Mandatory arrest in domestic violence call-outs causes early death in victims Posted: 02 Mar 2014 04:54 PM PST Researchers followed up on a landmark domestic violence arrest experiment and found that African-American victims who had partners arrested rather than warned were twice as likely to die young.

Talking Neanderthals challenge the origins of speech Posted: 02 Mar 2014 03:52 PM PST We humans like to think of ourselves as unique for many reasons, not least of which being our ability to communicate with words. But ground-breaking research shows that our 'misunderstood cousins,' the Neanderthals, may well have spoken in languages not dissimilar to the ones we use today.

Newly discovered catalyst could lead to the low-cost production of clean methanol from carbon dioxide Posted: 02 Mar 2014 11:36 AM PST Scientists have discovered a potentially clean, low-cost way to convert carbon dioxide into methanol, a key ingredient in the production of plastics, adhesives and solvents, and a promising fuel for transportation. Scientists combined theory and experimentation to identify a new nickel-gallium catalyst that converts hydrogen and carbon dioxide into methanol with fewer side-products than the conventional catalyst.

Optical nano-tweezers control nano-objects: Trap and move individual nano-object in three dimensions using only light Posted: 02 Mar 2014 11:36 AM PST Researchers have invented nano-optical tweezers capable of trapping and moving an individual nano-object in three dimensions using only the force of light. Using this approach, they have demonstrated trapping and 3-D displacement of specimens as small as a few tens of nanometers using an extremely small, non-invasive laser intensity.

European flood risk could double by 2050 Posted: 02 Mar 2014 11:36 AM PST Losses from extreme floods in Europe could more than double by 2050, because of climate change and socioeconomic development. Understanding the risk posed by large-scale floods is of growing importance and will be key for managing climate adaptation.

Global warming felt to deepest reaches of ocean Posted: 02 Mar 2014 11:35 AM PST A new study shows that the 1970s polynya within the Antarctic sea ice pack of the Weddell Sea may have been the last gasp of what was previously a more common feature of the Southern Ocean, and which is now suppressed due to the effects of climate change on ocean salinity.

As one food allergy resolves, another may develop: Same food may trigger both allergies Posted: 02 Mar 2014 11:35 AM PST Some children who outgrow one type of food allergy may then develop another type of allergy, more severe and more persistent, to the same food. The more severe allergy is eosinophilic esophagitis (EoE), which has been increasing in recent years.

Computer engineer patents quantum computing device Posted: 28 Feb 2014 12:58 PM PST While widespread quantum computing may still be 15 years away, a computer engineering has patented a quantum processor capable of parallel computing that uses no transistors.

Physicists solve 20-year-old debate surrounding glassy surfaces Posted: 28 Feb 2014 09:13 AM PST Physicists have succeeded in measuring how the surfaces of glassy materials flow like a liquid, even when they should be solid. A series of simple and elegant experiments were the solution to a problem that has been plaguing condensed matter physicists for the past 20 years.

Peat soils as gigantic batteries Posted: 28 Feb 2014 09:13 AM PST Researchers have described a process that suppresses the formation of methane in soils that are rich in humic substances. For this process to work, the soils need to switch between having no oxygen and having oxygen.

Ease and security of password protections improved Posted: 28 Feb 2014 09:11 AM PST A new article proposes and tests four two-factor schemes that require servers to store a randomized hash of the passwords and a second device, such as the user's security token or smartphone, to store a corresponding secret code.

Brain research tracks internet safety performance, dispels assumptions, identifies traits of those at-risk Posted: 28 Feb 2014 09:11 AM PST Researchers used a novel methodology to gain new neurological insights into how users face security questions and how their personalities might affect their performance.

Unearthing key function of plant hormone Posted: 28 Feb 2014 07:34 AM PST Plants, like animals, employ hormones as messengers, which coordinate growth and regulate how they react to the environment. One of these plant hormones, auxin, regulates nearly all aspects of plant behavior and development, for example phototropism, root growth and fruit growth. Depending on the context, auxin elicits a range of responses such as cell polarization or division. Scientists now report finding the molecular mechanism by which the plant hormone auxin affects the organization of the cell's inner skeletons.
