A promising light source for optoelectronic chips can be tuned to different frequencies
Chips that use light, rather than electricity, to move data would consume much less power—and energy efficiency is a growing concern as chips' transistor counts rise.
Interactive dark matter could explain Milky Way's missing satellite galaxies
Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.

Researchers find security flaws in backscatter X-ray scanners
A team of researchers from the University of California, San Diego, the University of Michigan, and Johns Hopkins University have discovered several security vulnerabilities in full-body backscatter X-ray ...
Molecular engineers record an electron's quantum behavior
A team of researchers led by the University of Chicago has developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique ...
Computer scientist reviews frontier technologies to determine fundamental limits of computer scaling
From their origins in the 1940s as sequestered, room-sized machines designed for military and scientific use, computers have made a rapid march into the mainstream, radically transforming industry, commerce, ...
Beyond six nines: Ultra-enriched silicon paves the road to quantum computing
(Phys.org) —Using a relatively straightforward technique, a team of NIST researchers has created what may be the most highly enriched silicon currently being produced. The material is more than 99.9999% ...
Planting imperfections at specific spots within diamond lattice could advance quantum computing
By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum computers and nanoscale ...
Algorithm recovers speech from vibrations of potato-chip bag filmed through soundproof glass
Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were ...
