A new paper claims that when study participants ate alone, the food tasted better and they ate more if they could see themselves reflected in a mirror. This was true of both elderly and young adult participants.

Exercise can be intimidating. Like not calling your grandmother because you don't want to be berated for not calling for so long, it can be hard to stop. But even if you only exercise once, it can have positive effects on mood, memory, attention, motor/reaction times, and even creativity. Understanding the immediate effects of a single bout of exercise is the first step to understanding how the positive effects of exercise may accrue over time to cause long-lasting changes in select brain circuits.

But there are reasons why some people are great in The Division and you die in the Dark Zone within seconds after meeting another player. Basically, they learned shortcuts and before they ever met you, they warmed up.

Adolescents with autism spectrum disorder (ASD) use 400 percent more emergency-department services than peers without autism, which puts more strain on an over-burdened health care system. It may be that they need better access to primary care.

Some people have an extreme fear of spiders or other objects while others have breathing difficulties and accelerated heart beat in small rooms or large gatherings of people. Some anxiety attacks occur for no apparent cause. Some patients suffer from the detrimental impacts on their everyday lives, they have problems at work and withdraw from social contacts.

A new study believes that football clubs which focus too much on physical attributes risk overlooking future stars. Does this mean that with the correct cognitive behavior you could outrun Usain Bolt?
