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.

Zap! Laser tattoos could create electronics to eat or wear
Lasers can tattoo a nontoxic form of carbon onto everyday items. This one day could lead to wearable — even edible — electronics.

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.

New ‘tattoo’ could lead to drought-tolerant crops
Scientists create stick-on 'plant tattoo.' It measures how efficiently crops use water, a key to better identifying breeding stock for more drought-resistant crops.

Cool Jobs: Drilling into the secrets of teeth
A bioengineer, a biologist and an archaeologist all study teeth to explore new materials, to grow better tissues and to learn more about prehistoric humans.
