New framework for understanding the energetics of ionic liquids

Posted: 07 Jun 2013 01:03 PM PDT

A new study provides clues into the understanding of the behavior of the charged molecules or particles in ionic liquids. The new framework may lead to the creation of cleaner, more sustainable, and nontoxic batteries, and other sources of chemical power.

A Hubble view of NGC 1579: The Trifid of the North

Posted: 07 Jun 2013 12:36 PM PDT

Unlike the venomous fictional plants that share its name, the Trifid of the North, otherwise known as the Northern Trifid or NGC 1579, poses no threat to your vision. The nebula's moniker is inspired by the better-known Messier 20, the Trifid Nebula, which lies very much further south in the sky and displays strikingly similar swirling clouds of gas and dust.

Radar movies highlight asteroid 1998 QE2 and its moon

Posted: 07 Jun 2013 12:30 PM PDT

Scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif., have released a second, longer, more refined movie clip of asteroid 1998 QE2 and its moon. The 55 individual images used in the movie were generated from data collected at Goldstone on June 1, 2013.

Making sense of patterns in the Twitterverse

Posted: 07 Jun 2013 10:10 AM PDT

If you think keeping up with what's happening via Twitter, Facebook and other social media is like drinking from a fire hose, multiply that by seven billion -- and you'll have a sense of what Court Corley wakes up to every morning. Corley has created a powerful digital system, dubbed SALSA, capable of analyzing billions of tweets and other messages in just seconds, in an effort to discover patterns and make sense of all the information.

How do immune cells detect infections?

Researchers are using computer simulations to shed light on how immune cells may identify foreign antigens.

Whispering light hears liquids talk

Posted: 07 Jun 2013 05:53 AM PDT

Researchers have developed optomechanical sensors in which extremely minute forces exerted by light are used to generate and control high-frequency mechanical vibrations of microscale and nanoscale devices that will help unlock vibrational secrets of chemical and biological samples at the nanoscale.

'Long-awaited explanation' for mysterious effects in high-temperature superconductors

Posted: 07 Jun 2013 05:53 AM PDT

A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. The calculations predict two coexisting electron orders. Below a certain temperature, superconductors lose their electrical resistance and can conduct electricity without loss.

Better screens made of organic light diodes: OLED brings out the shine

Posted: 07 Jun 2013 05:52 AM PDT

Screens made of organic light diodes promise unfathomable possibilities. Yet high production costs often prevent their widespread use. A new kind of production saves not only costs, but also improves the radiance of the OLED.

Glove shows its true colors: Identifies poisons on contact

Posted: 07 Jun 2013 05:52 AM PDT

Security takes top priority in laboratories and in production. In the future, employees exposed to risks will only have to put on a glove in order to receive a toxic substance warning: This textile identifies poisonous substances, and points them out immediately.

2011 Draconid meteor shower deposited a ton of meteoritic material on Earth

Posted: 06 Jun 2013 11:10 AM PDT

About a ton of material coming from comet 21P/Giacobini-Zinner was deposited in the Earth's atmosphere on October 8th and 9th, 2011 during one of the most intense showers of shooting starts in the last decade, which registered an activity of more than 400 meteors per hour.
