Sun's rotating 'magnet' pulls lightning towards UK
(Phys.org) —The Sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter the upper ...
Magnetic fields frozen into meteorite grains tell a shocking tale of solar system birth
The most accurate laboratory measurements yet made of magnetic fields trapped in grains within a primitive meteorite are providing important clues to how the early solar system evolved. The measurements point ...
New evidence for an exotic, predicted superconducting state
Superconductors and magnetic fields do not usually get along. But a research team led by a Brown University physicist has produced new evidence for an exotic superconducting state, first predicted a half-century ...
Fermi satellite finds hints of starquakes in magnetar 'storm'
(Phys.org) —NASA's Fermi Gamma-ray Space Telescope detected a rapid-fire "storm" of high-energy blasts from a highly magnetized neutron star, also called a magnetar, on Jan. 22, 2009. Now astronomers analyzing ...
Earth's magnetic field could flip within a human lifetime
Imagine the world waking up one morning to discover that all compasses pointed south instead of north.
UW fusion reactor concept could be cheaper than coal
Fusion energy almost sounds too good to be true – zero greenhouse gas emissions, no long-lived radioactive waste, a nearly unlimited fuel supply.
Sandia magnetized fusion technique produces significant results
(Phys.org) —Researchers at Sandia National Laboratories' Z machine have produced a significant output of fusion neutrons, using a method fully functioning for only little more than a year.
Nuclear spins control current in plastic LED: Step toward quantum computing, spintronic memory, better displays
University of Utah physicists read the subatomic "spins" in the centers or nuclei of hydrogen isotopes, and used the data to control current that powered light in a cheap, plastic LED – at room temperature ...
