Ancient DNA unveils disparate fates of Ice Age hunter-gatherers in Europe
Ancient DNA unveils two regional populations that lived in what is now Europe and made similar tools but met different fates.

Here’s how lemon juice may fend off kidney stones
Lemon nanoparticles slowed formation of kidney stones in rats. If the sacs work the same way in people, they could help prevent the painful crystals.

Medicated eye drops may delay nearsightedness in children
Myopia, or nearsightedness, is a growing global health threat. But a Hong Kong study found that medicated eye drops may delay its onset in children.

Trauma distorts our sense of time and self. A new therapy might help
The therapy has helped veterans struggling with mental illness imagine their future selves.
- Humans
A new biomaterial heals heart attack damage in animals. Humans could be next
If used right after a heart attack, this intravenously delivered biomaterial can preserve cardiac function. It could also treat traumatic brain injury.

A gel cocktail uses the body’s sugars to ‘grow’ electrodes in living fish
A chemical reaction with the body’s own sugars turned a gel cocktail into a conducting material inside zebrafish brains, hearts and tail fins.
- Archaeology
Homo sapiens may have brought archery to Europe about 54,000 years ago
Small stone points found in a French rock-shelter could have felled prey only as tips of arrows shot from bows, scientists say.
- Science & Society
Lots of people feel burned out. But what is burnout exactly?
Researchers disagree on how to define burnout, or if the phenomenon is really another name for depression. Helping people cope at work still matters.

Fungi don’t turn humans into zombies. But The Last of Us gets some science right
Fungi like those in the post-apocalyptic TV show are real. But humans’ body temperature and brain chemistry may protect us from zombifying fungi.
- Health & Medicine
A new treatment could restore some mobility in people paralyzed by strokes
Electrodes placed along the spine helped two stroke patients in a small pilot study regain control of their hands and arms almost immediately.

Psychedelics may improve mental health by getting inside nerve cells
Psychedelics can get inside neurons, causing them to grow. This might underlie the drugs’ potential in combatting mental health disorders.
