If The Earth's Magnetic Field Flipped Now, What Would The Impacts Be?

April Flowers for redOrbit.com - Your Universe Online Imagine waking up after a night of camping to find that your compass is pointing south rather than north. It can happen. The magnetic field around Earth has flipped before — though not...

Patrick Regan, Technische Universitaet Muenchen Electrical engineers at the Technische Universität München (TUM) have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on three-dimensional arrangements of nanometer-scale magnets instead of transistors. As the main enabling technology of the semiconductor industry – CMOS fabrication of silicon chips – approaches fundamental limits, the TUM...

Chuck Bednar for redOrbit.com - Your Universe Online Add dolphins to the list of species that are sensitive to magnetic stimuli, as a new study published Tuesday in Naturwissenschaften – The Science of Nature revealed that the creatures alter their behavior when swimming near magnetized objects. Lead author Dorothee Kremers of the Université de Rennes in France and her colleagues made their discovery while conducting research in the delphinarium of Planète Sauvage, and they claim...

plasma during magnetic reconnection
2014-09-14 02:30:26

John Greenwald, Princeton Plasma Physics Laboratory Magnetic reconnection can trigger geomagnetic storms that disrupt cell phone service, damage satellites and blackout power grids. But how reconnection, in which the magnetic field lines in plasma snap apart and violently reconnect, transforms magnetic energy into explosive particle energy remains a major unsolved problem in plasma astrophysics. Magnetic field lines represent the strength and direction of magnetic fields. Now scientists...

Rachel Berkowitz, Berkeley Lab Earth’s magnetic field, a familiar directional indicator over long distances, is routinely probed in applications ranging from geology to archaeology. Now it has provided the basis for a technique which might, one day, be used to characterize the chemical composition of fluid mixtures in their native environments. Researchers from the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) conducted a proof-of-concept NMR...

Wiezmann Institute of Science Competing forces coax nanocubes into helical structures Nanocubes are anything but child’s play. Weizmann Institute scientists have used them to create surprisingly yarn-like strands: They showed that given the right conditions, cube-shaped nanoparticles are able to align into winding helical structures. Their results, which reveal how nanomaterials can self-assemble into unexpectedly beautiful and complex structures, were recently published in Science....

Sensima is a pre-revenue, developer of magnetic sensor technologies for angle measurements as well as three-dimensional magnetic field sensing. Sensima's patented magnetic angle sensors are used in rotary...

Magnetic Fields Counteract The Forces Of Supermassive Black Holes
2014-06-05 11:37:47

Brett Smith for redOrbit.com - Your Universe Online A supermassive black hole sits at the center of most galaxies and a new study published in the journal Nature has found that super-powerful magnetic fields can have influence near and even counteract the forces of these black holes. "This paper for the first time systematically measures the strength of magnetic fields near black holes," said study author Alexander Tchekhovskoy, an astronomer at the University of California, Berkeley....

Oregon State University Exposure to iron pipes and steel rebar, such as the materials found in most hatcheries, affects the navigation ability of young steelhead trout by altering the important magnetic "map sense" they need for migration, according to new research from Oregon State University. The exposure to iron and steel distorts the magnetic field around the fish, affecting their ability to navigate, said Nathan Putman, who led the study while working as a postdoctoral researcher...

Supernova Recreation Reveals How Interstellar Magnetic Fields May Have Formed
2014-06-02 10:03:18

Brett Smith for redOrbit.com - Your Universe Online Using a laser beam 60,000 billion times more powerful than a typical laser pointer, researchers have recreated a small-scale supernova and revealed that cosmic turbulence may have boosted magnetic fields to the power seen in interstellar space, according to a new report in the journal Nature Physics. "Magnetic fields are ubiquitous in the universe," said study author Don Lamb, a professor in astronomy and astrophysics at the University...
