Researchers turned white blood cells called neutrophils into drug-smuggling “neutrobots,” which penetrated the blood-brain barrier to treat brain cancer in mice.

The effects seem to be mediated by a reactive oxygen species in the animals’ livers.

When the sun’s atmosphere is stormy, more whales end up on the beach, according to a new study. Biologists speculate it may have to do with navigation or health.

The time period, which spans 770,000 to 126,000 years ago, started with a reversal of the planet’s magnetic field.

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.
