Canadian researchers have built a gecko-like robot, which is able to stick to vertical surfaces by means of dry microscopic toe hair. European scientists say it could one day be deployed in space to help tend the hulls of spacecraft.
Two teams of scientists using NASA’s Hubble Space Telescope have discovered thick cloud layers in the atmospheres of two nearby exoplanets: a "warm Neptune" and a super-Earth. The study could help to identify potentially habitable Earth-like planets.
