What is under the microscope: Nettle or Velcro?

The leaves and stalk of the nettle are full of hairs that look like deadly spines up close. The hairs are tubes of pebble, a form of glass that breaks off even at the slightest touch and leaves a sharp fracture surface, such as when you hit the neck of a bottle.

Do you get a beer belly from too much beer?

In a large German study, scientists followed 20,000 men and women for eight years, until 2009, and compared their beer consumption with their weight and waist. The conclusion was that men with a big belly took more calories than they consumed, whether those calories came from beer or not. In men, the excess kilos on genetic grounds are mainly in the belly fat, and in women the sex hormones ensure that the majority of the fat ends up on hips, buttocks and thighs.

Astronomers search for life on strange moons

A dip in the light, followed by an even smaller dip - three times in a row. That makes the astronomers happy, because those light dips can be the first indications of a moon in a strange solar system: an exomaniac. That potential exoman, Kepler-1625b I, popped up in the mountains of data that the Kepler, NASA's space telescope, collected from 2009 to 2013.
