To witness maximum pressure, peek inside a proton
Scientists used experimental data to estimate the pressures inside a proton. And surprise: Its mega-big — the greatest known!

The plant world has some true speed demons
Some plants can fling, snap and hop at dizzying speeds. Such botanical gymnastics gives lie to the idea that all plants are slow, boring stick-in-the-muds.

This plastic can be recycled over and over and over
A new kind of plastic is fully recyclable: Unlike current plastics, it breaks down into the exact same molecules from which it was made.

Light-sensitive ‘ink’ gives 4-D printing more wiggle room
Many 4-D-printed objects can flex and change their shape. A new “ink” and printing method now gives them greater range of motion.

Small swimmers may play huge role in churning the seas
Hoards of migrating shrimp and krill can cause large-scale water movements in the ocean, a new study suggests.

New black hair dye uses no harsh chemicals
Scientists have developed a new black-carbon-based hair dye. Instead of using damaging chemicals to dye hair, flexible flakes of carbon coat each strand.

In a colony, king penguins act like a liquid
Is this a living liquid? King penguins move around within their colonies, clearing out some space, and then refilling it. That behavior resembles a liquid, scientists conclude.

An ancient plant inspires a new lab tool
Researchers have designed a lab tool that moves liquids from one place to another by mimicking a plant called a liverwort.

Hard-to-burn ‘smart’ wallpaper even triggers alarms
Scientists have made wallpaper that won’t easily burn. And embedded nanowires can be linked to a sensor to sound an alarm when the paper gets too hot.

Light could make some hospital surfaces deadly to germs
A new surfacing material can disinfect itself. Room lighting turns on this germ-killing property, which could make the material attractive to hospitals.

Star Wars‘ cutest droids would get stuck on the beach
On screen, R2D2 and BB-8 travel over every type of terrain. But in real life, any sandy path would stop these droids short.
