Health policy researchers lack confidence in social media for communicating scientific evidence Posted: 06 Jun 2014 10:54 AM PDT 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. In contrast, sixty-five percent used traditional media channels, such as press releases or media interviews. While participants believed that social media can be an effective way to communicate research findings, many lacked the confidence to use it and felt their academic peers and institutions did not value it or respect it as much as traditional media and direct contact with policy makers.

Evolution of a bimetallic nanocatalyst Posted: 06 Jun 2014 10:14 AM PDT 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.

Opening a wide window on the nano-world of surface catalysis Posted: 06 Jun 2014 07:20 AM PDT A surface catalyst with a built-in sensor: that's what chemists built by bridging a size gap on the nano-scale. Their silver nanoparticles combine plasmon resonance with catalytic activity, making SERS and other analytical data available in real time on a surface catalyst.

Shatterproof screens that save smartphones Posted: 06 Jun 2014 07:20 AM PDT Researchers have demonstrated how a transparent layer of electrodes on a polymer surface could be extraordinarily tough and flexible, withstanding repeated Scotch tape peeling and bending tests.

Method of synthesizing new type of nickel-carbon heterofullerenes Posted: 06 Jun 2014 07:20 AM PDT Scientists have come up with a method of synthesizing a new type of nickel-carbon compound. Heterofullerenes are hollow molecules with a nearly-spherical shape, which, unlike the typical fullerenes, contain atoms of elements other than carbon. Such compounds were synthesized quite a while ago, in 1991, but till now no heterofullerenes containing nickel, or any other transition metal, have been obtained.

Magnetic moment of the proton measured with unprecedented precision Posted: 06 Jun 2014 07:19 AM PDT Physicists succeeded in the first direct high-precision measurement of a fundamental property of the proton. Results will contribute to a better understanding of the matter/antimatter asymmetry.

Drastic cut in electricity bill for supermarket in Norway Posted: 06 Jun 2014 06:15 AM PDT A newly built mini-supermarket was opened last autumn in Norway by a government minister to the sound of a brass band. Throughout the winter, it used 30 per cent less electricity than four comparable stores in the capital of mid-Norway, where of course the outdoor temperature was the same for all of them.

New diagnostic imaging techniques deemed safe in simulations Posted: 04 Jun 2014 10:37 AM PDT Gamma and neutron imaging offer possible improvements over existing techniques such as X-ray or CT, but their safety is not yet fully understood. Using computer simulations, imaging the liver and breast with gamma or neutron radiation was found to be safe, delivering levels of radiation on par with conventional medical imaging, according to researchers.

Count of new CFCs in the atmosphere rises from four to seven Posted: 03 Jun 2014 04:39 PM PDT Two new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been found in the atmosphere by a group of scientists. Scientists made the discovery by comparing today's air samples with air collected between 1978 and 2012 in unpolluted Tasmania, and samples taken during aircraft flights. Measurements show that all but one of the new gases have been released into the atmosphere in recent years.
