Penetrating the quantum nature of magnetism

Antiferromagnets are materials that lose their apparent magnetic properties when cooled down close to absolute zero temperature. Different to conventional magnets, which can be described with classical physics even at the ...

Stratospheric aerosols and their impact on Sahelian rainfall

(Phys.org) —The Sahelian drought of the 1970s-1990s was one of the largest humanitarian disasters of the last fifty years, causing up to 250,000 deaths and creating 10 million refugees. This drought has been attributed ...

Superfast model brain to predict flooding during heavy rain

(Phys.org) —Heavy rain has one again resulted in widespread flooding across the country. With climate change likely to cause further severe weather events in the coming years, methods of quickly predicting flooding will ...

Solar storm near Earth caused by fast CME

On March 17, 2013, at 1:28 a.m. EDT, the coronal mass ejection (CME) from March 15 passed by NASA's Advanced Composition Explorer (ACE) as it approached Earth. Upon interacting with the giant magnetic bubble surrounding Earth, ...

Predictability: The brass ring for synthetic biology

(Phys.org) —Predictability is often used synonymously with "boring," as in that story or that outcome was soooo predictable. For practitioners of synthetic biology seeking to engineer valuable new microbes, however, predictability ...

NASA transfers operational control of environmental satellite

The Suomi National Polar-orbiting Partnership (NPP) satellite, a partnership between NASA and the National Oceanic and Atmospheric Administration (NOAA), was transitioned to NOAA operational organization control Feb. 22, ...

Earth-directed CME released by long duration solar flare

(Phys.org)—On Feb. 9, 2013 at 2:30 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME, associated with a long duration C2.4-class flare. Experimental NASA research models, based on observations ...
