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.
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.
Computer simulation shows the sun's "heartbeat" is magnetic
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 ...
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 ...

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.
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.
