The same genes that are chemically altered during normal cell differentiation, as well as when normal cells become cancer cells, are also changed in stem cells that scientists derive from adult cells, according to new research from Johns Hopkins and Harvard.
Although genetically identical to the mature body cells from which they are derived, induced pluripotent [...]

The loss of a gene through deletion of genetic material on chromosome 15 is associated with significant abnormalities in learning and behavior, said a consortium of researchers led by Baylor College of Medicine in a report that appears online today in the journal Nature Genetics.
"This research goes about 95 percent of the way to pinning [...]

The odds triple for premature child delivery pregnant women with a history of depression who used psychiatric medication, according to a new study.
Researchers at the University of Washington, University of Michigan and Michigan State University found that a combination of medication use and depression — either before or during pregnancy — was strongly linked to [...]

Men whose prostate specific antigen (PSA) rise within 18 months of radiotherapy are more likely to develop spread and die of their disease, according to an international study led by Fox Chase Cancer Center radiation oncologist Mark K. Buyyounouski, M.D., M.S. and presented today at the annual meeting of the American Society for Radiation Oncology [...]

A study by six researchers, including a University of Colorado at Boulder associate professor and his former doctoral student, shows that amputees who use running-specific prosthetic legs have no performance advantage over counterparts who use their biological legs.
A debate on the matter was spurred when Oscar Pistorius, a bilateral amputee, was barred from the 400-meter [...]

Suppose you want to build a computer that operates like the brain of a mammal. How hard could it be? After all, there are supercomputers that can decode the human genome, play chess and calculate prime numbers out to 13 million digits.
But University of Wisconsin-Madison research psychiatrist Giulio Tononi, who was recently selected to take [...]

Pomegranate peel left over from production of the juice renowned for its potential health benefits can make a nutritious feed supplement for cattle, researchers in Israel report. The peel packs some of the weight-boosting and health-enhancing effects of antibiotics and hormones without the detrimental effects, and researchers say it may yield meat with higher levels [...]

Scientists are looking to outer space for help in their attempt to prevent new outbreaks of the tropical disease schistosomiasis in southern China.
Once the Three Gorges Dam is fully operational, researchers plan to use satellite data from space to determine whether changing water conditions in Poyang Lake, China’s largest freshwater lake, create [...]

Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body.
The finding, reported online in advance of publication in Nature by University of California, Berkeley, researchers, indicates that the same [...]
