Discovery of brain's memory 'buffer' in single cells

Individual nerve cells in the front part of the brain can hold traces of memories on their own for as long as a minute and possibly longer, researchers at UT Southwestern Medical Center have found.

Can't help being the life of the party?

Maybe you were just born that way. Researchers from Harvard University and the University of California, San Diego have found that our place in a social network is influenced in part by our genes, according to new findings published in the Proceedings of the National Academy of Sciences.

Statins may treat cerebral cavernous malformation

In a finding that could save thousands of lives a year, University of Utah School of Medicine researchers have shown that a blood vessel disorder leading to unpredictable, sometimes fatal, hemorrhagic strokes, seizures, paralysis or other problems is treatable with the same statin drugs that millions of people take to control high cholesterol.

Scientists discover new class of small RNAs

Researchers at Cold Spring Harbor Laboratory (CSHL) announced today the discovery of a new class of small RNAs. At the same time, they reported that their discovery suggests the presence of a strikingly novel biochemical pathway for RNA processing in which these and possibly other small RNAs are produced.

Genetic testing may not lead to demand for 'designer babies'

A new study by researchers at NYU Langone Medical Center found a high desire for additional genetic testing among consumers for life altering and threatening medical conditions including mental retardation, blindness, deafness, cancer, heart disease, dwarfism and shortened lifespan from death by 5 years of age.

Although our genetics differ significantly, we all look alike...

The genetic variation within a species can be significant, but very little of that variation results in clear differences in morphology or other phenotypes.

Scientists discover a compound that gets rid of excess cholesterol

New research by scientists in the United States carried out in mice has revealed a compound that releases excessive cholesterol accumulated inside cells.
