SF officials: Possible 1 plane victim run over

SAN FRANCISCO (AP) ? San Francisco fire officials say there is a possibility that one of the two teenage girls killed in a plane crash at San Francisco International Airport was struck by an emergency vehicle.

Fire Chief Joanne Hayes-White and Assistant Deputy Chief Dale Carnes both raised the possibility at a news conference with first responders on Monday.

San Mateo County Coroner Robert Foucrault earlier said his office is conducting an autopsy to determine whether one of the victims was run over and killed by a responding vehicle.

He said his staff was notified of the possibility by senior San Francisco Fire Department officials at the crash site on Saturday. More than 180 people were sent to hospitals following the crash.

T-shirt store starts new fashion trend in Libya's Benghazi

By Feras Bosalum

BENGHAZI, Libya (Reuters) - Browsing through the racks of printed T-shirts and scarves, a handful of shoppers inspect the latest designs in what has become one of the most popular clothing stores in the eastern Libyan city of Benghazi.

One of them, Ali, a student, holds up a T-shirt printed with a popular Libyan expression "Grab what is new before it becomes old", one of the many catchphrases that adorn the designs in Boza, a small shop in an upmarket neighbourhood.

"I always bought clothes with English writing on them but now for the first time, I am buying a T-shirt with Arabic print," he said. "I am so happy."

Ali is one of the hundreds of Libyans who have flocked to Boza since it opened a few months ago, eager to get their hands on designs that have become a talking point among the youth in Benghazi's popular coffee shops.

Its name meaning "stylish", the store - the first of its kind in Libya according to its owners - sells T-shirts, bags, head and neck scarves printed with "Made in Libya", "Walk like a Libyan" or a jumble of letters spelling out Benghazi.

Some T-shirts are printed with "I love Cyrenaica", referring to Libya's eastern province where calls for more regional autonomy have heightened since Muammar Gaddafi's ouster in 2011.

Benghazi was the cradle of the Libyan revolt and discontent has mounted over continued neglect from Tripoli. Easterners say their oil-rich region was starved of cash under Gaddafi.

Other colourful T-shirts carry portraits of King Idris, whom Gaddafi ousted in his 1969 coup.

"Our designs have political messages, it is difficult to separate daily life from politics," Ahmed Benmussa, a 32-year old oil engineer and Boza co-owner, said.

"We take inspiration from Libyan heritage because we have a rich culture. Reviving history is one of our aims."

Some of the T-shirts tackle the serious issues plaguing post-war Libya - the mass of weapons on its streets and the armed militias which have hobbled governance.

"Better the devil you know" reads the message on one T-shirt accompanied by the drawing of a knife.

"Some of the messages are critical, perhaps in a more humorous way," Benmussa said. "This is how we express ourselves, unlike those who actually use weapons."

PERSONALISED DESIGNS

The shop itself is a mix between old and new. An old record player lies idle in the middle of the store while a large television screen beams Boza's latest designs.

Importing blank T-shirts and scarves from Turkey, its designers use a small printing machine to decorate the clothes and accessories. Customers can also personalise goods or propose new designs on a "suggestion wall" in the store.

Boza's T-shirts, which sell for around 50 Libyan dinars, are popular among Benghazi's youth who say the designs allow them to express themselves - a still relatively new freedom after Gaddafi's 42-year iron-fisted rule.

"This is a great way in which you can express yourself in a modern and fashionable manner," Alaa al-Baba, a 24-year old engineer, said. "It would be great if everybody could do that."

Boza's owners use social media site Facebook to promote the store, both at home and abroad, posting pictures of the owners' friends wearing designs around town like professional models.

"We have sent T-shirts to customers in Saudi Arabia, Germany, the United Kingdom, Indonesia, United States, Qatar, Ireland, France, Egypt and Spain," Benmussa said.

Capitalising on Boza's success in Benghazi, plans are now under way to open a branch in the capital.

"There will be a Boza in Tripoli in coming days," he said.

Obama: US will give allies info on spying claims

(AP) ? Facing a European uproar over more U.S. eavesdropping claims, President Barack Obama argued Monday that it's no surprise that governments spy on each other but said the United States will provide allies with information about new reports that the National Security Agency bugged European Union offices in Washington, New York and Brussels.

The latest revelations were attributed in part to information supplied by former NSA contractor Edward Snowden. Obama on Monday also said the U.S. has held "high-level" discussions with Russians to get Snowden out of a Moscow airport and back to the United States to face criminal charges.

Obama, in a news conference with Tanzanian President Jakaya Kikwete, pushed back against objections from key allies over a report in the German news weekly Der Spiegel that the United States installed covert listening devices in EU offices. He suggested such activity by governments is not unusual.

"We should stipulate that every intelligence service ? not just ours, but every European intelligence service, every Asian intelligence service, wherever there's an intelligence service ? here's one thing that they're going to be doing: they're going to be trying to understand the world better and what's going on in world capitals around the world," he said. "If that weren't the case, then there'd be no use for an intelligence service.

"And I guarantee you that in European capitals, there are people who are interested in, if not what I had for breakfast, at least what my talking points might be should I end up meeting with their leaders. That's how intelligence services operate," Obama added.

European officials from Germany, Italy, France, Luxembourg and the EU government itself say the revelations could damage negotiations on a trans-Atlantic trade treaty between the EU and the United States. Agreeing to start those talks was one of the achievements reached at meetings last month in Northern Ireland between Obama and the European members of the Group of Eight industrialized economies.

Obama said the NSA will evaluate the claims in the German publication and will then inform allies about the allegations.

At the same time, he tried to reassure allies such as German Chancellor Angela Merkel, French President Francois Hollande and British Prime Minister David Cameron that he relies on personal relationships, not spying, to determine what other leaders have on their minds.

"I'm the end user of this kind of intelligence," he said. "And if I want to know what Chancellor Merkel is thinking, I will call Chancellor Merkel. If I want to know President Hollande is thinking on a particular issue, I'll call President Hollande. And if I want to know what, you know, David Cameron's thinking, I call David Cameron. Ultimately, you know, we work so closely together that there's almost no information that's not shared between our various countries."

Obama's remarks came shortly after Hollande demanded on Monday that the United States immediately stop any eavesdropping on European Union diplomats.

Obama also said law enforcement officials in the U.S. and Russia were working to find a way to get Snowden back to the United States, where he is charged with violating U.S. espionage laws. The U.S. does not have an extradition treaty with Russia. Moreover, Russia has claimed Snowden is not technically on their soil because, while he is in the transit terminal of the Moscow airport, he has not passed through immigration. The U.S. has revoked his passport.

"We are hopeful that the Russian government makes decisions based on the normal procedures regarding international travel and the normal interactions that law enforcement has," Obama said.

How fish swim: Researchers examine mechanical bases for the emergence of undulatory swimmers

June 24, 2013 ? How do fish swim? It is a simple question, but there is no simple answer.

Researchers at Northwestern University have revealed some of the mechanical properties that allow fish to perform their complex movements. Their findings, published on June 13 in the journal PLOS Computational Biology, could provide insights in evolutionary biology and lead to an understanding of the neural control of movement and development of bio-inspired underwater vehicles.

"If we could play God and create an undulatory swimmer, how stiff should its body be? At what wave frequency should its body undulate so it moves at its top speed? How does its brain control those movements?" said Neelesh Patankar, professor of mechanical engineering at Northwestern's McCormick School of Engineering and Applied Science. "Millennia ago, undulatory swimmers like eels that had the right mechanical properties are the ones that would have survived."

The researchers used computational methods to test assumptions about the preferred evolutionary characteristics. For example, species with low muscle activation frequency and high body stiffness are the most successful; the researchers found the optimal values for each property.

"The stiffness that we predict for good swimming characteristics is, in fact, the same as the experimentally determined stiffness of undulatory swimmers with a backbone," said Amneet Bhalla, graduate student in mechanical engineering at McCormick and one of the paper's authors.

"Thus, our results suggest that precursors of a backbone would have given rise to animals with the appropriate body stiffness," added Patankar. "We hypothesize that this would have been mechanically beneficial to the evolutionary emergence of swimming vertebrates."

In addition, species must be resilient to small changes in physical characteristics from one generation to the next. The researchers confirmed that the ability to swim, while dependent upon mechanical parameters, is not sensitive to minor generational changes; as long as the body stiffness is above a certain value, the ability to swim quickly is insensitive to the value of the stiffness, the researchers found.

Finally, making a connection to the neural control of movement, the researchers analyzed the curvature of its undulations to determine if it was the result of a single bending torque, or if precise bending torques were necessary at every point along its body. They learned that a simple movement pattern gives rise to the complicated-looking deformation.

"This suggests that the animal does not need precise control of its movements," Patankar said.

To make these determinations, the researchers applied a common physics concept known as "spring mass damper" -- a model, applied to everything from car suspension to Slinkies, that determines movement in systems that are losing energy -- to the body of the fish.

This novel approach for the first time unified the concepts of active and passive swimming -- swimming in which forcing comes from within the fish (active) or from the surrounding water (passive) -- by calculating the conditions necessary for the fish to swim both actively and passively.
