Revisiting Stokes drift: Waves of the future

Posted: 30 Sep 2014 10:25 AM PDT

The 19th-century 'Stokes drift' concept that a tiny sphere on a small wave would trace a spiral, not a closed circle, was assumed to be unlikely to occur in nature. But using 21st-century technologies, scientists found that not only do the particles move, they move predictably, and can even be planned.

A heartbeat away? Hybrid 'patch' could replace transplants

Posted: 30 Sep 2014 08:34 AM PDT

Because heart cells cannot multiply and cardiac muscles contain few stem cells, heart tissue is unable to repair itself after a heart attack. Now researchers are literally setting a new gold standard in cardiac tissue engineering, using gold particles to increase the conductivity of biomaterials.

How to make a 'perfect' solar absorber

Posted: 30 Sep 2014 08:32 AM PDT

Researchers have developed a solar cell that can tap the sun's full radiation spectrum. The material is a two-dimensional metallic dielectric photonic crystal, and has the additional benefits of absorbing sunlight from a wide range of angles and withstanding extremely high temperatures. Perhaps most importantly, the material can also be made cheaply at large scales.

New material steals oxygen from the air: One spoonful absorbs all the oxygen in a room

Posted: 30 Sep 2014 08:32 AM PDT

Researchers have synthesized crystalline materials that can bind and store oxygen in high concentrations. Just one spoon of the substance is enough to absorb all the oxygen in a room. The stored oxygen can be released again when and where it is needed.

Astronomers find 'cousin' planets around twin stars

Posted: 30 Sep 2014 06:04 AM PDT

Astronomers have found two new Jupiter-sized extra-solar planets, each orbiting one star of a binary-star system.  Most known extra-solar planets orbit stars that are alone, like our Sun. Yet many stars are part of binary systems, twin stars formed from the same gas cloud. Now, for the first time, two stars of a binary system are both found to host a "hot Jupiter'' exoplanet.

Selectively rewiring brain's circuitry to treat depression

Posted: 30 Sep 2014 06:03 AM PDT

On Star Trek, it is easy to take for granted the incredible ability of futuristic doctors to wave small devices over the heads of both humans and aliens, diagnose their problems through evaluating changes in brain activity or chemistry, and then treat behavior problems by selectively stimulating relevant brain circuits. While that day is a long way off, transcranial magnetic stimulation (TMS) of the left dorsolateral prefrontal cortex does treat symptoms of depression in humans by placing a relatively small device on a person's scalp and stimulating brain circuits.

Deceptive-looking vortex line in superfluid led to twice-mistaken identity

Posted: 30 Sep 2014 06:01 AM PDT

Researchers have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence of solitons -- exotic, solitary waves. Instead, they explain, the result was due to more pedestrian, whirlpool-like structures in the fluid. Mysterious effect found in superfluids were pedestrian whirlpool-like structures, not exotic solitons.
