(October 12, 2012) In a new study published in Frontiers, Dr Timothy Durazzo and colleagues from the San Francisco VA Medical Center and University of California, San Francisco, expand upon their decade of research showing that smoking while kicking the alcohol habit impairs memory, learning and other cognitive skills--ultimately making it more difficult to weather the long storm of sobriety. Cigarettes, substance abuse and the military "Given our strong and consistent research findings in both Veterans and civilians on the ill-effects of chronic smoking, we truly hope ...

Despite Pittsburgh's mass exodus of young people in the 1980s, data released today by the University of Pittsburgh's University Center for Social and Urban Research and PittsburghTODAY show that over the past five years Pittsburgh has seen a seven percent influx of young people ages 20-34. The report, Young Adults Report 2012, draws the most comprehensive profile to date of the young men and women in the 32-county Pittsburgh region. Findings are based onPittsburghTODAY's reporting, as well as on an extensive regional survey and focus groups conducted jointly by the University ...

Lance Armstrong's doping scandal may be considered by U.S. Anti-Doping Agency (USADA) as "more extensive than any previously revealed in professional sports history," but a new editorial in The FASEB Journal (http://www.fasebj.org) by USADA's Larry D. Bowers shows that it is clearly not the first. From early athletes who used rat poison and heroin to fight fatigue to modern Olympians who perform under the ever-present shadow of high tech hormones, stimulants and steroids, this editorial lays out both the history and the science behind athletic "doping" scandals. Bowers ...

Highlights In the largest study of its kind, a variant within the multidrug resistance 1 (MDR-1) gene in kidney transplant donors was linked to a 69% increased risk for long-term failure of transplanted organs. This variant affects the expression of the protein that the MDR-1 gene encodes, which pumps drugs out of cells. (Immunosuppressant drugs are critical for preventing organ rejection but are also toxic to the kidneys.) Washington, DC (October 11, 2012) — A single genetic variant in kidney donors' cells may help determine whether their transplanted organs will survive ...

Boston, MA -- New research that combines cell phone data from 15 million people in Kenya with detailed information on the regional incidence of malaria has revealed, on the largest scale so far, how human travel patterns contribute to the disease's spread. The findings from researchers at Harvard School of Public Health (HSPH) and seven other institutions indicate that malaria, in large part, emanates from Kenya's Lake Victoria region and spreads east, chiefly toward the capital, Nairobi. The study appears in the October 12, 2012 issue of the journal Science. "This ...

COLUMBUS, Ohio – A group of researchers have proposed creating a new web-based data network to help researchers and policymakers worldwide turn existing knowledge into real-world applications and technologies and improve science and innovation policy. Researchers around the world have created datasets that, if interlinked with other datasets and made more broadly available could provide the needed foundation for policy and decision makers. But these datasets are spread across countries, scientific disciplines and data providers, and appear in a variety of inconsistent ...

MADISON — Scientists have identified three neighboring genes that make soybeans resistant to the most damaging disease of soybean. The genes exist side-by-side on a stretch of chromosome, but only give resistance when that stretch is duplicated several times in the plant. "Soybean cyst nematode is the most important disease of soybean, according to yield loss, worldwide, year after year," says senior author Andrew Bent, professor of plant pathology at University of Wisconsin-Madison. "As we try to feed a world that is going from 6 billion toward 9 billion people, soybean ...

Sophia Antipolis, 12 October 2012: Urgent actions including smoking bans in public places, salt restrictions and improved blood pressure control are needed to fight rising cardiovascular disease in China. Half of male physicians in China smoke and they can lead the way to healthy lifestyles by kicking the habit. Cardiovascular disease is the top cause of death in China and causes more than 40% of all deaths. "Every year three million Chinese people die from cardiovascular disease and every 10 seconds there is one death from CVD in China," said Professor Dayi Hu, chief ...

The relatively new field in microbiology that focuses on quorum sensing has been making strides in understanding how bacteria communicate and cooperate. Quorum sensing describes the bacterial communication between cells that allows them to recognize and react to the size of their surrounding cell population. While a cell's output of extracellular products, or "public goods," is dependent on the size of its surrounding population, scientists have discovered that quorum sensing, a type of bacterial communication, controls when cells release these public goods into their environments. ...

Scientists at Scripps Institution of Oceanography at UC San Diego have used 20 years of satellite data to reveal a geological oddity unlike any seen on Earth. At the border of Argentina, Bolivia and Chile sits the Altiplano-Puna plateau in the central Andes region, home to the largest active magma body in Earth's continental crust and known for a long history of massive volcanic eruptions. A study led by Yuri Fialko of Scripps and Jill Pearse of the Alberta Geological Survey has revealed that magma is forming a big blob in the middle of the crust, pushing up the earth's ...

October 12, 2012 – The human mouth is home to a teeming community of microbes, yet still relatively little is known about what determines the specific types of microorganisms that live there. Is it your genes that decide who lives in the microbial village, or is it your environment? In a study published online in Genome Research (www.genome.org), researchers have shown that environment plays a much larger role in determining oral microbiota than expected, a finding that sheds new light on a major factor in oral health. Our oral microbiome begins to take shape as soon ...

(Edmonton) A meteorite that landed in the Moroccan desert 14 months ago is providing more information about Mars, the planet where it originated. University of Alberta researcher Chris Herd helped in the study of the Tissint meteorite, in which traces of Mars' unique atmosphere are trapped. "Our team matched traces of gases found inside the Tissint meteorite with samples of Mars' atmosphere collected in 1976 by Viking, NASA's Mars lander mission," said Herd. Herd explained that 600 million years ago the meteorite started out as a fairly typical volcanic rock on the surface ...

Fly eyes have the fastest visual responses in the animal kingdom, but how they achieve this has long been an enigma. A new study shows that their rapid vision may be a result of their photoreceptors - specialised cells found in the retina - physically contracting in response to light. The mechanical force then generates electrical responses that are sent to the brain much faster than, for example, in our own eyes, where responses are generated using traditional chemical messengers. The study was published today, 12 October, in the journal Science. It had been thought ...

At very low temperatures, close to absolute zero, chemical reactions may proceed at a much higher rate than classical chemistry says they should – because in this extreme chill, quantum effects enter the picture. A Weizmann Institute team has now confirmed this experimentally; their results would not only provide insight into processes in the intriguing quantum world in which particles act as waves, it might explain how chemical reactions occur in the vast frigid regions of interstellar space. Long-standing predictions are that quantum effects should allow the formation ...

VALHALLA, October 11, 2012—A New York Medical College developmental biologist whose life's work has supported the theory of evolution has developed a concept that dramatically alters one of its basic assumptions—that survival is based on a change's functional advantage if it is to persist. Stuart A. Newman, Ph.D., professor of cell biology and anatomy, offers an alternative model in proposing that the origination of the structural motifs of animal form were actually predictable and relatively sudden, with abrupt morphological transformations favored during the early period ...

TORONTO, ON – Psychologists at the University of Toronto and the Georgia Institute of Technology – commonly known as Georgia Tech – have shown that an individual's inability to recognize once-familiar faces and objects may have as much to do with difficulty perceiving their distinct features as it does with the capacity to recall from memory. A study published in the October issue of Hippocampus suggests that memory impairments for people diagnosed with early stage Alzheimer's disease may in part be due to problems with determining the differences between similar objects. ...

WESTMINSTER, CO (October 10, 2012)—One of life's certainties is that everyone ages. However, it's also certain that not everyone ages at the same rate. According to recent research being presented this week, the cardiovascular system of people with type 2 diabetes shows signs of aging significantly earlier than those without the disease. However, exercise can help to slow down this premature aging, bringing the aging of type 2 diabetes patients' cardiovascular systems closer to that of people without the disease, says researcher Amy Huebschmann of the University of Colorado ...

WESTMINSTER, CO (October 10, 2012)—Researchers may soon be able to add yet another item to the list of exercise's well-documented health benefits: A preliminary study suggests that when cancer survivors exercise for several weeks after they finish chemotherapy, their immune systems remodel themselves to become more effective, potentially fending off future incidences of cancer. The finding may help explain why exercise can significantly reduce the chances of secondary cancers in survivors or reduce the chances of cancer altogether in people who have never had the disease. Laura ...

Parents: Want to help ensure your children turn out to be happy and socially well adjusted? Bond with them when they are infants. That's the message from a study by the University of Iowa, which found that infants who have a close, intimate relationship with a parent are less likely to be troubled, aggressive or experience other emotional and behavioral problems when they reach school age. Surprisingly, the researchers found that a young child needs to feel particularly secure with only one parent to reap the benefits of stable emotions and behavior, and that being attached ...

WESTMINSTER, CO (October 10, 2012)—Time spent in the drudgery of strenuous exercise is a well-documented turn-off for many people who want to get in better shape. In a new study, researchers show that exercisers can burn as many as 200 extra calories in as little as 2.5 minutes of concentrated effort a day—as long as they intersperse longer periods of easy recovery in a practice known as sprint interval training. The finding could make exercise more manageable for would-be fitness buffs by cramming truly intense efforts into as little as 25 minutes. Kyle Sevits, Garrett ...

Space debris came into focus last week at the International Astronautical Congress in Naples, Italy. Envisat, ESA's largest Earth observation satellite, ended its mission last spring and was a subject of major interest in the Space Debris and Legal session. Envisat was planned and designed in 1987, a time when space debris was not considered to be a serious problem and before the existence of mitigation guidelines, established by the UN in 2007 and adopted the next year by ESA for all of its projects. Only later, during the post-launch operational phase, did Envisat's ...

BOSTON – In recent years investigators have discovered that breast tumors are influenced by more than just the cancer cells within them. A variety of noncancerous cells, which in many cases constitute the majority of the tumor mass, form what is known as the "tumor microenvironment." This sea of noncancerous cells and the products they deposit appear to play key roles in tumor pathogenesis. Among the key accomplices in the tumor microenvironment are mesenchymal stem cells (MSCs), a group of adult progenitor cells which have been shown to help breast cancers maneuver and ...

WESTMINSTER, CO (October 10, 2012)—Numerous studies have shown that female athletes are more likely to get knee injuries, especially anterior cruciate ligament (ACL) tears and chronic pain, than their male counterparts. While previous research has focused on biomechanical differences as the main source of these problems, a new study suggests another distinction that could play a role: changes across the menstrual cycle in nerves that control muscle activity. The finding may eventually lead to new ways to prevent knee problems in female athletes. Matthew Tenan, Yi-Ling ...

KNOXVILLE—Children who play on playgrounds that incorporate natural elements like logs and flowers tend to be more active than those who play on traditional playgrounds with metal and brightly colored equipment, according to a recent study from the University of Tennessee, Knoxville. They also appear to use their imagination more, according to the report. The study, which examined changes in physical activity levels and patterns in young children exposed to both traditional and natural playgrounds, is among the first of its kind in the United States, according to Dawn ...

Despite homeland security improvements since September 11, 2001, subway and rail commuters face higher risks of falling victim to terrorists and mass violence than frequent flyers or those engaged in virtually any other activity. And while successful criminal and terrorist acts against aviation have fallen sharply, those against subways and commuter trains have surged. These are among the findings of a new study by Arnold Barnett, George Eastman Professor of Management Science at MIT's Sloan School of Management, who will deliver a presentation titled "Has Terror Gone to ...
