A group of scientists at UC-Berkeley devised a flexible mesh using nanowires to create a substance that reacts to pressure, and, as their paper in Nature Materials said, “effectively functions as an artificial electronic skin.” In the same issue, a team from Stanford University announced it had devised a kind of skin so sensitive, it can detect the weight of a bluebottle fly.

One 19-year-old had a resting heart rate of 82 beats a minute. Half an hour later, after consuming an energy drink, it hit 106.A Queensland Health spokeswoman said the effects of two energy drinks on a child weighing less than 30kg could be dangerous.“Current evidence suggests that 75mg of caffeine per day from all food and drink sources is the limit for a 30kg …
