June 8, 2011 — (Bronx, NY) — Researchers at Albert Einstein College of Medicine of Yeshiva University have identified a key player in the spread of breast cancer. The findings, published today in the online edition of Nature, identify a critical molecule that helps cancer spread beyond the primary tumor. The research highlights a potential new strategy against metastatic disease. The study's senior author is Jeffrey Pollard, Ph.D., professor of developmental and molecular biology and of obstetrics & gynecology and women's health at Einstein. He also holds the Louis Goldstein ...

This week it was announced that a dark matter detector about 700 meters below the ground in a Minnesota mine has recorded a seasonal modulation in staggeringly faint electrical pulses. One possible reason: this could be the result of dark matter particles called WIMPs that envelope the Milky Way galaxy and collide with atoms in the detector's germanium crystal. This seems possible because the results are consistent with modulation in signals first recorded more than a decade ago by the DArk MAtter/Large sodium Iodide Bulk for RAre processes (DAMA/LIBRA) experiment at ...

Birds and people both enjoy urban woodlands that have been cleared to just the right degree. This is the conclusion of scientists at the University of Gothenburg who have carried out large-scale field experiments in urban woodlands in south-western Sweden. "Three out of four people want a mixture of open and untouched forest for rambling. At the same time, we can see that birds do well and continue to nest in woodlands where less than 50% has been cleared", says Erik Heyman of the Department of Plant and Environmental Sciences at the University of Gothenburg. The natural ...

Named "The Height of Luxury" by The Washington Post, Turnberry Tower was the Washington, DC-area's top-selling luxury condominium project in 2010. The ultra-luxury residential tower is breaking records again in 2011, with $70 million in new sales to date this year -- at an average price of over $1.3 million. This places Turnberry Vice President of Sales and Marketing, Dan Riordan, with a spectacular view of Turnberry Tower's future as the area's tallest residential condominium project. The 26-story, sapphire-blue spire is a beacon adjacent to the Key Bridge, offering ...

The swine flu outbreak of winter 2009-2010 was much more widespread than was previously realised, research suggests. Blood samples taken from Scottish adults in March last year at the end of the H1N1 flu season showed that almost half were carrying antibodies to the virus. Most of the 44 per cent who tested positive had contracted swine flu, although some had acquired immunity from a previous bout of flu, or had been vaccinated. The research, led by the University of Edinburgh, shows that many cases of swine flu went unreported. Only 100,000 people consulted their ...

It looks like a credit card…it slips into a wallet or purse…but it could mean the difference between life and death in a medical emergency. The MyCare Card stores personal medical data (e.g. information on existing medical conditions, allergies and medication being taken) and plugs into a laptop's USB port, enabling the data to be accessed in just a few moments. It is the first device of its type to have been trialled in the UK. This working prototype has been developed by City University London and Coventry University, with funding from the Engineering and Physical ...

The study, published yesterday in the journal Ecology Letters, analyzed the species richness and the structure of their communities throughout the different regions of the European territory from the Ural Mountains to the Iberian Peninsula. The selection of this family of insects was motivated by their high dispersal ability and because their food sources (mainly cattle and sheep dung) are present throughout the continent. Research by the Spanish National Research Council reveals that the large impacts occurred during the last ice age maintain their effects on the current ...

When a person has a family history of cancer, their worry about developing the disease may lead to them refusing to have preventive tests. Advice from genetic counselling units reduces their anxiety but, until now, nobody knew how much. Now, a scientific team has validated the 'Escala de Preocupación por el Cáncer - EPC' (equivalent of the Cancer Worry Scale), the first of its kind in the Spanish language, in order to evaluate it. "Excessive concern about cancer can result in two kinds of behaviour. Some people undergo excessive and unnecessary diagnostic tests, while ...

The German National Academy of Sciences Leopoldina has submitted an ad-hoc statement on energy research to Prof. Annette Schavan, the German Federal Minister of Education and Research. Against the backdrop of the events in Fukushima, the statement contains twelve key declarations that mainly address research-policy issues connected to the restructuring of Germany's energy system. The German National Academy of Sciences Leopoldina compiled the statement, entitled "Energiepolitische und forschungspolitische Empfehlungen nach den Ereignissen in Fukushima" (Energy- and research-policy ...

PROVIDENCE, R.I. – Researchers from Hasbro Children's Hospital in Providence, R.I., report that medical management may be preferred over surgery for children with orbital cellulitis, an acute infection of the tissues surrounding the eye. They have determined the criteria for surgical intervention should be dependent upon the size of a subperiosteal abscess (SPA). The research is published in the journal Ophthalmic Plastic & Reconstructive Surgery and is now available online in advance of print. Orbital cellulitis is most often the result of bacteria from a sinus infection, ...

As millions of acres of farmland in the U.S. Midwest and South recover from Mississippi River flooding, scientists report that river flooding can increase levels of potentially harmful flame retardants in farm soils. But the higher levels apparently do not find their way into the milk produced by cows that graze on these lands, according to a study in the ACS journal Environmental Science & Technology. Iain Lake and colleagues note that the flame retardants, called PBDEs, are found in a variety of household products including furniture upholstery, textiles, cars, plastics, ...

Antioxidants are popular anti-aging ingredients in skin creams, and now scientists are reporting a new source of these healthful substances — leaf buds of poplar trees. Their study appears in the ACS' Journal of Agricultural and Food Chemistry. Xavier Vitrac and colleagues note that there's a long history of using poplar buds to treat various health problems, such as colds, sinusitis, sunburn and arthritis. A substance found in beehives that is made from poplar buds (called propolis) also appears to have similar disease-fighting benefits. Propolis' effects seem to be ...

Medical scientists now have "clear" evidence that the damaged cartilage tissue in osteoarthritis and other painful joint disorders can be encouraged to regrow and regenerate, and are developing tissue engineering technology that could help millions of patients with those disorders. That's the conclusion of a new analysis of almost 100 scientific studies on the topic, published in ACS's journal Molecular Pharmaceutics. Tong Cao, Wei Seong Toh and colleagues point out that damage to so-called articular cartilage — the smooth, white, rubbery tissue that covers and cushions ...

Despite years of scientific studies, reports, lawsuits, congressional inquiries, claims and counterclaims, the question of whether bisphenol A (BPA) poses health threats to people lacks a definitive answer, according to a package of articles on the controversial substance in the current edition of Chemical & Engineering News (C&EN), ACS's weekly newsmagazine. In the articles, C&EN Senior Correspondent Stephen K. Ritter explains that BPA has been used in an array of consumer goods since the 1950s. Today it is a mainstay ingredient in hard plastics in some reusable drink ...

COLLEGE PARK, MD (June 8, 2011) -- When the current financial crisis hit, the failure of traditional economic doctrines to provide any sort of early warning shocked not only financial experts worldwide, but also governments and the general public, and we all began to question the effectiveness and validity of those doctrines. A research team based in Israel decided to investigate what went awry, searching for order in an apparently random system. They report their findings in the American Institute of Physics' journal AIP Advances. The novelty of their study is the ...

The goal of the brochure is to showcase Patrick's holistic approach to shooting food photography by breaking down the food industry into its four component parts and illustrating them with photography. Each dish in the piece has a unique story all its own, and Patrick uses his skills with the camera to bring every step in the food preparation process ...

More and more pathogens are becoming immune to antibiotics. Some bacteria can no longer be combated. The World Health Organization WHO is warning about resistance to drugs which were once so potent. The WHO's director-general Margaret Chan has pointed out that if measures are not taken quickly, it may soon not be possible to treat many frequently occurring infections. Figures released by the WHO show that in 2010 nearly half-a-million people were infected with a strain of tuberculosis which is resistant to many antibiotics – one third of those infected died. The Organization ...

The plane takes off from Munich in bright weather, temperature 10 degrees Celsius, and lands in Anchorage, Alaska, in driving snow, temperature minus 15. Parked on the airfield overnight, the aircraft takes off the next morning at a freezing minus 25 degrees, heading for Dubai, where the weather is a sunny 32 degrees. The temperature on the outside of the fuselage is over 80 degrees. The rapid changes in temperature pose a challenge for the technical systems and materials. How can it be ensured that the onboard equipment will function in all circumstances? Scientists at ...

Researchers identify gender disparities in the appropriate use of nuclear stress tests More women than men are unnecessarily referred for nuclear stress tests Majority of inappropriate studies ordered by primary care physicians PROVIDENCE, R.I. – New research from cardiologists at Rhode Island and The Miriam hospitals suggests a possible gender disparity in how patients are referred for nuclear stress tests, an imaging technique that measures blood flow to the heart muscle both at rest and during periods of stress, such as exercise. According to the study, published ...

June 8, 2011 – Researchers at Children's Hospital Boston have found a marker called ABCB5 that both tags a small proportion of cells within colorectal cancers and fuels resistance in those cells to standard treatments. The results indicate that eliminating ABCB5-expressing cells is crucial for successful colorectal cancer treatment, while adding to the growing body of evidence for a theory of cancer growth called the cancer stem cell hypothesis. An international team led by Brian J. Wilson, PhD, Tobias Schatton, PhD, and Markus Frank, MD, of the Transplantation Research ...

A new study from biology researchers at Baylor University and the University of Maryland-Baltimore has found that there are consistent and widespread declines in stream biodiversity at lower levels of urban development more damaging than what was previously believed. The study found that aquatic life actually shows significant loss of biodiversity with less than two percent of developed land in a watershed. This is much less that what a decade-old analysis widely cited by environmental policymakers suggests that it takes up to 15 percent of solid surfaces like roads ...

STANFORD, Calif. — New research has shown that children's risk for learning and behavior problems and obesity rises in correlation to their level of trauma exposure, says the psychiatrist at the Stanford University School of Medicine and Lucile Packard Children's Hospital who oversaw the study. The findings could encourage physicians to consider diagnosing post-traumatic stress disorder rather than attention deficit/hyperactivity disorder, which has similar symptoms to PTSD but very different treatment. The study examined children living in a violent, low-income neighborhood ...

Almost universally, red means stop. Red means danger. Red means hot. And analyzing the results in the 2004 Olympics, researchers have found that red also means dominance. Athletes wearing red prevailed more often than those wearing blue, especially in hand-to-hand sports like wrestling. Why? Is it random? Is it cultural? Or does it have evolutionary roots? A new study of male rhesus macaques strongly suggests it's evolution. "The similarity of our results with those in humans suggests that avoiding red or acting submissively in its presence may stem from an inherited ...

Researchers from NOAA have discovered a potent and highly-debilitating toxin in the endangered Hawaiian monk seal, a first-of-its-kind chemical finding that is now prompting investigations of other marine mammals in the state. The toxin, ciguatoxin, is produced by marine algae common on coral reefs, and accumulates in fish species that are consumed by humans. Ciguatera, the human disease caused by ciguatoxin, affects thousands of people every year worldwide and comes in the form of acute gastrointestinal and neurological illness with symptoms resembling chronic fatigue ...
