Do you have a magnetic compass in your head?
Your brain's sensory talents go way beyond those traditional five senses. A team of geoscientists and neurobiologists explored how the human brain monitors and responds to magnetic fields.
Magnetotactic bacteria owe their special property to the magnetic nanoparticles they contain.
These single-celled organisms naturally respond to the Earth's weak magnetic field. Scientists are untangling how it all works, looking to future biomedical and other engineering applications.
Color-changing cells in an Atlantic squid’s skin contain light-sensitive pigments.
We're used to thinking of our eyes detecting light as the foundation of our visual system. But what's going on in other cells throughout the body that can detect light, too?
The invisible force and visible effects of magnetism.
