| Mouth bacteria can change its diet, supercomputers reveal Posted: 12 Aug 2014 01:38 PM PDT Mouth bacteria can change their metabolism in disease versus health. The Stampede and Lonestar supercomputers compared gene expression of 160,000 genes in healthy and diseased periodontal communities. Research paves way for biomarkers to predict illness from wide-ranging diseases such as periodontitis, diabetes, and Crohn's disease.       |
| Rare blurring of black hole light spotted Posted: 12 Aug 2014 11:20 AM PDT Scientists have captured an extreme and rare event in the regions immediately surrounding a supermassive black hole. A compact source of X-rays that sits near the black hole, called the corona, has moved closer to the black hole over a period of just days.  |
| Focal blood-brain-barrier disruption with high-frequency pulsed electric fields Posted: 12 Aug 2014 09:24 AM PDT A novel method uses bursts of nanosecond duration electric pulses to open the blood-brain barrier as a potential therapy for brain cancer and neurological disorders. The Vascular Enabled Integrated Nanosecond pulse (VEIN pulse) procedure consists of inserting minimally invasive needle electrodes into the diseased tissue and applying multiple bursts of nanosecond pulses with alternating polarity.  |
| Stability of wonder material silicene demonstrated Posted: 12 Aug 2014 09:23 AM PDT An international team of researchers has taken a significant step towards understanding the fundamental properties of the two-dimensional material silicene by showing that it can remain stable in the presence of oxygen.  |
| Pioneering online treatment for people with bipolar disorder Posted: 12 Aug 2014 09:18 AM PDT The first effective web-based treatment for Bipolar Disorder based on the latest research evidence has been developed by psychologists. 92% of the participants in the trial of the online intervention found the content positive -- and one said it had changed her life. People with Bipolar Disorder have problems getting access to psychological therapy and this online intervention may offer a round the clock solution at a reduced cost.  |
| Our ancestor's 'leaky' membrane answers big questions in biology Posted: 12 Aug 2014 09:17 AM PDT All life on Earth came from one common ancestor -- a single-celled organism -- but what it looked like, how it lived and how it evolved into today's modern cells is a four billion year old mystery being solved by researchers at using mathematical modelling. Findings suggest for the first time that life's Last Universal Common Ancestor (LUCA) had a 'leaky' membrane, which helps scientists answer two of biology's biggest questions.  |
| Neutrino detectors could help detect nuclear weapons Posted: 12 Aug 2014 09:16 AM PDT Physicists at the Large Hadron Collider in Switzerland and even in the fictional world of CBS' "The Big Bang Theory" look to subatomic particles called neutrinos to answer the big questions about the universe. Scientists now believe neutrinos could be used to monitor nuclear power plants for signs of nuclear proliferation.  |
| Stinky gases emanating from landfills could transform into clean energy Posted: 12 Aug 2014 09:16 AM PDT A new technique transforming stinky, air-polluting landfill gas could produce the sweet smell of success as it leads to development of a fuel cell generating clean electricity for homes, offices and hospitals, researchers say. The advance would convert methane gas into hydrogen, an efficient, clean form of energy.  |
| Could hemp nanosheets topple graphene for making the ideal supercapacitor? Posted: 12 Aug 2014 09:15 AM PDT As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors.  |
| Sniffing out billions in U.S. currency smuggled across the border to Mexico Posted: 12 Aug 2014 09:15 AM PDT Criminals are smuggling an estimated $30 billion in U.S. currency into Mexico each year from the United States, but help could be on the way for border guards, researchers report. The answer to the problem: a portable device that identifies specific vapors emitted by U.S. paper money, to be described by researchers.  |
| Groundbreaking approach to understanding social interaction Posted: 11 Aug 2014 02:00 PM PDT Scientists have created the Human Dynamic Clamp to address the difficult problem of studying social interactions in the laboratory. Using state-of-the-art human-machine interface technology, the Human Dynamic Clamp works by having humans interact with a computational model that behaves very much like humans themselves. In simple experiments, the model – on receiving input from human movement – drives an image of a moving hand which is displayed on a video screen.  |
| Helping farmers adapt to changing growing conditions Posted: 11 Aug 2014 10:22 AM PDT Spring rains that delayed planting and a cool summer have farmers concerned about whether their corn will reach maturity before the first frost. Two new online decision-making tools available through the U.S. Department of Agriculture's Useful to Usable research project will help, according to a state climatologist. Farmers are producing crops under more variable conditions, so these tools can be critical to both food safety and the farmers' economic survival.  |
| Customized surface inspection integrated into production process Posted: 11 Aug 2014 09:46 AM PDT The quality control of component surfaces is a complex undertaking. Researchers have engineered a high-precision modular inspection system that can be adapted on a customer-specific basis and integrated into the production process.  |
