Liquid crystals controlled by magnetic fields may lead to new optical applications
Fusion, and friction, and fields! Oh, my! The rich and ubiquitous world of fluid dynamics
Graphene origami opens up new spintronics features
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 ...
Chandra X-ray Observatory finds planet that makes star act deceptively old
(Phys.org) —A planet may be causing the star it orbits to act much older than it actually is, according to new data from NASA's Chandra X-ray Observatory. This discovery shows how a massive planet can affect ...
Researchers discover new clues to determining the solar cycle
Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. The height of the sun's activity, known as solar maximum, is a time of numerous sunspots, ...
Researchers demonstrate ultra low-field nuclear magnetic resonance using Earth's magnetic field
Earth's magnetic field, a familiar directional indicator over long distances, is routinely probed in applications ranging from geology to archaeology. Now it has provided the basis for a technique which might, ...
On-chip topological light: First measurements of transmission and delay
Topological transport of light is the photonic analog of topological electron flow in certain semiconductors. In the electron case, the current flows around the edge of the material but not through the bulk. ...
