Scientists Say: Zirconium
Zirconium is a metal that knows the meaning of tough. It’s so heat resistant that it’s used for molds to shape melted metals, and so radiation resistant that it coats nuclear reactors.

This bandage uses electrical zaps to heal wounds faster
Scientists have invented a bandage that helps wounds heal faster by zapping them with electricity. The patient’s own motions power this device.

This rewritable paper depends on disappearing ink
Scientists have made a new rewritable paper that can hold text and images for at least six months. It also can be reused more than 100 times.

Some plastics learn to repair themselves
A new material can fix its own scratches and small cracks. One day, it also may make self-healing paints and plastics possible.

Super-water-repellent surfaces can generate energy
Scientists knew they could get power by running salt water over an electrically charged surface. But making that surface super-water-repellent boosts that energy production, new data show.

Soft robots get their power from the skin they’re in
A flexible electronic “skin” embedded with air pouches or coils can wrap around inanimate objects, turning them into handy robots.

Adhesive from trees could make tape more eco-friendly
The stuff that makes your tape sticky comes from fossil fuels. Now scientists have used tree wastes to engineer a “greener” tape adhesive — one kinder to the environment.

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.

Photons map the atomic scale to help medicine and more
At a big lab outside Chicago, a gigantic beam of speedy electrons is helping researchers fight diseases, build better electronics and more.

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.

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.

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.
