Ancient humans may have had apelike brains even after leaving Africa
Modern humanlike brains may have evolved surprisingly late, about 1.7 million years ago, a new study suggests.

How matter’s hidden complexity unleashed the power of nuclear physics
In the last century, physicists learned to split atomic nuclei and revealed a complex world of fundamental particles.

AstraZeneca’s COVID-19 vaccine is tied to uncommon blood clots in rare cases
Blood clots should be listed as a possible side effect of AstraZeneca’s vaccine, but its benefits still outweigh the risks, experts say.

People add by default even when subtraction makes more sense
People default to addition when solving puzzles and problems, even when subtraction works better. That could underlie some modern-day excesses.

Muon magnetism could hint at a breakdown of physics’ standard model
After two decades, a new measurement of the muon magnetic anomaly reinforces earlier hints that its value disagrees with standard physics.

Europe’s oldest known humans mated with Neandertals surprisingly often
DNA from ancient fossils suggests interbreeding regularly occurred between the two species by about 45,000 years ago, two studies find.

Tiny crystals give a plain fish twinkling, colorful dots under light
Fishes’ flashing photonic crystals may provide inspiration for ultra-miniaturized sensors that work in a living body.

Yawning helps lions synchronize their groups’ movements
A lion yawn is contagious, and when lions start yawning together, they start moving together. Synchronization may be key for group hunters like lions.

‘Pipe Dreams’ flushes out hope in an unexpected place: the toilet
A new book shows how reimagined toilets will allow humans to use pee and poop as natural resources.

A spike in Arctic lightning strikes may be linked to climate change
Global warming may be revving up summer thunderstorms in the Arctic, leading to skyrocketing numbers of lightning strikes.

New depictions of ancient hominids aim to overcome artistic biases
Artists’ intuition instead of science drive most facial reconstructions of extinct species. Some researchers hope to change that.

Newly made laser-cooled antimatter could test foundations of modern physics
Physicists have finally used laser cooling to tame unruly antimatter atoms. That could allow new tests of symmetry and Einstein’s theory of gravity.
