Unconscious mind can detect a liar -- even when the conscious mind fails

Posted: 24 Mar 2014 07:45 AM PDT

When it comes to detecting deceit, your automatic associations may be more accurate than conscious thought in pegging truth-tellers and liars, according to research. The findings suggest that conscious awareness may hinder our ability to detect whether someone is lying, perhaps because we tend to seek out behaviors that are supposedly stereotypical of liars, like averted eyes or fidgeting. But those behaviors may not be all that indicative of an untrustworthy person.

Not only is she thinner than you, her muscles work better, too: Role of muscle function in maintaining weight

Posted: 20 Mar 2014 02:34 PM PDT

Researchers examined how muscle physiology effects leanness. They found that while rats with 'lean genes' burned a similar amount of calories at rest as those with 'obese genes,' the muscles of lean rats burned much more energy during mild activity. The research sheds new light on the role of muscle function and metabolism in maintaining weight.

3-D model links facial features and DNA

DNA can already tell us the sex and ancestry of unknown individuals, but now an international team of researchers is beginning to connect genetics with facial features, degrees of femininity and racial admixture. The researchers looked at both actual physical face shape and genetic markers of face shape.

To understand how obesity develops, researchers used state-of-the-art technology to analyze the accumulation of fat in the body at the cellular level, and according to their new findings, nutrition is not the most important factor driving obesity. The researchers offer insight into the development of obesity and are now creating a platform to develop new therapies and technologies to prevent or even reverse fat gain.

Can 'love hormone' protect against addiction?

Posted: 20 Mar 2014 07:05 AM PDT

Addictive behavior such as drug and alcohol abuse could be associated with poor development of the so-called "love hormone" system in our bodies during early childhood, according to researchers. The groundbreaking idea has resulted from a review of worldwide research into oxytocin, known as the "love hormone" or "bonding drug" because of its important role in enhancing social interactions, maternal behavior and partnership.

Fake laughter doesn't fool the brain, research reveals

Posted: 19 Mar 2014 07:25 PM PDT

As the world celebrates International Day of Happiness today (Thursday, 20 March), can we tell whether people are truly happy just from their laugh? "During our study, when participants heard a laugh that was posed, they activated regions of the brain associated with mentalizing in an attempt to understand the other person's emotional and mental state," the authors state.

Climatologists offer explanation for widening of Earth's tropical belt

Posted: 18 Mar 2014 08:38 AM PDT

Climatologists posit that the recent widening of the tropical belt is primarily caused by multi-decadal sea surface temperature variability in the Pacific Ocean. This variability includes the Pacific Decadal Oscillation (a long-lived El Niño-like pattern of Pacific climate variability) and anthropogenic pollutants, which act to modify the Pacific Decadal Oscillation. Until now there was no clear explanation for what is driving the widening.
