 Doomsday Clock stays unchanged at three minutes to midnight The Iran nuclear deal and movement on climate change prompted the scientists who maintain the Doomsday Clock, a symbolic countdown to global catastrophe, to keep it unchanged on Tuesday at three minutes to midnight. The Doomsday Clock, devised by the Chicago-based Bulletin of the Atomic Scientists, is widely recognized as an indicator of the world's vulnerability to catastrophe. The Doomsday Clock's hands "are the closest they've been to catastrophe since the early days of above-ground hydrogen bomb testing" in the 1950s.

Body mass index (BMI) is a common measure of body fat, but new research shows that having a BMI in the "normal weight" range is not always the healthiest for every person. In fact, for many people, having a BMI in the overweight range may be linked with the lowest risk of dying over a 13-year period, the research suggests. Usually, a BMI below 18.5 is considered underweight, from 18.5 to 24.9 is considered normal weight, from 25 to 29.9 is considered overweight, and 30 and over is considered obese.

"The risk of heat extremes has been multiplied due to human greenhouse-gas emissions, as our data analysis shows," study co-author Stefan Rahmstorf said in a statement. "The anomalous warmth has led to unprecedented local heat waves across the world, sadly resulting in loss of life and aggravating droughts and wildfires," said Rahmstorf, a professor at the Potsdam Institute for Climate Impact Research in Germany.
