Enceladus plume is a new kind of plasma laboratory

(Phys.org) -- Recent findings from NASA's Cassini mission reveal that Saturn's geyser moon Enceladus provides a special laboratory for watching unusual behavior of plasma, or hot ionized gas. In these recent findings, some ...

An unlikely route to ferroelectricity

(Phys.org) -- Ferroelectricity, which was first observed in the 1940s, is an interesting phenomenon involving the spontaneous (non-induced) formation of charge polarization (separation of charge) in certain materials. This ...

Vikings could have steered by polarized light

(PhysOrg.com) -- The Vikings are said to have been able to navigate with the aid of "sunstones" that allowed them to see the sun on cloudy or foggy days. Now scientists in Hungary and Sweden say the sunstones could have been ...

Spin polarization achieved in room temperature silicon

(PhysOrg.com) -- A group in The Netherlands has achieved a first: injection of spin-polarized electrons in silicon at room temperature. This has previously been observed only at extremely low temperatures, and the achievement ...

Researchers set alarm for incoming space storms

(PhysOrg.com) -- A team of researchers at the University of Alberta in Edmonton has broken new ground in outer space by pinpointing the impact epicentre of an Earthbound space storm as it crashes into the atmosphere and giving ...

Good prospects for altermagnets in spin-based electronics

Altermagnets represent a newly recognized class of materials in magnetism that could enable novel applications in spin-based electronics. Their magnetically ordered state consists of an antiparallel arrangement of microscopic ...

Magnetic launch of black hole jets in Perseus A

The Event Horizon Telescope collaboration, including scientists from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has recently resolved the jet base of an evolving jet of plasma at ultra-high angular resolution.
