Underground Detector Pushes Neutrino Science Forward

Deep beneath the mountains of Guangdong Province, China, the Jiangmen Underground Neutrino Observatory (JUNO) has begun delivering on its scientific promise. After collecting just 59 days of data, the massive underground detector has produced some of the most precise measurements yet of how neutrinos transform as they travel—bringing physicists

Cold Atom Experiment Suggests Time May Emerge from Quantum Interactions

A team of physicists has created an experimental model using ultracold atoms that suggests time may not be a fundamental aspect of the universe, but rather something that arises from quantum interactions. The experiment, described as a "toy universe," uses atoms cooled to near absolute zero to simulate

First Nuclear Clock Demonstrated, Promising Greater Precision

A New Kind of Clock Scientists have achieved a long-anticipated milestone by creating the world's first nuclear clock. Unlike traditional atomic clocks, which rely on electrons orbiting an atom's nucleus, nuclear clocks use the nucleus itself as their timekeeping element. This approach, first proposed decades ago,

Battery-Free Solar Fuel System Could Simplify Clean Energy Production

Scientists have developed an artificial photosynthesis system that essentially regulates itself, removing the need for batteries used in many current solar fuel designs. The key innovation is an electrolyzer that automatically adapts to changing sunlight by altering its electrical properties as it heats up. This self-regulating behavior keeps solar fuel

James Webb Space Telescope Reveals Stark Twilight Differences on Exoplanet WASP-121 b

The James Webb Space Telescope (JWST) has provided unprecedented insights into the atmospheric dynamics of WASP-121 b, a scorching exoplanet located in a close orbit around its host star. The observations reveal striking contrasts between the planet's dawn and dusk regions that challenge existing atmospheric models. Asymmetric Atmospheric

Small Tropical Nuclear War Could Devastate Ozone Layer, New Models Show

Climate models are revealing a troubling outcome of nuclear conflict in the tropics: even a relatively small-scale nuclear war between India and Pakistan could destroy significant portions of Earth's ozone layer. The research suggests that a conflict involving roughly 250 Hiroshima-sized nuclear weapons—a fraction of the global

James Webb Space Telescope Finds Strongest Evidence Yet for 'Black Hole Stars'

NASA's James Webb Space Telescope has produced its strongest evidence yet for the existence of 'black hole stars'—hypothetical objects that could help explain a puzzling astronomical phenomenon first observed in 2022. The discovery centers on the so-called "little red dots," compact celestial objects
