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