For decades, frustrated parents and teachers have barked at fidgety children with ADHD to “Sit still and concentrate!” But new research shows that if you want ADHD kids to learn, you have to let them squirm. The foot-tapping, leg-swinging and chair-scooting movements of children with attention-deficit/hyperactivity disorder are actually vital to how they remember information and work out complex cognitive tasks....

A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels....

Many years of research have shown that for students from lower-income families, standardized test scores and other measures of academic success tend to lag behind those of wealthier students. Well now a new study offers another dimension to this so-called “achievement gap”After imaging the brains of high- and low-income students, they found that the higher-income students had thicker brain cortex in areas associated with visual perception and knowledge accumulation....

According to a large study just published in the Journal of Autism and Developmental Disorders, there's no correlation between brain anatomy and self-reported autistic traits.
Dutch researchers P. Cedric M. P. Koolschijn and colleagues looked at two samples of young Dutch adults: an 'exploration' sample of 204, and a separate 'validation' group of 304 individuals.
Most of the participants did not have autism. The researchers looked for associations between various aspects of brain ... Read more »

If a time machine was available, would it be right to kill Adolf Hitler when he was still a young Austrian artist to prevent World War II and save millions of lives? Should a police officer torture an alleged bomber to find hidden explosives that could kill many people at a local cafe? When faced with such dilemmas, men are typically more willing to accept harmful actions for the sake of the greater good than women. For example, women would be less likely to support the killing of a young Hitler........ Read more »

Ever hear that old saying an apple a day keeps the Doctor away? Well it might have the right idea, just the wrong person.

We know that hormones affect who we are, even when we aren’t aware of it.

However, new research shows that women seek a greater variety of products and services, specifically when they are ovulating.... Read more »

About five million people in the US suffer from heart failure, and approximately half of them die within five years of being diagnosed. Only about 2,500 hundred people a year receive a heart transplant – the treatment of last resort. A new heart can be life-saving, but it is also life-changing. Even under the best conditions, the surgery is complex, and recovery carries a heavy physical and emotional burden.

This boy may be influencing who he will marry when he grows up. Photo by Orrling at Wikimedia Commons.Animals (including humans) are swarming with microorganisms both on and in our bodies. Humans harbor so many different microorganisms that we have over 150 times more microbial genes than mammalian genes, and it is reasonable to suspect that this scenario is similar for most animals. But before you run to soak in a tub of hand sanitizer, you should realize that many of these microorganisms are a........ Read more »

Childhood obesity affects more than double the amount of children it did 30 years ago, according to the Centers for Disease Control and Prevention(CDC). To figure out why the rate is increasing researchers studied the relationship between parents and their obese children to determine how to improve pediatric health. The study actually reveals how poorly parents rate their own child’s weight issues — at least until they reach extreme levels of obesity.... Read more »

When the government first changed policy to require ethanol in gasoline, we were told it would reduce our carbon footprint. Then food prices rose significantly and corn in particular saw the largest price rise. This was because corn is a staple in production of almost any other food from eggs to beef, but the policy made environmental sense. Well it made sense, until you found out that the new government policy also took into account people eating less.... Read more »

Sometimes being too focused on a task is not a good thing. During tasks that require our attention, we might become so engrossed in what we are doing that we fail to notice there is a better way to get the job done. For example, let’s say you are coming out of a New York City subway one late afternoon and you want to find out which way is west. You might begin to scan street signs and then suddenly realize that you could just look for the setting sun.... Read more »
