Mysterious 'neural noise' actually primes brain for peak performance

...iences have blazed a new path to understanding our gray matter. The traditional approach has assumed the brain uses the same method computation in general had used up until the mid-80s: You see an image and you relate that image to one stored in your head. But the reality of the cranial world seems to be ...

Human preference for other species could determine whether they survive

...and elephants, for example, are black and white or gray but are highly preferred by humans. Millions of insects and the countless slimy invertebrates that occupy the oceans are likely not as lucky, Stokes said. "The work pretty conclusively shows there is a large difference of appeal among organisms, ...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

In men, trichomoniasis is most common in the urethra; however, infected men ofte...

Lithium builds gray matter in bipolar brains, UCLA study shows

...ment for bipolar disorder, increases the amount of gray matter in the brains of patients with the illness....ents not on lithium, they found that the volume of gray matter in the brains of those on lithium was as much as 15 percent higher in areas that are critical...

Researchers identify gene involved in dog size

...t includes domestic dogs diverged from that of the gray wolf more than 15,000 years ago. Due to selective breeding by humans throughout history, dogs today exhibit an extremely wide range of body types and behaviors. In fact, dogs exhibit the greatest diversity in body size of any mammalian species. In...

Researchers publish first marsupial genome sequence

...o generate the high-quality genome sequence of the gray short-tailed, South American opossum, Monodelphis domestica, began in 2003 and cost approximately $25 million. The sequencing work was funded by the National Human Genome Research Institute (NHGRI), part of the NIH, and carried out at the Broad Insti...
