- Tech
A man silenced by paralysis got his ‘voice’ back, thanks to AI
New computer-linked brain implants offer hope to those who have lost the ability to speak or move.
- Animals
Let’s learn about octopuses
These clever, color-changing cephalopods live all over the world.
- Brain
Scientists Say: Dopamine
This brain chemical helps focus our attention and plan our path toward success.
- Physics
Shark intestines inspire pipes with a strictly one-way flow
The pipes contain a twisty coil that lets liquids flow in one direction but not the other.
- Math
Two teens have proved an ancient math rule — again
Ne’Kiya Jackson and Calcea Johnson proved math's Pythagorean theorem — in a way thought impossible for 2,000 years — and they did it 10 different ways.
- Computing
A new frontier awaits — computing with light
Today’s computers process using electrical signals. But light shows promise as a new means of computing, especially for AI.
- Animals
Wayward baby puffins get help from a community-led Puffling Patrol
Fitted with ID tags or tracking devices, birds from one Iceland colony give scientists an eye into puffins’ largely unknown lives at sea.
- Artificial Intelligence
Google now adds watermarks to all its AI-generated content
Google’s AI-created content now hosts an invisible “signature.” A mathematical key can reveal the presence of this digital watermark, called SynthID.
- Animals
Putting vampire bats on treadmills revealed an energy-burning quirk
A mini gym for bats shows that vampire bats burn amino acids, rather than the carbs or fats other mammals rely on during exercise.
- Materials Science
Experiment: The surprising strength of eggshells
Architecture is full of arched doors, windows and other structures. But how strong is the natural arch of eggshells?
- Climate
Trees may be even bigger climate heroes than we thought
These plants absorb methane, a potent greenhouse gas, in addition to carbon dioxide. Methane’s uptake is likely thanks to microbes living in tree bark.
- Life
Scientists Say: Organoid
Lab-grown organ models mimic the functions of real organs and may open doors to a future of personalized medical care.
