UN chief says current climate pledges insufficient

November 19, 2013 1:57 pm | by KARL RITTER, Associated Press | News | Comments

U.N. Secretary-General Ban Ki-moon on Tuesday urged governments to put forth more ambitious plans to cut carbon emissions, saying "current pledges are simply inadequate." Speaking to a U.N. climate conference in Warsaw, Ban said countries need to "set the bar higher" as they negotiate a new global climate agreement that is supposed to be adopted in Paris in 2015.

Disney Research algorithms improve animations featuring fog, smoke and underwater scenes

November 19, 2013 1:43 pm | by EurekAlert! | News | Comments

A team led by Disney Research, Zürich has developed a method to more efficiently render animated scenes that involve fog, smoke or other substances that affect the travel of light, significantly reducing the time necessary to produce high-quality images or animations without grain or noise.

UNH scientists document, quantify deep-space radiation hazards

November 19, 2013 1:36 pm | by EurekAlert! | News | Comments

Scientists from the University of New Hampshire and colleagues have published comprehensive findings on space-based radiation as measured by a UNH-led detector aboard NASA's Lunar Reconnaissance Orbiter (LRO). The data provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars.

Photos of the Day: UT Dallas computer scientists create 3-D technique

November 19, 2013 12:30 pm | by University of Texas at Dallas | News | Comments

UT Dallas computer scientists have developed a technique to make 3-D images that finds practical applications of a theory created by a famous mathematician. This technique uses anisotropic triangles to create 3-D “mesh” computer graphics that more accurately approximate the shapes of the original objects...

Customized power distribution increases productivity and safety in electronic product development

November 19, 2013 12:30 pm | by Greg Willits, Software Development, Marway Power Solutions | Articles | Comments

Electronics equipment development generally includes one or more of design verification testing, reliability testing, and product characterization where hardware behavior is studied and documented. Design verification testing (DVT) in electrical and electronic systems is the process whereby the behavior of circuits is examined step-by-step....

Like other offenses, cyberdeviance and cybercrime seem to start and peak in the teen years

November 19, 2013 12:10 pm | by EurekAlert! | News | Comments

Tech-y teens, often more curious than criminal, are likely to start turning their talents to cyberdeviance and cybercrime at about age 15, with such activities peaking at about age 18. That's according to a snapshot survey by University of Cincinnati researchers....

SlipChip counts molecules with chemistry and a cell phone

November 19, 2013 12:07 pm | by California Institute of Technology | News | Comments

In developing nations, rural areas, and even one's own home, limited access to expensive equipment and trained medical professionals can impede the diagnosis and treatment of disease. Many qualitative tests that provide a simple "yes" or "no" answer (like an at-home pregnancy test) have been optimized for use in these resource-limited settings.

Optimizing electronic correlations for superconductivity

November 19, 2013 12:07 pm | by EurekAlert! | News | Comments

The decades-long effort to create practical superconductors moved a step forward with the discovery at Rice University that two distinctly different iron-based compounds share common mechanisms for moving electrons. Samples from two classes of iron-based superconductors, pnictides and chalcogenides, employ similar coupling....

Chaotic physics in ferroelectrics hints at brain-like computing

November 19, 2013 12:04 pm | by EurekAlert! | News | Comments

Unexpected behavior in ferroelectric materials explored by researchers at the Department of Energy's Oak Ridge National Laboratory supports a new approach to information storage and processing. Ferroelectric materials are known for their ability to spontaneously switch polarization when an electric field is applied.
