How water dissolves stone, molecule by molecule

Posted: 05 Dec 2013 03:56 PM PST

Scientists have combined cutting-edge experimental techniques and computer simulations to find a new way of predicting how water dissolves crystalline structures like those found in natural stone and cement.

NASA Goddard planetary instruments score a hat trick

Posted: 05 Dec 2013 03:56 PM PST

Planetary instruments from NASA's Goddard Space Flight Center in Greenbelt, Md., hit the trifecta on Dec. 4, running three experiments of the same kind at different places in space.

Researchers create nonlinear light-generating zero-index metamaterial

Posted: 05 Dec 2013 02:17 PM PST

Researchers have used a unique optical metamaterial with zero-index refraction to generate phase mismatch–free nonlinear light, an important step towards efficient light generation for future quantum networks and light sources.

'Spinning trap' developed to measure electron roundness

Posted: 05 Dec 2013 02:17 PM PST

Researchers have developed a method of spinning electric and magnetic fields around trapped molecular ions to measure whether the ions' tiny electrons are truly round -- research with major implications for future scientific understanding of the universe.

You can't get entangled without a wormhole: Physicist finds entanglement instantly gives rise to a wormhole

Posted: 05 Dec 2013 11:22 AM PST

Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics -- so strange, in fact, that Albert Einstein famously referred to it as "spooky action at a distance."

Astronomers discover planet that shouldn't be there

Posted: 05 Dec 2013 11:16 AM PST

Astronomers have discovered the most distantly orbiting planet found to date around a single, sun-like star. Weighing in at 11 times Jupiter's mass and orbiting its star at 650 times the average Earth-Sun distance, planet HD 106906 b is unlike anything in our own Solar System and defies current planet formation theories.

Laser light at useful wavelengths from semiconductor nanowires

Posted: 05 Dec 2013 06:29 AM PST

Thread-like semiconductor structures called nanowires, so thin that they are effectively one-dimensional, show potential as lasers for applications in computing, communications, and sensing. Scientists have demonstrated laser action in semiconductor nanowires that emit light at technologically useful wavelengths and operate at room temperature. They now have documented this breakthrough and have disclosed further results showing enhanced optical and electronic performance.

Soft mini-robots: Micro-robots will become soft and move like biological organisms, experts predict

Posted: 05 Dec 2013 06:20 AM PST

Increasingly small robots can carry out their functions even inside the human body. No, this isn't a sci-fi dream. The technology is almost ready. However there is still one condition they must meet to be effective: these devices need to have the same "softness" and flexibility as biological tissues.

Telemedicine brings Parkinson's care to 'anyone, anywhere'

Posted: 04 Dec 2013 03:18 PM PST

A new study shows that a neurologist in an office thousands of miles away can deliver effective specialized care to people with Parkinson's disease. For individuals with the condition -- many of whom have never seen a specialist -- these "virtual house calls" could allow them to live independently while effectively manage the symptoms of the disease.

Tune in, turn on, power up

Posted: 04 Dec 2013 03:12 PM PST

Human beings don't come with power sockets, but a growing numbers of us have medical implants that run off electricity. To keep our bionic body parts from powering down, a group of researchers is developing a safe, noninvasive, and efficient means of wireless power transmission through body tissue.

Swallowing a diagnostic pill

Posted: 04 Dec 2013 07:38 AM PST

A tiny capsule that can carry out a chemical analysis of the contents of one's stomach could identify the presence of so-called "occult" blood at very low levels. The data is automatically broadcast to an external monitoring device for detection of early stage stomach cancer by one's physician.

Ultrathin 'diagnostic skin' allows continuous patient monitoring

Posted: 04 Dec 2013 07:36 AM PST

A multidisciplinary research team has developed an ultrathin membrane that can stick to skin and carry arrays of diagnostic sensors and stimulatory components. The "electronic skin" allows remote patient monitoring and may someday be used to deliver treatments.
