Education was becoming a no-brainer, some people at Harvard’s Graduate School of Education (HGSE) complained.

Kurt Fischer and his colleagues looked at the revolution in brain scanning, genetics, and other biological technologies and decided that most teachers and students weren’t getting much benefit from them. Brain scans are now available to watch what’s going on when someone is learning — or not learning. Finding genes that are involved in leaning disabilities is a hot area. Why, they asked, aren’t the powers of such technologies helping teachers in classrooms?

A thin film of carbon polymer which conducts electricity and runs on solar power could be the basis for a revolution in the way we light our homes and design clothes.

An international research project has begun that could help bring to mass-market organic light emitting devices (OLEDs), which could have far reaching technological implications and cut the cost of lighting by billion of pounds each year.

In the U.S. more than $20 billion was spent on dietary supplements in 2005. Over $7 billion was spent on plant-based herbal dietary supplements such as grape seed extract, St. John's wort, ginseng and biloba extract.

Researcher Dr. Susanne Mertens-Talcott of Texas A&M University is looking into how useful plant-based phytochemicals, including antioxidants and herbal supplements, can be in the promotion of health and prevention of chronic diseases.

"My overall goal is to find out more about the safety and efficacy of phytochemical dietary supplements," she said. Because these items are already popular with consumers, "we need to follow up with research. We know very little about (dose) recommendations and how safe (they are)."

Raven, the mobile surgical robot developed by the University of Washington, is going into the Atlantic Ocean to participate in NASA's mission to submerge a surgeon and robotic gear in a simulated spaceship.

For 12 days the surgical robotic system will be put through its paces in an underwater capsule that mimics conditions in a space shuttle. Surgeons back in Seattle will guide its movements.

Changing one's diet to lose weight is often difficult. There may be physical and psychological effects from a changed diet that reduce the chances for success. With nearly 65% of the adult population currently classified as overweight or obese and with calorically dense foods high in fat and carbohydrates readily available, investigating those factors that contribute to dieting failures is an important effort.

Researchers found that mice withdrawn from high-fat or high-carbohydrates diets became anxious and showed changes in their brains indicating higher stress levels.

Where there is cigarette smoking there is probably misuse of alcohol too, according to a study by Yale School of Medicine researchers in the Archives of Internal Medicine.

"This means cigarette smoking status can be used as a clinical indicator for alcohol misuse, which presents an opportunity for intervention," said the principal investigator, Sherry McKee, assistant professor of psychiatry.

Penn State researchers will soon provide he first demonstration of a fundamentally new method for measuring a particular quantum property of individual atoms. "This method allows us to directly and precisely measure the phase shifts that result when ultracold atoms collide, in a way that is independent of the accuracy-limiting density of the atoms," says Kurt Gibble, an associate professor of physics and principal investigator of the Penn State University research team that developed the method.

Turning a greenhouse gas into a clean energy fuel is the Holy Grail of energy research. UC San Diego chemists have a prototype they think is an important milestone.

Their device captures energy from the sun, converts it to electrical energy and "splits" carbon dioxide into carbon monoxide (CO) and oxygen.

Obviously carbon monoxide in and of itself is not great either but millions of pounds of it are used each year to manufacture chemicals including detergents and plastics. It can also be converted into liquid fuel.

In the children’s game "red light green light," winners are able to stop, and take off running again, more quickly than their comrades. New research reveals that a similar race goes on in our brains, with impulse control being the big winner.

"The research provides new insights into how the brain controls movements, which helps explain the impulsivity of people with attention deficit and hyperactivity disorder," study co-author Jeffrey Schall, E. Bronson Professor of Neuroscience at Vanderbilt University, said.

Scientists using one of the nation's newest and most capable research aircraft are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. The plumes are among the largest such events on Earth, so great in scope that scientists believe they might affect clouds and weather across thousands of miles while interacting with the sun's radiation and playing a role in global climate.
