Saturn's largest moon Titan gets a dune 'makeover'

Posted: 17 Jan 2013 03:34 PM PST

Titan's siblings must be jealous. While most of Saturn's moons display their ancient faces pockmarked by thousands of craters, Titan -- Saturn's largest moon -- may look much younger than it really is because its craters are getting erased. Dunes of exotic, hydrocarbon sand are slowly but steadily filling in its craters, according to new research using observations from NASA's Cassini spacecraft.

Researchers have recently demonstrated the most complex 2-D optical phased array ever.

Doubling down on energy efficiency

Posted: 17 Jan 2013 11:25 AM PST

Spending on energy efficiency programs funded by electric and natural gas utility customers will double by 2025 to about $9.5 billion per year, according to new projections. According to the report, energy efficiency programs funded by utility customers are projected to continue expanding beyond the traditional bastions of energy efficiency in the Northeast and West.

Novel sensor provides bigger picture: Efficient, flexible, versatile and cheap

Posted: 17 Jan 2013 11:25 AM PST

Engineers have developed a novel sensor that is more efficient, versatile and cheaper for potential use in such applications as airport security scanners and collision avoidance systems for aircraft, cars or maritime vessels. The material is flexible and durable enough to be attached to a wall, wrapped around corners or even laid on the floor like a rug, making it an inexpensive alternative for a variety of sensing applications.

Microscopes for inside magnetic materials using Barkhausen Effect

Posted: 17 Jan 2013 11:25 AM PST

Almost 100 years after the initial discovery, a team of scientists have harnessed the Barkhausen Effect as a new kind of high-resolution microscopy for the insides of magnetic materials.

Separating gases using a rigid polymer sieve: New polymer selectively sieves gas molecules

Posted: 17 Jan 2013 11:25 AM PST

A new polymer may lead to more efficient large-scale separation of gas mixtures for chemical engineering and energy generation.

Method for more sensitive electrochemical sensors

Posted: 17 Jan 2013 10:32 AM PST

Scientists have recently developed a new method for amplifying signals in graphene-based electrochemical sensors, a step that could make the sensors more sensitive at lower detection ranges.

Cheating to create the perfect simulation: Physicists on way to describing inside of neutron stars

Posted: 17 Jan 2013 10:32 AM PST

Scientists have succeeded in simulating the strong atomic nuclear interactions to enable its calculability while at the same time preserving the typical characteristics of a neutron star.

Hidden treasure in Large Magellanic Cloud

Posted: 17 Jan 2013 07:58 AM PST

Nearly 200,000 light-years from Earth, the Large Magellanic Cloud, a satellite galaxy of the Milky Way, floats in space, in a long and slow dance around our galaxy. Vast clouds of gas within it slowly collapse to form new stars. In turn, these light up the gas clouds in a riot of colors, visible in this image from the NASA/ESA Hubble Space Telescope.
