The failure of an experimental drug that targets clumps of protein inside the brains of Alzheimer's patients called into question one of the leading theories about the cause of the dementia.

They will also change the way we die. As technology takes the wheel, road deaths due to driver error will begin to diminish.

Tiny electric airplanes could become mainstream sooner than you think. People have dreamed about flying cars for decades, but the technology has always seemed far out of reach. Airplanes have long been too big, expensive, dangerous, loud, and complex for personal aviation to be more than a hobby for rich people. But that might be about to change. “There’s a couple of technologies that are maturing and converging” to make small, affordable airplanes feasible, says Brian German, an aerospace researcher at Georgia Tech. German argues that lighter and more powerful electric motors, batteries that can store more energy…
Research on men's birthrates have so far been rather a blind spot. Max Planck researchers have now calculated the missing age data for men using statistical methods. Their figures show that men on average have less children than women and have them later in life. Differences are especially strong in eastern Germany, where men set a new world record for low fertility.
