The Earth's center is 1,000 degrees hotter than previously thought

Scientists have determined the temperature near the Earth's centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature ...

Unexpectedly Long-Range Effects in Advanced Magnetic Devices

(PhysOrg.com) -- A tiny grid pattern has led materials scientists at the National Institute of Standards and Technology (NIST) and the Institute of Solid State Physics in Russia to an unexpected finding—the surprisingly ...

Scientists discover a process that stabilizes fusion plasmas

Scientists seeking to bring the fusion reaction that powers the sun and stars to Earth must keep the superhot plasma free from disruptions. Now researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics ...

Study says salmon may use magnetic field as navigational aid

The mystery of how salmon navigate across thousands of miles of open ocean to locate their river of origin before journeying upstream to spawn has intrigued biologists for decades, and now a new study may offer a clue to ...

Higher plasma densities, more efficient tokamaks

When the density of the hot, ionized gas (known as a plasma) in a tokamak exceeds a certain limit, it usually leads to a rapid loss of heat and plasma currents. The currents are required to confine the plasma. Such events ...

A turbulent solution to a growing problem

A recent experiment lead by University of California, Los Angeles (UCLA), researchers on the DIII-D tokamak suggests that plasma turbulence can prevent filamentary structures called magnetic islands from growing so large ...

Discovery of a new confinement state for plasma

The National Institutes of Natural Sciences National Institute for Fusion Science applied the "Momentary Heating Propagation Method" to the DIII-D tokamak device operated for the United States Office of Science, Department ...
