Engineers' new metamaterial doubles up on invisibility (w/ Video)
(Phys.org) —The new material's artificial "atoms" are designed to work with a broad range of light frequencies. With adjustments, the researchers believe it could lead to perfect microscope lenses or invisibility ...
Looking at quantum gravity in a mirror
Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale ...
Astronomers solve mystery of vanishing energetic electrons in Earth's outer radiation belt
UCLA researchers have explained the puzzling disappearing act of energetic electrons in Earth's outer radiation belt, using data collected from a fleet of orbiting spacecraft.
Testing relativity in the lab
Even Albert Einstein might have been impressed. His theory of general relativity, which describes how the gravity of a massive object, such as a star, can curve space and time, has been successfully used to ...
Now you see it, now you don't: Scientists unraveling the mystery of camouflage
At Hogwarts, Harry Potter uses an invisibility cloak to hide from his enemies. In nature, animals like cuttlefish and chameleons use the awe-inspiring tricks of camouflage to hide from theirs.
US court case could mean doom for software patents (Update)
The U.S. Supreme Court decided Friday to hear an appeal of a lower court decision that a federal judge called the "death" of software patents.
Penetrating the quantum nature of magnetism
Antiferromagnets are materials that lose their apparent magnetic properties when cooled down close to absolute zero temperature. Different to conventional magnets, which can be described with classical physics ...
Competition in the quantum world
Innsbruck physicists led by Rainer Blatt and Peter Zoller experimentally gained a deep insight into the nature of quantum mechanical phase transitions. They are the first scientists that simulated the competition ...
Game group gets word on Intel's new extensions for rendering
Scientists observe coherent propagation of single spin impurity in a chain of ultracold atoms
Many discoveries in physics came as a big surprise – for example the phenomenon, that some materials loose almost all their electrical resistance at low temperatures, or that others become superconductors ...
3D-Model mimics volcanic explosions
(PhysOrg.com) -- A 3-D model of a volcanic explosion, based on the 1980 eruption of Mount St. Helens in Washington state, may enhance our understanding of how some volcanic explosions occur and help identify ...
Quantum simulation with light: Frustrations between photon pairs
Researchers of the University of Vienna used a quantum mechanical system in the laboratory to simulate complex many-body systems. This experiment promises future quantum simulators enormous potential insights ...
New spacecraft could help break the climate debate gridlock
A new robotic probe is headed to the launch pad, aiming for a spot aboard what is called the A-train -- a fleet of Earth-orbiting spacecraft keeping tabs on the planet's changing climate.
Tempest in a teapot: Scientists describe swirling natural phenomena
(Santa Barbara, Calif.) Scientists can use cylinders as small as teapots to study the mechanisms involved in powerful hurricanes and other swirling natural phenomena.
