NASA's WISE survey finds thousands of new stars, but no 'Planet X'

Posted: 07 Mar 2014 01:06 PM PST

After searching hundreds of millions of objects across our sky, NASA's Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed "Planet X."

Promising news for producing fuels through artificial photosynthesis

Posted: 07 Mar 2014 10:36 AM PST

There's promising news from the front on efforts to produce fuels through artificial photosynthesis. A new study shows that nearly 90 percent of the electrons generated by a hybrid material designed to store solar energy in hydrogen are being stored in the target hydrogen molecules.

Cassini nears 100th Titan flyby with a look back

Posted: 05 Mar 2014 08:11 AM PST

Ten years ago, we knew Titan as a fuzzy orange ball about the size of Mercury. We knew it had a nitrogen atmosphere -- the only known world with a thick nitrogen atmosphere besides Earth. But what might lie beneath the hazy air was still just a guess.

Mystery of planet-forming disks explained by magnetism

Posted: 07 Mar 2014 09:46 AM PST

Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006. Researchers using NASA's Spitzer Space Telescope to study developing stars have had a hard time figuring out why the stars give off more infrared light than expected. The planet-forming disks that circle the young stars are heated by starlight and glow with infrared light, but Spitzer detected additional infrared light coming from an unknown source.

Volume of notifiable disease reporting may double with required electronic lab reporting

Posted: 07 Mar 2014 08:11 AM PST

Public health departments nationwide are already feeling the strain from budget cuts. But their case report volumes are forecasted to double when federal requirements for automated electronic laboratory reporting of notifiable diseases go into effect next year, according to a new study.

Smartphones become 'eye-phones' with low-cost devices

Posted: 07 Mar 2014 08:10 AM PST

Researchers have developed two inexpensive adapters that enable a smartphone to capture high-quality images of the front and back of the eye. The adapters make it easy for anyone with minimal training to take a picture of the eye and share it securely with other health practitioners or store it in the patient's electronic record.

Magnetically stimulated flow patterns offer strategy for heat transfer problems

Posted: 07 Mar 2014 08:10 AM PST

Researchers have discovered how to harness magnetic fields to create vigorous, organized fluid flows in particle suspensions.

UV light accelerates cancer cells that creep along outside of blood vessels

Posted: 07 Mar 2014 07:00 AM PST

Deadly skin cancer (melanoma) cells spread by creeping along the outside of blood vessels: extravascular metastatic migration (EVMM). Ultraviolet light exposure accelerates EVMM in a mouse model, new research has found. Now researchers are targeting new drugs that slow or stop EVMM, potentially reducing the death rate from melanoma.

Software analyzes apps for malicious behavior

Posted: 07 Mar 2014 05:40 AM PST

Apps on web-enabled mobile devices can be used to spy on their users. Computer scientists have developed software that shows whether an app has accessed private data. To accomplish this, the program examines the "bytecode" of the app in question.

Interactive simulator for vehicle drivers

Posted: 07 Mar 2014 05:38 AM PST

Maximize mileage, safety, or operating life? Driving behavior behind the wheel has a big influence on the vehicle. Researchers have developed a driving simulator designed to make the 'human factor' more calculable for vehicle engineers.

Effective thermal insulation with wood foam

Posted: 07 Mar 2014 05:38 AM PST

Insulation materials of tomorrow must be both efficient and environmentally friendly. Scientists are developing insulation foam made from wood that could re- place petrochemical plastics in the long term.

Public could virtually 'travel' to space for $90 through new project

Posted: 07 Mar 2014 05:38 AM PST

Researchers have launched a unique campaign that will enable the public to 'travel' to space for the cost of a pair of trainers. Virtual Ride to Space will use cutting-edge virtual technology and a specially designed spacecraft to deliver a three-dimensional, immersive experience, allowing everyone to see what astronauts experience on an ascent to space.

Squeezing light into metals: Engineers control conductivity with inkjet printer

Posted: 07 Mar 2014 05:37 AM PST

Using an inexpensive inkjet printer, electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast components in electronic devices, make wireless technology faster or print magnetic materials.
