Researchers measure near-perfect performance in low-cost semiconductors

A leading artist rendering of light-emitting quantum dots that they absorbed. Credit: Ella Marushchenko Small, easy-to-produce particles called quantum dots could soon take the place of more expensive single-crystal semiconductors in advanced electronic devices in solar panels, camera sensors and medical imaging tools. Although quantum dots have begun to penetrate the consumer market, in the form of quantum dot TVs, …

This Star has been Kicked Out of the Milky Way. It Knows What It Did.

Every so often, the Milky Way expels a star. The ejected star is typically expelled from the chaotic area at the center of the galaxy, where our Super Massive Black Hole (SMBH) lives. But at least one of them has been expelled from the relatively calm galactic disk, a discovery that has rethought astronomers the whole phenomenon of expulsion of …

A Ferocious Shrimp Inspires a Robot Claw That Shoots Plasma

The shrimp pistol, aka shrimp, is a peculiar contradiction. A few centimeters long, he wields a claw of proportionate size and another massive one that snaps with such force that the resulting shock wave makes the cold prey fall. When the two bits of the claw come together, the bubbles form and then quickly collapse, firing a plasma projectile which …

Indian Scientists Measure 1.3-Billion-Volt Thunderstorm, the Strongest on Record

Lightning (not the one measured in this study) seen from the International Space Station beyond the Senegal-Mali border. Photo: NASA / ISS 16 (Wikimedia Commons) Scientists in India observed the highest-temporal tension ever documented with the help of a subatomic particle of which we don't hear much: the muon . Researchers manage the GRAPES-3 telescope, which measures muons, particles that …
