Fast-flowing electrons may mimic astrophysical dynamos

A powerful engine roils deep beneath our feet, converting energy in the Earth's core into magnetic fields that shield us from the solar wind. Similar engines drive the magnetic activity of the sun, other stars and even other ...

Field-responsive mechanical metamaterials (FRMMs)

In a recent study published in Science Advances, materials scientists Julie A. Jackson and colleagues presented a new class of materials architecture called field-responsive mechanical metamaterials (FRMM). The FRMMs exhibit ...

Ancient lunar dynamo may explain magnetized moon rocks

The presence of magnetized rocks on the surface of the moon, which has no global magnetic field, has been a mystery since the days of the Apollo program. Now a team of scientists has proposed a novel mechanism that could ...

Improved waste separation using super-stable magnetic fluid

Magnetically separating waste particles makes it possible to reclaim a variety of raw materials from waste. Using a magnetic fluid, a waste flow can be separated into multiple segments in a single step. Researchers from Utrecht ...
