Physicists pay homage to the SQUID at 50
From humble beginnings in a series of accidental discoveries, SQUIDs have invaded and enhanced many areas of science and medicine, thanks, in part, to the National Institute of Standards and Technology (NIST).
Quantum chaos in ultracold gas discovered
A team of University of Innsbruck researchers discovered that even simple systems, such as neutral atoms, can possess chaotic behavior, which can be revealed using the tools of quantum mechanics. The ground-breaking ...
The debut of the antihydrogen beam
The standard model of particle physics suggests that matter and antimatter are equal and opposite in every way. Yet the observable Universe is made almost entirely of matter—an asymmetry that remains one ...
Magnetically stimulated flow patterns offer strategy for heat transfer problems
(Phys.org) —Sandia National Laboratories researchers Jim Martin and Kyle Solis have what Martin calls "a devil of a problem."
Observed live with X-ray laser: Electricity controls magnetism
Researchers from ETH Zurich and the Paul Scherrer Institute PSI demonstrate how the magnetic structure can be altered quickly in novel materials. The effect could be used in efficient hard drives of the future.
Mystery of planet-forming disks explained by magnetism
(Phys.org) —Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006.
Colored diamonds are a superconductor's best friend
(Phys.org) —Flawed but colorful diamonds are among the most sensitive detectors of magnetic fields known today, allowing physicists to explore the minuscule magnetic fields in metals, exotic materials and ...
Scientists identify a plasma plume that naturally protects the Earth against solar storms
The Earth's magnetic field, or magnetosphere, stretches from the planet's core out into space, where it meets the solar wind, a stream of charged particles emitted by the sun. For the most part, the magnetosphere ...
How magnetic crustal fields affect planets
If you are ever lost on the surface of Mars, don't count on a compass to help you get home. On Mars, compasses don't work.
Data storage capacity is enhanced by mixing hard and soft magnetic materials
A computer hard disk uses a process called magnetic recording to store digital data. This involves applying a small field to switch the physical properties of grains of a magnetic material. The grains exist ...
Fusion, and friction, and fields! Oh, my! The rich and ubiquitous world of fluid dynamics
Scientists transfer genes required for formation of intracellular biocompass into a non-magnetic host
Magnetic bacteria navigate by means of an internal, biological compass. In a remarkable biotechnological feat, LMU scientists have succeeded in transferring the genes required for formation of the biocompass ...
The bow shock of Kappa Cassiopeiae, a massive, hot supergiant
(Phys.org) —Roguish runaway stars can have a big impact on their surroundings as they plunge through the Milky Way galaxy. Their high-speed encounters shock the galaxy, creating arcs, as seen in this newly ...
Researchers find planet-sized space weather explosions at Venus
Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called ...
