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
NASA’s Curiosity rover has entered a Martian valley covered by an astonishing “sea” of tiny polygon-shaped fractures。 The honeycomb patterns, each only a few inches wide, stretch across the landscape and even wrap around a nearby 20-foot-tall butte
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
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
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
It marks a change of tone for his administration, which has taken a more hands-off approach to the technology
