Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds。 The breakthrough could open the door to ultrafast computing, smarter communication systems, advanced imaging, and a new generation of highly tunable lasers
As Silicon Valley debates how artificial intelligence software should be created, “open weights” have been a major part of the discussions。 Here’s what to know
It marks a change of tone for his administration, which has taken a more hands-off approach to the technology
I've been working on Bor, an open-source system for centralized Linux desktop management。Bor consists of a lightweight Go agent and a central server。 Policies are streamed to clients over mTLS/gRPC in real time—no polling—and currently support Firefox, Chrome, KDE, dconf, polkit and package management, with more coming
SJY’s Zeph are brilliant wired headphones, using flippable earcups for two different takes on your favorite music
In an interview with The Times, Meta’s chief executive took aim at Anthropic and OpenAI, which have pushed to tightly control A。 development, and said he supported “more openness
Ultrafast X-rays revealed how a molecule converts absorbed light into motion in just trillionths of a second。 Individual atoms recorded different stages of the process, opening a powerful new window into light-driven chemistry
The first U。 attempt at reopening a shuttered reactor has been held back by run-down equipment and a lack of planning
A surprisingly simple change could make sodium-ion batteries far more powerful while opening the door to turning seawater into drinking water。 Researchers at the University of Surrey found that sodium vanadium oxide performs much better when its naturally occurring water is left inside instead of being removed during manufacturing
Scientists say new technologies have reopened the debate over whether Mars could someday be terraformed, turning a once impossible idea into a serious research topic。 Before anyone tries to reshape the Red Planet, though, researchers say we must understand the risks, including what might be lost if Mars already harbors its own forms of life
Newer oral drugs related to semaglutide medications such as Ozempic reduced pleasure-driven eating in mice by quieting a deep brain reward circuit。 The finding could open new avenues for understanding food cravings and potentially treating substance use disorder
