Scientists uncover new clues about brain function in human behavior

...This may be the first study to identify functional disturbances in a brain pathway associated with abnormal social behavior caused by a genetic disorder," said NIMH Director Thomas R. Insel, M.D. In this study, investigators used functional brain imaging (fMRI) to study the amygdala and structures linked to it i...

A novel method to measure circadian cycles

...een large populations for genetically linked sleep disturbances such as advanced and delayed sleep phase syndromes. They may also use this test to hone in on the genetic mechanism responsible for such conditions. Outside the realm of medicine, future genetic studies of circadian rhythm may exploit the method deve...

Discovering an ecosystem beneath a collapsed Antarctic ice shelf

...as opened the pristine chemical-based ecosystem to disturbances and debris that have already begun to bury the delicate mats and mollusks established within the underwater environment. He added that there may be a sense of urgency to investigate the unusual seafloor ecology below the Larsen shelf because of the l...

Stem cell therapy successfully treats heart attack in animals

...raditionally result from a heart attack, including disturbances of heart rhythm that can lead to sudden cardiac death, and decreased muscle pumping function that can lead to congestive heart failure." The researchers are using a special kind of stem cell in an early stage of development, called adult mesenchymal...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...uld polar caps continue receding, hypothetical new disturbances on the northern ocean such as energy exploitation, fishing and shipping. The research compares species distribution in the shelf, slope and deep sea regions (the deep sea is generally agreed to begin at 1,000 meters). Investigations of the seawater'...

U. Iowa researchers improve Huntington's disease symptoms in mice

...amage leads to the movement disorders, psychiatric disturbances and cognitive decline that characterize this disease. "Many of the current approaches aimed at treating HD are indirect and target the symptoms of the disease. RNA interference gives us the first opportunity to attack the fundamental problem and red...
