Phys.org / One of the most distant 'leaky' galaxies ever found may reveal how the universe reionized

Astronomers have identified one of the most distant candidate galaxies known to leak ionizing radiation—the same kind of radiation thought to have transformed the early universe during the epoch of reionization.

Phys.org / Mice actively seek better views to make visual decisions, virtual reality experiments show

Animals don't experience the world passively. A hawk tilts its head to track prey. A person leans forward to read a sign. Scientists call this "active sensing": moving the body to gather better information. A specific version ...

Phys.org / Why some wolves react more strongly to trespassers: Breeders may hold key to scent-based barriers

Wolves use their urine to communicate with each other. A recent study looked at the reactions of a pack to the marking of an intruder. This is a first step toward understanding what attracts or repels canids.

Phys.org / A cataclysmic collision in space provides new clues on astronomy's biggest stalemate

Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time that we can detect on Earth.

Phys.org / Industrial-era pollution and warming reshape Tibetan lake after 1,000 years of climate swings

The Tibetan Plateau, together with the Hindu Kush–Karakorum–Himalaya region, has more snow and ice than any other region on Earth apart from the polar regions. As a result, this high-altitude region is particularly sensitive ...
