ancient lava

MURDEROUS MAGMA  Gases coughed up by the Siberian Traps volcanic eruptions could have triggered the Permian extinction around 252 million years ago, new research demonstrates. Researchers measured the age of the eruptions by analyzing crystals embedded in ancient lavas (shown).

POWER SQUEEZE  With a squeeze, swing or jiggle, body motion can flex a triboelectric nanogenerator (left) to create voltage (right), which can charge implantable and wearable medical devices. Textured surfaces within the generator can boost the power output.

CSI: SCIENCE  From fingerprints to blood splatters to DNA, people leave all sorts of traces at the scene of a crime. To help identify suspects, scientists are beefing up classic forensic techniques, and coming up with new ones. One day, microbes and odors from a suspect’s body may give investigators additional pieces of evidence to examine.
