Neutrons and X-rays reveal structure of high-temperature liquid metal oxides

June 10, 2014 8:13 am | by Argonne National Laboratory | News | Comments

By levitating a bead of ceramic oxide, heating it with a 400-watt carbon dioxide laser, then shooting the molten material with X-rays and neutrons, scientists with the Department of Energy’s Oak Ridge and Argonne national laboratories have revealed unprecedented detail of the structure....

Method of nickel-carbon heterofullerenes synthesis presented

June 9, 2014 3:18 pm | by EurekAlert! | News | Comments

Scientists from several British, Spanish and Russian research centers (MIPT, Institute for Spectroscopy RAS, Kurchatov Institute and Kintech Lab Ltd) have come up with a method of synthesizing a new type of nickel-carbon compound. The article titled Formation of nickel-carbon heterofullerenes under electron irradiation ...

Opening a wide window on the nano-world of surface catalysis

June 9, 2014 3:15 pm | by EurekAlert! | News | Comments

Surface catalysts are notoriously difficult to study mechanistically, but scientists at the University of South Carolina and Rice University have shown how to get real-time reaction information from Ag nanocatalysts that have long frustrated attempts to describe their kinetic behavior in detail....

Exotic particle confirmed

June 9, 2014 3:12 pm | by EurekAlert! | News | Comments

For decades, physicists have searched in vain for exotic bound states comprising more than three quarks. Experiments performed at Jülich's accelerator COSY have now shown that, in fact, such complex particles do exist in nature. This discovery by the WASA-at-COSY collaboration has been published in the journal Physical Review Letters....

Magnetic moment of the proton measured with unprecedented precision

June 9, 2014 3:09 pm | by EurekAlert! | News | Comments

One of the biggest riddles in physics is the apparent imbalance between matter and antimatter in our universe. To date, there is no explanation as to why matter and antimatter failed to completely annihilate one another immediately after the big bang....

Evolution of a bimetallic nanocatalyst

June 9, 2014 3:05 pm | by EurekAlert! | News | Comments

Atomic-scale snapshots of a bimetallic nanoparticle catalyst in action have provided insights that could help improve the industrial process by which fuels and chemicals are synthesized from natural gas, coal or plant biomass. A multi-national lab collaboration led by researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory....

Nanoparticle thin films that self-assemble in one minute

June 9, 2014 3:02 pm | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have devised a technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film....

Study shows health policy researchers lack confidence in social media for communication

June 9, 2014 2:59 pm | by EurekAlert! | News | Comments

Though Twitter boats 645 million users across the world, only 14 percent of health policy researchers reported using Twitter – and approximately 20 percent used blogs and Facebook – to communicate their research findings over the past year, according to a new study from the Perelman School of Medicine at the University of Pennsylvania....

Study reveals rats show regret, a cognitive behavior once thought to be uniquely human

June 9, 2014 2:58 pm | by EurekAlert! | News | Comments

New research from the Department of Neuroscience at the University of Minnesota reveals that rats show regret, a cognitive behavior once thought to be uniquely and fundamentally human. Research findings were recently published in Nature Neuroscience....

Targeting tumors using silver nanoparticles

June 9, 2014 2:54 pm | by EurekAlert! | News | Comments

Scientists at UC Santa Barbara have designed a nanoparticle that has a couple of unique — and important — properties. Spherical in shape and silver in composition, it is encased in a shell coated with a peptide that enables it to target tumor cells. What's more, the shell is etchable....

More than just a hill of beans: Phaseolus genome lends insights into nitrogen fixation

June 9, 2014 2:48 pm | by EurekAlert! | News | Comments

"It doesn't take much to see that the problems of three little people doesn't add up to a hill of beans in this crazy world," Humphrey Bogart famously said in the movie Casablanca. For the farmers and breeders around the world growing the common bean, however, ensuring that there is an abundant supply of this legume is crucial....

The Past and Future of Electroncis

June 9, 2014 2:46 pm | by Screaming Circuits | Blogs | Comments

Our parent company, Milwaukee Electronics was founded 60 years ago, in 1954. That's quite a long time in terms of electronics. 60 years back 1954 was a big year for transistor electronics. The first commercially produced transistor radio, the Regency...

Angry faces back up verbal threats, making them seem more credible

June 9, 2014 10:49 am | by EurekAlert! | News | Comments

We've all been on the receiving end of an angry glare, whether from a teacher, parent, boss, or significant other. These angry expressions seem to boost the effectiveness of threats without actual aggression, according to research published in Psychological Science, a journal of the Association for Psychological Science....

This is what the terminator line looks like from the ISS

June 9, 2014 10:27 am | by Kasey Panetta, Managing Editor | Blogs | Comments

NASA has been very into social media lately, and I could not be more excited. It’s a great way to inspire younger generations and remind everyone why the space program—despite its not insignificant costs—is so important. NASA has been capitalizing on the “space is cool again” trend...

Free speech or illegal threats? Justices could say

June 9, 2014 10:19 am | by SAM HANANEL, Associated Press | News | Comments

Messages posted on Facebook and Twitter or sent in emails can be tasteless, vulgar and even disturbing. But just when do they cross the line from free speech to threats that can be punished as a crime? As the Internet and social networks allow people to vent their frustrations with the click of a mouse ...
