What the facts tell us about a taboo subject At the end of April, Charles Kenny, a former World Bank economist specializing in international development, published a blistering attack in Foreign Policy entitled “Dumb and Dumber,” with the accusatory subtitle “Are development experts becoming racists?” Kenny charged that a growing number of development economists were turning towards genetic and other intrinsic human traits as a central explanation of national economic progress, often elevating these above the investment and regulatory issues that have long been the focus of international agencies.

FRANKFURT, July 16, 2012 (Reuters) — BASF need not be worried by dominant Asian players' expertise in batteries as the world's largest chemicals maker looks to become a leading provider of materials at the heart of next-generation electric cars. The German group will invest roughly 500 million euros ($609 million) by 2016 trying to become a major force in a market that could be worth tens of billions of dollars in less than a decade. Analysts say it is a gamble worth taking as the car industry looks to develop electric vehicles (EVs) with a range up to 250 km from about 2017. The playing field is essentially level because all players, such as Japanese groups Hitachi ...

LOS ANGELES (AP) — The space weather forecast for Earth looks a bit stormy this weekend, but scientists said not to worry. A solar storm was due to arrive Saturday morning and last through Sunday, slamming into Earth's magnetic field. Scientists said it will be a minor event and they have notified power grid operators, airlines and other potentially affected parties. "This isn't the mother of all anything," said forecaster Joe Kunches at the government's Space Weather Prediction Center in Boulder, Colo. "We don't see any ill effects to any systems." The storm began Thursday when the sun unleashed a massive flare that hurled a cloud of highly ...

LONDON, July 13, 2012 (Reuters) — Scientists in Germany have come up with a new fluid for cooling the expensive batteries in electric cars and thereby extending their life, another potential step in improving the cost efficiency of electric propulsion. The fluid, dubbed CryoSolplus, absorbs heat more effectively than either air or water and could allow for tighter packing of batteries under the hood, according to a team of researchers at the Fraunhofer Institute for Environmental, Safety and Energy Technology in Oberhausen. A new battery pack for an electric car can cost as much as half the total price of the vehicle and operating it at 45 degrees celcius, as in a normal drive on ...

SAN FRANCISCO - Yahoo confirmed Thursday that about 400,000 user names and passwords to Yahoo and other companies were stolen Wednesday. A group of hackers, known as the D33D Co., posted online the user names and passwords for what appeared to be 453,492 accounts belonging to Yahoo and several other websites. The hackers wrote a brief footnote to the data dump, which has since been taken offline: “We hope that the parties responsible for managing the security of this subdomain will take this as a wake-up call, and not as a threat.” The breach comes just one month after millions of user passwords for LinkedIn, the online social network for professionals, were exposed by hackers ...

ScienceDaily (July 11, 2012) — It's a project 500 million years in the making. Only this time, instead of playing on a movie screen in Jurassic Park, it's happening in a lab at the Georgia Institute of Technology. Using a process called paleo-experimental evolution, Georgia Tech researchers have resurrected a 500-million-year-old gene from bacteria and inserted it into modern-day Escherichia coli (E. coli) bacteria. This bacterium has now been growing for more than 1,000 generations, giving the scientists a front row seat to observe evolution in action. "This is as close as we can get to rewinding and replaying the molecular tape of life," said scientist ...
Northern Lights Oddity: Strange Sounds of Auroras Explained

The northern lights of Earth are more than just dazzling light shows — they also generate their own strange applause too, a new study reveals. The same energetic particles that create the dancing, dazzling northern lights high up in Earth's atmosphere also produce strange "clapping" noises just 230 feet (70 meters) from the ground, researchers said. The results vindicate folktales and reports by wilderness travelers, which have long described sounds associated with the northern lights (which are also known as the aurora borealis). "In the past, researchers thought that the aurora borealis was too far away for people to hear the sounds it made," Unto Laine, ...
Heat to electricity with no moving parts

ScienceDaily (July 11, 2012) — Researchers who are studying a new magnetic effect that converts heat to electricity have discovered how to amplify it a thousand times over -- a first step in making the technology more practical. In the so-called spin Seebeck effect, the spin of electrons creates a current in magnetic materials, which is detected as a voltage in an adjacent metal. Ohio State University researchers have figured out how to create a similar effect in a non-magnetic semiconductor while producing more electrical power. They've named the amplified effect the "giant spin-Seebeck" effect, and the university will license patent-pending variations of the ...
Magnetic Sense: Why Powerlines Confuse the Internal Compass of Migrating Birds

ScienceDaily (July 10, 2012) — Migratory birds and fish use Earth's magnetic field to find their way. LMU researchers have now identified cells with internal compass needles for the perception of the field -- and can explain why high-tension cables perturb the magnetic orientation. Although many animal species can sense the geomagnetic field and exploit it for spatial orientation, efforts to pinpoint the cells that detect the field and convert the information into nerve impulses have so far failed. "The field penetrates the whole organism, so such cells could be located almost anywhere, making them hard to identify," says LMU geophysicist Michael Winklhofer. Together ...

The Department of Homeland Security will soon be using a laser at airports that can detect everything about you from over 160-feet away. Gizmodo reports a scanner that could read people at the molecular level has been invented. This laser-based scanner – which can be used 164-feet away — could read everything from a person’s adrenaline levels, to traces of gun powder on a person’s clothes, to illegal substances — and it can all be done without a physical search. It also could be used on multiple people at a time, eliminating random searches at airports. The laser-based scanner is expected to be used in airports as soon as 2013, Gizmodo reports. The scanner is ...

On Monday's show, Professor of Human Genetics at the University of Oxford since 1997, Bryan Sykes, discussed some of his fascinating DNA research findings, including his study of American genetics. The United States' population contains a convergence of DNA from a number of continents, with interesting crossovers such as some African Americans having European genes. According to earlier research (not done by Skyes), Native Americans actually originated from Siberia, China, and even Europe, but the DNA blood testing that yielded these results was done without their consent, and thus raised controversy and ire, he detailed. Interestingly, some people from Britain have been found to ...
Metformin May Help Renew Neurons

— New research suggests that the widely used type 2 diabetes drug metformin may be useful in stroke, Alzheimer's disease, and other conditions involving injured or degenerating brain cells. Animal studies showed that metformin activates a key pathway (aPKC-CBP) that promotes neurogenesis and enhanced hippocampus-dependent spatial memory formation in study animals. Results also showed that the drug has similar activity on human neural precursors, increasing the likelihood that it might enhance neurogenesis in the human brain as well. These findings could provide the basis for a therapeutic strategy for human nervous system disorders, according to the study authors from the ...

Scientist says 'foolish' government focusing on isolated heat waves In the midst of recent wildfires, deadly storms and a record-setting heatwave, many climate change proponents claimed these extreme events were further proof of man’s impact on our environment. They claim part of the human impact is greater volatility in our climate. Dr. Tim Ball says that’s nonsense. Ball is a former professor of climatology at the University of Winnipeg and is one of the leading scientific voices challenging the climate-change movement. Ball says the events we’re seeing are cyclical and are actually the start of a cooling trend for our climate. He explains how winds from the ...

MISA researchers from SARDI have isolated and evaluated a ‘super strain’ of a native microalgae species that could form the basis of a local biofuels industry. This breakthrough in biodiscovery comes after six years of ‘bioprospecting’ across thousands of kilometres of the State and into the waters of the Great Australian Bight by SARDI researchers followed by laboratory and small-scale outdoor raceway trials. The success in finding this particular strain of microalgae among the hundreds of microalgal species and strains evaluated has given South Australia a head start as research into third generation biofuels advances to the next level.

Summary: The FBI's shut-down of temporary DNS servers will rid the internet of those infected by DNSChanger, and it will be a better place because of it. commentary Six thousand Australians infected with DNSChanger malware are set to be cut off from the internet on Monday, when the FBI shuts down the temporary servers that are keeping them online. In my opinion, they deserve to lose the privilege to connect to the internet. DNSChanger tricks computers into connecting to rogue DNS servers, which point certain domain names to IP addresses of their choosing. For instance, these rogue DNS servers could point Google.com to a malicious site without the user knowing. Those infected with ...

SAN FRANCISCO, July 3 (Xinhua) -- Google on Tuesday announced to shut down five products which are not core to its business. Among the five products to be axed, the most notable are iGoogle, the search giant's personalized homepage service and Google Video. iGoogle will be axed on Nov. 1, 2013, giving users 16 months to adjust or export their data, said Google in its official blog. It said that with today's web and mobile apps, the need for iGoogle has eroded over time. For Google Video, which stopped taking uploads in May 2009, its remaining hosted content will be moved to YouTube this summer and users need to migrate, delete or downloaded their content before Aug.20.

WASHINGTON — The more we study animals, the less special we may seem. Baboons can distinguish between written words and gibberish. Monkeys seem to be able to do multiplication. Apes can delay instant gratification longer than a human child can. They plan ahead. They make war and peace. They show empathy. They share. "It's not a question of whether they think -- it's how they think," said Duke University scientist Brian Hare. Now scientists wonder if apes are capable of thinking about what other apes are thinking. The evidence that animals are more intelligent and more social than we thought seems to grow each year, especially when it comes to primates. It's an ...

“The most exciting phrase to hear in science, the one that heralds new discoveries, is not ‘Eureka!’, but ‘That’s funny’,” author and chemistry professor, Isaac Asimov, once observed.? Many important scientific concepts owe their discovery to pure chance...or even dumb luck. The award for the most famous accidental finding goes to Sir Alexander Fleming. Fleming, as part of his on-going research, would grow bacteria cultures in Petri dishes. But in the summer of 1928, Fleming got a little careless. He left a few of his Petri dishes exposed to the air, and then went on vacation. When he returned from vacation, he happened to notice that one of the Petri ...
