Mineral evolution posits that Earth’s near-surface mineral diversity gradually increased through an array of chemical and biological processes. A dozen different species in interstellar dust particles that formed the solar system have evolved to more t…

Scientists have vaporized the Earth — if only by simulation, that is mathematically and inside a computer. They weren’t just practicing their evil overlord skills. By baking model Earths, they are trying to figure out what astronomers should see when …

You can freeze it, thaw it, vacuum dry it and expose it to radiation, but still life survives. Research on the International Space Station is giving credibility to theories that life came from outer space — as well as helping to create better sunscreens.

Scientists have recreated the conditions at Earth’s core-mantle boundary 2,900 km beneath the surface. Using X-rays at the European Synchrotron Radiation Facility, they probed tiny rock samples at extreme temperature and pressure showing for the first …
