A swinging tube in the sea could offer a simpler way to harvest ocean...
Ocean currents carry vast amounts of energy, but turning that motion into electricity has always been a technical challenge.
Most existing designs rely on underwater...
AI can predict fall risk in older people in belly scans
A new study from Mayo Clinic shows that artificial intelligence (AI) can help spot people who may be more likely to fall—even as early...
AI system can detect early signs of cognitive decline
A research team from Mass General Brigham has built one of the first fully independent artificial intelligence (AI) systems that can detect signs of...
A lost ice age giant speaks again—from inside a wolf’s stomach
Scientists have recovered the complete genome of a woolly rhinoceros that lived more than 14,000 years ago—and they did it using tissue preserved inside...
Whale hunting in south America began 5,000 years ago—far earlier than we thought
The history of whale hunting is much older—and more global—than researchers once believed.
A new study shows that Indigenous communities living along the southern coast...
This gel-like material could boost battery life and prevent fires
Scientists at the Oak Ridge National Laboratory have developed a new kind of energy storage material that could make future batteries safer, more durable,...
Scientists print the world’s smallest infrared sensors—no silicon required
Engineers have created the smallest fully printed infrared light sensors ever made, opening a new path toward cheaper, smaller, and more flexible infrared technologies.
The...
How a theory of the universe helps us understand blood vessels, brains, and trees
For more than a hundred years, scientists have puzzled over a simple question: why do natural networks—like blood vessels, neurons, tree branches, and plant...
How a 400-year-old shark keeps its vision sharp for life
In a quiet office at the University of California, Irvine, Dorota Skowronska-Krawczyk watches a grainy video on her computer.
A massive Greenland shark drifts slowly...
A new study finds a subtle dance between dark matter and neutrinos
Time again for a tale of things dark and mysterious. A tale of dark matter. It's a well-told tale, but this time it involves...
Scientists make clean hydrogen from sunlight and water—no platinum needed
Hydrogen is often described as a dream fuel for a cleaner future. When it is used, it produces only water, not carbon dioxide.
But turning...
Grasshopper wings spark a new way for robots to glide
Sometimes scientific breakthroughs begin in unlikely places. For a team of engineers and entomologists from Princeton University and University of Illinois Urbana-Champaign, it started...

James Webb Space Telescope peers into the atmosphere of a puffy, fluffy exoplanet
Exoplanets are definitely a bit of a hot topic at the moment.
Throw in a sprinkling of the James Webb Space Telescope (JWST) and you...
Every bird has some dinosaur form, shows study
All baby birds have a moment prior to hatching when their hip bone is a tiny replica of a dinosaur’s pelvis.
That’s one of the...
What is the best radiation shielding for the surface of Mars
The planet Mars is calling to us.
At least, that is the impression one gets when examining all the planned and proposed missions to the...
Scientists develop new method to detect cancer cells faster
In a new study, researchers have developed a new technique to analyze proteins expressed on cancer cells.
The new technique shows promise in more rapidly...
Super-thin material could help make faster computers with less energy use
Computers may seem complicated, but at their core, they are really just made up of lots and lots of electronic switches.
These switches turn on...
