More left-handed men are born during the winter: Indirect evidence of a hormonal mechanism

Men born in November, December or January are more likely of being left-handed than during the rest of the year. While the genetic bases of handedness are still under debate, scientists at the Faculty of Psychology, University of Vienna, obtained indirect evidence of a hormonal mechanism promoting left-handedness among men.

Psychologist Ulrich Tran and his colleagues published their findings in the scientific journal Cortex.

Watching too much TV may increase risk of early death

Adults who watch TV for three hours or more each day may double their risk of premature death compared to those who watch less, according to new research published in the Journal of the American Heart Association.

"Television viewing is a major sedentary behavior and there is an increasing trend toward all types of sedentary behaviors," said Miguel Martinez-Gonzalez, M.D., Ph.D., M.P.H., the study's lead author and professor and chair of the Department of Public Health at the University of Navarra in Pamplona, Spain. "Our findings are consistent with a range of previous studies where time spent watching television was linked to mortality."

Washing chicken 'spreads infection'

Consumers are being warned to stop washing raw chicken as doing so increases the risk of food poisoning.

An online survey of 4,500 UK adults by the Food Standards Agency (FSA) found 44% washed chicken before cooking.

But it warns this spreads campylobacter bacteria onto hands, work surfaces, clothing and cooking equipment, through the splashing of water droplets.

Campylobacter affects about 280,000 people in the UK each year but only 28% in the FSA survey had heard of it.

 

However 90% had heard of salmonella and E. coli.

Google to test 200 self-driving cars

General Motors. Toyota. Google?

One of the world's largest technology companies is getting into the car business — and hoping to turn drivers into passengers. The tech giant announced on its blog Tuesday that it plans to test about 200 of its own two-seat self-driving cars.

"We've been working toward the goal of vehicles that can shoulder the entire burden of driving," the company wrote. "They will take you where you want to go at the push of a button. And that's an important step toward improving road safety and transforming mobility for millions of people."

Charging portable electronics in 10 minutes

Researchers at the University of California, Riverside Bourns College of Engineering have developed a three-dimensional, silicon-decorated, cone-shaped carbon-nanotube cluster architecture for lithium ion battery anodes that could enable charging of portable electronics in 10 minutes, instead of hours

Lithium ion batteries are the rechargeable battery of choice for portable electronic devices and electric vehicles. But, they present problems. Batteries in electric vehicles are responsible for a significant portion of the vehicle mass. And the size of batteries in portable electronics limits the trend of down-sizing.
