Prehistoric ‘sea’ monster also lurked in rivers, data show
A 66-million-year-old fossil tooth turned up alongside remains of a T. rex and ancient crocodile. This shows some mosasaurs roamed into rivers.

You need to eat protein — but the right mix really matters
All proteins are not equal, research is showing. So while most Americans get plenty of protein, they might not be eating the most nutritious blend.

Explainer: What is chirality?
Chiral molecules are mirror images of each other. They might not seem all that different — but can have drastically different effects in medicine, materials and more.

As winters warm, athletes must cope with harder snow and tricky ice
Ice arenas and artificial snow now dominate the winter Olympics. Athletes there — and everywhere — may need to adjust how they train and perform.

‘Stenciling’ tiny gold particles gives them new properties
Decorating nanoparticles with other chemicals could give them useful properties for medicines, textiles and more.

Scientists finally know why ice is so slippery
It’s not because ice heats up and then partially melts. Rather, ice changes at the molecular level — a process scientists have finally modeled.

Rudolph’s red nose could glow through bioluminescence
Simple chemistry could give the reindeer his iconic red snout. But physics would make it look different colors to anyone who spied Rudolph from the ground.

Ants are the secret ingredient to this tasty yogurt
The traditional yogurt-making technique was once popular in parts of Europe and Asia. But don’t try this at home!

New materials yank ‘forever chemicals’ from water
Materials known as metal-organic frameworks, or MOFs, trap some PFAS fast — and can be reused again and again.

Structures that work like Hermione’s magic handbag land a chemistry Nobel
Richard Robson, Susumu Kitagawa and Omar Yaghi developed these metal-organic frameworks, which can trap pollutants, collect water from air and more.

New theory may at last explain a swamp’s ghostly will-o’-the-wisps
Chemists have spotted tiny zaps of electricity moving between “swamp-gas” bubbles. Could they ignite methane gas to glow as dancing blue flames?
