What happened when Earth’s magnetic shield collapsed 41,000 years ago? A new study suggests that this dramatic event, known as the Laschamps Excursion, may have pushed early humans to adapt in ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

For most of modern science, humans were believed to lack any ability to sense Earth’s magnetic field. Magnetoreception was considered a specialised adaptation found in migratory birds, sea turtles, ...

Wandering magnetic fields would have had noticeable effects for humans. Maximilian Schanner (GFZ Helmholtz Centre for Geosciences, Potsdam, Germany) When we first got together, we wondered whether our ...

As an electromagnetic radiation phenomenon, it’s perhaps not so surprising that light is affected by a magnetic field. This Faraday effect (FE) has been used since its discovery by [Michael Faraday] ...

Radio waves from cellphones and Wi-Fi are invisible. The electromagnetic fields emitted by electronic devices are as well.

The universe's first magnetic fields may have been much weaker than we first imagined — and were roughly equivalent to the strength of the magnetic activity within the human brain, according to a new ...
