Mission to Jupiter: Gas giant may hold keys to understanding solar system formation, evolution

Posted: 01 Aug 2011 02:13 PM PDT

NASA's Juno Mission to Jupiter is slated for launch Aug. 5 from Florida's Kennedy Space Center. The primary goal of the mission is to understand the origin and evolution of the massive gas planet. The data should reveal not only the conditions of the early solar system, but also help scientists to better understand the hundreds of planetary systems recently discovered around other stars, she said.

A simple slice of energy storage

Turning graphite oxide (GO) into full-fledged supercapacitors turns out to be simple. But until a laboratory figured out how, it was anything but obvious.

Dream screens from graphene: Indium-free transparent, flexible electrodes developed

Posted: 01 Aug 2011 11:25 AM PDT

Flexible, transparent electronics are closer to reality with the creation of graphene-based electrodes. Researchers have created thin films that could revolutionize touch-screen displays, solar panels and LED lighting.

Oxygen molecules found in nearby star-forming cloud

Posted: 01 Aug 2011 09:19 AM PDT

The European Space Agency's Herschel Space Observatory has found molecules of oxygen in a nearby star-forming cloud. This is the first undisputed detection of oxygen molecules in space. It concludes a long search but also leaves questions unanswered.

A bit of boron, a pinch of palladium: One-stop shop for the Suzuki reaction

Posted: 01 Aug 2011 08:41 AM PDT

Thanks to chemists in Munich, a crucial type of intermediate in the so-called Suzuki reaction can now be synthesized using an economical "one-pot" strategy. These compounds are used on an industrial scale to make the carbon scaffolds that form the basis of useful drugs and innovative materials.

Manipulating light at will: Research could help replace electronic components with optical technology

Posted: 01 Aug 2011 07:56 AM PDT

Electrical engineers have developed a material that allows them to manipulate light in much the same way that electronics manipulate flowing electrons. The researchers say the results of their latest proof-of-concept experiments could lead to the replacement of electrical components with those based on optical technologies. Light-based devices would enable faster and more efficient transmission of information, much in the same way that replacing wires with optical fibers revolutionized the telecommunications industry.

Artificial nanoparticles influence heart rate and rhythm, study finds

Posted: 01 Aug 2011 07:56 AM PDT

Artificial nanoparticles are becoming increasingly pervasive in modern life. However, their influences on our health remain largely shrouded in mystery. Using a so-called Langendorff heart, a team of scientists in Germany has now for the first time shown that selected artificial nanoparticles have a direct effect on heart rate and heart rhythm.

Computers: The art of magnetic writing

Posted: 01 Aug 2011 07:56 AM PDT

Miniaturization in computer hard drives allows us to store vast amounts of digital data in a very small space, but it has created numerous problems that physicists and engineers are struggling to solve. The process of writing information on tiny magnetic bits one by one, as fast as possible, and with little energy consumption, represents one of the biggest hurdles in this field. Now, scientists in Europe have discovered a new method to write magnetic data that fulfills all of these requirements.

Cold electrons to aid better design of drugs and materials

Posted: 01 Aug 2011 06:51 AM PDT

A new source of very cold electrons will improve the quality and speed of nanoimaging for drug and materials development, to a trillionth of a second.

A new catalyst for ethanol made from biomass: Potential renewable path to fuel additives, rubber and solvents

Posted: 01 Aug 2011 06:51 AM PDT

Researchers have developed a new catalyst material that could replace chemicals currently derived from petroleum and be the basis for more environmentally friendly products including octane-boosting gas and fuel additives, bio-based rubber for tires and a safer solvent for the chemicals industry.

Avoiding Nemesis: Does impact rate for asteroids and comets vary periodically with time?

Posted: 01 Aug 2011 06:42 AM PDT

Is Earth more likely or less likely to be hit by an asteroid or comet now as compared to, say, 20 million years ago? Several studies have claimed to have found periodic variations, with the probability of giant impacts increasing and decreasing in a regular pattern. Now a new analysis shows those simple periodic patterns to be statistical artifacts. The results indicate either that Earth is as likely to suffer a major impact now as it was in the past, or that there has been a slight increase impact rate events over the past 250 million years.

Sugar doesn't melt -- it decomposes, scientists demonstrate

Posted: 25 Jul 2011 09:35 AM PDT

Flying in the face of years of scientific belief, researchers have demonstrated that sugar doesn't melt, it decomposes. This discovery is important to food scientists and candy lovers because it will give them yummier caramel flavors and more tantalizing textures. It even gives the pharmaceutical industry a way to improve excipients, the proverbial spoonful of sugar that helps your medicine go down.
