After Nearly 80 Years of Doubt, Scientists Say a Spear Lodged Between Elephant Ribs Offers Evidence That Neanderthals Hunted Big Game

In 1948, amateur archaeologists unearthed the remains, which should have shifted researchers’ views of Neanderthals. But poor documentation sowed skepticism in the scientific community

The researchers primarily studied California two-spot octopuses.

New Fossils Discovered in China Hint That Complex Life Evolved Millions of Years Earlier Than Scientists Thought

The assemblage suggests that the ancestors of some of today’s animal groups may have arisen before the famed Cambrian explosion

Becoming an expert birder might support brain health, according to a new study.

Becoming an Expert Birder Can Reshape Your Brain and Might Help Protect It From Aging, New Research Suggests

Compared with novices, seasoned birders had denser, more structurally complex brain regions involved with tasks like object identification, visual processing, attention and working memory

The last documented thylacine died at a zoo in Hobart in 1936, but people have reported hundreds of sightings of the extinct creature since then.

New Research

How Do Snakes ‘Stand’ Upright Nearly Stick-Straight? New Research Points to How They Pull Off the Gravity-Defying Feat

These clever creatures seem to concentrate their muscle activity near their bases, which helps them cross gaps between tree branches in the wild

Male reproductive cells, sperm, might struggle to reach and fertilize female reproductive cells, eggs, in microgravity, according to a new study.

Humans Might Struggle to Make Babies in Space. Sperm Gets Disoriented in Microgravity, a New Study Suggests

Simulated near-weightless conditions reduced human sperm’s navigational abilities

A new study is the first to “pinpoint which fragrances were actually burned in Pompeian domestic cult practices,” archaeologist Johannes Eber says.
