Could reusable ‘jelly ice’ cubes replace regular ice?
These hydrogel “jelly ice cubes” are made mostly of gelatin and water. They won’t melt, even when thawed, and may provide new food cooling options.
- Climate
Can scientists develop an icy sanctuary for Arctic life?
The final refuge for summer sea ice may also protect the creatures that depend on it. Saving it is an ambitious goal with many hurdles.

This glitter gets its color from plants, not a synthetic plastic
In the new material, tiny arrangements of cellulose reflect light in specific ways to create vibrant hues in an environmentally friendly glitter.

From icebergs to smoke, forecasting where dangers will drift
Smoke drifts. Fish eggs float downstream. Where such drifting things end up may seem a mystery. But research can predict where they’ll end up.
- Microbes
Genes point to how some bacteria can gobble up electricity
A new study shows how some microbes absorb and release electrons — a trait that may point to new fuels or ways to store energy.

Easy for you, tough for a robot
Robots still can’t do many things that we find easy. Can engineers reduce how klutzy robots are and boost their common sense?
- Physics
Future cars may offer personal sound zones — no earphones needed
Zones that offer each passenger personal listening are closer to reality. A new design improves performance by adapting to the conditions in your car.

Researchers role-played as Neandertals to learn how they hunted birds
By pretending to be Neandertals, researchers show that the ancient hominids likely had the skills to hunt crowlike birds called choughs.

Analyze This: Hardened wood can make sharp steak knives
Researchers treated wood to make it hard and dense. Out of it, they carved sharp knives and nails that could substitute for ones made of steel.

Ask the experts: How to create a top-notch science fair project
Five finalists in the Broadcom MASTERS middle-school competition reveal how they created nationally competitive projects.
- Animals
What biologists call a species is becoming more than just a name
The tree of life — evolution — has been reshaping how scientists name and classify organisms. Some want naming to reflect evolutionary groups even more.

Chemists win Nobel Prize for faster, cleaner way of making molecules
Both scientists independently came up with new process — asymmetric organocatalysis. That name may be a mouthful, but it’s not that hard to understand.
