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 distinct periodic light going on and off like a candle from its host star eac...

Journalist Edward Zitron wrote that Altman was “a false prophet – a seedy grifter that uses his remarkable ability to impress and manipulate Silicon Valley’s elite”. Ellen Huet of Bloomberg News, on the podcast Foundering, reached the conclusion that “when [Altman] says something, you ...
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...
Who would have guessed 10 years ago that AWS was going to dominate public infrastructure computing and be worth several hundred billion dollars or multiples of Amazon market cap at the time? Not even Bezos. Even without AWS, an investment in Amazon shares would have yielded a fantastic 10-year...
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 Hunt...
Our photovoltaic layer production process hinges on the discovery that PEDOTPSS layers function effectively on heavily doped silicon substrates, thereby significantly lessening the demands placed upon electrode placement. The proposed approach to solar cell fabrication may lead to a low-cost, high-...
Discovered by Robert Dyer in the late 1670s (1), they experienced several periods of mining from the 17th through 19th century. The first phase was from discovery until the American Revolution, which halted operations. I have heard though I cannot confirm that lead from Loudville was used in...
A recent awareness regarding the origins of chert & flint: If early Earth didn’t possess diatom-radiolarians or sponges (both of which build their skeletons from silicon) the deposition of silicon on the sea floor would not have allowed for the generation of those glass-like minerals, without...
“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...
