A newfound blood biomarker may one day predict longevity
Levels of six RNA molecules in the blood ID’d older adults likely to survive two more years. Whether it will work for other people is a big question.
- Climate
Why we fail to notice climate change
People quickly normalize extreme weather. Simple visuals highlighting abrupt change could help climate change break through our mental blind spots.
- Paleontology
A large fossil leg bone hints at T. rex’s origins, but scientists disagree
A new analysis of a large fossil shinbone suggests T. rex ancestors came from North America instead of Asia. Not everyone agrees.
- Genetics
Why African striped mice can be the best of dads — or the worst
Environmental cues can flip a molecular switch in the brain, turning males from caregivers to killers.

AI may be giving teens bad nutrition advice
AI-generated meal plans for fictional teens cut an entire meal’s worth of calories and carbs while overemphasizing protein and fats, a new study reports.
- Space
One possible recipe for life on Titan is a bust
An experiment mimicking conditions on the Saturn moon suggests that cell-like bubbles don’t form in methane lakes, puncturing hopes for alien life.

AI auto-complete may subtly shape views on social issues
People are increasingly using AI auto-complete features when writing. Unbeknownst to them, that feature may change how they think.

The Amazon molly — a sex-skipping fish — hacks evolution
The Amazon molly reproduces without sex. A genomic copy-and-paste trick called gene conversion may explain how it avoids evolutionary meltdown.
- Astronomy
A strange ‘chirp’ in a brilliant stellar blast points to a magnetar
Superluminous supernovas are the brightest stellar explosions in the universe. Astronomers may have found a mechanism that can trigger these events.
- Animals
Submerged bumblebee queens breathe underwater
Submerged bees breathe and use strategies that don’t require oxygen, lab tests show. In nature, that trick could help the bees survive floods.
