NASA’s James Webb Space Telescope has discovered a planet where it rains sand, in ground-breaking observation. The planet, WASP-107b, lying 200 light years away, was discovered in 2017 after astronomers spotted

A hidden quantum wave may keep particles moving, even when everything else freezes. Researchers discovered that phasons, a type of low-temperature quasiparticle found in crystal lattices, allow interlayer excitons to move, even at temperatures where motion is expected to stop. This finding advances ...
Over time, the company’s earning power will become increasingly evident to the market – this is a long-term thesis that requires time to play out after all (if the stock was obviously undervalued to the casual market observer, I would be less confident that it was wildly mis-priced). T...
In a relatively short time, Product Hunt has become a kind of early-warning system for apps that are about to break out. TapTalk,a fast-growing picture messaging app, got a seed investment from the venture capital firm SV Angel after a partner discovered it there. Traffic to Product ...
This is the appeal-to-authority fallacy – namely, framing an expert opinion as evidence rather than what it is – an opinion. Greenpeace does this throughout the piece, where almost every opinion they agree with becomes a “finding” or a “revelation” discovered through an “investigati...
These materials include silicon, silicon germanium, gallium arsenide, gallium nitride, halfnium and indium phosphide. These nano production processes are typical of semiconductor production processes. However, there are notable differences between the two....
The sodium, silicon monoxide, and silicon dioxide on K2-141b evaporate into mineral vapor, which is carried to the dark side of the planet by supersonic winds that rage over 3,100 miles per hour. From there, rocks "rain" back down into the 60-mile-deep magma ocean, which flows...
Used with conventional measuring machines, it was discovered that when workpieces made of light metal were being inspected, some of the metal adhered to the tip of the probe, so erroneous results were obtd. The invention avoids such problems.SCHUSTER,ERICH...
“These are places that are still being discovered,” says Arlt, who will publish a book on the next wave of China’s outbound tourism later this month. “Paris isn’t impressive anymore. If you tell your friends you’ve been to Albania, they will think you’re very special. That you...
