In the biological sciences, a team of neuroscientists showed how the brain works during meditation, and it apparently does so in different ways depending on which type of meditation you’re doing. Another team has found the brain’s response to sexual images is linked to the number of sexual partners. It seems the more real-world sexual encounters with different people a person has, the more strongly they react to sexual imagery—a find that just might cause advertisers to react.It’s also been a good week for technology as researchers developed an ultra-fast bionic arm that can catch objects on the fly. It sits there waiting, then reacts in less than a second, manipulating its parts to allow it to catch all manner of objects, from tennis rackets to soda bottles. Very impressive. Also, Power Japan Plus announced a dual carbon battery that charges 20 times faster than current lithium ion batteries—it’s made mostly of carbon grown from cotton fibers and doesn’t overheat. Maybe electric cars will be the wave of the future after all. And speaking of the future, operation of the longest superconducting cable worldwide started—engineers in Essen, Germany are laying down the cable between two power transformers in the city, it transports five times more power than conventional lines and is far more efficient.And finally, sadly, it appears that drinking wine and eating chocolate won’t keep you alive longer as diets rich in antioxidant resveratrol fail to reduce deaths, heart disease or cancer—the study by a team at John’s Hopkins University found that anecdotal evidence of health benefits from the chemical were completely misguided. Sad, very sad indeed.
