Scientists create 'building block' of quantum networks

Posted: 07 Feb 2013 04:21 PM PST

A proof-of-concept device that could pave the way for on-chip optical quantum networks has been created by a group of researchers. The device has been described as the "building block of future quantum networks."

Holographic microscopy: Peering into living cells -- with neither dye nor fluophore

Posted: 07 Feb 2013 02:22 PM PST

Thanks to holographic microscopy, two young scientists have developed a device that can create 3-D images of living cells, almost in real time, and track their reaction to various stimuli without the use of contrast dyes or fluorophores.

New classes of magnetoelectric materials promise advances in computing technology

Posted: 07 Feb 2013 02:21 PM PST

Physicists have developed new methods for controlling magnetic order in a particular class of materials known as "magnetoelectrics."

Nanoscopic microcavities offer newfound control in light filtering: Unique nanostructure produces novel 'plasmonic halos'

Posted: 07 Feb 2013 12:09 PM PST

Researchers report developing a unique nanostructure capable of filtering visible light into "plasmonic halos" of desired color output.

Scientists solve mercury mystery, taking big step toward protecting human health

Posted: 07 Feb 2013 11:14 AM PST

By identifying two genes required for transforming inorganic into organic mercury, which is far more toxic, scientists have just taken a significant step toward protecting human health.

Solving big-data bottleneck: Scientists team with business innovators to tackle research hurdles

Posted: 07 Feb 2013 11:14 AM PST

Researchers have demonstrated that a crowdsourcing platform pioneered in the commercial sector can solve a complex biological problem more quickly than conventional approaches -- and at a fraction of the cost.

Fluorescent label sheds light on radioactive contamination

Posted: 07 Feb 2013 11:12 AM PST

Researchers have developed a way to detect caesium contamination on a scale of millimeters enabling the detection of small areas of radioactive contamination.

NASA telescopes discover strobe-like flashes in young stars

Posted: 07 Feb 2013 10:29 AM PST

Two of NASA's great observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a strobe light. Every 25.34 days, the object, designated LRLL 54361, unleashes a burst of light. Although a similar phenomenon has been observed in two other young stellar objects, this is the most powerful such beacon seen to date. The heart of the fireworks is hidden behind a dense disk and an envelope of dust. Astronomers propose the light flashes are caused by periodic interactions between two newly formed stars that are binary, or gravitationally bound to each other.

NASA scientists build first-ever wide-field X-ray imager

Posted: 07 Feb 2013 10:17 AM PST

Three NASA scientists teamed up to develop and demonstrate NASA's first wide-field-of-view soft X-ray camera for studying "charge exchange," a poorly understood phenomenon that occurs when the solar wind collides with Earth's exosphere and neutral gas in interplanetary space.

Scientists discover how the world's saltiest pond gets its salt

Posted: 07 Feb 2013 10:17 AM PST

Antarctica's Don Juan Pond exists only because its high salinity -- the highest of any body of water on the planet -- keeps it from freezing. New researcher finds that water sucked out of the air by parched, salty soil provides the saltwater brine that enables the pond to persist in one of the coldest and driest places on Earth. The findings could shed light on possibility of flowing water on Mars.

'Zombie' cells may outperform live ones as catalysts and conductors

Posted: 07 Feb 2013 08:46 AM PST

A simple technique uses silica to coat a living cell both inside and outside. The process forms a near-perfect replica of the cell's structure, down to the tiniest organelle. The resulting model, heated, creates nature-sculpted nanotools with components far stronger than when built out of flesh.

High-energy X-rays shine light on mystery of Picasso's paints

Posted: 07 Feb 2013 06:31 AM PST

Scientists have unraveled a decades-long debate among art scholars about what kind of paint Picasso used to create his masterpieces.
