Trio of studies support use of PET/CT scans as prostate cancer staging tool Posted: 21 Oct 2011 01:22 PM PDT Recent studies have suggested that C-11 choline positron emission tomography/computerized tomography scans can be utilized as a staging and potentially therapeutic tool in prostate cancer.

Commonly used three-drug regimen for idiopathic pulmonary fibrosis found harmful Posted: 21 Oct 2011 01:22 PM PDT A multi-center, clinical trial studying treatments for the lung-scarring disease idiopathic pulmonary fibrosis has been stopped for safety concerns. The trial found that people with IPF receiving a currently used triple-drug therapy consisting of prednisone, azathioprine, and N-acetylcysteine had worse outcomes than those who received placebos.

Psychologists defend the importance of general abilities Posted: 21 Oct 2011 01:22 PM PDT What makes a great violinist, physicist, or crossword puzzle solver? Are experts born or made? The question has intrigued psychologists since psychology was born -- and the rest of us, too, who may secretly fantasize playing duets with Yo Yo Ma or winning a Nobel Prize in science.

Why do some athletes choke under pressure? Posted: 21 Oct 2011 12:16 PM PDT Athletes know they should just do their thing on the 18th hole, or during the penalty shootout, or when they're taking a three-point shot in the last moments of the game. But when that shot could mean winning or losing, it's easy to choke. A new article looks at why paying too much attention to what you're doing can ruin performance.

Coupling of proteins promotes glioblastoma development, researchers find Posted: 21 Oct 2011 12:16 PM PDT Two previously unassociated proteins known to be overly active in a variety of cancers bind together to ignite and sustain malignant brain tumors, a research team reports.

Cooling the warming debate: Major new analysis confirms that global warming is real Posted: 21 Oct 2011 11:47 AM PDT Global warming is real, according to a major new study. Despite issues raised by climate change skeptics, the Berkeley Earth Surface Temperature study finds reliable evidence of a rise in the average world land temperature of approximately 1 degree Celsius since the mid-1950s.

US residents say Hawaii's coral reef ecosystems worth $33.57 billion per year Posted: 21 Oct 2011 10:50 AM PDT The American people assign an estimated total economic value of $33.57 billion for the coral reefs of the main Hawaiian Islands. The findings came from survey of 3,100 households -- from all US residents, not just Hawaii or coastal residents. Survey allowed the public to express its preferences and values for protection and restoration of the coral reef ecosystems around the main Hawaiian Islands.

'Trading places' most common pattern for couples dealing with male depression Posted: 21 Oct 2011 09:58 AM PDT Researchers have identified three major patterns that emerge among couples dealing with male depression. These can be described as "trading places," "business as usual" and "edgy tensions."

Housing, health care contribute most to rising costs of living in Washington State, U.S. Posted: 21 Oct 2011 09:58 AM PDT It costs 8 percent more on average than it did two years ago for Washington State residents to make ends meet, according to a new report.

Plants feel the force: How plants sense touch, gravity and other physical forces Posted: 21 Oct 2011 09:57 AM PDT At the bottom of plants' ability to sense touch, gravity or a nearby trellis are mechanosensitive channels, pores through the cells' plasma membrane that are opened and closed by the deformation of the membrane. Biologists are studying the roles these channels play in Arabdopsis plants by growing mutant plants that lack one or more of the 10 possible channel proteins in this species.

Blood-pressure-lowering drug after stroke aids recovery, study suggests Posted: 21 Oct 2011 09:57 AM PDT A commonly prescribed blood pressure-lowering medication appears to kick start recovery in the unaffected brain hemisphere after a stroke by boosting blood vessel growth, a new study has found.

Decision-making: What you want vs. how you get it Posted: 21 Oct 2011 09:57 AM PDT New research reveals how we make decisions. Birds choosing between berry bushes and investors trading stocks are faced with the same fundamental challenge -- making optimal choices in an environment featuring varying costs and benefits.

Fluoride shuttle increases storage capacity: Researchers develop new concept for rechargeable batteries Posted: 21 Oct 2011 09:55 AM PDT Researchers have developed a new concept for rechargeable batteries. Based on a fluoride shuttle -- the transfer of fluoride anions between the electrodes -- it promises to enhance the storage capacity reached by lithium-ion batteries by several factors. Operational safety is also increased, as it can be done without lithium.

Elderly long-term care residents suffer cognitively during disasters Posted: 21 Oct 2011 09:55 AM PDT In a summer with unprecedented weather events, from tornadoes, floods, fires and hurricanes, researchers found that physiological changes associated with aging and the presence of chronic illness make older adults more susceptible to illness or injury, even death, during a disaster.

Biomarker detects graft-versus-host-disease in cancer patients after bone marrow transplant Posted: 21 Oct 2011 09:55 AM PDT A team of researchers has found a biomarker they believe can help rapidly identify one of the most serious complications in cancer patients after a bone marrow transplant.

Vivid descriptions of faces 'don't have to go into detail' Posted: 21 Oct 2011 09:55 AM PDT Celebrated writers such as Charles Dickens and George Eliot described characters' faces vividly without going into detail about their features, according to researchers.

How do protein binding sites stay dry in water? Posted: 21 Oct 2011 09:51 AM PDT Researchers studied the condition for model cavity and tunnel structures resembling the binding sites of proteins to stay dry without losing their ability to react, a prerequisite for proteins to establish stable interactions with other proteins in water.

Aggregating bandwidth for faster mobile networks Posted: 21 Oct 2011 09:51 AM PDT A new study reveals that the value of mobile spectrum, the capacity to transfer data across mobile networks, is only likely to increase as the demand for data transfer increases. However, it is only those telecommunications companies that bought up in government auctions the inexpensive licenses to operate at particularly frequencies of the spectrum that will be in strong position to dominate in the consumer and enterprise markets.

Plate tectonics may control reversals in Earth's magnetic field Posted: 21 Oct 2011 05:45 AM PDT Earth's magnetic field has reversed many times at an irregular rate throughout its history. Long periods without reversal have been interspersed with eras of frequent reversals. What is the reason for these reversals and their irregularity? Researchers have shed new light on the issue by demonstrating that, over the last 300 million years, reversal frequency has depended on the distribution of tectonic plates on the surface of the globe. This result does not imply that terrestrial plates themselves trigger the switch over of the magnetic field. Instead, it establishes that although the reversal phenomenon takes place, in fine, within Earth's liquid core, it is nevertheless sensitive to what happens outside the core and more specifically in Earth's mantle.

New mechanism inhibiting the spread and growth of cancer found in motile cells Posted: 21 Oct 2011 05:45 AM PDT A revolutionary discovery regarding motile cancer cells is challenging previous conceptions.

Florida Keys ecosystem threatened by multiple stressors Posted: 21 Oct 2011 04:47 AM PDT Scientists have found that pressure from increasing coastal populations, ship and boat groundings, marine debris, poaching, and climate change are critically threatening the health of the Florida Keys ecosystem.

Elaborate bird plumage due to testosterone? Posted: 21 Oct 2011 04:47 AM PDT In many bird species males have a more elaborate plumage than females. This elaborate plumage is often used to signal body condition, to intimidate rivals or to attract potential mates. In many cases plumage colouration also depends on the hormone testosterone. Researchers have now investigated whether this also holds true for sex role-reversed bird species.

Simple lifestyle changes can add a decade or more healthy years to the average lifespan, Canadian study shows Posted: 21 Oct 2011 04:47 AM PDT Health prevention strategies to help people achieve their optimal health potential could add a decade or more of healthy years to the average lifespan and save the economy billions of dollars as a result of reduced cardiovascular disease.

Issues faced by friends and family of the suicidal Posted: 21 Oct 2011 04:47 AM PDT A study focusing on the family and friends of people who were suicidal has highlighted the main challenges they face when trying to judge whether a person is in danger and decide what they should do about it.

Poor cerebral cortex functions leads to more impulsive behavior Posted: 21 Oct 2011 04:46 AM PDT If the front part of the cerebral cortex is less active then people have less control over their social behavior and automatically follow their inclinations more. The research was the first to make use of magnetic stimulation (TMS) to suppress this part at the front of the prefrontal cortex. During TMS a changing magnetic field on the head temporarily influences the activity of the underlying part of the brain.

Boosting mental performance with fish oil? Posted: 21 Oct 2011 04:46 AM PDT A particular fish oil (omega-3) supplement has been shown to improve blood flow to the brain during mental activity and to impact on certain aspects of mental performance in young adults, according to new research.

Likely reason for neurological injuries in children Posted: 21 Oct 2011 04:45 AM PDT Scientists have discovered new pathways of neurons migrating from lateral ventricles to the prefrontal cortex. The work done in children at early ages reveals a new cell pathway which may increase the amount of neurons in regions important for cognitive tasks, emotional processes and spatial perception.

Digital worlds can help autistic children to develop social skills Posted: 21 Oct 2011 04:45 AM PDT The benefits of virtual worlds can be used to help autistic children develop social skills beyond their anticipated levels, suggest early findings from new research. Researchers have developed an interactive environment which uses multi-touch screen technology where virtual characters on the screen demonstrate gestures and show children's actions in real time.

New study shows no simultaneous warming of northern and southern hemispheres as a result of climate change for 20,000 years Posted: 21 Oct 2011 04:45 AM PDT A common argument against global warming is that the climate has always varied. Temperatures rise sometimes and this is perfectly natural is the usual line. However, a climate researcher has now shown that global warming, i.e. simultaneous warming events in the northern and southern hemispheres, have not occurred in the past 20 000 years, which is as far back as it is possible to analyze with sufficient precision to compare with modern developments.

Seeking answers to treat the fear of childbirth Posted: 21 Oct 2011 04:45 AM PDT One of five Norwegian women suffers from a fear of childbirth. This fear increases health risks to mother and child, results in more planned and emergency Caesarean sections and consumes substantial resources at hospitals. Now researchers are looking for the causes.

First Ebola-like virus native to Europe discovered Posted: 20 Oct 2011 04:18 PM PDT Researchers have discovered a new Ebola-like virus -- Lloviu virus -- in bats from northern Spain. Lloviu virus is the first known filovirus native to Europe. Filoviruses, which include well-known viruses like Ebola and Marburg, are among the deadliest pathogens in humans and non-human primates, and are generally found in East Africa and the Philippines. The findings thus expand the natural geographical distribution of filoviruses.

Giant flakes make graphene oxide gel: Discovery could boost metamaterials, high-strength fibers Posted: 20 Oct 2011 02:14 PM PDT Slices of graphene oxide in a solution arrange themselves into a nematic liquid crystal. At a sufficient concentration, giant flakes will form a gel, a precursor to manufacturing metamaterals and fibers.

Hunters present in North America at least 800 years earlier than previously thought Posted: 20 Oct 2011 11:51 AM PDT The tip of a bone point fragment found embedded in a mastodon rib from an archaeological site in Washington state shows that hunters were present in North America at least 800 years before Clovis, confirming that the first inhabitants arrived earlier to North America than previously thought, says a team of researchers.
