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
“It just seems like the temperature is rising on Silicon Valley
The disclosure followed OpenAI’s report last week that its own artificial intelligence had hacked into the network of an online library
A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials。 By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to more efficient manufacturing
Rogue AI agents from OpenAI and Anthropic have again been caught trying to disrupt servers and software—and leaving instructions for future bad behavior
The Trump administration has struggled with how to approach “open source” models, which are freely available to download and favored by Chinese companies
Scientists have identified a molecular switch that may help explain why aging makes the brain more vulnerable to diseases such as ALS and Huntington’s。 In worms, the protein EPS8 builds up with age and triggers signaling that encourages toxic proteins to clump together, damaging neurons and shortening lifespan。 Reducing EPS8 activity prevented thes
The UK's AI Safety Institute said recent behaviour from Anthropic and OpenAI models was malicious and unprecedented
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 Trump administration shared the details of its plan with OpenAI, Anthropic, and other AI labs on Tuesday。 For now, the public remains in the dark
Anthropic and OpenAI models’ unprompted actions forced halt to UK cyber tests
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
A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems。 Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the risk of six major cardiovascular diseases, including heart attack, stroke, heart failure, and atria
Open-weight AI models are having a moment in the wake of recent turmoil at US tech giants。 For French AI lab Mistral, that’s the the best thing that could have happened
Hi HN, this is Shailendra and Karan here。 We are building a fast and safe way for coding agents to debug issues live in production。When prod breaks, it lets Cursor, Claude, and others drop virtual breakpoints or probes safely in your running code, and extract the exact variable values that logs don’t have
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
