Dynamic tattoos promise to warn wearers of health threats

Researchers are developing tattoo inks that do more than make pretty colors. Some can sense chemicals, temperature and UV radiation, setting the stage for tattoos that diagnose health problems.

Quantum dots that light up TVs could be used for brain research

These tiny nanoparticles might provide a new way to see what's happening in the brain and even deliver treatments to specific cells – if researchers figure out how to use them safely and effectively.

World hunger has risen for three straight years, and climate change is a cause

After declining for nearly a decade, the number of hungry people in the world is growing again. Climate change, which is disrupting weather patterns that farmers rely on, is a major cause.

Why nanotechnology is more than just a buzzword

Nanotechnology brings together multiple science disciplines to create devices that mimic the refinements of nature. It’s difficult – and exhilarating.

The BS and the science of nanotechnology

Last week, Elon Musk 'called BS' on nanotechnology. And it threw up an important question: just what is nanotech, and is it more hype than science?

Silver nanoparticles in clothing wash out – and may threaten human health and the environment

Many socks, towels and other textiles are treated with silver nanoparticles to kill germs and odors. When the silver washes out, it can pollute waterways. Two chemists propose a way to collect it from wastewater.
