At what temperature does water have to freeze? The answer: Not necessarily at zero degrees Celsius (32 degrees Fahrenheit).Water can exist in liquid form well below this threshold, notably in a so-called "supercooled" state that is well into the minus zone.The reason: ...

Evolution Speeding Up

Researchers at the University of Utah have published a report stating that human evolution has accelerated over the last 10,000 years. (December 10, 2007) The study indicates that environmental differences are the major determinant of genetic mutation, and suggests that people in ...
Bogus science can be found in large quantities wherever one cares to look. In 1989, Martin Fleischmann and Stanley Pons, electrochemists at the University of Utah, created a worldwide stir by announcing they had developed cold fusion - the fusion of atomic ...
While still in its infancy and primitive, even crude, two grids of 16 microelectrodes implanted atop the brain of a volunteer with severe epileptic seizures are somewhat successfully decoding brain signals into a small set of words, thanks to work out of ...
In an effort to unlock the speech capacity in patients who cannot speak because of so-called "locked-in syndrome," University of Utah researchers have successfully demonstrated that they can translate brain signals into words using electrode grids placed beneath the skull. Using two ...

'Grandmother Hypothesis' Takes a Hit

Grandma may not be as important as we thought--at least when it comes to evolution. The evolutionary biologist William Hamilton initially proposed the idea in a 1966 paper that built on the theoretical work of George Williams and Peter Medawar. These researchers ...
How are Tibetans able to thrive in the oxygen-thin high altitudes of the Tibet highlands when non-residents find the environment hard to endure? Thousands of years of natural selection have allowed Tibetan highlanders to evolve 10 unique oxygen-processing genes that help them ...

Science Education Web Sites

In this issue, we announce the first of 12 winners of a competition for web sites that best promote science education. Each month this year, Science will publish an essay by the creators of a winning Web site that describes their online ...
Genetic evidence suggests that early humans came close to extinction about 1 million years ago, according to a new study by researchers at the University of Utah in Salt Lake City.. In other news of the ancient past, the Associated Press reported ...

Gators Breathe Like Birds

Did Dinosaur's Ancestors Inhale their Way to Dominance? "The real importance of this air-flow discovery in gators is it may explain the turnover in fauna between the Permian and the Triassic, with the synapsids losing their dominance and being supplanted by these ...
