Some of the most sensitive methods of measuring magnetic fields use interactions of resonant light with atomic vapour. Recent developments in this vibrant field have led to improvements in ...

In 2018 and 2019, Nature Communications published Zhang’s two research papers about microswarm, which directs millions of nanoparticles in a rapidly oscillating magnetic field in bio-fluids.

Creatures from migratory eels and other fish species to insects to birds tap into the Earth’s magnetic field to navigate, sometimes many thousands of miles. But so far, evidence has been scant for any ...

Many different species—ranging from newts and insects to sea turtles, fish, and birds—are able to orient themselves relative to the Earth’s magnetic field. Among mammals, naked mole rats, deer, and ...

the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion. Over the past few decades, magnetic north’s movement has been unprecedented — it ...
