For the first time, researchers have demonstrated a means of controlling cell functions with a physical, rather than chemical, signal. Using a magnetic field to pull together tiny beads targeted to ...

Magnets could be a tool for directing stem cells' healing powers to treat conditions such as heart disease or vascular disease. By feeding stem cells tiny particles made of magnetized iron oxide, ...

One of the most remarkable “sixth” senses in the animal kingdom is magnetoreception – the ability to detect magnetic fields – but exactly how it works remains a mystery. Now, researchers in Japan may ...

Researchers infused antibody-studded iron nanoparticles into the bloodstream to treat heart attack damage. The combined nanoparticle enabled precise localization of the body’s own stem cells to the ...

A new study suggests that to meld living cells with the digital world, think of them as you would a refrigerator door—a handy place to stick magnets. Researchers report in Nature Nanotechnology that ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Many animals are known to navigate by sensing the Earth’s ...
