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.
Surprises in the South polar vortex in Venus' atmosphere
Spanish astronomers with the UPV/EHU's Planetary Science Group have published, online in the journal Nature Geoscience, a study of the atmospheric vortex of the south pole of Venus, a huge whirlwind the si ...
Study shows hovering hummingbirds generate two trails of vortices under their wings, challenging one-vortex consensus
As of today, the Wikipedia entry for the hummingbird explains that the bird's flight generates in its wake a single trail of vortices that helps the bird hover. But after conducting experiments with hummi ...
Aviation industry dons 'shark skins' to save fuel
In its never-ending quest to develop more aerodynamic, more fuel-efficient aircraft, the aviation industry believes the ocean's oldest predator, the shark, could hold the key to cutting energy consumption.
Vortex pinning could lead to superconducting breakthroughs
A team of researchers from Russia, Spain, Belgium, the U.K. and the U.S. Department of Energy's (DOE) Argonne National Laboratory announced findings last week that may represent a breakthrough in applications ...
Engineer looks to dragonflies, bats for flight lessons
(Phys.org)—Ever since the Wright brothers, engineers have been working to develop bigger and better flying machines that maximize lift while minimizing drag.
Magnetic bubbles behave differently than other magnetic defects (w/ video)
Beautiful physics: Tying knots in light
New research published today seeks to push the discovery that light can be tied in knots to the next level.
Earth's magnetosphere behaves like a sieve
ESA's quartet of satellites studying Earth's magnetosphere, Cluster, has discovered that our protective magnetic bubble lets the solar wind in under a wider range of conditions than previously believed.
Symmetry breaking during flapping generates lift
Vortices in atomic gases resolve basic phenomena of quantum physics
Quantum phenomena at extremely low temperatures are fervently studied both theoretically and experimentally in contemporary physics. Alkali atoms cooled to near absolute zero formed the first experimentally successful gaseous ...
Going with the flow
Scientists who study tissue engineering and test new drugs often need to sort, rotate, move, and otherwise manipulate individual cells. They can do this by prodding the cells into place with a mechanical probe or coaxing ...
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 ...
