I-mode powers up on alcator C-mod tokamak

A key challenge in producing fusion energy is confining the plasma long enough for the ionized hydrogen to fuse and produce net power. Suppressing plasma turbulence is one approach to this, but the resulting increase in energy ...

NASA'S NPP satellite acquires first ATMS measurements

The Advanced Technology Microwave Sounder (ATMS) on board NASA's newest Earth-observing satellite, NPP, acquired its first measurements on November 8, 2011. The image shows the ATMS channel 18 data, which measures water vapor ...

Feeling the heat: 30 tons of fine control for fusion plasmas

A major upgrade to the DIII-D tokamak fusion reactor operated by General Atomics in San Diego will enable it to develop fusion plasmas that can burn indefinitely. Researchers installed a movable, 30-ton particle-beam heating ...

Tokamak experiments come clean about impurity transport

A fusion reactor operates best when the hot plasma inside it consists only of fusion fuel (hydrogen's heavy isotopes, deuterium and tritium), much as a car runs best with a clean engine. But fusion fuel reactions at the heart ...

A new spin on understanding plasma confinement

To achieve nuclear fusion for practical energy production, scientists often use magnetic fields to confine plasma. This creates a magnetic (or more precisely "magneto-hydrodynamic") fluid in which plasma is tied to magnetic ...

New turkey feed helps bird producers gobble up profits

As feed prices have risen in recent years, feeding turkeys has become more costly than many producers can bear. Satisfying turkeys' hunger accounts for 70 percent of the cost of producing turkey meat. Now, a researcher at ...

New study shows very first stars not monstrous

(PhysOrg.com) -- The very first stars in our universe were not the behemoths scientists had once thought, according to new simulations performed at NASA's Jet Propulsion Laboratory, Pasadena, Calif.
