Largest-ever Magnetic Field Found Around Massive Star
2012-09-12 06:10:56

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have measured the largest-ever magnetic field around a massive star and reported their findings in the journal Monthly Notices of the Royal Astronomical Society. The team used the Hobby-Eberly Telescope (HET) at The University of Texas McDonald Observatory and the Canada-France Hawaii Telescope (CFHT) on Hawaii's Mauna Kea to determine that the star's magnetic field is 20,000 times stronger than the Sun's. The magnetic...

Researchers reproduce plasma loops to help understand solar physics In orbit around Earth is a wide range of satellites that we rely on for everything from television and radio feeds to GPS navigation. Although these spacecraft soar high above storms on Earth, they are still vulnerable to weather–only it's weather from the sun. Large solar flares–or plasma that erupts from the sun's surface–can cause widespread damage, both in space and on Earth, which is why researchers...

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
2012-07-16 14:42:45

[ 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...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
