Startup Deep Fission has come up with a new way to deal with the economic and safety problems of nuclear power that is, to say the least, novel. The idea is to build a reactor that’s under 30 inches (76 cm) wide and stick it down a mile-deep (1.6-km) drill shaft.

With its promise of limitless energy by breaking down matter itself, nuclear power has long held a utopian promise for humanity. However, economic and safety considerations, along with political opposition, have hindered its development – especially in the very countries that developed the technology.

The safety and economic factors are related because the high cost of building nuclear power stations has very little to do with the nuclear technology itself. Nuclear fuel, even with all the processing costs included, only comes to about US$1,663 per kilogram (2.2 lb). Because nuclear fuel has such an incredible energy density, that’s about 0.46 ¢/kWh – and the fuel costs keep dropping as the technology becomes more efficient.

Researchers at Swansea University, in collaboration with Wuhan University of Technology, Shenzhen University, have developed a pioneering technique for producing large-scale graphene current collectors.

This breakthrough promises to significantly enhance the safety and performance of lithium-ion batteries (LIBs), addressing a critical challenge in energy storage technology.

Published in Nature Chemical Engineering, the study details the first successful protocol for fabricating defect-free graphene foils on a commercial scale. These foils offer extraordinary thermal conductivity—up to 1,400.8 W m^–1 K^–1 —nearly ten times higher than traditional copper and aluminum current collectors used in LIBs.

Nvidia may have a sizable lead, but money is an excellent motivator, and tech companies old and new are striving to end its dominance of the AI chip market — or at least secure themselves a sizable slice of it.

While some of these groups, including AMD, are following Nvidia’s lead and optimizing GPUs for generative AI, others are exploring alternative chip architectures.

These models are very, very wrong.

ICYMI: Elon Musk’s social media platform X was instructed by a Brazilian court to name a local representative, but failed to do so.

The justice said the platform will stay suspended until it complies with his orders, and also set a daily fine of 50,000 reais ($8,900) for people or companies using…

SAO PAULO — Brazil started blocking Elon Musk’s social media platform X early Saturday, making it largely inaccessible on both the web and through its mobile app after the company refused to comply with a judge’s order.

A new study from scientists has claimed SpaceX’s explosion of its Starship rocket last year blew a first-of-its-kind hole in Earth’s atmosphere.

As the last man standing, he was tasked with fixing-up all the AI-generated articles that once would’ve been composed by dozens of writers.

Three days ago, an old Falcon 9 booster crashed and exploded while landing on a drone ship during its 23rd landing.

The FAA has cleared SpaceX to launch the Falcon 9 while the investigation into Wednesday’s mishap wraps up.

The retina and optic nerve share most of the brain’s biochemical properties – this way, they provide a ‘window’ into the biochemistry of the brain.

To address this lack of technological means for the early detection of TBI, Pola Goldberg Oppenheimer, a Professor in Micro-Engineering and Bio-Nanotechnology at the University of Birmingham, UK, has developed a groundbreaking laser-based, eye-safe device (EyeD) technology. This technology can detect molecular changes that reflect brain damage by scanning the back of the eye with a handheld device.
