The presence of an animal can significantly increase positive social behaviors in children with autism spectrum disorders (ASD), according to a new paper.

Obesity rates across Canada are at alarming levels and continuing to climb, according to a new paper in the Canadian Journal of Public Health, which provides the first comprehensive look at adult obesity rates across Canada since 1998 - complete with "obesity maps."

If you liked FoxTrax, that glowing hockey puck shooting around the ice during NHL games, you will love what engineers from Carnegie Mellon University and the University of Electro-Communications (UEC) in Tokyo have done: they put a camera inside a football.

The camera is embedded in the side of a rubber-sheathed plastic foam football can record video while the ball is in flight. Want a ball's-eye view of the playing field? Now you have it. But because a football can spin at 600 rpm, the raw video is an unwatchable blur so the researchers also developed a computer algorithm that converts the raw video into a stable, wide-angle view.

Scientists say they have done laboratory resurrections of several 2 to 3 billion-year-old proteins, ancient ancestors of the enzymes that enable today's antibiotic-resistant bacteria to shrug off huge doses of penicillins, cephalosporins and other modern drugs.

Antibiotic resistance existed long before Alexander Fleming discovered the first antibiotic in 1928. Genes that contain instructions for making the proteins responsible for antibiotic resistance have been found in 30,000-year-old permafrost sediment and other ancient sites. The new study research focused on beta-lactamases, enzymes responsible for resistance to the family of antibiotics that includes penicillin, which scientists believe originated billions of years ago.

Older people who don't expect a satisfying future may be more likely to live longer, healthier lives than those who see brighter days ahead, according to a paper in
Psychology and Aging

Scholars examined data collected from 1993 to 2003 for the national German Socio-Economic Panel, an annual survey of private households consisting of approximately 40,000 people 18 to 96 years old. The researchers divided the data according to age groups: 18 to 39 years old, 40 to 64 years old and 65 years old and above.

Through mostly in-person interviews, respondents were asked to rate how satisfied they were with their lives and how satisfied they thought they would be in five years.

Trust fools you into remembering that your partner was more considerate and less hurtful than they actually were, say psychologists who examined the role of trust in biasing memories of transgressions in romantic partnerships. 

People who are highly trusting tended to remember transgressions in a way that benefits the relationship, remembering partner transgressions as less severe than they originally reported them to be. People low on trust demonstrated the opposite pattern, remembering partner transgressions as being more severe than how they originally reported them to be, they concluded.
