Magnetic bubbles behave differently than other magnetic defects (w/ video)
Symmetry breaking during flapping generates lift
Hunt for an 'unidentified electron object'
New research sheds light on the nature of 'unidentified electron objects'—a mysterious class of objects that exists in superfluid helium at low temperature.
Whirlpools on the nanoscale could multiply magnetic memory
Research at Lawrence Berkeley National Laboratory's Advanced Light Source promises four-bit magnetic cells instead of the two-bit magnetic domains of standard magnetic memories. Magnetic vortices are whirlpools ...
New phenomenon in nanodisk magnetic vortices
(Phys.org) -- The phenomenon in ferromagnetic nanodisks of magnetic vortices hurricanes of magnetism only a few atoms across has generated intense interest in the high-tech community because ...
Tying light in knots
(PhysOrg.com) -- The remarkable feat of tying light in knots has been achieved by a team of physicists working at the universities of Bristol, Glasgow and Southampton, UK, reports a paper in Nature Physics this w ...
Scientists discover rigid structure in centre of turbulence
Pioneering mathematical engineers have discovered for the first time a rigid structure which exists within the centre of turbulence, leading to hope that its chaotic movement could be controlled in the future.
Landmark experiment on wave interference from the early 1800s is revisited using gold nanoparticles
In the eighteenth century, scientists faced a conundrum: is light a wave or a particle? One of strongest pieces of evidence to support the 'wave view'—the landmark double-slit experiment—was reported ...
Phytoplankton use turbulence for travel to social gatherings
Tiny ocean plants, or phytoplankton, were long thought to be passive drifters in the sea—unable to defy even the weakest currents, or travel by their own volition. In recent decades, research has shown ...
Research promises breakthrough in internet bandwidth (w/ Video)
As rapidly increasing demand for bandwidth strains the Internet's capacity, a team of engineers has devised a new fiber optic technology that promises to increase bandwidth dramatically. The new technology could enable Internet ...
Magnetic vortex antennas for wireless data transmission
Three-dimensional magnetic vortices were discovered by scientists from the Helmholtz-Zentrum Dresden-Rossendorf together with colleagues from the Paul Scherrer Institute within the scope of an international ...
Computer simulation shows the sun's "heartbeat" is magnetic
Sonic lasso catches cells
(Phys.org) —Academics have demonstrated for the first time that a "sonic lasso" can be used to grip microscopic objects, such as cells, and move them about.
Mathematical butterflies provide insight into how insects fly
Researchers have developed sophisticated numerical simulations of a butterfly's forward flight.
