The disclosure followed OpenAI’s report last week that its own artificial intelligence had hacked into the network of an online library
Plus: The FBI eyes AI-powered tech to detect future crimes, Russia charges Telegram’s founder, xAI sues to stop a state’s “nudification” ban, and the Democrats learn a lesson about getting scammed
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
Try DGX Spark playbooks using Nix on DGX OS, or install NixOS on your DGX Spark for the full Nix experience。 The repository provides USB images and a NixOS module with settings for DGX Spark systems。This works on the NVIDIA DGX Spark itself and also on the Asus Ascent GX10
More than 150 years after Darwin’s finches helped reshape biology, Galápagos plants are exposing another evolutionary surprise。 Giant daisies repeatedly developed similar heat-tolerant leaf shapes, but each lineage used a different combination of genes。 Researchers also found major genetic differences among isolated populations, suggesting new spec
Wavelength and intensity in the infrared are translated into colors in the visible
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
Cancer cells rely on powerful genetic switches to keep growth genes running at full speed, but that intense activity can damage their own DNA。 The resulting breaks are repeatedly repaired, sometimes with small mistakes that allow new mutations to accumulate。 Researchers believe this self-inflicted damage may help tumors evolve while also creating a
New research challenges the decades-old idea that children experience an “adiposity rebound” when their BMI begins rising around age 6。 Although BMI returns to earlier levels, a more reliable measure showed that body fat does not rebound at all。 The increase appears to come from growing muscle and lean tissue as children prepare for later growth
It marks a change of tone for his administration, which has taken a more hands-off approach to the technology
Mathematicians have shown that no electoral system can perfectly balance local representation, proportional national results, and a fixed-size parliament once enough parties compete。 A newly proposed voting method could soften these unavoidable trade-offs and produce outcomes that are much closer to fair
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
