A new semiconductor architecture integrates traditional electronics with photonic, or light, components could have application in advanced radar, satellites, wireless networks and 6G telecommunications. And it provides a pathway for a local semiconductor industry.

Researchers at the University of Sydney Nano Institute have invented a compact silicon semiconductor chip that integrates electronics with photonic, or light, components. The new technology significantly expands radio-frequency (RF) bandwidth and the ability to accurately control information flowing through the unit.

Expanded bandwidth means more information can flow through the chip and th...

The asteroid that causes the Geminid shooting star swarm has also puzzled researchers with its comet-like tail. The infrared spectrum of rare meteorites helped to determine the composition of the asteroid.

Asteroid Phaethon, which is five kilometers in diameter, has been puzzling researchers for a long time. A comet-like tail is visible for a few days when the asteroid passes closest to the Sun during its orbit.

However, the tails of comets are usually formed by vaporizing ice and carbon dioxide, which cannot explain ...

The gene, dubbed Iditarod, seems responsible for exercise’s ability to clean up damaged cells. As the days get shorter and chillier in the northern hemisphere, those who choose to work out in the mornings might find it harder to get up and running. A new study in PNAS identifies a protein that, when missing, makes exercising in the cold that much harder – that is, at least in fruit flies.

A team from University of Michigan Medical School and Wayne State University School of Medicine discovered the protein in flies, which they named Iditarod after the famous long distance dog sled across Alaska, while studying metabolism and the effect of stress on the body.

They were particularly interested in a physiological process called autophagy wherein damaged...

NASA’s James Webb Space Telescope obtained images of the Ring Nebula, one of the best-known examples of a pla...
