Gravity may seem constant, but it actually varies across the planet--and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this "gravity hole" to slow, deep movements of rock inside ...

A team of physicists has experimentally confirmed a long-predicted sequence of exotic magnetic phases in an atomically thin material. When cooled, the material forms tiny magnetic vortices before transitioning into a second ordered magnetic state- .. ...

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a gigantic, flat sheet of matter surrounded by huge empty ...

Electrons in solar materials can be launched across molecules almost as fast as nature allows, thanks to tiny atomic vibrations acting like a "molecular catapult." In experiments lasting just 18 femtoseconds, researchers at the University of ...

Researchers at Cornell University have developed a powerful imaging technique that reveals atomic scale defects inside computer chips for the first time. Using an advanced electron microscopy method, the team mapped the exact positions of atoms ...

A sweeping new ALMA image has peeled back the veil on the Milky Way's core, exposing a dense network of cold gas filaments near the central black hole. Stretching across 650 light-years, the survey maps the hidden fuel for star formation in ...

A new ultrathin photodetector from Duke University can sense light across the entire electromagnetic spectrum and generate a signal in just 125 picoseconds, making it the fastest pyroelectric detector ever built. The breakthrough could power next ...

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 ...

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 ...

Researchers at Kobe University have developed an AI system that can detect acromegaly, a rare hormone disorder, by analyzing photos of the back of the hand and a clenched fist. The disease often develops slowly and can take years to diagnose, even .. ...
