Gorilla genome sheds new light on human evolution

LONDON (Reuters) - Scientists have sequenced the genome of the gorilla, the last great ape to have its genes decoded, and say it gives new insights into differences between the apes and humans - including their ability to produce competitive sperm. While confirming that our closest relative is the chimpanzee, the research also shows that around 15 percent of the human gene map resembles the...

By contrast, the iPad 2 offers a 1024x768 screen. The new version of the popular tablet, still with a 9.7-inch screen, also...

Biodegradable transistors -- made from us

Silicon, a semi-conducting element, is the basis of most modern technology, including cellular phones and computers. But according to Tel Aviv University researchers, this material is quickly becoming outdated in an industry producing ever-smaller products that are less harmful to the environment.

Do moons of gas giants affect the habitable zone?

(PhysOrg.com) -- If you aren’t familiar with the Drake Equation, or how it may actually apply to exomoons, continue reading to learn more about the famous equation. Additionally, what conditions could make a habitable moon like Pandora as depicted in Avatar, or the forest Moon of Endor as seen in Return of the Jedi?

First large-scale analysis of 'soft' censorship of social media in China

Researchers in Carnegie Mellon University's School of Computer Science analyzed millions of Chinese microblogs, or "weibos," to uncover a set of politically sensitive terms that draw the attention of Chinese censors. Individual messages containing the terms were often deleted at rates that could vary based on current events or geography.

Internet censorship revealed through the haze of malware pollution

On a January evening in 2011, Egypt – with a population of 80 million, including 23 million Internet users – vanished from cyberspace after its government ordered an Internet blackout amidst anti-government protests that led to the ouster of Egyptian President Hosni Mubarak. The following month, the Libyan government, also under siege, imposed an Internet "curfew" before completely...

Market exchange rules responsible for wealth concentration

Two Brazilian physicists have shown that wealth concentration invariably stems from a particular type of market exchange rules – where agents cannot receive more income than their own capital. The authors concluded that maximum inequalities ensue from free markets, which are governed by such seemingly fair rules.

NIST releases Gulf of Mexico crude oil reference material

The National Institute of Standards and Technology (NIST) has released a new certified reference material to support the federal government's Natural Resources Damage Assessment (NRDA) in the wake of the April 2010 Deepwater Horizon oil spill 40 miles off the Louisiana coast. The new Standard Reference Material, Gulf of Mexico Crude Oil" (SRM 2779), will be used as a quality control material for...
