Researchers at MIT's Picower Institute for Learning and Memory have corrected key symptoms of mental retardation and autism in mice. The report in Neuron also indicates that a certain class of drugs…

The seemingly inefficient way our bodies replace worn-out cells is a defense against cancer, according to new research. Having the neighboring cell just split into two identical daughter cells would…

UC Davis researchers have dated the earliest step in the formation of the solar system -- when microscopic interstellar dust coalesced into mountain-sized chunks of rock -- to 4,568 million years ago…

Heart attacks among cigarette smokers may have less to do with tobacco than genetics. A common defect in a gene controlling cholesterol metabolism boosts smokers’ risk of an early heart attack,…

A research team led by Dr. Pierre Moffatt of the Shriners Hospital for Children in Montreal and McGill University’s Department of Human Genetics has uncovered the molecular mechanism by which the…

Twelve healthy subjects in their 60s and 70s showed a different pattern of brain activations during thirst and satiation than did 10 healthy subjects in their 20s who drank the same amounts and…

Chemical engineering researchers at the University of Arkansas have investigated supercritical methanol as a method of converting chicken fat into biodiesel fuel. The new study also successfully…

Mathematicians from the University of Exeter say they have solved the mystery of traffic jams by developing a model to show how major delays occur on our roads, with no apparent cause. Many traffic…

A new study of twins indicates that the genetic foundation for the brain’s ability to recognize faces and places is much stronger than for other objects, such as words. The results, which appear in…

A research team at Maryland's A. James Clark School of Engineering comprised of Professor Christopher Davis, Research Scientist Igor Smolyaninov, and graduate student Yu-Ju Hung, has used plasmon…

Scientists long have focused on how climate and vegetation allowed human ancestors to evolve in Africa. Now, University of Utah geologists are calling renewed attention to the idea that ground…

A Virginia Commonwealth University Life Sciences Survey is the first poll to reflect the discovery reported internationally in November that human skin cells can be used to create stem cells or their…

Viticulture, the growing of grapes Vitis vinifera, chiefly to make wine, is an ancient form of agriculture, dating as far back as the Neolithic and Early Bronze Ages. We have a detailed…

In the world of commercial materials, lighter and cheaper is better - especially when coupled with superior strength and special properties such as a material's ability to remember its original shape…

Do polls reflect who people will vote for or who they would like to be perceived as voting for? A new national study of voters who say they might vote in Democratic primaries (participants were not…

A cosmic explosion that seems to have occurred thousands of light-years from the nearest galaxy-sized collection of stars, gas, and dust has puzzled astronomers. This "shot in the dark" is surprising…

No human can survive longer than a few minutes underwater, and even a well-trained Olympic swimmer needs frequent gulps of air. Our brains need a constant supply of oxygen, particularly during…

People suffering from chronic mental or physical disabilities should not resort to a dolphin "healing" experience, warn two researchers from Emory University. Lori Marino, senior lecturer in the…

On June 30, 1908 a stunning explosion rocked the forest near the Tunguska river in Siberia. Estimates were that an asteroid exploded in the air a few kilometers above the earth's surface with a…
