journalist working in the daily Al-Shorouk in Egypt. “I would love to see him as a minister of scientific research, but I’m not sure he has what it takes to be a president.”

Zewail became a naturalized citizen of the United States in 1982. It is important to note that, according to the constitution, he cannot run for presidency since he has a dual nationality.

What do you think? Do you think it would help Egypt to have someone like Zewail be president at this stage? Have your say in the comments below.

Energy and agriculture from seawater

seawater greenhouse jordan.jpgJordan has signed an agreement with Norway to produce an ambitious hybrid project to promote agriculture and produce renewable energy, reports SciDev.Net.. The seawater will be pumped inland where it will be purified for use in greenhouse agriculture. A nearby concentrated solar power plant will provide the power for the desalination process. Some of the water produced will, in turn, be used to cool down solar power plant. This cycle will then continue supplying energy and pure water.

Construction of the project should start in 2012, but will not be complete till 2015.

Jordan is one of the driest countries in the Middle East, and probably in the world too. Annual water per person there amounts to less than 200 cubic metres. Compared to the world average of 7,000 cubic metres, water security in Jordan is obviously one of the biggest challenges. While I was in Amman, I realized that water is only delivered three days a week and residents have to store it in large tanks for later use. If you run out of your supplied water, you have to buy expensive extra water to use.

The new project will be started on a 20-hectare area provided by the government of Jordan. Norway will then fund three feasibility studies to determine how successful the project is. If it is successful, Jordan will expand it into 200 extra hectares of desert land.

Protestors call on Egyptian antiquities chief to resign

hawass240.jpgThis article first appeared in Nature

Ewen Callaway

Zawi Hawass, Egypt’s high profile head of antiquities, is under fire over his ties to the country’s former president and his showy leadership style.

About 150 university archaeology graduates called for Hawass to quit, in a peaceful protest outside his offices yesterday, according to the Associated Press. In the days before Egyptian president Hosni Mubarak stepped down, Hawass accepted a post in Mubarak’s cabinet. Hawass also had said, before the president stepped down on Friday, that Egyptians should give Mubarak a chance at reform.

Protesters assembled outside of Hawass’ office in Cairo also complained of poor pay and Hawass’ self-aggrandizement. “He doesn’t care about us,” Gamal el-Hanafy, a 22-year-old graduate of Cairo University told AP. “He just cares about propaganda.”

“A technological revolution”

Egyptian Revolution Facebook.jpg"The only thing that will carry Egypt forward in the coming period is scientific thinking," said Ahmed Zewail, winner of the Nobel Prize for Chemistry in 1999 on Egyptian State TV. “If you install this core value in young people in a proper manner, you will have a whole generation of Egyptians with nearly unlimited potential.”

After the resignation of President Mubarak, in power since 1981, Egyptians went out celebrating all over Egypt. Everyone is aware, however, that this is only the first step of rebuilding their country.

Zewail, interviewed on State TV, talked about the role of scientists in the upcoming period.

He compared the future of Egypt to India’s investment in science, and how it had paid off, propelling the country ahead. He stressed that Egypt will need to encourage critical thinking in the new young generation in order to tap into their dormant potential. “Around 35% of the Egyptian population are 14 years old or younger. If you invest in these then you will create a powerful workforce that can truly change Egypt.”

“You can never enter the 21st century with 30% of the population illiterate. The world has moved ahead from that and there are many plans worldwide on how to counter that.”

After winning the Nobel prize, Zewail put together a proposal for a complete overhaul of science research and education in Egypt. He presented it to the Egyptian government for discussion, but the plans were halted for unknown reasons over and over again. Zewail said he had talked with five different governments, but the result was always the same.

He told a caller that he would work on a new plan to present to the upcoming government to solve some of the country’s most glaring problems. “I would give this all my time, but what would be different about it is that I’m completely convinced that any vision for Egypt in the coming years will not be complete unless the young people of Egypt are part of this.”

Zewail praised the young people who carried the first sparks of the revolution, calling it “a technological revolution” for the role that technology, the internet and social media has played in it.

Taking a question from a well-known Islamic preacher about the relation between science and religion, Zewail said that there was an unfortunate misunderstanding in Egypt that is often exaggerated by what he called “an ignorance of religion.”

“I don’t see there is any contradiction between science and religion whatsoever. Science looks into facts. I notice that a lot of people who talk about science, especially on satellite channels, are not up to the standard of knowledge to talk about it in an analytical manner.

Several callers asked Zewail to return to Egypt and play a role in the rebuilding of Egypt. One caller even asked him to run for presidency in the upcoming elections in September 2011. Zewail did not elaborate his futre plans, but he promised that he will announce “several good initiatives soon.”

University professors join protest en mass

Egypt Protest University faculty.jpgAs the protests in Egypt enter their 15th day, thousands of university professors, faculty and students joined the demonstrations, marching through the streets from Cairo University on their way to Tahrir Square, the gathering place of the protesters since the start of the uprising.

Activates estimate the number of university faculty who have joined at around 50,000. While the number may be an over-estimation, this is still the largest and most organized protest held by university members since the start of the escalated events.

Professors held up signs against the regime, chanting “Down down with Mubarak” and “The people have decided, the regime must fall.” The marchers lamented the lack of freedom in science research and the miserable condition of laboratories and public universities.

School teachers joined the marching professors as well, frustrated at the mediocre quality of education in schools and their low wages.

The protesters tried to reach Tahrir Square but were blocked by the army – where they had to make a detour. But instead of heading to the square through another street, they led the protest to the Houses of Parliament where they did a sit-in in front of the large building calling for their demands.

Student protesters who have been sleeping in Tahrir Square for several days headed out and joined their professors in front of the House of Parliament. The protesters then expanded the area they hold, vowing to sleep in ahead of the House of Parliament until their main demand, Mubarak stepping down, is met.

Doctors defiant in the face of violence

Injured man during Tahrir protests.jpg

The protests taking place in Egypt over the past 10 days have been largely peaceful. However, things took a sharp turn into violence on Wednesday leading to thousands of injuries and several deaths.

Clashes erupted between pro-democracy protesters, who have settled in Liberation Square downtown, and pro-President Mubarak protesters. These protesters came up close to the square and started throwing rocks and stones at the pro-democracy protesters. Moments later the sky started raining rocks on the people protecting the Square. The clashes continued well into the night, lasting for more than 12 hours nonstop and even more dangerous as the attackers started throwing makeshift bombs as well.

As rocks, stones, molotov bombs and petrol bombs rained on the protesters, surgeons among the protesters quickly set up a makeshift emergency unit close to the sieged entrance of the Square. These doctors were there as protesters, not as professional doctors, and thus had no proper equipment nor tools to treat the injured. They had to make use with simple makeshift tools to stitch, stop gushing blood, and treat serious burns.

Further away in the nearby mosque, they set up a better emergency clinic to treat more serious injuries. The mosque was divided between the newly set up clinic and a separate area to house the older women and children protesters away from the violence outside so they are not harmed.

The doctors had to work relentlessly for long hours as protesters kept carrying or dragging injured in. At one point, it seemed like everyone in the Square was bleeding. People called friends and reached out through social networks asking supporters to head to Liberation Square to bring much needed medical supplies.

Many of those delivering medical supplies in to the protesters from outside were beaten up on their way and had their supplies stolen. But what little did make it through was much needed to help people, but sadly it was not enough. Many who could’ve been saved in a fully-equipped hospital died due to the lack of one.

The Los Angeles Times recounts the events of that night through the eyes of one of the doctors here.

Egyptians rally to defend cultural heritage

As petrol bombs fly near the Egyptian Museum, citizens and army mobilize against looters.

“I’m a little shaken. They are throwing Molotov cocktails towards the museum.” Sarah Parcak, an archaeologist at the University of Alabama, Birmingham, who has spent the past 12 years working in Egypt, was speaking yesterday as the Al Jazeera TV news network showed live footage of running street battles around the Egyptian Museum at Tahrir Square in Cairo. “We are all nervous and scared, first and foremost for the people, but now the museum, a symbol of Egypt’s vast cultural heritage and treasures, is being threatened by Mubarak’s own people,” she said.

The military quickly extinguished the fires caused by the firebombs, but the battles around the museum continued throughout the night, with several more petrol bombs landing near the museum. Trouble had started yesterday when people loyal to President Hosni Mubarak mounted orchestrated attacks against the peaceful protesters, beating them, throwing rocks and petrol bombs, and shooting into the crowds.

So far, the protesters have held their ground against the onslaught, but the night’s battles have left at least 8 dead and 900 wounded.

Military priorities often take precedence during conflicts, while loss of life is the immediate concern in a humanitarian crisis. But efforts must nonetheless also be made to preserve artefacts, sites and monuments that are part of a nation’s cultural heritage, and also vital to understanding its history. Balancing these concerns is a problem that the international community has grappled with for decades.

“We are all very concerned about the Egyptian Museum, but please what we need first is to restore order and save the Egyptian people.”

The massive destruction of cultural heritage during the Second World War prompted the adoption of the Convention for the Protection of Cultural Property in the Event of Armed Conflict in 1954 at The Hague in the Netherlands. Signatories to the Convention pledge to take measures such as creating maps and inventories of cultural heritage, and to set up military units with expertise in archaeology and the protection of key sites and artefacts. In principle, governments and armies should draw up heritage-protection plans during peacetime, which can be activated once a conflict starts.

But implementation of the treaty varies widely. “There is much work to do,” says Julien Anfruns, director-general of the International Council of Museums, and president of the International Committee of the Blue Shield – the cultural equivalent of the Red Cross. “The Hague Convention is important, and the chaos over the past few days makes it even more important,” says Frank Rühli, who co-heads the Swiss Mummy Project at the University of Zurich’s Institute of Anatomy in Switzerland.

Egypt is a signatory to the Hague treaty, but few details are known about the heritage-protection plans of its military. It is clear, however, that the military was initially caught off guard by the recent surge in protests in Egypt, taking several days to secure the country’s main museums and sites.

“There was a period at the beginning that was dangerous. Now it seems that main sites are protected by military,” says Rühli, who had been scheduled to fly to Egypt this week to work in the Valley of Kings, but now doubts that his team will be able to resume its work there before the end of the year.

People power

Under normal conditions, Egypt’s archaeological sites are “amazingly well guarded”, says Parcak, for example by the Egyptian Supreme Council of Antiquities’ (SCA) security guards. She attributes this effort to Zahi Hawass, head of the council, who was made minister of antiquities — a new position — in Mubarak’s new government sworn in on 31 January. “He will be doing everything in his power to make sure the sites are protected,” she says.

“Egypt’s ancient heritage is so rich that the whole country is basically one large open-air museum.”

But in the early days of the uprising, the unrest provided a window of opportunity for looters. Young citizens responded by helping the SCA’s security guards, forming vigilante groups to protect sites. They formed a human chain around the Egyptian Museum on the first night of rioting in the vicinity, for example, and so prevented any serious damage or thefts.

Ismail Seregeldin, director of the Library of Alexandria, issued a statement on 30 January to thank the youth for protecting the library from “lawless bands of thugs, and maybe agents provocateurs”. The Library would remain closed, he added, until greater security returned.

In a statement yesterday, Hawass said that the army was now protecting all 24 national museums, including the Egyptian Museum, the Coptic Museum and the Museum of Islamic Art in Cairo, as well as all the major archaeological sites, including Luxor, Aswan, Saqqara and the pyramids of Giza. The local population are guarding the San el-Hagar site in the Nile Delta.

Impossible task?

But many researchers fear that it may be impossible to protect all the country’s important heritage sites, leaving some vulnerable should the security situation worsen. “Egypt’s ancient heritage is so rich that the whole country is basically one large open-air museum. It would be impossible to station a soldier at the door of each and every tomb,” says Margaret Maitland, a graduate student in Egyptology at the University of Oxford, UK, who has been collating information about lootings and damage on her blog, The Eloquent Peasant.

Meanwhile, researchers are struggling to assess any losses or damage to artefacts, hampered by continuing difficulties in getting reliable information from inside the country. Parcak has created a Facebook page, Restore + Save the Egyptian Museum!, where archaeologists are sharing information on damage and looting, and trying to separate fact from rumour.

So far it seems that the damage to the Egyptian Museum on 28 January, when 10 men descended into the museum on ropes from glass panes on the roof, was limited, with around 70 objects broken. A warehouse storing antiquities was also looted in Qantara in the Sinai, but most of the roughly 300 stolen objects have been recovered. Padlocks on tombs in Saqqara were broken, but no damage to the tombs was reported.

Rühli hopes that Egypt will call on external experts to form an international mission to assess the damage, and decide what restoration is needed. Such a mission could also assess the security at sites, and how this might be improved. Jan Hladík, a specialist in cultural heritage at the United Nations Educational, Scientific and Cultural Organization (UNESCO), notes there was a similar UNESCO mission during the Iraq War, in 2003. Researchers have also called on law-enforcement agencies and art dealers around the world to look out for stolen Egyptian antiquities.

For those in the thick of the fighting, however, Egypt’s vast heritage is understandably not the most pressing priority. “We are all very concerned about the Egyptian Museum, but please what we need first is to restore order and save the Egyptian people,” one member of the Restore + Save the Egyptian Museum! Facebook page posted last night, after returning from the bloody clashes in Tahrir Square.

Fresh danger surrounds the Egyptian Antiques Museum

human wall around museum.jpg

The Egyptian Antiquities Museum, home to some of the most important artifacts ever and the largest collection of treasures from ancient Egypt, was under threat a third time yesterday in less than a week as a result of the ongoing protests in Cairo, Egypt.

After a day of very peaceful protesting on Tuesday, deadly clashes erupted between protesters calling for the regime to step down and others calling on President Mubarak to stay on Wednesday. Pro-Mubarak protesters tossed molotov and petrol bombs at the anti-Mubarak protesters gathering in Liberation Square for at least 10 hours continuously.

Now, the Egyptian Antiquities Museum lies right at the entrance to Liberation Square. Several of these bombs fell very close to the museum, igniting fears for the precious collections inside. A car parked right outside the museum and a large tree caught fire an hour or so before dawn, but protesters and military soldiers who were protecting the museum quickly rushed to put the fires out. A fire truck which is now permanently parked within the museum’s courtyard also quickly turned its hoses at the fire to stop it before it spread any further.

Thankfully, the fires were controlled before they spread any further into the museum. This morning security around the museum has increased and everyone, both civilians and military, are rather tense. They don’t allow anyone to linger around for too long around the museum and quickly rush people who try to get too close away.

Earlier this week, fires broke out in surrounding buildings, threatening the museum. People desperately tried to control the fires during a near complete lack fire trucks before the military intervened to help. Gangs of looters also tried to break in and steal some of the priceless pieces within several times. When they failed to steal anything, they smashed many of the glass cases and damaged at least one statue of the boy-king Tutankhamun. To protect the museum, protesters had formed a human shield surrounding it for several days before the military took over.

Below is a video I shot from the protest today showing what the museum looks like from the outside now, and the damage in the area surrounding it.
