A simple colour change could indicate the presence of potentially hazardous hydrogen gas thanks to a new sensor developed by researchers in Germany. The micron-scale device, which uses so-called “supraparticles” that turn from purple to pink in the presence of hydrogen, could help prevent explosions by making it easier to detect and localize leaks at fuel stations, generators and pipelines.

Sending miniature robots deep inside the human skull to treat brain disorders has long been the stuff of science fiction—but it could soon become reality, according to a California start-up.

Bionaut Labs plans its first clinical trials on humans in just two years for its tiny injectable robots, which can be carefully guided through the brain using magnets.

“The idea of the micro robot came about way before I was born,” said co-founder and CEO Michael Shpigelmacher.

“GM and our suppliers are building an EV ecosystem that is focused on sourcing critical raw materials in a secure sustainable manner. Importantly, given the critical role of EVs in reducing the carbon footprint of the transportation sector, this agreement is aligned with our approach to responsible sourcing and supply chain management.”

GM and Glencore did not disclose the duration of the sourcing agreement or its value. Cobalt is a rare metal that makes up only 0.001% of the earth’s crust. Known for its heat-resistant properties, it is added to lithium-ion battery cathodes to improve energy density and battery longevity.

AMD is at it again. 😃

The launch of AMD’s Ryzen 7 5800X3D is imminent. Chips are out in the wild and early bird reviews and benchmarks are popping up on the web. Given that AMD has been touting the gaming prowess of the 5800X3D, we’ve been waiting to see if that claim holds up. And it appears that it does.

Peruvian hardware site Xanxo Gaming (via 3DCenter) managed to get hold of a retail Ryzen 7 5800X3D and put it through a comprehensive suite of benchmarks, comparing it to Intel’s Core i9 12900KF. As the site wasn’t sampled by AMD, it’s not subject to an embargo.
