Possibility of strange new particle surprises physicists
Last winter, physicists at the Large Hadron Collider detected hints of a particle beyond their wildest dreams. Soon they may learn if it’s real.

Dwarf galaxy spawned heavy elements
A study of nine stars in the dwarf galaxy Reticulum II found heavy elements. They had been produced after a violent stellar event sparked a chemical chain reaction.

How to make window ‘glass’ from wood
Scientists have come up with a way to make wood transparent. The new material could be used in everything from windows to packaging.

Sunlight + gold = steaming water (no boiling needed)
Nano-gold is the new black, at least when it comes to absorbing heat. When tiny gold particles get together, they become energy super-absorbers — turning them black.

Carbon dioxide could explain how geysers spout
A new study overturns 150 years of thinking about Yellowstone’s geysers. Carbon dioxide, not just hot water, may be driving those spectacular eruptions.

Smash hit: Making ‘diamond’ that’s harder than diamonds
Scientists had suspected extreme meteorite impacts might turn graphite into an unusual type of diamond. Now they’ve seen it happen — in under a nanosecond.
- Plants
Explainer: Some supplements may not have what it takes
Dietary supplements made from plants may not contain all of the chemicals that usually make a particular plant healthy for humans.

Food supplements can make you sick
Drugs must past safety testing before they can be sold. But food supplements don’t have to meet the same standards.

Olive oil untangles plastic
Vegetable oils can make plastic fibers stronger. And the process is safer and better for the environment than other detanglers.
- Brain
Males and females respond to head hits differently
Men and women are playing sports equally — and getting concussions in comparable numbers. But how their brains respond may differ greatly.
- Fossils
Clues to the Great Dying
Millions of years ago, nearly all life on Earth vanished. Scientists are now starting to figure out what happened.

Stephen Hawking says his group has solved a black hole puzzle
Physicist Stephen Hawking says light sliding along the outside of a black hole holds the key to understanding what’s inside.
