Humans and their closest relatives, chimpanzees, may be more different than geneticists have realised.
Previously, scientists have estimated that humans and chimps differ in about 1.5 per cent of the DNA letters that spell out their genomes. However, these estimates have been based on studies of only small subsets of the two genomes, because the chimp genome has not been sequenced precisely enough to allow a large-scale, base-by-base comparison.
Looking to feather its market cap, IPO-bound Google may add a colorful new feather to its search-engine cap as the de facto arbiter in the fame game.
Physics and computer-science researchers at Clarkson University have used the popular search engine to establish a precise mathematical definition of fame, both in the sciences and the world at large.
The steep rise in some cancers of the gullet in developed countries could be explained by the massive increase in the consumption of fizzy soft drinks, suggests a new study.
The volume of carbonated soft drinks downed in the US has increased nearly five-fold in the 50 years, while in the last 25 years rates of esophageal adenocarcinoma have rocketed by nearly six-fold in white males, the group with the highest soft drink consumption.
A fundamental law of classical physics has been broken by two teams of physicists who have linked particles of light together in a way that enhances its normal properties.
Their method for 'entangling' photons could one day allow information to be more densely crammed and read from CDs and other memory devices.
It took Adam Arkin and David Schaffer just $200,000 and a grad student to develop a potential treatment for AIDS. And that scares them.
