Earth ate a Mercury-like body early in its history, study finds
A Mercury-like body smashed into a young Earth and gave our planet's core the radioactive elements necessary to generate a magnetic field, two Oxford geochemists say.
Comet springs surprise: Rosetta and Philae find Comet 67P not magnetised
Measurements made by Rosetta and Philae during the probe's multiple landings on Comet 67P/Churyumov-Gerasimenko show that the comet's nucleus is not magnetised.
Long-sought magnetic mechanism observed in exotic hybrid materials
Scientists have measured the subatomic intricacies of an exotic phenomenon first predicted more than 60 years ago. This so-called van Vleck magnetism is the key to harnessing the quantum quirks of topological ...
Magnetic-field detector is 1,000 times more efficient than its predecessors
MIT researchers have developed a new, ultrasensitive magnetic-field detector that is 1,000 times more energy-efficient than its predecessors. It could lead to miniaturized, battery-powered devices for medical ...
Frustrated magnets: New experiment reveals clues to their discontent
An experiment conducted by Princeton researchers has revealed an unlikely behavior in a class of materials called frustrated magnets, addressing a long-debated question about the nature of these discontented ...
As stars form, magnetic fields influence regions big and small
Stars form when gravity pulls together material within giant clouds of gas and dust. But gravity isn't the only force at work. Both turbulence and magnetic fields battle gravity, either by stirring things ...

Using magnetic fields to understand high-temperature superconductivity
Taking our understanding of quantum matter to new levels, scientists at Los Alamos National Laboratory are exposing high-temperature superconductors to very high magnetic fields, changing the temperature ...
Landmark study proves that magnets can control heat and sound
Researchers at The Ohio State University have discovered how to control heat with a magnetic field.
Astronomers reveal supermassive black hole's intense magnetic field
Astronomers from Chalmers University of Technology have used the giant telescope Alma to reveal an extremely powerful magnetic field very close to a supermassive black hole in a distant galaxy. The results ...
On the road to spin-orbitronics: Researchers find new way to manipulate magnetic domain walls
Few among us may know what magnetic domains are but we make use of them daily when we email files, post images, or download music or video to our personal devices. Now a team of researchers at the U.S. Department ...
Plant cell structure discovery could lead to improved renewable materials
The step forward follows research by the Universities of Warwick and Cambridge and the unexpected discovery of a previously unknown arrangement of molecules in plant cell walls.
Heart of the black auroras revealed by Cluster
Most people have heard of auroras - more commonly known as the Northern and Southern Lights - but, except on rare occasions, such as the recent widespread apparition on 17 March, they are not usually visible ...
Ecological 'flash mobs': It's all about timing... and magnets?
How does an acorn know to fall when the other acorns do? What triggers insects, or disease, to suddenly break out over large areas? Why do fruit trees have boom and bust years?
