First Complete X-ray View Of A Galaxy Cluster Posted: 31 May 2009 05:00 PM PDT The joint Japan-US Suzaku mission is providing new insight into how assemblages of thousands of galaxies pull themselves together. For the first time, Suzaku has detected X-ray-emitting gas at a cluster's outskirts, where a billion-year plunge to the center begins.

Eight Newly Identified Genes Help Predict A Melanoma Patient's Response To Treatment Posted: 31 May 2009 05:00 PM PDT Eight newly identified genes help predict a melanoma patient's response to treatment, a new study suggests.

Toward Cheap Underwater Sensor Nets Posted: 31 May 2009 05:00 PM PDT Computer scientists are one step closer to building low cost networks of underwater sensors for real time underwater environmental monitoring. New research highlights the energy conservation benefits of using reconfigurable hardware rather than competing hardware platforms for their experimental underwater sensor nets.

Childhood Cancer Survivors Have Persistent High Risk For Cancer Throughout Their Lives Posted: 31 May 2009 05:00 PM PDT Childhood cancer survivors have a persistent and high risk for a second primary cancer throughout their lives, according to a new study.

Probing Clouds' Roles In Global Electric Circuit Posted: 31 May 2009 05:00 PM PDT A semicontinuous current flow has been measured above electrified clouds. Called the Wilson current, this phenomenon has long been considered a critical component of the global electric circuit; however, only a few studies have directly investigated this current, yielding only a few dozen measurements.

Ballerinas And Female Athletes Share Quadruple Health Threats Posted: 31 May 2009 05:00 PM PDT Sports medicine researchers have found that young female professional dancers face the same health risks as young female athletes when they don't eat enough to offset the energy they spend, and stop menstruating as a consequence.

Why Can We Talk? 'Humanized' Mice Speak Volumes About Evolutionary Past Posted: 31 May 2009 11:00 AM PDT Mice carrying a "humanized version" of a gene believed to influence speech and language may not actually talk, but they nonetheless do have a lot to say about our evolutionary past, according to a new report.

Brain Waves: How Neuronal Activity Is Timed In Brain's Memory-making Circuits Posted: 31 May 2009 11:00 AM PDT Theta oscillations are a type of brain rhythm that orchestrates neuronal activity in the hippocampus, a brain area critical for the formation of new memories. For several decades these oscillations were believed to be "in sync" across the hippocampus, timing the firing of neurons like a sort of central pacemaker. Researchers show that instead of being in sync, theta oscillations sweep along the length of the hippocampus as traveling waves.

Cotton Bests Other Spray-On Erosion Control Mulches Posted: 31 May 2009 11:00 AM PDT Agricultural engineers have developed the erosion control industry's first cotton hydromulch "spray-on blanket." Hydromulch is the bright-green mulch used in spray-on slurries that cover bare lands at construction sites and roadside projects, to prevent erosion until vegetation can be established. In the past, hydromulches were made mostly from wood and paper byproducts.

PET Scan Can Non-Invasively Measure Early Assessment Of Treatment For Common Type Of Breast Cancer Posted: 31 May 2009 11:00 AM PDT Non-invasive imaging can measure how well patients with the most common form of breast cancer -- estrogen receptor positive type -- respond to standard aromatase inhibitor therapy after only two weeks and shows similar findings that more invasive needle sampling identifies, according to new research.

Waves In Earth's Radiation Belt Get Mapped Posted: 31 May 2009 11:00 AM PDT Chorus waves, a type of electromagnetic emission generated by electrons in Earth's radiation belt, play an important role in both accelerating and removing the energetic radiation belt electrons that can disrupt satellite electronics and disturb communications with ground-based operators.

Staying Together 'For The Sake Of The Kids' Doesn't Necessarily Help Them, Says Study Posted: 31 May 2009 11:00 AM PDT The research is clear: Adolescents tend to fare better -- academically and behaviorally -- when they live with both biological parents. But when their parents frequently argue, young adults are significantly more likely to binge drink than other teenagers. They also tend to smoke, and their poor school grades are similar to those of their peers who don't have both biological parents at home.

Breakthrough In Quantum Control Of Light: Implications For Banking, Drug Design, And More Posted: 31 May 2009 05:00 AM PDT Researchers have recently demonstrated a breakthrough in the quantum control of photons, the energy quanta of light. This is a significant result in quantum computation, and could eventually have implications in banking, drug design, and other applications.

Intestinal Bacteria Associated With Non-alcoholic Fatty Liver Disease Posted: 31 May 2009 05:00 AM PDT Intestinal permeability and an overgrowth of bacteria in the small intestine are both associated with non-alcoholic fatty liver disease, according to new findings.

TB -- Hiding In Plain Sight Posted: 31 May 2009 05:00 AM PDT Current research suggests that Mycobacterium tuberculosis can evade the immune response. The related report by Rahman et al., "Compartmentalization of immune responses in human tuberculosis: few CD8+ effector T cells but elevated levels of FoxP3+ regulatory T cells in the granulomatous lesions," appears in the June 2009 issue of the American Journal of Pathology.

Continuous Glucose Monitoring Devices Benefit People With Type 1 Diabetes Posted: 31 May 2009 05:00 AM PDT People with type 1 diabetes who have already been successful in achieving recommended blood sugar goals can further benefit from using continuous glucose monitoring (CGM) devices, according to results of a major multi-center clinical trial.

Satellites Observe Amazon Basin Water Storage And Runoff Posted: 31 May 2009 05:00 AM PDT Scientists would like to better understand the physical processes in Amazon hydrological systems. To explore the water storage and dynamics in the Amazon basin, researchers have used data from the two Gravity Recovery and Climate Experiment (GRACE) satellites, which measure mass distribution on Earth's surface through instantaneous measurements of the changes in the distance between the satellites.

'Charm' Offensive Could Pinpoint Ways To Change People's Social Habits Posted: 31 May 2009 05:00 AM PDT People like to believe their actions are driven by their own free will and are not unduly affected by other people. Research, though, shows the way we act is often subconsciously influenced by what we believe to be 'normal' behavior. A new research project is about to take this finding to the next level by investigating whether it is possible to nudge individual behavior in a socially-desirable direction, simply by telling people what others are doing.

Scientists Engineer Cellular Circuits That Count Events Posted: 30 May 2009 11:00 PM PDT Engineers have designed cells that can count and "remember" cellular events, using simple circuits in which a series of genes are activated in a specific order.

New Broad-spectrum Vaccine To Prevent Cervical Cancer Induces Strong Responses In Animals Posted: 30 May 2009 11:00 PM PDT Mice and rabbits immunized with a multimeric-L2 protein vaccine had robust antibody responses and were protected from infection when exposed to human papillomavirus type 16 four months after vaccination, according to a new study.

Parasite Risk In Anchovies Varies Depending On Origin Of Fish Posted: 30 May 2009 11:00 PM PDT The Anisakis spp parasite can still be found in one of the most emblematic Mediterranean dishes -- anchovies in vinegar. Spanish researchers have shown the parasites are present at higher levels in anchovies from the south east Atlantic coast and the north eastern Mediterranean, and urge consumers to freeze or cook the fish before eating it.

Biological Markers That May Indicate Poor Breast Cancer Prognosis Identified Posted: 30 May 2009 11:00 PM PDT Scientists have identified two proteins in the blood that could become important prognostic markers for long-term survival in breast cancer patients. The proteins are associated with chronic inflammation, which is known to contribute to cancer development and progression.

First Multi-pixel Terahertz Modulator Created Posted: 30 May 2009 11:00 PM PDT Scientists have for the first time devised a multi-pixel modulator for light waves at terahertz frequencies. The formal study of THz radiation, which can be described as far-infrared light, dates back many years, but has become increasingly widespread since around 1990, when efficient methods for generating and detecting the radiation become available. The expected applications include carrying out biological spectroscopy and imaging buried structures in semiconductors.

Unstated Assumptions Color Arctic Sovereignty Claims Posted: 30 May 2009 11:00 PM PDT Settling the growing debate over ownership of Arctic Ocean resources is complicated by the fact that the various countries involved have different understandings of the geography of the place, one researcher argues.

Genetic Profiling Reveals Genes Active In The Earliest Brain Circuit Construction Posted: 29 May 2009 09:00 PM PDT Long before the brain's neurons can facilitate life's big decisions, they have to find their own destiny in the rapidly developing embryo. In the lingo of neurobiologists, they are "fated" very early on to become certain types of cells, over time traveling to and organizing the various structures that compose the brain. These earliest developments are difficult to observe, like the first few moments in the life of the universe following the Big Bang. But by adapting new tools of genetic profiling, researchers have peered into the brain as it's born and teased out genes that shape its aboriginal fate.

To Spread, Skin Cancer Attacks Immune Dendritic Cells Posted: 29 May 2009 09:00 PM PDT Dendritic cells are the sentinels of the immune system. When they're alert and on guard, they will marshal the body's immunosoldiers, T cells, to battle at the sight of harmful pathogens. But some diseases, such as cancer, are able to escape their watchful eye. By knocking out or beguiling dendritic cells, they slip the defenses of the immune system and sack the unsuspecting body.

Illegal Trade In Vietnam's Marine Turtles Continues Despite National Ban Posted: 29 May 2009 09:00 PM PDT Marine turtles are vanishing from Viet Nam's waters and illegal trade is largely to blame says a new study.

Predicting Droughts With Greater Certainty Posted: 29 May 2009 09:00 PM PDT Using new data and reconstructions of the "Dust Bowl" drought in America during the 1930s, climatologists have shown for the first time a three-dimensional picture of the atmospheric circulation that led to the drought. This will enable climate models to be evaluated and further improved. The scientists hope this work will make it possible to predict future periods of drought more accurately.

Hearing, Voice Problems Worsen Seniors' Communication Skills Posted: 29 May 2009 09:00 PM PDT Hearing and vocal problems go hand-in-hand among the elderly more frequently than previously thought, according to researchers. Together, they pack a devastating double punch on communication skills and overall well-being.

Drug Combination Improves Outcome For Advanced Non-small Cell Lung Cancer Posted: 29 May 2009 09:00 PM PDT A new study found that the combination of two drugs delays disease progression for patients with advanced non-small cell lung cancer. Results from the Phase III "ATLAS" trial have just been presented.
