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
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
Both major AI labs’ models broke containment, escaped onto the internet, and hacked other companies。 If a human had done that, the law would likely be against them
The out-of-control AI found four logins which allowed it to access multiple unnamed online services
“It just seems like the temperature is rising on Silicon Valley
It marks a change of tone for his administration, which has taken a more hands-off approach to the technology

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
The disclosure followed OpenAI’s report last week that its own artificial intelligence had hacked into the network of an online library
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
Lake fly larvae plunge more than 200 meters into Lake Malawi each day to hide from predators, using tiny air sacs to control their depth。 A rubber-like material called resilin lets them expand or shrink the sacs by changing their pH。 Their toughness challenges a popular explanation for why insects are absent from the open ocean
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
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
Hi HN, we’re Bence and Ryan, founders of Hoplite (https://hoplite。 Hoplite lets you deploy coding agents in the cloud, with a suite of tools that makes it incredibly easy to QA features。 During onboarding, we port over your local setup - sessions, memories, MCP servers, and get your projects ready to run in the cloud
A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware。 Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing some calculations to run on a laptop。 Their results matched both theoretical predictions and simula
