Realization of a new type of magnetic phase in devices opens the door to electronics based on topologically non-trivial materials A team of researchers at RIKEN and the University of Tokyo has demonstrated a new material that promises to eliminate loss in electrical power transmission. The surprise is that their methodology for solving this classic energy problem is based upon the first realization of a highly exotic type of magnetic semiconductor first theorized less than a decade ago - a...

On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth's magnetic field can also be connected with processes in the mantle. These are the research results presented by a group of geoscientists in the new advance edition of "Nature Geoscience" on Sunday, July 29th. The results show how the rapid processes in the outer core, which flows at rates of up to about one millimeter per...

Split Personality Star Discovered

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online One recently discovered star seems to have a split personality, with both a magnetar and pulsar consuming the object. The European Space Agency (ESA) said the newly discovered star appears to be a pulsar while hiding an intense internal magnetic field like a magnetar. The internal field is many times stronger than its external magnetic field, leading to its entry into the new class of "low-field...

Successful imaging of individual atoms and associated electric fields in ferroelectrics could lead the way to a new era of advanced electronics As scientists learn to manipulate little-understood nanoscale materials, they are laying the foundation for a future of more compact, efficient, and innovative devices. In research to be published online July 8 in the journal Nature Materials, scientists at the U.S. Department of Energy's Brookhaven National Laboratory, Lawrence Berkeley National...

Ultrafine Loops In The Sun's Corona
2012-06-13 15:31:07

A key to understanding the dynamics of the sun and what causes the great solar explosions there relies on deciphering how material, heat and energy swirl across the sun's surface and rise into the upper atmosphere, or corona. Tracking the constantly moving material requires state-of-the-art telescopes with the highest resolution possible. By combining images from NASA's Solar Dynamics Observatory (SDO) and a new generation telescope called the New Solar Telescope (NST) at Big Bear Solar...

Cancer Cells Could Be Sorted Using Tiny 'Speed Bump' Device
2012-06-12 15:38:13

In life, we sort soiled laundry from clean; ripe fruit from rotten. Two Johns Hopkins engineers say they have found an easy way to use gravity or simple forces to similarly sort microscopic particles and bits of biological matter -- including circulating tumor cells. In the May 25 online issue of Physical Review Letters, German Drazer, an assistant professor of chemical and biomolecular engineering, and his doctoral student, Jorge A. Bernate, reported that they have developed a lab-on-chip...

Process Linked To Northern Lights Observed

A University of Iowa researcher wants you to visualize a plate of spaghetti when you think of the northern lights. That´s because Jack Scudder, UI professor of physics and astronomy, and his colleagues have reached a milestone in describing how the northern lights work by way of a process called “magnetic reconnection.” The details are contained in a paper published in the June 5 issue of the journal Physical Review Letters; however, the process is best imagined as...

Successful test at PTB of optical magnetometer with potential applications in brain imaging for neurological diagnostics and in basic research. In future a new magnetic sensor the size of a sugar cube might simplify the measurement of brain activity. In the magnetically shielded room of Physikalisch-Technische Bundesanstalt (PTB) the sensor has passed an important technical test: Spontaneous as well as stimulated magnetic fields of the brain were detected. This demonstrates the potential...

Minute-scale interactions govern electronic behavior of superconductors with potential applications for voltage measurement techniques Researchers studying a superconducting strip observed an intermittent motion of magnetic flux which carries vortices inside the regularly spaced weak conducting regions carved into the superconducting material. These vortices resulted in alternating static phases with zero voltage and dynamic phases, which are characterized by non-zero voltage peaks in the...
