OHSU researchers study physical and mental impacts of exercise on the brain
OHSU researchers and other collaborators have found that exercise results in brain development (specifically blood vessel development in the brain.) The researchers have also found that exercise causes a subject to be more mentally engaged.

Reading the brain
Children, adolescents and adults use their brains differently during a simple reading task, according to research at Washington University School of Medicine in St.

Don't always believe what you see, suggests study on false memories
People can easily be swayed into believing that they have seen something they never actually did see, say researchers at Ohio State University.

Vital sign device improves resuscitation monitoring
A small device can give doctors the

Yerkes researchers discover natural brain chemical reduces effects of cocaine
Researchers at the Yerkes National Primate Research Center at Emory University, have shown that CART peptide, a chemical that occurs naturally in both the rodent and human brain, reduces some effects of cocaine when additional amounts are administered to the region of the brain that is associated with reward and addiction.

Genetic aberration helps explain variation in cystic fibrosis
At the annual meeting of the Americal Society for Human Genetics in Los Angeles, Hopkins researchers will reveal the existence of specific short repeats of particular genetic building blocks in the gene at the root of cystic fibrosis, an inherited and often fatal lung disease.

Diet may improve cognition, slow aging, and help protect against cosmic radiation
Eating certain foods can help protect you from heart disease, some types of cancers and other illnesses.

Exercise has a more powerful impact on the brain than previously thought
Scientists are learning that exercise has a much more direct and powerful impact on the brain than previously believed -- an exciting discovery that may lead to safer and more effective approaches to preventing and treating a variety of brain injuries and diseases, from spinal cord injuries to depression.

Diabetes management improves when patients, doctors agree on treatment goals, UMHS study finds
People with diabetes who agree with their physician's treatment goals and strategies were more likely to be successful at managing their condition, but few patients agree with their doctor's top three goals and strategies, researchers at the University of Michigan Health System report.

Several commonly used pesticides are toxic to mitochondria in laboratory experiments
Scientists at Emory University School of Medicine have found in laboratory experiments that several commonly used pesticides are just as toxic or even more toxic to the mitochondria of cells than the pesticide rotenone, which already has been implicated in the development of Parkinson's disease.

Emory scientists use enzymes to enhance regeneration of damaged peripheral nerves in mice
Scientists at Emory University School of Medicine were able to enhance significantly the re-growth of damaged peripheral nerves in mice by treating them with enzymes that counteracted a growth-blocking mechanism.

Scientists find brain areas activated in true versus false memories
New studies of false memories show that what happens in the brain when memories are established can be as important to the development of false memories as what happens during memory retrieval.

Scientists map maturation of the human brain
For the first time, scientists have mapped the progressive maturation of the human brain in childhood and adolescence.

Region of chromosome 1 important in blood pressure regulation
Scientists are closing in on genetic contributors to high blood pressure and other causes of heart and cardiovascular disease.
