Halting irreversible changes to Antarctica depends on choices made today
Antarctic Peninsula projections show accelerating ice loss, warming oceans and global sea level impacts tied to greenhouse gas emissions.
- Chemistry
Machine learning streamlines the complexities of making better proteins
The framework predicts how proteins will function with several interacting mutations and finds combinations that work well together.
- Climate
Snowball Earth might have had a dynamic climate and open seas
Sediments from Scotland hint that ocean-atmosphere interactions continued more than 600 million years ago despite widespread ice.
- Paleontology
A mouth built for efficiency may have helped the earliest bird fly
A flexible tongue, sensitive beak and teethlike cones in the mouth may have helped Archaeopteryx generate enough energy to fly.
- Animals
Some dog breeds carry a higher risk of breathing problems
Research reveals more short-snouted dogs besides pugs and bulldogs that struggle with breathing. Pekingese and Japanese Chins topped the study's list.
- Animals
Regeneration of fins and limbs relies on a shared cellular playbook
The findings strengthen the case that regeneration is an old trait, offering insights into how complex tissues rebuild themselves.
- Physics
Physicists dream up ‘spacetime quasicrystals’ that could underpin the universe
Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

Some snakes lack the ‘hunger hormone.’ Experts are hungry to know why
The complex biology of ghrelin, the hunger hormone, has researchers wondering how its absence helps snakes last a long time with no food, if at all.
- Artificial Intelligence
Real-world medical questions stump AI chatbots
Subtle shifts in how users described symptoms to AI chatbots led to dramatically different, sometimes dangerous medical advice.
- Oceans
Evolution didn’t wait long after the dinosaurs died
New plankton arrived just a few millennia — maybe even decades — after the Chicxulub asteroid, forcing a rethink of evolution's catastrophe response speed.
- Animals
A sea turtle boom may be hiding a population collapse
In Cape Verde, conservation has boosted the sea turtle population 100-fold — but the male-female balance is way off.
- Astronomy
This inside-out planetary system has astronomers scratching their heads
A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red dwarf’s four worlds.
