New explanation for star formation: Computer simulations to provide physical explanation for Larson’s Laws

Posted: 21 Oct 2013 01:27 PM PDT

Astrophysics researchers for the first time provides an explanation for the origin of three observed correlations between various properties of molecular clouds in the Milky Way galaxy known as Larson's Laws.

Atomically thin device promises new class of electronics: Tunable electrical behavior not previously realized in conventional devices

Posted: 21 Oct 2013 01:26 PM PDT

As electronics approach the atomic scale, researchers are increasingly successful at developing atomically thin, virtually two-dimensional materials that could usher in the next generation of computing. Integrating these materials to create necessary circuits, however, has remained a challenge. Researchers have now taken a significant step toward fabricating complex nanoscale electronics: the creation of a p-n heterojunction diode, a fundamental building block of modern electronics.

Nano-cone textures generate extremely 'robust' water-repellent surfaces

Posted: 21 Oct 2013 10:11 AM PDT

Scientists create surfaces with differently shaped nanoscale textures that may yield improved materials for applications in transportation, energy, and diagnostics.

Cheap metals can be used to make products from petroleum

Posted: 21 Oct 2013 10:10 AM PDT

A new process suggests that base metals may be worth more than their weight in gold -- as catalysts in the manufacture of countless products made from petroleum-based raw materials.

Rings, dark side of Saturn glow in new Cassini image

Posted: 21 Oct 2013 07:38 AM PDT

The gauzy rings of Saturn and the dark side of the planet glow in newly released infrared images obtained by NASA's Cassini spacecraft.

Topological light: Living on the edge

Posted: 21 Oct 2013 07:37 AM PDT

Scientists report the first observation of topological effects for light in two dimensions, analogous to the quantum Hall effect for electrons. To accomplish this, they built a structure to guide infrared light over the surface of a room temperature, silicon-on-insulator chip.

Managing the deluge of 'Big Data' from space

Posted: 21 Oct 2013 07:28 AM PDT

For NASA and its dozens of missions, data pour in every day like rushing rivers. Spacecraft monitor everything from our home planet to faraway galaxies, beaming back images and information to Earth. All those digital records need to be stored, indexed and processed so that spacecraft engineers, scientists and people across the globe can use the data to understand Earth and the universe beyond.

Cleaner and greener cities with integrated transparent solar cells

Posted: 21 Oct 2013 06:51 AM PDT

Imagine buildings in which the windows allow the sun's light to enter, and at the same time capture the energy from the sun needed to meet all their energy needs. In this seemingly futuristic scenario, the windows become productive solar cells that help us decrease our reliance on fossil fuels and advance towards a greener and cleaner environment. Researchers have now fabricated an optimal organic solar cell with a high level of transparency and a high power conversion efficiency, a promising step forward towards affordable, clean, more widely utilized and urban integrated renewable energies.

Nanodiamonds made under ambient conditions

Posted: 21 Oct 2013 06:50 AM PDT

Researchers have developed a way to cheaply make nanodiamonds on a lab bench at atmospheric pressure and near room temperature. The nanodiamonds are formed directly from a gas and require no surface to grow on.

Scientists untangle nanotubes to release their potential in the electronics industry

Posted: 21 Oct 2013 06:47 AM PDT

Researchers have demonstrated how to produce electronic inks for the development of new applications using the 'wonder material', carbon nanotubes.

Getting ready for Generation-C: Creative consumers who modify electronics

Posted: 21 Oct 2013 06:45 AM PDT

A generational movement consisting of creative consumers who modify proprietary offerings, and of members of society who in turn use their developments, all without any moral and legal considerations. Think video and audio mashups, jailbreaks for game consoles, unlocked mobile phones, tuned cars, even 'hacked' vacuum cleaners that can now be controlled remotely, via mobile phone apps.
