Super-sized muscle made twin-horned dinosaur a speedster Posted: 14 Oct 2011 06:24 PM PDT A meat-eating dinosaur that terrorized its plant-eating neighbors in South America was a lot deadlier than first thought, a researcher has found. Carnotaurus was a seven-meter-long predator with a huge tail muscle that paleontologists say made it one of the fastest running hunters of its time.

Psychopathic killers: Computerized text analysis uncovers the word patterns of a predator Posted: 14 Oct 2011 11:51 AM PDT As words can be the soul's window, scientists are learning to peer through it: Computerized text analysis shows that psychopathic killers make identifiable word choices -- beyond conscious control -- when talking about their crimes. This research could lead to new tools for diagnosis and treatment, and have implications law enforcement and social media.

Frustration inspires new form of graphene Posted: 14 Oct 2011 11:26 AM PDT Researchers have now developed a new form of graphene that does not stack. The new material -- inspired by a trash can full of crumpled-up papers -- is made by crumpling the graphene sheets into balls.

Imaging technology might help doctors determine best treatment for Crohn's disease patients Posted: 14 Oct 2011 11:26 AM PDT Ultrasound elasticity imaging, or UEI, could allow doctors to non-invasively make the distinction between intestinal inflammation and fibrosis in Crohn's disease patients, allowing patients to receive more appropriate and timely care.

MRIs could become powerful tools for monitoring cholesteral therapy Posted: 14 Oct 2011 10:24 AM PDT MRI scanning could become a powerful new tool for assessing how well cholesterol drugs are working, according to a cardiologist studying patients taking cholesterol medications.

Gender differences in blood pressure appears as early as adolescence, with girls faring worse Posted: 14 Oct 2011 09:30 AM PDT The female hormone estrogen is known to offer protection for the heart, but obesity may be taking away that edge in adolescent girls. New research finds that although obesity does not help teens of either gender, it has a greater impact on girls' blood pressure than it does on boys'.

New study finds 400,000 farmers in southern Africa using 'fertilizer trees' to improve food security Posted: 14 Oct 2011 09:23 AM PDT On a continent battered by weather extremes, famine and record food prices, new research documents an exciting new trend in which hundreds of thousands of poor farmers in Southern Africa are now significantly boosting yields and incomes simply by using fast growing trees and shrubs to naturally fertilize their fields.

A hidden order unraveled: Microscopic views on quantum fluctuations Posted: 14 Oct 2011 09:23 AM PDT Fluctuations are fundamental to many physical phenomena in our everyday lives. Using a high resolution microscope, scientists have now been able to image quantum-correlated particle-hole pairs in a gas of ultracold atoms. This has allowed the physicists to unravel a hidden order in the crystal.

Differing structures underlie differing brain rhythms in healthy and ill, virtual modeling reveals Posted: 14 Oct 2011 07:49 AM PDT Virtual brains modeling epilepsy and schizophrenia display less complexity among functional connections, and other differences compared to healthy brain models, researchers report. The researchers worked backward from brain rhythms -- the oscillating patterns of electrical activity in the brain recorded on electroencephalograms -- from both healthy and ill individuals.

Brain scans reveal drugs' effects on attention Posted: 14 Oct 2011 07:49 AM PDT Scientists have developed a way to evaluate new treatments for some forms of attention deficit disorder. Working in mice, researchers showed that they can use brain scans to quickly test whether drugs increase levels of a brain chemical known as dopamine.

Breastfeeding reduces the risk of allergies, study suggests Posted: 14 Oct 2011 07:44 AM PDT Today, about one in four European children suffer from allergy, which makes this disease the non-infectious epidemic of the 21st century. Evidence suggests that lifestyle factors and nutritional patterns, such as breastfeeding, help to reduce the early symptoms of allergy.

Researchers discover material with graphene-like properties Posted: 14 Oct 2011 06:56 AM PDT After the Nobel Prize in Physics was awarded to two scientists in 2010 who had studied the material graphene, this substance has received a lot of attention. Scientists have now developed and analyzed a material which possesses physical properties similar to graphene.

Women's heart disease tied to small blood vessels Posted: 14 Oct 2011 06:56 AM PDT After a heart attack, women's hearts are more likely to maintain their systolic function -- their ability to contract and pump blood from the chambers into the arteries. According to researchers, this suggests that heart disease manifests differently in women, affecting the microvasculature (small blood vessels) instead of the macrovasculature (major blood vessels) as it does in men.

One in six mobile phones in the UK is contaminated with fecal bacteria, researchers found Posted: 14 Oct 2011 05:05 AM PDT One in six mobile phones in Britain is contaminated with fecal matter, according to new research. Experts say the most likely reason for the potentially harmful bacteria festering on so many gadgets is people failing to wash their hands properly with soap after going to the toilet.

Redox flow batteries, a promising technology for renewable energies integration Posted: 14 Oct 2011 05:00 AM PDT Today there is a wide variety of energy storage technologies at very different stages of development. Among them, the Redox Flow Battery (RFB) is an innovative solution based on the use of liquid electrolytes stored in tanks and pumped through a reactor to produce energy. Researchers are currently working in the development of high performance RFBs.

Mobile electrons multiplied in quantum dot films Posted: 14 Oct 2011 05:00 AM PDT Researchers have demonstrated that several mobile electrons can be produced by the absorption of a single light particle in films of coupled quantum dots. These multiple electrons can be harvested in solar cells with increased efficiency.

Cells have early-warning system for intruders Posted: 14 Oct 2011 05:00 AM PDT When a thief breaks into a bank vault, sensors are activated and the alarm is raised. Cells have their own early-warning system for intruders, and scientists have discovered how a particular protein sounds that alarm when it detects invading viruses. The study is a key development in our understanding of the innate immune response, shedding light on how cells rapidly respond to a wide range of viruses including influenza, rabies and hepatitis.

Watching motion of electrons in molecules during chemical reactions Posted: 14 Oct 2011 05:00 AM PDT Scientists have, for the first time, visualized the motion of electrons during a chemical reaction. The new findings in the experiment are of fundamental importance for photochemistry and could also assist the design of more efficient solar cells.

How touch and movement contribute to the development of the brain Posted: 14 Oct 2011 05:00 AM PDT Neuroscientists have uncovered in an animal model the neuronal processes that underlay the development of sensory maps in the developing brain.
