The steamiest summer day would be no sweat for this potential superconductor. Scientists have calculated that a hydrogen-rich compound could conduct electricity without resistance at temperatures up to about 200° Celsius — well above the 100° C boiling point of water. If that prediction is confirmed experimentally, the material would stand in stark contrast to […] More
“Silicon Valley” may soon be a misnomer. Inside a new microprocessor, the transistors — tiny electronic switches that collectively perform computations — are made with carbon nanotubes, rather than silicon. By devising techniques to overcome the nanoscale defects that often undermine individual nanotube transistors (SN: 7/19/17), researchers have created the first computer chip that uses […] More
Flame retardants are going green. Using compounds from plants, researchers are concocting a new generation of flame retardants, which one day could replace the fire-quenching chemicals added by manufacturers to furniture, electronics and other consumer products. Many traditional synthetic flame retardants have come under fire for being linked to health problems like thyroid disruption and […] More
Regular old quantum teleportation wasn’t enough for scientists. So they’ve kicked it up a notch. Previously, physicists had teleported qubits, or quantum bits of information. Just as a standard bit in a desktop computer has two possible values, 0 or 1, a qubit has two possible states. Now scientists have moved on, reporting in the […] More
It’s a moonless night. The wind howls outside. A door opens slowly, as if pushed by an invisible hand. “Cre-e-e-a-k.” That sound — a horror movie cliché — is the result of friction. 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
