Scientists Produce Rare Diamonds In Minutes At Room Temperature

Iwastheone writes: While traditional diamonds are formed over billions of years deep in the Earth where extreme pressures and temperatures provide just the right conditions to crystalize carbon, scientists are working on more expedient ways of forging the precious stones. An international team of researchers has succeeded in whittling this process down to mere minutes, demonstrating a new technique where they…

Hubble telescope reveals asteroid Psyche’s rusty surface

Scientists already had Psyche classified as a metallic asteroid, but new observations with the Hubble telescope reveal its rusty surface and provide scientists with a unique view into what Earth-like planets are like during their formation.

Shedding light on moiré excitons: A first-principles perspective

Moiré superlattices that are located within van der Waals (vdW) heterostructures can trap long-lived interlayer excitons to form ordered quantum dot arrays, paving the way for unprecedented optoelectronic and quantum information applications. Excitons are an electrically neutral quasiparticle that can transport energy without transporting net electric charge. They form when a material absorbs a photon of higher energy than its bandgap…

New York’s New Digital Subway Map

An anonymous reader shares a report: The date was April 20, 1978; the scene, the Great Hall of the Cooper Union for the Advancement of Science and Art on Astor Place. On the stage where Abraham Lincoln once spoke sat two men, the Italian modernist Massimo Vignelli and the cartographer John Tauranac, constituting two sides of the Great Subway Map Debate….

The strange storms on Jupiter

At the south pole of Jupiter lurks a striking sight—even for a gas giant planet covered in colorful bands that sports a red spot larger than the earth. Down near the south pole of the planet, mostly hidden from the prying eyes of humans, is a collection of swirling storms arranged in an unusually geometric pattern.

Apple Researching Apple Watch Bands That Can Provide Information In Braille

According to Apple Insider, Apple is researching an Apple Watch band that could contain controllable protrusions to present tactile information on the surface. From the report: Apple has famously always researched providing accessibility features in its devices, whether or not it’s profitable. However, so far there has been a limit to what the Apple Watch can do — and its bands…

What are brown dwarfs?

A brown dwarf is more massive than a planet, but less massive than a star. Exactly how much more and less? Source: https://earthsky.org/space/definition-what-are-brown-dwarfs…
