The results, say researchers from the University of California, San Diego and the Salk Institute for Biological Studies, lend support to the hypothesis that cross-activation of adjacent brain regions is the mechanism underlying synesthesia. "We specifically designe...

...e to perform better on memory tests. The studies, say the scientists, suggest that even people who are genetically predisposed to the disease may be able to delay it by boosting their DHA intake. Omega-3 fatty acids, typically deficient in the American diet, are essential for human health. DHA in part...

Researchers trace evolution to relatively simple genetic changes

..." Ordinarily, "you wouldn't look at that gene and say it's an obvious candidate for dramatically changing skeletal structures in wild animals that end up completely viable and healthy,' he said. "Eda gene mutations cause a disease in humans, but not in the fish. So this is the first time mutations have ...

The work -- done using advanced molecular tools with grape-cell cultures and the target enzyme for new anti-cancer strategies -- helps to identify which flavonoids in grapes and red wine a...

Sea skate experiment sheds light on human cell transport

... ability to transport glucose. Goldstein and Musch say their findings could explain the problem. People with type 1 diabetes don't produce insulin. Without that hormone, vesicles aren't inserted into cell membranes and glucose can't be moved between cells. And when channels are blocked, damaged cells ca...

Autism linked to mirror neuron dysfunction

But in autistic individuals, say researchers from the University of California, San Diego, the brain circuits that enable people to perceive and understand the actions of others do not behave in the usual way.

New findings about protection against pneumococcal disease

... these cells did not develop immunity. "Textbooks say that naturally-acquired protection against pneumococcal disease depends on the development of antibody against the capsule of the bacterium," says Malley, who is also an assistant professor in pediatrics at Harvard Medical School. "We were surprised ...

Solving sleep problems helps epileptic children

Characterized at its extreme by physical convulsions, epilepsy has long been thought to cause excitability and contrariness in children. But UF researcher...

'Free-for-all' illegal logging of mahogany in Peruvian parks, says Duke-based monitoring group

"In general, it is a tree that is not easy to regenerate," Martinez said. "And the loggers go for the mature trees,...

Gene mutation protecting against malaria linked to prostate cancer incidence in African-American men

...roximately the same time, which is not surprising, say the researchers, since chemokines have not been linked to the formation of cancer, just to its spread through angiogenesis. Once the mice's tumors formed and began to grow, however, the story was very different. In mice bred to have the mutation, an...

...or most patients with AMD and RP," the researchers say in their paper. "However, if one could bypass the photoreceptors and directly stimulate the inner retina with visual signals, one might be able to restore some degree of sight." To that end, the researchers plan to directly stimulate the layer undern...
