Perseverance takes the first picture of a visible Martian aurora
A faint yet visible Martian aurora is the first instance of the phenomenon spotted from another planet's surface.
- Paleontology
This exquisite Archaeopteryx fossil reveals how flight took off in birds
Analyses unveiled never-before-seen feathers and bones from the first known bird, strengthening the case that Archaeopteryx could fly.

HHS says new vaccines should be tested against placebos. They already are
Placebo testing has been part of the process since the 1940s. It’s unclear what additional measures would achieve — but it may slow development.
- Animals
Wild chimpanzees give first aid to each other
A study in Uganda shows how often chimps use medicinal plants and other forms of health care — and what that says about the roots of human medicine.
- Plants
A leaf’s geometry determines whether it falls far from its tree
Shape and symmetry help determine where a leaf lands — and if the tree it came from can recoup the leaf’s carbon as it decomposes.

Humans have shockingly few ways to treat fungal infections
It's not quite as bad as The Last of Us. But progress has been achingly slow in developing new antifungal vaccines and drugs.

This tool-wielding assassin turns its prey’s defenses into a trap
This assassin bug's ability to use a tool — bees’ resin — could shed light on how the ability evolved in other animals.
- Chemistry
A chemical in plastics is tied to heart disease deaths
In 2018, over 350,000 excess heart disease deaths were linked to phthalates. More research is needed to fully understand the chemicals' effects.

Skyborne specks of life may influence rainfall patterns
A study of weather on a mountain in Greece reveal that bioparticles in the sky may drive fluctuations in rainfall patterns more broadly.

Neandertals may have hunted in horse-trapping teams 200,000 years ago
A revised age for a German site indicates that our evolutionary cousins organized horse ambushes around 200,000 years ago.

Chimp chatter is a lot more like human language than previously thought
Chimpanzees combine hoots, calls and grunts to convey far more concepts than with single sounds alone. It may be a first among nonhuman animals.

How to fight Lyme may lie in the biology of its disease-causing bacteria
The unusual molecular makeup of Borrelia burgdorferi, which causes Lyme disease, may hold clues for understanding and treating the tick-borne disease.
