Antarctic lava yields clues to Earth's past magnetic field

The movement of molten metals in Earth's outer core generates a vast magnetic field that protects the planet from potentially harmful space weather. Throughout Earth's history, the structure of the magnetic field has fluctuated. ...

Magnetic memories of a metal world

4.5 billion years ago in the violent, high-speed environment of the early solar system, a protoplanet roughly the size of Mars was involved in a series of fierce collisions with other large planetary bodies.

Micromotors get supercharged with three 'engines'

Someday, microscopic robots could perform useful functions, such as diagnostic testing in lab-on-a-chip sensors, micropatterning surfaces or repairing equipment in tight spaces. But first, scientists need to be able to tightly ...

A direct view on spin-waves

Spin-waves are promising candidates for future information processing schemes as there is almost no frictional heating in magnetic transport. Information encoding, however, is only possible in spin-wave packets. A group of ...

CLASP-2: Investigating the magnetic solar chromosphere

Four years ago, an international team (USA, Japan and Europe) carried out an unprecedented suborbital space experiment called CLASP-1, motivated by theoretical investigations carried out at the IAC by Javier Trujillo Bueno ...
