Warming the testicles using nanorods affects sperm production.
Growing applications of nanotechnology include using nanorods for male birth control. The technique has had some success in animals, and offers the potential of human male contraception.
We interact with nanoparticles in multiple ways every day. The nanoparticles in this illustration are delivering drugs to cells.
Some vaccine hesitancy is based on a fear of the nanoparticles used in mRNA vaccines. But humans have been interacting with nanoparticles for millennia, and we use nanotechnology-based devices every day.
Critics say investing in carbon capture and storage means betting on technology that’s not yet proven to work at scale. Using liquid marbles could make a huge difference.
Wildfire smoke contains a mixture of toxic pollutants that can be harmful to both the lungs and the brain.

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.
Nanotechnology, which approaches materials at the scale of atoms and molecules, has numerous applications for food production. Applying nanotech could revolutionize the agricultural sector.

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.
Nanoparticles dressed up in cell membranes snag SARS-CoV-2 virus particles before they reach human cells.
Nature and technology can combine to help farms of the future nourish the earth and its inhabitants.
We’re not powerless to change the future of food. Nature and technology can combine to nourish both the earth and its inhabitants.

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.
A nanotube innovation using waste plastic could help solve one of the world’s energy problems.
Nanoparticles occur naturally in some foods, and others have them added.
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.

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.
Nanomedicine could scupper the need for TB patients to take multiple daily tablets with toxic side effects.
The reason that nanoparticles hold such hope for TB treatment is that they can be carefully targeted.
There are countless nanoscopic architectures in nature, creating iridescence, sticky feet, magnetic navigation – and more.
