MIT's Swallowable Sensor Could Replace Thermometers by Reading Your Temp from Inside
A new berry-sized sensor developed at MIT can travel through your digestive system and send continuous, highly accurate temperature readings to doctors — no thermometer required.
Scientists Finally Complete the Millipede Family Tree — and It Goes Back 460 Million Years
Long before dinosaurs, trees, or any backboned animal set foot on land, millipedes were already thriving. A new study has filled in the last missing pieces of their evolutionary history — and the discoveries are stranger and more impressive than anyone expected.
Scientists Created a Material Inspired by Staples That Can Lock Solid or Fall Apart in Seconds
Researchers at CU Boulder discovered that staple-shaped particles can tangle together into a surprisingly strong material — and then unravel just as fast using vibrations. The discovery could change how we build structures and design robots.
Parrots May Use Names to Identify Specific Individuals, Study Finds
New research on hundreds of pet parrots reveals that some birds use names to refer to particular people or animals — and a few even use their own name to grab attention.
Science Explains Why Cats Watch You Struggle While Dogs Actually Help
A new study compared cats, dogs, and toddlers to see who would help a person in need — and the results reveal a fascinating difference in how these species are wired.
The Truth Behind Superfoods: Real Nutrition or Just Smart Marketing?
Foods like blueberries, salmon, and kale get labeled “superfoods,” but what does that word actually mean — and is it backed by science? The answer is more interesting than you might expect.
Bananas Are Scientifically Berries, but Strawberries Are Not — Here Is Why
The fruits you call berries are probably not berries at all, and the ones you would never guess actually are. Plant scientists have a very specific definition, and it changes everything.
Earth's Core Is as Hot as the Sun's Surface — Here's How Scientists Know
Nobody has ever visited Earth's core, yet scientists have figured out it reaches temperatures of up to 10,000 degrees Fahrenheit. The clever techniques they used to discover this are just as fascinating as the discovery itself.
Scientists Solved the Mystery of Where Potatoes Actually Came From
A new genetic study reveals that potatoes were born from an ancient hybridization event between the ancestors of tomatoes and a lesser-known South American plant group — and it happened nearly 9 million years ago.
Scientists Discover That Echidnas Evolved from a Water-Dwelling Ancestor
A 108-million-year-old arm bone is rewriting everything scientists thought they knew about how echidnas — spiny, egg-laying mammals — came to live on land.
MOXIE Made Oxygen on Mars — Here Is Why That Small Machine Is a Giant Deal
A microwave-sized device aboard NASA's Perseverance rover spent two years quietly making breathable air on Mars, proving a technology that could one day bring astronauts home from the red planet.
Spinning Black Holes Might Actually Send Messages Back in Time
A new study inspired by the film Interstellar explores how information could travel backward through time using exotic loops in spacetime near spinning black holes. The physics is real, even if the idea feels like science fiction.
