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.

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.

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.

Electricity sensor harnesses a shark’s secret weapon
A new “quantum” material mimics the sensors that help a shark sense its prey. Like a shark, it can detect tiny electric fields.

Moisture unmasks camouflaged message
Researchers have developed a new type of chemical that will mask some hidden message — until you add water.

Hairy nanoparticles put viruses in a deadly embrace
Current drugs can’t stop viruses for good. But newly developed hairy nanoparticles just might. They surround and put pressure on the viruses, which ultimately destroys them.
