Glass eels form a magnetic memory of their estuaries’ currents in order to migrate.

The new work calls into question the idea that neurons can be genetically engineered to fire in response to magnetic fields, a setback for the budding technique.

Meet the University of Toronto’s Yu Sun, whose work developing magnetic tweezers is featured in our Modus Operandi column.

Microscope-mounted magnets with computerized feedback control allow precision manipulations of intracellular objects.

Optimized tweezers enable precise 3-D manipulations of a cell’s organelles.

A study of people’s brainwaves hints at their unconscious ability to perceive the Earth’s magnetic field.

At magnetic field intensities somewhat above that of Earth, stem cell proliferation shifts gears.
