Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts. The finding may help reveal where the Milky Way's most energetic cosmic rays come from and how they influence the ...

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.

Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in supernova remnants, nearby explosions, and stars ...

Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with ...

Ant parenting may have evolved from the same brain systems that once controlled hunger. Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants .. ...

Scientists discovered unusually high water-vapor supersaturation inside deep tropical clouds, creating conditions in which tiny aerosol particles could intensify storm updrafts. The finding suggests earlier studies may have missed the effect because ...

Scientists studying magma from the 2021 Tajogaite eruption on La Palma have discovered that extreme heat can dramatically change how an eruption unfolds. When magma becomes superheated, it can dissolve the tiny crystal seeds that normally trigger ...

Modern humans carry DNA from two mysterious extinct lineages in addition to Neanderthals and Denisovans. Their hidden genetic legacy shows that our evolutionary past was shaped by repeated mixing among many different human groups.

A new chemical process can transform three of the most common plastics into high-purity hydrogen without sorting them first. The technique operates at much lower temperatures than traditional gasification and captures most of the plastic's carbon in ...

A gene involved in the brain's overnight cleaning system may change how strongly poor sleep affects Alzheimer's-related brain changes. The findings point toward more personalized prevention strategies based on both genetics and sleep habits.
