A stealthier entrance calls for oiling the door’s hinges. Friction is everywhere — from a violinist bowing a string to children skidding down […] More
Lab experiments characterize a phenomenon predicted by cosmologist Stephen Hawking NOT BLACK Stephen Hawking first proposed that black holes (illustrated) aren’t fully black, but emit a faint haze of particles that came to be known as Hawking radiation. Now scientists have measured the radiation’s temperature in a lab analog of a black hole. NASA’s Goddard […] More
LHC data suggests the subatomic particle’s constituent quarks and gluons share weird links TIED UP Protons contain smaller particles called quarks and gluons (illustrated). Experimental data suggest that quantum entanglement links those particles with one another. scify/Shutterstock Share this: This article is only available to Science News subscribers.

A variation of the classic double-slit experiment is applied to a positron for the first time MAKING WAVES The famous double-slit experiment (illustrated) has revealed that particles of matter, like electrons, are also waves. Now, researchers have performed a similar experiment to demonstrate antimatter’s wavelike behavior. RUSSELL KIGHTLEY/Science Source Share this: This article is only […] More
