Gas-giant planets orbiting close to other stars have powerful magnetic fields, many times stronger than our own Jupiter, according to a new study by a team of astrophysicists. It is the first time the ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

The mystery of how birds migrate long distances over land and sea is a step closer to being cracked. By studying robins, scientists have found clues to how birds sense the Earth's magnetic field. Just ...

We may finally know the secret to how migrating birds can sense Earth’s magnetic fields: a molecule in their eyes called cryptochrome 4 that is sensitive to magnetism, potentially giving the animals ...

Just as you might reach for a magnetic compass to find which way is north or south, birds are thought to have an in-built "living compass". A chemical in the eye that is sensitive to magnetism could ...

Archaeologists traditionally rely on finding organic remains for radiocarbon dating to pinpoint new finds in time, but often these are not found on sites dating over 5,000 years ago. As a result, ...
