Better School Buildings Mean Better Student Performance, Says Architect

High performance schools integrate the best in today's design strategies and building technologies. Even better, they make a difference in the way children learn. Research has shown that better buildings produce better student performance, reduce operating costs and increase average daily attendance. They also are more likely to maintain teacher satisfaction and retention and reduce liability exposure.

Novel salamander robot crawls its way up the evolutionary ladder

A group of European researchers has developed a spinal cord model of the salamander and implemented it in a novel amphibious salamander-like robot. The robot changes its speed and gait in response to simple electrical signals, suggesting that the distributed neural system in the spinal cord holds the key to vertebrates’ complex locomotor capabilities.The EPFL Salamander Robot walks down to the waters of Lake Geneva.

Canadian stroke victims more likely to die on weekends

Patients admitted to hospitals for ischemic stroke on weekends had a higher risk of dying than patients admitted during the week, in a Canadian study published in Stroke: Journal of the American Heart Association.

A "weekend effect" has been previously documented when looking at other conditions such as cancer and pulmonary embolism; however, little is known of its impact on stroke death.

Physiological Evidence of Subliminal Advertising

University College London researchers have found the first physiological evidence that invisible subliminal images do attract the brain's attention on a subconscious level. The wider implication for the study, published in Current Biology, is that techniques such as subliminal advertising, now banned in the UK but still legal in the USA, certainly do leave their mark on the brain.

UGA research shows rats are capable of reflecting on mental processes

Let’s say a college student enters a classroom to take a test. She probably already has an idea how she will do—knowledge available before she actually takes out a pencil. But do animals possess the same ability to think about what they know or don’t know?

Creating Jack's Beanstalk

Something about normal, run-of-the-mill plants limits their reach upward. There's been no way to create that magical beanstalk in the fairy tales but no one knows why. For more than a century, scientists have tried to find out which part of the plant both drives and curbs growth: is it a shoot's outer waxy layer? Its inner layer studded with chloroplasts? Or the vascular system that moves nutrients and water? The answer could have great implications for modern agriculture, which desires a modern magical bean or two.

How do people feel about nanotechnology?

David Houle touched on this in his Berkeley and Nanotechnology article and now lots of other people are wondering the same thing. Will it be regarded as hazardous materials or tools of big corporate evildoers or as benevolent forces for change in society?

Omega-3s boost grey matter, findings may explain why omega-3s seem to improve mood

Omega-3 fatty acids, found in fatty fish like salmon, are associated with increased grey matter volume in areas of the brain commonly linked to mood and behavior according to a University of Pittsburgh study.

Findings will be presented today by Sarah M. Conklin, Ph.D., postdoctoral scholar at the Cardiovascular Behavioral Medicine Program in the department of psychiatry at the University of Pittsburgh, at the American Psychosomatic Society’s Annual Meeting, held in Budapest, Hungary.

Researchers discover gene essential to cerebellum formation

Scientists have identified a molecular switch that causes the differentiation of neurons in the cerebellum, a part of the brain that helps to regulate motor functions.

For easy tasks, brain preps and decides together

A Georgia Tech researcher has discovered that for tasks involving spatial processing, preparing for the task and performing it are not two separate brain processes, but one – at least when there are a small number of actions to choose from. The research appears online in the journal Brain Research.

Genetic testing for substance abuse raises hope ... and concern

Genetic tests using blood samples already are used to diagnose some diseases and even personalize treatment.

Now it is possible to develop similar tests that reveal a person's potential to become dependent on nicotine or marijuana or have antisocial personality disorder, University of Iowa researchers report online March 6 in the American Journal of Medical Genetics.

Does Tooth-brushing Cause Epilepsy Seizures?

Tooth-brushing may trigger seizures in certain people with epilepsy, and researchers say lesions in a specific part of the brain may be a cause in some people, according to an article published in the March 6, 2007, issue of Neurology®, the scientific journal of the American Academy of Neurology.

Selectivity Is The Ultimate Aphrodisiac

Speed daters who romantically desired most of their potential partners were rejected quickly and overwhelmingly, according to a new Northwestern University study.

Hypoglycemic coma treatment causes brain damage, research says

Brain damage that was thought to be caused by hypoglycemic coma actually occurs when glucose is administered to treat the coma, according to a study in rodents led by researchers at the San Francisco VA Medical Center.

The results are surprising, say the authors, and may be of clinical significance for the treatment of diabetics in hypoglycemic coma, though they caution that the results cannot be immediately extrapolated to humans.

When It Comes To Brains, Size Doesn't Always Matter

As we have seen, penis size matters to female mice and sword size matters to female swordfish but brain size in humans barely gets noticed at all. It's what you do with it that counts.
