Is there a link between the risk of breast cancer and the working environment? A study published in BioMed Central's open access journal Environmental Health provides further evidence on this previously neglected research topic, confirming that certain occupations do pose a higher risk of breast cancer than others, particularly those that expose the worker to potential carcinogens and endocrine disrupters. Breast cancer is the most frequent cancer diagnosis among women in industrialized countries, and North American rates are among the highest in the world. Endocrine-disrupting ...

PITTSBURGH, Nov. 19, 2012 – More than half of all retired people aged 65 and over report sleeping at least 7.5 hours per night, and between the hours of 11 p.m. and 7:30 a.m., contrary to commonly held assumptions that most elderly go to bed early and have trouble sleeping through the night, according to a study by researchers at the University of Pittsburgh's Sleep and Chronobiology Center (SCC) and University Center for Social and Urban Research (UCSUR). This new study, supported by a grant from the National Institute on Aging, was conducted over five years and is among ...

Mosquitos have the remarkable ability to fly in clear skies as well as in rain, shrugging off impacts from raindrops more than 50 times their body mass. But just like modern aircraft, mosquitos also are grounded when the fog thickens. Researchers from the Georgia Institute of Technology present their findings at the 65th meeting of the American Physical Society's (APS) Division of Fluid Dynamics, Nov. 18 - 20, in San Diego, Calif. "Raindrop and fog impacts affect mosquitoes quite differently," said Georgia Tech researcher Andrew Dickerson. "From a mosquito's perspective, ...

A new approach to invisibility cloaking may one day be used at sea to shield floating objects – such as oil rigs and ships – from rough waves. Unlike most other cloaking techniques that rely on transformation optics, this one is based on the influence of the ocean floor's topography on the various "layers" of ocean water. At the American Physical Society's (APS) Division of Fluid Dynamics (DFD) meeting, being held November 18-20, 2012, in San Diego, Calif., Reza Alam, assistant professor of mechanical engineering at the University of California, Berkeley, will describe ...

Owls have the uncanny ability to fly silently, relying on specialized plumage to reduce noise so they can hunt in acoustic stealth. Researchers from the University of Cambridge, England, are studying the owl's wing structure to better understand how it mitigates noise so they can apply that information to the design of conventional aircraft. They present their findings at the American Physical Society's (APS) Division of Fluid Dynamics meeting, held Nov. 18 – 20, in San Diego, Calif. "Many owl species have developed specialized plumage to effectively eliminate the aerodynamic ...

Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, researchers at Caltech led by Chiara Daraio, a professor of aeronautics and applied physics, developed a nonlinear acoustic lens that can focus high-amplitude pressure pulses into compact "sound bullets." In that initial work, the scientists demonstrated how sound bullets form in solids. Now, they have done themselves one better, creating a device that can form and control those bullets ...

November 19, 2012, Shenzhen, China – An international research team led by Nanjing Agricultural University and BGI, has completed the first genomic sequence of pear by an approach using the combination of BAC-by-BAC strategy and next-gen sequencing. The pear genome not only provides an invaluable new resource for breeding improvement of this important crop, but also sheds new light on the genome evolution and other genome-wide comparative studies. The results were published online in Genome Research. As one of the oldest fruit crops, pear has more than 3,000 years of cultivation ...

It is hypothesized that cocoons attached to any material were transported by air, eg by NATO aircraft, after which the moths found their favourite hostplant commonly planted. The finding of an unknown small moth by Dutch amateur moth hunter Hans Huisman in his backyard lead to the discovery that the American Oak skeletonizer (Bucculatrix ainsliella) is invading North West Europe on planted Northern Red oaks (Quercus rubra), a North American tree. "The finding is unusual", says Erik J van Nieukerken of Naturalis Biodiversity Center (Leiden, Netherlands), "because until ...

These are some of the results of a report for the World Bank, conducted by the Potsdam Institute for Climate Impact Research (PIK) and Climate Analytics in Berlin. The poorest in the world are those that will be hit hardest, making development without climate policy almost impossible, the researchers conclude. "The planetary machinery tends to be jumpy, this is to respond disproportionately to disruptions that come with the manmade greenhouse effect," PIK's director Hans Joachim Schellnhuber points out. "If we venture far beyond the 2-degree guardrail, towards 4 degrees, ...

VIB researchers from UGent and Vrije Universiteit Brussel , together with a team of the firm Oxyrane have developed a new technology that can lead to a more efficient and possibly also cheaper therapy for diseases such as Pompe disease. Oxyrane will now start developing a clinical program for this therapy in Pompe disease. Nico Callewaert (VIB-UGent): "By combining natural processes and proteins of two microbes and a plant we have improved the technology to produce enzymes that patients with metabolic disorders can't produce themselves. We played with the sugar structures ...

The answer is yes. Finnish researchers have developed a triumphant solution for predicting responses of breast cancer cells to a set of cancer drugs. The prediction is based on the genomic profiles of the cancer cells. Harnessing genomic profiles of cells in choosing the best treatment is considered the holy grail of personalised medicine. The team led by Professor Samuel Kaski from Helsinki institute of Information Technology (HIIT), a joint research centre of Aalto University and University of Helsinki, Finland, presented its winning solution at the DREAM 2012 conference ...

Male tree frogs like to 'see what they're getting' when they select females for mating, according to a new study by Dr. Michael Reichert from the University of Wisconsin-Milwaukee in the US. His work, which is one of the first to test the importance of vision on male mating behaviors in a nocturnal anuran (frog or toad), is published online in Springer's journal Behavioral Ecology and Sociobiology. Animals display a number of courtship behaviors and are able to modulate these behaviors depending on the likelihood of mating. For example, displaying males may increase the ...

A new study from Karolinska Institutet in Sweden shows, that a technique for measuring bone density called digital X-ray radiogrammetry (or DXR) used on standard hand radiographs can help to identify patients with a higher risk of hip fracture. The researchers believe that DXR, which is fully comparable with other, more costly methods, can be used preventively to identify people in the risk zone for osteoporosis – a disease estimated to effect some 200 million women worldwide. Each year, approximately 1.7 million hip fractures occur worldwide (about 18,000 only in Sweden), ...

Scientists at the University of Southampton are pioneering a technique to predict when an ecosystem is likely to collapse, which may also have potential for foretelling crises in agriculture, fisheries or even social systems. The researchers have applied a mathematical model to a real world situation, the environmental collapse of a lake in China, to help prove a theory which suggests an ecosystem 'flickers', or fluctuates dramatically between healthy and unhealthy states, shortly before its eventual collapse. Head of Geography at Southampton, Professor John Dearing ...

A large-scale international study involving French researchers from the Inserm-Institut Pasteur Lille-Université Lille Nord de France "Public health and molecular epidemiology of ageing-related diseases" joint research unit led by Philippe Amouyel, has just discovered a gene for susceptibility to a rare disease that causes susceptibility to a common one, Alzheimer's disease, providing evidence of the heterogeneous aetiology of Alzheimer's disease. This whole-exome sequencing approach is explained in detail in The New England Journal of Medicine dated 14 November 2012. ...

ANN ARBOR, Mich. — Could the emergency room be a good place to spot undiagnosed eating disorders among teens, and help steer them to treatment? A new study from the University of Michigan suggests that could be the case. Researchers screened more than 940 teens and young adults aged 14 years to 20 years for eating disorders, as part of their visit to the U-M Emergency Department for any non-psychiatric reason. They found that 16 percent – more than one in every 6 – had indications of an eating disorder. Those that did were also much more likely to also show signs ...

U.S. Department of Agriculture (USDA) scientists are helping deployed American troops protect themselves against sand flies, which are major pests in Afghanistan, Africa and the Middle East. Sand flies are vectors of Leishmania parasites that cause leishmaniasis, a devastating disease for which there is no vaccine or medication. People who are bitten by infected sand flies do not know whether they have the disease until it becomes apparent three or four months later. Symptoms include permanent skin disfigurement and sometimes severe organ damage. At the Agricultural ...

A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts Institute of Technology (MIT) in Cambridge, is the first tool that can deliver precise points of light to a 3-D section of living brain tissue. The work is a step forward for a relatively new but promising technique that uses gene therapy to turn individual brain cells on and off with light. Scientists can use the new 3-D "light switch" to better understand how the ...

​For Immediate Release – November 19, 2012 (Toronto) Youth with mental illness are among the most vulnerable, but new research from the Centre for Addiction and Mental Health (CAMH) has found that less than half of Ontario youth aged 15 to 19 hospitalized with a psychiatric diagnosis received follow-up care with a primary care doctor or psychiatrist within a month after being discharged. "Timely aftercare is crucial in maintaining the health of youth with mental illness, and avoids future hospitalization, which is the most intensive, intrusive and expensive psychiatric ...

WASHINGTON, D.C. – Three organizations representing America's research universities today launched a website that aims to inform policymakers and the public of the impact that the upcoming budget sequester would have on federal funding for university research. The organizations – the Association of American Universities (AAU), the Association of Public and Land-grant Universities (APLU) and The Science Coalition (TSC) – urge Congressional leaders and the President to act quickly to develop a comprehensive, balanced solution to America's fiscal crisis that avoids steep cuts ...

Injured patients were less likely to die in the hospital if they had alcohol in their blood, according to a study from the University of Illinois at Chicago School of Public Health -- and the more alcohol, the more likely they were to survive. "This study is not encouraging people to drink," cautions UIC injury epidemiologist Lee Friedman, author of the study, which will be published in the December issue of the journal Alcohol and is now online. That's because alcohol intoxication -- even minor inebriation -- is associated with an increased risk of being injured, he ...
