LONDON/BRUSSELS – Facial recognition software, scanners that detect weapons and cameras that spot nervous people are some of the technologies that could be used more widely to secure public places, but some would require greater acceptance of surveillance in Europe. The deadly attacks in Brussels on Tuesday highlighted the vulnerability of Europe's airports and transport systems. European Union officials, grappling with the conundrum of how to increase security while retaining the openness of society, have convened meetings to discuss aviation and land transport security. Their goal is to be able to monitor passengers unobtrusively while minimizing additional hold ups that create crowds, which can themselves become new targets. Experts say technology cannot solve the problem on its own, but techniques such as facial recognition able to pick out known suspects can help if Europeans decide they want more surveillance.

Not all Muslims speak Arabic." For example, Ismail said, the world's largest Muslim nation is Indonesia, which is not anywhere near the Middle East. "People just don't realize that." It's not just the portrayal of Muslims that is problematic. In several video games, images of the Arab and Muslim world are often inaccurate.

It was a key moment that allowed our species to spread around the world from humble beginnings in Africa. But the migration of our ancestors from the African continent around 50,000 years ago was not helped by the evolution of our noses. In fact, our protruding noses formed as a result of other changes in our face and did not help us adapt to new climates as was previously thought, new research suggests. The researchers used a computer model to simulate the flow of air through human noses, pictured, compared to chimpanzees and macaques. We are flat-faced hominins with external noses that protrude from our faces.

Geri Richmond and Hashemite University molecular biologist Rana Dajani spoke after Richmond's AAAS presidential address to open the 2016 AAAS Annual Meeting. Some of the most intriguing news at the 2016 AAAS Annual Meeting focused on the tiny: a miniscule cosmic ripple born 1.5 billion years ago, and a millimeters-long mosquito responsible for an emerging health crisis. But the science behind these discoveries is huge in scope and in importance, reflecting the ongoing achievement of international research teams addressing complex challenges in science and society. Efforts to track the spread of Zika virus in the Americas, and the landmark discovery of gravitational waves, both demonstrate the power and potential--and the need--for global collaborations between scientists, speakers emphasized at the 11 to 15 February event, held in Washington, DC. In particular, scientists in developing countries must work as equal partners with their counterparts in developed countries to solve border-crossing challenges like climate change and virus outbreaks, said outgoing AAAS President Geri Richmond in her address at the start of the meeting.

Why did our ancestors develop a prominent protruding nose when most primates have flat nasal openings? A new study suggests that our unusual nose may have gained its shape simply as a by-product of other, more important changes in the structure of our face – although other researchers insist that some human noses have been directly shaped by natural selection. One of the many functions of the nose and nasal cavity is to act as an "air conditioner". Together, they make sure that the air an animal breathes in is made warm and humid enough to avoid damaging the delicate lining of the lungs. But Takeshi Nishimura at Kyoto University, Japan, and his colleagues argue that the human nose performs this job poorly.

There are very few data sets telling us what we need to know,

In order to aid the poor, agencies need to map the dimensions of distressed areas and identify the absence or presence of infrastructure and services. But in many of the poorest areas of the world such information is rare. "There are very few data sets telling us what we need to know," says Marshall Burke, an assistant professor of Earth system science at Stanford University.

When William Legrand finally decrypted the string, it did not seem to make much more sense than it did before. But at least it did sound more like natural language, and eventually guided the main character of Edgar Allan Poe's "The Gold-Bug"36 to discover the treasure he had been after. Legrand solved a substitution cipher using symbol frequencies. He first looked for the most frequent symbol and changed it into the most frequent letter of English, then similarly inferred the most frequent word, then punctuation marks, and so on. Both before and after 1843, the natural impulse when faced with some mysterious message has been to count frequencies of individual tokens or subassemblies in search of a clue. Perhaps one of the most intense and fascinating subjects for this kind of scrutiny have been biosequences. As soon as some such sequences became available, statistical analysts tried to link characters or blocks of characters to relevant biological functions.

Zittrain, J. Engineering an election – digital gerrymandering poses a threat to democracy.

All too often we see yet another startup appearing on the scene concentrating on a solution to a problem that doesn't exist. Before you can mutter the digital mantra "technology for technology's sake," it disappears, never to be seen again. Frontdoor doesn't seem to be one of those startups. Co-founder Alain Kapatashungu and his team of city dwellers had grown frustrated with how tedious the old way of searching for an apartment had become. Their research taught them that renters take on average 5,040 minutes to find an apartment, 45 percent of inquiries never receive a reply and a disturbing 50 percent of listings were either fake or scams.
