Pollution from more frequent floods and wildfires – exacerbated by the warming climate – is threatening human health and poses particular risks to the brain.
The NanoMslide causes potentially cancerous cells to ‘light up’ with vivid colour contrast. It has already been successful in finding early-stage breast cancer cells in human tissue.
Nanotechnology can improve farming efficiency without the need for new infrastructure.

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.
Bricks turn out to be useful for storing electricity thanks to their porousness and red pigment.
Duck decoys lure real ducks within range of hunters. Nanoparticles that look like cells serve as both decoys and hunters to ensnare virus particles.

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.
Nanoparticles are extremely tiny particles, with external dimensions smaller than 100 nanometres (0.0001 of a millimetre). Here’s what we know about nanotechnology in food.
