Timbuktu’s vulnerable manuscripts are city’s "gold"

French and Malian troops surrounded Timbuktu on Monday and began combing the labyrinthine city for Islamist fighters. Witnesses, however, said the Islamists, who claim an affiliation to al Qaeda and had imposed a Taliban-style rule in the northern Malian city over the last ten months, slipped into the desert a few days earlier.

But before fleeing, the militants reportedly set fire to several buildings and many rare manuscripts. There are conflicting reports as to how many manuscripts were actually destroyed. (Video: Roots of the Mali Crisis.)

On Monday, Sky News posted an interview with a man identifying himself as an employee of the Ahmed Baba Institute, a government-run repository for rare books and manuscripts, the oldest of which date back to the city's founding in the 12th century. The man said some 3,000 of the institute's 20,000 manuscripts had been destroyed or looted by the Islamists.

Video showed what appeared to be a large pile of charred manuscripts and the special boxes made to preserve them in front of one of the institute's buildings.

However, a member of the University of Cape Town Timbuktu Manuscript Project told eNews Channel Africa on Tuesday that he had spoken with the director of the Ahmed Baba Institute, Mahmoud Zouber, who said that nearly all of its manuscripts had been removed from the buildings and taken to secure locations months earlier. (Read "The Telltale Scribes of Timbuktu" in National Geographic magazine.)

A Written Legacy

The written word is deeply rooted in Timbuktu's rich history. The city emerged as a wealthy center of trade, Islam, and learning during the 13th century, attracting a number of Sufi religious scholars. They in turn took on students, forming schools affiliated with's Timbuktu's three main mosques.

The scholars imported parchment and vellum manuscripts via the caravan system that connected northern Africa with the Mediterranean and Arabia. Wealthy families had the documents copied and illuminated by local scribes, building extensive libraries containing works of religion, art, mathematics, medicine, astronomy, history, geography, and culture.

"The manuscripts are the city's real gold," said Mohammed Aghali, a tour guide from Timbuktu. "The manuscripts, our mosques, and our history—these are our treasures. Without them, what is Timbuktu?"

This isn't the first time that an occupying army has threatened Timbuktu's cultural heritage. The Moroccan army invaded the city in 1591 to take control of the gold trade. In the process of securing the city, they killed or deported most of Timbuktu's scholars, including the city's most famous teacher, Ahmed Baba al Massufi, who was held in exile in Marrakesh for many years and forced to teach in a pasha's court. He finally returned to Timbuktu in 1611, and it is for him that the Ahmed Baba Institute was named.

Hiding the Texts

In addition to the Ahmed Baba Institute, Timbuktu is home to more than 60 private libraries, some with collections containing several thousand manuscripts and others with only a precious handful. (Read about the fall of Timbuktu.)

Sidi Ahmed, a reporter based in Timbuktu who recently fled to the Malian capital Bamako, said Monday that nearly all the libraries, including the world-renowned Mamma Haidara and the Fondo Kati libraries, had secreted their collections before the Islamist forces had taken the city.

"The people here have long memories," he said. "They are used to hiding their manuscripts. They go into the desert and bury them until it is safe."

Though it appears most of the manuscripts are safe, the Islamists' occupation took a heavy toll on Timbuktu.

Women were flogged for not covering their hair or wearing bright colors. Girls were forbidden from attending school, and boys were recruited into the fighters' ranks.

Music was banned. Local imams who dared speak out against the occupiers were barred from speaking in their mosques. In a move reminiscent of the Taliban's destruction of Afghanistan's famous Bamiyan Buddha sculptures, Islamist fighters bulldozed 14 ancient mud-brick mausoleums and cemeteries that held the remains of revered Sufi saints.

A spokesman for the Islamists said it was "un-Islamic" for locals to "worship idols."

Jodi Arias Borrowed Gas Cans Before Killing Ex

Accused murderer Jodi Arias borrowed two five-gallon gas cans from a former boyfriend the day before she drove to Arizona to kill another ex, Travis Alexander, according to testimony in Arias' murder trial today.

In cross examination, prosecutors also forced Arias' former live-in boyfriend Darryl Brewer to describe his sex life with Arias as "pretty aggressive."

Brewer, 52, dated Arias for four years and shared a home with her in California for two years. He told the court today that Arias called him in May 2008, asking to borrow gas cans, but would not explain why. She called him again at least two more times, and arrived at his house on June 2008, to borrow the cans.

On the day she picked up the gas cans she told Brewer that she was going to visit friends in California and Arizona.

Prosecutors argue that Arias then drove to Mesa, Ariz., where she allegedly had sex with Alexander, took nude photos of him, and then stabbed him 27 times, slashed his throat, and shot him twice in the head. She is charged with murder and could face the death penalty if convicted.

Arias, who claims she killed Alexander in self defense, had approached prosecutors two years ago offering to plea to a second degree murder charge, which could carry a 25 year term, but the state rejected the offer, Nancy Grace reported on Good Morning America today.

Brewer said that Arias never returned the gas cans. The pair had been broken up two years earlier and they had only spoken "sporadically," he said.

Prosecutors also showed receipts from Arias' trip from her California home to Alexander's home in Mesa, showing that she purchased a 10 gallons of gas at one gas station the night before she drove to Arizona, and then another 10 gallons from a different gas station 10 minutes later. Prosecutors are expected to argue she brought the gas with her to fill up her car secretly on the way to Alexander's home, showing premeditation for the murder.

Arias' attorneys called Brewer as one of their first witnesses as they began mounting their case that Arias killed Alexander in self defense, arguing that Alexander was controlling and abusive toward Arias.

They asked Brewer to explain how he and Arias had been in a stable relationship for four years, from 2002 to 2006, and had bought a home together before Arias met Alexander at a business conference and began to change.

"I saw a lot of changes in Jodi. She became a different person than I had known previously," Brewer said, describing how Arias' behavior changed in May 2006 when she joined a company called Pre-Paid Legal. There, she met Alexander and began seeing him. She continued to live with Brewer.

"She had continued to pay the mortgage, but she was not paying other household bills, she began getting into debt or financial trouble," Brewer said. "For me it seemed she was not as rational or logical."

Arias also converted to Mormonism while living with Brewer, telling him that he could no longer curse and she would no longer have sex with him because she was saving herself for marriage.

The pair had previously had an "enthusiastic" and "aggressive" sex life, Brewer admitted to prosecutors. They had engaged in anal sex, Arias had taken nude photos of Brewer, and Arias had purchased breast implants in 2006, he testified.

Brewer said that after Arias began to change, he made arrangements to move closer to his son from his first marriage, and he and Arias broke up.

They kept in touch with occasional phone calls until Arias asked to borrow the gas cans in June 2008, and then called him a week after borrowing the cans to say that her friend had been killed.

Martinez, reading notes from an interview Brewer gave to authorities during the investigation into Alexander's death, asked if Arias had ever mentioned needing an "alibi." Brewer said he did not recall any conversation about alibis.

"After this date of June 4, 2008," Martinez asked, "you received a call from Jodi Arias, and she was very agitated?"

"She was sad," Brewer said.

"Did she tell you that her friend had been killed and she did not have an alibi?"

"I don't remember that," Brewer said.

Arias was arrested a month after Alexander was found dead, in July 2008.

Iran launches monkey into space

Lisa Grossman, physical sciences reporter

Last summer, the Iranian Space Agency announced their plan to send a monkey into space - and now they've apparently done it.

According to Iranian state-run television, a press release on the space agency's website, and photos of the event, Iran sent a live rhesus monkey into sub-orbital space aboard a small rocket called Pishgam, or Pioneer. There's even a video posted on YouTube that appears to be of the launch (though New Scientist could not confirm its authenticity).

The report has not been confirmed independently, however, and the US air force's North American Aerospace Defense Command (NORAD) has not reported seeing any missile launches from Iran.

But independent observers say the launch looks legitimate.

"Really, I see no reason not to take their word for it," says Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics who also keeps a log of space launches. He says he's convinced by the photos and discussions he's had with several knowledgeable source in online forums.

In photos released on the Iranian Space Agency's website, the rocket looks like the same kind the agency has launched before, but with a larger nose cone designed to fit a small chamber that can support life. Images also showed a live rhesus monkey strapped to a small seat.

The reports say the rocket went straight up 120 kilometres, which McDowell says qualifies as outer space, but not high enough to reach orbit, and came back down with a parachute.

It's unclear exactly when the launch took place. The press release says that the launch happened on the birthday of Mohammed the Prophet, which is celebrated by Shiites on 29 January, but was celebrated last week elsewhere in the world.

Some countries worry that Iranian rockets capable of carrying animals or people could also carry weapons. Iran has denied any military intention.

"This is not a scary thing because this is not a big new rocket that could hit America or anything like that," McDowell says. "There's nothing military to this. It's purely for propaganda. Nevertheless, it advances their science and their technology by being able to do it."

Iran says the launch is a first step towards sending humans into space, which they intend to do in the next 5 to 8 years. To do that, McDowell says, they'll need to build a larger rocket. The country currently has a vehicle called Safir that has successfully put satellites in orbit, and is developing a more powerful launcher called Simorgh.

The next step will probably be to either launch Safir to carry a human to sub-orbital space, or an unmanned Simorgh flight into orbit to make sure mission controllers can return it to the ground safely.

"They don't want to repeat what the Soviets did" in 1957, McDowell says, "which is put a living being in orbit before you figure out how to get it back."

Australia PM's partner apologises for Asian doctor joke

SYDNEY: The partner of Australian Prime Minister Julia Gillard, whose fiery speech against sexism last year made global headlines, apologised Tuesday for making a quip about an "Asian female doctor".

Tim Mathieson made the comment during a reception at The Lodge in Canberra on Monday night attended by members of the West Indies cricket team.

Mathieson, who has worked to raise awareness about men's health issues, brought up the need for men to have regular checks for prostate cancer.

"Go and get that exam that none of us like to have done, but we know we should," Mathieson said. Gillard was standing behind him at the time.

"We can get a blood test for it but the digital examination is the only true way to get a correct reading on your prostate, so make sure you go and do that. And perhaps look(ing) for a small Asian female doctor is probably the best way..."

The comment was met with laughter at the time, but the opposition said Mathieson's remark was in bad taste and he later apologised.

"It was meant as a joke, and on reflection I accept it was in poor taste," he said in a statement.

"I apologise for any offence caused."

Gillard, the nation's first female leader, caused a global stir in October when she lashed out at opposition leader Tony Abbott in parliament, saying she would not be "lectured about sexism and misogyny by this man".

She said Tuesday that Mathieson was passionate about getting out the message to men to get recommended health checks, but agreed the apology was the right thing to do.

"Tim's apologised for a joke that was in poor taste," she said.

Rdio rolls out six months of free streaming in 15 countries

Rdio announced today that it is offering the majority of its international customers the same deal that people get in the U.S.: six months of free music streaming.

The online music service lets users access its library of more than 18 million songs that come without ads or interruptions and can be listened to and shared across the Web, social networks, and mobile devices.

"The countries that will have free access to Rdio are the United States (where it's been free since October 2011), United Kingdom, Australia, Belgium, Canada, Denmark, Estonia, Finland, France, Netherlands, New Zealand, Norway, Portugal, Spain, and Sweden," a Rdio spokesperson told CNET in an email. It is not yet available in Brazil or Germany.

According to PCMag, a Rdio spokesperson said that the expansion is meant to "attract international users and to heat things up competitively as we expect this will drive a lot more users."

Rdio launched in the U.S. in August 2010 as an alternative to other music streaming services. It has since rolled out its service to Facebook. Last October, Rdio founder Janus Friis launched the Rdio Artist Program, which is designed to give musicians better commission rates by removing the idea of payment-per-song that some other services use.

As of now, new users in the 15 countries that get the six months of free streaming can upgrade at any time to one of the service's subscription plans. In the U.S., the plans are $4.99 per month for unlimited Web streaming and $9.99 per month for unlimited Web, mobile, and offline listening. Prices differ by country.

Space Pictures This Week: Martian Gas, Cloud Trails

The sun is more than meets the eye, and researchers should know. They've equipped telescopes on Earth and in space with instruments that view the sun in at least ten different wavelengths of light, some of which are represented in this collage compiled by NASA and released January 22. (See more pictures of the sun.)

By viewing the different wavelengths of light given off by the sun, researchers can monitor its surface and atmosphere, picking up on activity that can create space weather.

If directed towards Earth, that weather can disrupt satellite communications and electronics—and result in spectacular auroras. (Read an article on solar storms in National Geographic magazine.)

The surface of the sun contains material at about 10,000°F (5,700°C), which gives off yellow-green light. Atoms at 11 million°F (6.3 million°C) gives off ultraviolet light, which scientists use to observe solar flares in the sun's corona. There are even instruments that image wavelengths of light highlighting the sun's magnetic field lines.

US Mom Missing in Turkey Took Side Trips

Sarai Sierra, the New York mother who disappeared in Turkey while on a solo trip, took several side excursions out of the country, but stayed in contact with her family the entire time, a family friend told ABC News.

Turkish media reported today that police were trying to establish why Sierra visited Amsterdam and Munich. Police were also trying to establish the identity of a man Sierra, 33, was chatting with on the Internet, according to local media.

Rachel Norman, a family friend, said the man was a group tour guide from the Netherlands and said Sierra stayed in regular touch with her family in New York.

Steven Sierra, Sarai's husband, and David Jimenez, her brother, arrived in Istanbul today to aid in the search.

The men have been in contact with officials from the U.S. consulate in the country and plan to meet with them as soon as they open on Tuesday, Norman said.

After that, she said Sierra and Jimenez would meet with Turkish officials to discuss plans and search efforts.

Sarai Sierra was supposed to fly back to the United States on Jan. 22, but she never showed up for her flight home.

Her two boys, ages 11 and 9, have not been told their mother is missing.

Sierra, an avid photographer, left New York on Jan. 7. It was her first overseas trip, and she decided to go ahead after a friend had to cancel, her family said.

"It was her first time outside of the United States, and every day while she was there she pretty much kept in contact with us, letting us know what she was up to, where she was going, whether it be through texting or whether it be through video chat, she was touching base with us," Steven Sierra told ABC News before he departed for Istanbul.

But when it came time to pick her up from Newark Liberty International Airport in New Jersey, Sierra wasn't on board her scheduled flight.

Steven Sierra called United Airlines and was told his wife had never boarded the flight home.

Further investigation revealed she had left her passport, clothes, phone chargers and medical cards in her room at a hostel in Beyoglu, Turkey, he said.

The family is suspicious and said it is completely out of character for the happily married mother, who met her husband in church youth group, to disappear.

The U.S. Embassy in Turkey and the Turkish National Police are involved in the investigation, WABC-TV reported.

"They've been keeping us posted, from my understanding they've been looking into hospitals and sending out word to police stations over there," Steven Sierra said. "Maybe she's, you know, locked up, so they are doing what they can."

DNA privacy: don't flatter yourself

The secrets contained in our individual genomes are less valuable than we like to believe

IMAGINE donating your DNA to a project aimed at discovering links between genes and diseases. You consent to your genome sequence being released anonymously into the public domain, though you are warned there is a remote possibility that it might one day be possible to link it back to you.

A few years later, that remote possibility comes to pass. How should you feel? This is no longer a hypothetical scenario. About 50 people who participated in a project called 1000 Genomes have been traced (see "Matching names to genes: the end of genetic privacy?").

The researchers' intentions were honourable. They have not revealed these identities, and the original data has been adjusted to make a repeat using the same technique impossible. All they wanted to do was expose privacy issues.

Consider them exposed. It is clear that genomics has entered a new phase, similar to that which social media went through a few years ago, when concerns were raised about people giving away too much personal information.

What happens when the same applies to our DNA? Having your genome open to public scrutiny obviously raises privacy issues. Employers and insurers may be interested. Embarrassing family secrets may be exposed.

But overall, personal genetic information is probably no more revealing than other sorts. In fact there are reasons to believe that it is less so: would an insurance company really go to the trouble of decoding a genome to discover a slightly elevated risk of cancer or Alzheimer's disease?

The available evidence suggests not. In 2006, Harvard University set out to sequence the genomes of 100,000 volunteers and make them publicly available, along with personal information such as names and medical records. One of the goals was to see what happens when such data is open to all. The answer seems to be "not a lot". So far this Personal Genome Project has published 148 people's full genomes. Not one volunteer has reported a privacy issue.

This is not a reason for complacency, but it suggests that our genomic secrets are less interesting to other people than we might like to believe.

Sensitive skin problems aren't skin deep

SINGAPORE: Most might assume that sensitive skin is mainly due to in an intake of the wrong food, or the application of the wrong product.

However, the main reason for sensitive skin lies on the surface of the skin, and what that layer is subjected to from the daily environment.

In a sensitive skin survey held by Curél, the dermatological research oriented brainchild of Japanese chemical and cosmetics giant Kao, almost half of the respondents from various countries claimed to suffer from sensitive skin.

And within this number, Singaporeans make up a whopping 70 percent.

Part of the reason lies in Singapore's tropical climate –from wet and rainy, to sunny but humid – coupled with hours spent in drying air-conditioned environments whether at work, home or even shopping.

More precisely, as explained by Curél's skincare expert Koicihi Ishida, skin in the Singapore environment is subject to "enhanced blood circulation and skin dryness due to the rapid change of the temperature and humidity within a short time frame".

"At high temperatures and humidity, skin cells swell when sweat is produced, reducing the skin's barrier function" he explains.

"On the other hand, low temperatures and a humidity level of 50 percent or less will cause the skin's moisture to decrease directly and become dry. Either way, the skin becomes sensitive and easily irritated."

In other words, the root of the problem of sensitive skin isn't skin deep.

In fact, it lies with the outermost layer of the skin, known as the stratum corneum (SC).

It is the first barrier between the skin and the external environment, and offers protection to the underlying tissue from infection, dehydration, chemicals and physical stress.

The top layer stratum corneum is largely held together by ceramide.

According to Curél, about half of all sensitive skin cases is due to the SC's impaired function, making it the main cause, as well as solution, to various sensitive skin conditions.

As skin expert Ishida points out, sensitive skins possess low levels of ceramide, a key element in the SC.

In developing a skincare range that targets sensitive skin, Curél therefore focused its attention on ceramide and replenishing the skin's supply of this intercellular lipid.

Tackling the problem from within also helps, with an intake of naturally occurring ceramide in food stuffs such as soya beans, spinach, rice, wheat flour and the high-fibre, jelly-like konjac or konnyaku, as the product is known in Japan where it's often served in oden or as noodle strips.

Ceramide works by fusing with the skin's moisture and oil to prevent moisture loss while holding skin cells together, similar to a brick and mortar structure that creates a barrier function for the SC.

With ceramide care, sensitive skin is directly treated to improve and replenish the impaired SC barrier which will in turn suppresses the sensitive symptoms and conditions, making the skin more resistant to external irritants.

But this is not a one-hit, one-week solution as the experts will point out.

The newly recovered skin can revert to its troubled state without proper maintenance, or in the case of more serious skin conditions such as atopic dermatitis, where ceramide drops to its original low state.

The Curél skincare range for sensitive skin runs a gamut of applications, from face and body to scalp and hair, and everyone from adults to babies, are supposed to be able to use the products.

How could so that be so?

"Although the two skin types may differ in thickness, appendices and sensitivity, the fundamental structure and function of the skin is common for the young and old of both sexes," explains Ishida.

"For the elderly, they have dry skin due to old age and it's usually accompanied with itchiness, which can be seen especially on the lower thigh area. In many cases, their SC's barrier function is damaged."

The same concept of reinforcing the SC's protective function applies to babies and the young, as the risk of sensitive skin is in fact higher in the young, than when a person ages.

"After birth, a baby's skin tends to be influenced by the environment and thus its skin condition might worsen as it is naturally delicate and sensitive," Ishida points out, while adding that "it is proven by the mild skin care from an early stage that a baby can maintain the healthy skin after growing up."

"Therefore, it is important to have a skincare regime from an early stage to prevent skin issues during their growing up process" he advises.

So even if you don't suffer from sensitive skin, there's little reason not to protect your skin the way it has been protecting you all this while.

Nokia to offer paid upgrade to Lumia-only music service

Music+ will offer premium music options to subscribing Lumia owners.

(Credit:
Nokia)

A few months after jumping in to the free music streaming sector, Nokia is getting ready to give its Lumia-only service a jump-start with a premium upgrade.

Nokia Music+, an upgrade to the free Mix Radio service that Nokia launched last September, will offer Lumia owners unlimited skips and unlimited downloads, the Finnish handset maker announced in a company blog post today. The service also will offer higher quality streams, allowing downloads at eight times the existing quality.

The new service will also offer lyrics for users' mobile device and a Web app for home use.

"Nokia Music is great for discovering new music, and we've found that there's a core of users that want even more of it," Nokia vice president of entertainment Jyrki Rosenberg said in the post. "This is how Nokia Music+ came about."

The service is expected to roll out in the coming weeks with a price of around $3.99 a month.

The Lumia line helped turn around Nokia's fortunes in the fourth quarter, contributing to the handset maker's profit of 202 million euros ($269 million), a massive gain over the 1 billion euros the company lost during the same period in 2011. However, despite sales off 4.4 million Lumia units worldwide, revenue fell from 10 billion euros in the fourth quarter of 2011 to 8 billion last quarter.
