Psychological scientists are exploring the mechanisms that underlie memory to understand why we remember certain things and why we forget others. Read about the latest research on memory published in the November 2012 issue of Psychological Science. Retrieval-Induced Forgetting Predicts Failure to Recall Negative Autobiographical Memories Failure to retrieve memories may not always be a bad thing - we might, for example, prefer to forget about certain instances of heartbreak or failure in favor of some of the more positive events from our lives. In this study, researchers ...

Fire the coach? Not so fast says a new study of elite college football teams. Professors from the University of Colorado and Loyola University Chicago studied what happened to the records of college football teams that replaced a head coach for performance reasons in the Football Bowl Subdivision (formerly Division 1-A) between 1997 and 2010. Over this period, an average of 10 percent of FBS teams fired their coach each year because of the team's poor performance on the field. The authors used statistical methods to compare groups of teams that were similar except for ...

New research from Georgia Aquarium and Georgia Institute of Technology provides evidence that a suite of techniques called "metabolomics" can be used to determine the health status of whale sharks (Rhincodon typus), the world's largest fish species. The study, led by Dr. Alistair Dove, Director of Research & Conservation at Georgia Aquarium and an adjunct professor at Georgia Tech, found that the major difference between healthy and unhealthy sharks was the concentration of homarine in their in serum—indicating that homarine is a useful biomarker of health status for the ...

CCS is a process consisting of the separation of CO2 from industrial and energy-related sources, transport to a storage ...

PASADENA, Calif.—In order to build the next generation of nuclear reactors, materials scientists are trying to unlock the secrets of certain materials that are radiation-damage tolerant. Now researchers at the California Institute of Technology (Caltech) have brought new understanding to one of those secrets—how the interfaces between two carefully selected metals can absorb, or heal, radiation damage. "When it comes to selecting proper structural materials for advanced nuclear reactors, it is crucial that we understand radiation damage and its effects on materials properties. ...

Ethanol, a component of biofuel made from plants such as corn, is blended with gas in many parts of the country, but has significantly different fluid properties than pure gasoline. A group of researchers from the University of Michigan wondered how ethanol-based fuels would spread in the event of a large aquatic spill. They found that ethanol-based liquids mix actively with water, very different from how pure gasoline interacts with water and potentially more dangerous to aquatic life. The scientists will present their results, which could impact the response guidelines ...

To help planes fly safely through cold, wet, and icy conditions, a team of Japanese scientists has developed a new super water-repellent surface that can prevent ice from forming in these harsh atmospheric conditions. Unlike current inflight anti-icing techniques, the researchers envision applying this new anti-icing method to an entire aircraft like a coat of paint. As airplanes fly through clouds of super-cooled water droplets, areas around the nose, the leading edges of the wings, and the engine cones experience low airflow, says Hirotaka Sakaue, a researcher in the ...

Small floating objects change the dynamics of the surface they are on. This is an effect every serious student of breakfast has seen as rafts of floating cereal o's arrange and rearrange themselves into patterns on the milk. Now scientists have suggested that this process may offer insight into nanoscale engineering processes. "Small objects floating on the fluid-air interface deform the surface and attract each other through capillary interactions, a phenomenon dubbed `The Cheerios Effect,''' explains student Khoi Nguyen. "Interesting motions occur here caused by attractive ...

A new study by researchers at Imperial College London has identified a way in which Salmonella bacteria, which cause gastroenteritis and typhoid fever, counteract the defence mechanisms of human cells. One way in which our cells fight off infections is by engulfing the smaller bacterial cells and then attacking them with toxic enzymes contained in small packets called lysosomes. Published today (Thursday) in Science, the study has shown that Salmonella protects itself from this attack by depleting the supply of toxic enzymes. Lysosomes constantly need to be replenished ...

Researchers have pieced together new genetic clues to the arthritis puzzle in a study that brings potential treatments closer to reality and could also provide insights into why more women than men succumb to the disabling condition. Rheumatoid arthritis – which affects more than 400,000 people in the UK and about 1% of the world's population – is a complicated disease: lifestyle and environmental factors, such as smoking, diet, pregnancy and infection are thought to play a role, but it is also known that a person's genetic makeup influences their susceptibility to the ...

TALLAHASSEE, Fla. Portions of Albert Einstein's brain have been found to be unlike those of most people and could be related to his extraordinary cognitive abilities, according to a new study led by Florida State University evolutionary anthropologist Dean Falk. Falk, along with colleagues Frederick E. Lepore of the Robert Wood Johnson Medical School and Adrianne Noe, director of the National Museum of Health and Medicine, describe for the first time the entire cerebral cortex of Einstein's brain from an examination of 14 recently discovered photographs. The researchers ...

DENVER – Targeted cancer therapy has been transforming the care of patients with non-small-cell lung cancer (NSCLC). It is now standard practice for tumor specimens from NSCLC patients to be examined for EGFR mutations and ALK rearrangements to identify patients for therapy with EGFR and ALK inhibitors, respectively. Now, researchers say large-scale genomic testing is feasible within the clinical workflow, impacting therapeutic decisions. The study is published in the December 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of ...

DENVER – It is common for patients initially diagnosed with lung cancer to have the cancer spread to sites like the liver, brain and bone. One of the most frequent sites of metastases is the bone, with an estimated 30 to 40 percent of patients with non-small-cell lung cancer (NSCLC) developing bone loss. A study published in the December 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology, shows that the bone metastases drug denosumab was associated with improved overall survival compared with zoledonic acid (ZA). ...

Lawrence Livermore National Laboratory researchers are making key contributions to a physics experiment that will look for one of nature's most elusive particles, "dark matter," using a tank nearly a mile underground beneath the Black Hills of South Dakota. The Large Underground Xenon (LUX) experiment located at the Sanford Underground Research Facility in Lead, S.D. is the most sensitive detector of its kind to look for dark matter. Thought to comprise more than 80 percent of the mass of the universe, scientists believe dark matter could hold the key to answering some ...

CHAMPAIGN, Ill. — Cellphones and driving go together like knives and juggling. But when cellphone use is banned, are drivers any safer? It depends on where you're driving, a study by University of Illinois researchers says. The study found that, long-term, enacting a cellphone ban was associated with a relative decrease in the accident rate in urban areas. However, in very rural areas, cellphone bans were associated with higher accident rates than would otherwise be expected. "The main idea is to use the eye test when it comes to cellphone use," says study leader ...

RICHLAND, Wash. -- Pollution from fossil fuel burning and forest fires reaches all the way to the Arctic, even though it should decay long before it travels that far. Now, lab research can explain how pollution makes its lofty journey: rather than ride on the surface of airborne particles, pollutants snuggle inside, protected from the elements on the way. The results will help scientists improve atmospheric air-quality and pollution transport models. The results also show that the particles that envelop pollutants also benefit from this arrangement. The new study in Environmental ...

Researchers at the McCormick School of Engineering are part of a team that has used stretchable electronics to create a multipurpose medical catheter that can both monitor heart functions and perform corrections on heart tissue during surgery. The device marks the first time stretchable electronics have been applied to a surgical process known as cardiac ablation, a milestone that could lead to simpler surgeries for arrhythmia and other heart conditions. The researchers had previously demonstrated the concept to apply stretchable electronics to heart surgery, but with ...

CORVALLIS, Ore. – Electrical engineers at Oregon State University have developed new technology to monitor medical vital signs, with sophisticated sensors so small and cheap they could fit onto a bandage, be manufactured in high volumes and cost less than a quarter. A patent is being processed for the monitoring system and it's now ready for clinical trials, researchers say. When commercialized, it could be used as a disposable electronic sensor, with many potential applications due to its powerful performance, small size, and low cost. Heart monitoring is one obvious ...

Magnetotactic bacteria, like Magnetospirillum magneticum, have evolved cellular processes that allow them to take up iron molecules to produce magnetic nanocrystals like magnetite. Since they were first discovered and isolated in 1975 by Robert Blakemore, scientists continue to be fascinated by these unique bacteria, whether as a means to isolate biogenic magnetite or to understand the evolutionary advantages of producing these minerals. A new video-article in JoVE (Journal of Visualized Experiments) details a procedure to purify and enrich samples of magnetotactic bacteria ...

Last March, researchers at UCLA reported the development of a molecular compound called CLR01 that prevented toxic proteins associated with Parkinson's disease from binding together and killing the brain's neurons. Building on those findings, they have now turned their attention to Alzheimer's disease, which is thought to be caused by a similar toxic aggregation or clumping, but with different proteins, especially amyloid-beta and tau. And what they've found is encouraging. Using the same compound, which they've dubbed a "molecular tweezer," in a living mouse model ...

PULLMAN, Wash.—Washington State University researchers have found an unlikely recipe for antibiotic resistant bacteria: Mix cow dung and soil, and add urine infused with metabolized antibiotic. The urine will kill off normal E. coli in the dung-soil mixture. But antibiotic-resistant E. coli will survive in the soil to recolonize in a cow's gut through pasture, forage or bedding. "I was surprised at how well this works, but it was not a surprise that it could be happening," says Doug Call, a molecular epidemiologist in WSU's Paul G. Allen School for Global Animal Health. ...

What can high school and college-age video game enthusiasts teach young surgeons-in-training? According to a new study from researchers at the University of Texas Medical Branch at Galveston (UTMB) – a world leader in minimally invasive and robotic surgery – the superior hand-eye coordination and hand skills gained from hours of repetitive joystick maneuvers mimic the abilities needed to perform today's most technologically-advanced robotic surgeries. To offer insight on how best to train future surgeons, the study placed high school and college students head to head ...

Some arid lands in the American West degraded by military exercises that date back to General George Patton's Word War II maneuvers in the Mojave Desert should get a boost from an innovative research project led by the University of Colorado Boulder. Headed up by CU-Boulder Assistant Professor Nichole Barger, the research team is focused on developing methods to restore biological soil crusts -- microbial communities primarily concentrated on soil surfaces critical to decreasing erosion and increasing water retention and soil fertility. Such biological soil crusts, known ...

By combining the power of the NASA/ESA Hubble Space Telescope, NASA's Spitzer Space Telescope and one of nature's zoom lenses, astronomers have found what is probably the most distant galaxy yet seen in the Universe. The object offers a peek back into a time when the Universe was only 3 percent of its present age of 13.7 billion years. We see the newly discovered galaxy, named MACS0647-JD, as it was 420 million years after the Big Bang. Its light has travelled for 13.3 billion years to reach Earth, which corresponds to a redshift of approximately 11 [1]. This is the ...
