Scientists capture a magnetic flip in 140 trillionths of a second

Scientists at the University of Tokyo have captured something never seen before: a frame-by-frame view of how electron spins flip inside an antiferromagnet, a material once thought to be magnetically “invisible.” By firing ultrafast electrical pulses into a thin layer of manganese–tin and tracking the response with precisely timed flashes of light, the team uncovered […]

World’s smallest OLED pixel could transform smart glasses

Researchers have built the smallest OLED pixel ever made—just 300 nanometers across—without sacrificing brightness. By redesigning the pixel with a nano-sized optical antenna and a protective insulation layer, they prevented the short circuits that normally plague devices at this scale. The result is a stable, ultra-tiny light source that could allow full HD displays to

The hidden technology that could unlock commercial fusion power

Fusion energy may be one of the most promising clean power sources of the future—but only if scientists can precisely measure the extreme, fast-moving plasmas that make it possible. A new U.S. Department of Energy–sponsored report urges major investment in advanced diagnostic tools—the high-tech “sensors” that track plasma temperature, density, and behavior inside fusion systems.

A lost moon may have created Titan and Saturn’s rings

Saturn’s largest moon, Titan, may have been born in a colossal cosmic crash. New research suggests Titan formed when two older moons slammed together hundreds of millions of years ago—an event so violent it reshaped Saturn’s entire moon system and may have indirectly sparked the formation of its iconic rings. Clues come from Titan’s unusual

ChatGPT as a therapist? New study reveals serious ethical risks

As millions turn to ChatGPT and other AI chatbots for therapy-style advice, new research from Brown University raises a serious red flag: even when instructed to act like trained therapists, these systems routinely break core ethical standards of mental health care. In side-by-side evaluations with peer counselors and licensed psychologists, researchers uncovered 15 distinct ethical
