A Tiny Throat Bone Just Proved Nanotyrannus Was Its Own Dinosaur Species
For decades, scientists debated whether Nanotyrannus was a separate dinosaur or just a teenage T. rex. A microscopic look at a rarely studied bone has finally settled the argument — and the answer changes how we understand prehistoric ecosystems.
T. rex Had Tiny Arms Because Its Jaw Did All the Work
A new study reveals why T. rex and at least four other groups of dinosaurs evolved smaller and smaller arms over millions of years — and the answer starts with their incredibly powerful heads.
The 31-Foot "Super Croc" That Hunted Dinosaurs Now Has Its First Full Skeleton on Display
A scientist spent over 40 years hunting fossils of a prehistoric crocodilian bigger than a school bus — and now the first life-size replica of its complete skeleton is on display at a Georgia museum.
Your Body Is Mostly Empty Space — and the Math Behind That Fact Is Wild
Scientists say every human on Earth could be compressed to the size of a sugar cube if all the empty space were removed from our atoms. The math checks out, and the physics behind it reveals something strange about everything you have ever touched.
Blue Skies and Red Sunsets Are the Same Science — Here Is How It Works
Blue skies and fiery sunsets might look completely different, but they're both caused by the exact same thing happening to light as it travels through air.
The Ancient Merger That Powers Almost Every Living Thing on Earth
Around two billion years ago, one tiny cell swallowed another — and instead of becoming a meal, the smaller cell became a permanent partner. That partnership now powers almost every living thing on Earth.
Nine Brains, Three Hearts, Blue Blood: How the Octopus Body Actually Works
Octopuses are built unlike almost any other animal on Earth. Their arms can taste and react independently, their blood is blue, and they run on three hearts — and the science behind it all is even wilder than it sounds.
Bees Have Brains Smaller Than a Sesame Seed — and They Can Still Do Math
New research from Australia confirms that honeybees can count and reason with numbers in ways scientists once thought impossible for such tiny creatures. The findings could even change how we build artificial intelligence.
Fish Make Their Own Sunscreen — Now Scientists Are Getting Bacteria to Do It Too
A natural UV-blocking compound found in fish could become the key ingredient in future eco-friendly sunscreens, thanks to scientists who figured out how to get E. coli bacteria to produce it in large quantities.
How Oyster Glue Could Lead to Stronger and Greener Concrete
Engineers at Purdue University are taking inspiration from oysters, which produce their own underwater cement, to create a stronger and more eco-friendly alternative to traditional concrete.
A Fossilized Voice Box Is Changing What Scientists Think Dinosaurs Sounded Like
An 80-million-year-old voice box from an armored dinosaur is giving researchers their first real clues about how these ancient animals actually communicated — and the answer is surprisingly birdlike.
The Axolotl Can Rebuild Its Own Brain — Here Is How Scientists Think It Works
With feathery gills and a permanent smile, the axolotl looks harmless. But this little salamander holds one of biology's biggest mysteries: the ability to regenerate parts of its own brain.
