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...

redOrbit Staff & Wire Reports - Your Universe Online Electromagnetic noise from AM broadcast signals (or "electrosmog") could be interfering with the migratory flight paths of birds by disrupting the animals' "internal compass,” German researchers reported this week in the journal Nature. "At first, I was highly skeptical that this could be the explanation. But if you have seemingly unlikely effects then the proof needs to be much stronger - and that is why we have done so many...

Swarm Satellites Precise Sense Of Magnetism
2014-05-08 03:26:09

ESA Although they were launched only five months ago, ESA’s trio of Swarm satellites are already delivering results with a precision that took earlier missions 10 years to achieve. Engineers have spent the last five months commissioning the identical satellites and carefully guiding them into their orbits to provide the crucial measurements that will unravel the mysteries of Earth’s magnetic field. Swarm has a challenging task ahead. Together, the satellites will measure and...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Neutron stars – also called pulsars for the way they send pulses of light across the Universe due to their high spin rates – are some of the most dynamic objects in the Universe, characterized by incredibly compact dimensions, focused beams of radiation, and incredible surface gravity. Additionally, these rapid rotators possess the strongest magnetic fields known to man – billions of times more powerful than anything ever...
