An interdisciplinary team of researchers at Vanderbilt University have developed a way to combine the photosynthetic protein that converts light into electrochemical energy in spinach with silicon, the material used in solar cells, in a fashion that produces substantially more electrical current than has been reported by previous "biohybrid" solar cells. The research was reported online on Sep. 4 in the journal Advanced Materials and Vanderbilt has applied for a patent on the combination. "This combination produces current levels almost 1,000 times higher than we were ...

LEXINGTON, Ky. (Sept. 4, 2012) — A new study by University of Kentucky researchers shows promise for developing ultrastable RNA nanoparticles that may help treat cancer and viral infections by regulating cell function and binding to cancers without harming surrounding tissue. The study, published in Nano Today, was carried out in the laboratory of Peixuan Guo, the William S. Farish Endowed Chair in Nanobiotechnology at the UK Markey Cancer Center, in collaboration with Dr. Mark Evers, director of the UK Markey Cancer Center. The study uses RNA (ribonucleic acid) as ...

Vienna, Austria: Sleep apnoea severity has been associated with increased cancer mortality in a new study. The research, which will be presented today (Tuesday 4 September 2012) at the European Respiratory Society's (ERS) Annual Congress in Vienna, adds to evidence presented earlier this year highlighting a link between severe sleep apnoea and cancer. Two further studies presented at the ERS Congress, also show evidence suggesting an increase in cancer incidence among sleep apnoea patients and an association between the spread of cancer and sleep apnoea. In the first ...

Vienna, Austria: The prevalence of smoking in Christchurch, New Zealand, increased following the 2010 earthquake, according to a new study. The results of the study will be presented today (4 September 2012) at the European Respiratory Society's Annual Congress in Vienna. The 7.1-magnitude Christchurch earthquake, and subsequent aftershocks, have caused a huge amount of damage and dramatically changed the social, working and living conditions for residents in the city. To investigate the effects of the disaster on smoking levels, researchers from the Canterbury ...

Vienna, Austria: Exposure to volcanic ash can increase respiratory symptoms such as an extreme cough, or phlegm, according to a new study. The research, which will be presented today (4 September 2012) at the European Respiratory Society's Annual Congress in Vienna, investigated the effects of living close to the Icelandic Volcano, Eyjafjallajökull. Eyjafjallajökull erupted in April 2010 and created a huge ash cloud which spread across Europe, causing widespread disruption to air travel on the continent. Researchers from the University of Iceland have now examined ...

EAST LANSING, Mich. — Witch hunts are common and sometimes deadly in the tea plantations of Jalpaiguri, India. But a surprising source – small groups of women who meet through a government loan program – has achieved some success in preventing the longstanding practice, a Michigan State University sociologist found. Soma Chaudhuri spent seven months studying witch hunts in her native India and discovered that the economic self-help groups have made it part of their agenda to defend their fellow plantation workers against the hunts. "It's a grassroots movement and it's ...

SEATTLE – A team of scientists led by a bone marrow transplant researcher at Fred Hutchinson Cancer Research Center has shed new light on why most bone marrow transplant patients who receive tissue-matched cells from unrelated donors still suffer acute graft-versus-host disease (GVHD). The answer appears to lie in the discovery of previously undetected genetic differences in the DNA of patients and unrelated marrow donors. The laboratory-based study findings by Effie Petersdorf, M.D., and colleagues soon will be translated to the clinic when a Hutchinson Center transplant ...

Los Angeles, CA (September 4, 2012) While the effects of sexualized media on young women has long been debated, a new study finds that women who read sex-related magazine articles from popular women's magazines like Cosmopolitan are less likely to view premarital sex as a risky behavior. Additionally, the women who are exposed to these articles are more supportive of sexual behavior that both empowers women and prioritizes their own sexual pleasure. This study was published in a recent article from Psychology of Women Quarterly (published by SAGE). Study authors Janna ...

Might it one day be possible to transmit electricity from an offshore wind turbine to land-based users without any loss of current? Materials known as "high temperature" superconductors (even though they must be maintained at -140°C!), which can conduct electricity without any losses, were supposed to make this dream a reality. But over the past twenty-five years, scientists have not been able to make any progress in this area. Research being done in EPFL's Laboratory for Quantum Magnetism (LQM) could change that. Their study of magnetism at extremely small scales could ...

Released en masse, sterile Mexican fruit flies can undermine a wild population of the fruit-damaging pests so that fewer applications of insecticide are needed. But the irradiation used to sterilize the flies weakens them, hindering their ability to outcompete wild-type males for female mates. Now, U.S. Department of Agriculture (USDA) and collaborating scientists have devised a hormone therapy for making sterile flies "more macho," improving their chances of mating with female flies before their wild rivals do. Peter Teal, a chemist with USDA's Agricultural Research ...

Researchers have discovered two gene variants that raise the risk of the pediatric cancer neuroblastoma. Using automated technology to perform genome-wide association studies on DNA from thousands of subjects, the study broadens understanding of how gene changes may make a child susceptible to this early childhood cancer, as well as causing a tumor to progress. "We discovered common variants in the HACE1 and LIN28B genes that increase the risk of developing neuroblastoma. For LIN28B, these variants also appear to contribute to the tumor's progression once it forms," said ...

Coastline recession The anticipated rise in sea levels due to climate change will result in coastlines receding worldwide through erosion. This is a known phenomenon that can in principle be calculated and predicted based on a given sea-level rise, by means of the so-called Bruun effect. However, things are a little more complicated when it comes to coastlines in the vicinity of inlets, such as river mouths, lagoons and estuaries. These places are affected by other factors, such as changes in rainfall due to climate change, and certain compensating effects (basin infilling). Accurate ...

A lone rooster sees a lot of all the hens in the flock, but the hen with the largest comb gets a bigger dose of sperm - and thus more chicks. This sounds natural, but behind all this is humanity's hunger for eggs. For thousands of years, people have tinkered with the development of domestic chickens. Through selective breeding for a few characteristics such as large muscle mass and increased egg-laying, we have at the same time caused numerous other radical changes in appearance and behaviour. A research group at Linköping University in Sweden has now shown how the size ...

A new fungal species, called 'Hebelomagriseopruinatum', has now officially been included in the list of species. The fungus, whose name can be translated into 'the grey-dewy tear leaf', was discovered on Zealand in Denmark during a mushroom-hunting tour headed by postdoc Jacob Heilman-Clausen from the University of Copenhagen. During a mushroom-hunting excursion in 2009, postdoc Jacob Heilman-Clausen from the Center for Macroecology, Evolution and Climate at the Department of Biology, University of Copenhagen, was handed a very interesting looking fungus. Following ...

Inexperienced psychiatrists are less likely than their veteran peers to accurately predict violence by their patients, but a simple assessment checklist might help bridge that accuracy gap, according to new research from the University of Michigan. Led by psychiatrist Alan Teo, M.D., a Robert Wood Johnson Foundation Clinical Scholar of the University of Michigan, researchers examined how accurate psychiatrists were at predicting assaults by acutely ill patients admitted to psychiatric units. Their results found that inexperienced psychiatric resident doctors did no ...

A large meta-analysis conducted by researchers at Moffitt Cancer Center has concluded that breast cancer patients treated with chemotherapy are at risk for mild cognitive deficits after treatment. The meta-analysis, or analytic review of previously published studies, found that study participants on average had mild impairments in verbal abilities (such as difficulty choosing words) and visuospatial abilities (such as getting lost more easily). The study noted that cognitive functioning varies across survivors, with some reporting no impairments and others reporting more ...

1. A*STAR scientists have identified a biomarker of the most lethal form of brain tumours in adults- glioblastoma multiforme. The scientists found that by targeting this biomarker and depleting it with a potential drug, they were able to prevent the progression and relapse of the brain tumour. 2. This research was conducted by scientists at A*STAR's Institute of Medical Biology led by Dr Prabha Sampath, Principal Investigator, in collaboration with A*STAR's Bioinformatics Institute (BII), and clinical collaborators from Medical University of Graz, Austria, and National ...

HOUSTON -- (Sept. 4, 2012) -- In the face of mounting evidence that cancer cells communicate, cooperate and even engage in collective decision-making, biophysicists and cancer researchers at Rice University, Tel Aviv University and Johns Hopkins University are suggesting a new strategy for outsmarting cancer through its own social intelligence. "We need to get beyond the notion that cancer is a random collection of cells running amok," said Herbert Levine, co-director of Rice's Center for Theoretical Biological Physics (CTBP) and co-author of the cover article in this ...

HOUSTON – (Sept. 4, 2012) – Like tiny ships finding port in a storm, carbon atoms dock with the greater island of graphene in a predictable manner. But until recent research by scientists at Rice University, nobody had the tools to make that kind of prediction. Electric current shoots straight across a sheet of defect-free graphene with almost no resistance, a feature that makes the material highly attractive to engineers who would use it in things like touchscreens and other electronics, said Rice theoretical physicist Boris Yakobson. He is co-author of a new paper about ...

Almost three quarters of disposed electrical household appliances in Spain are processed out of the Integrated Waste Management System (SIG). A study at the University of Salamanca exposes how many manufacturers are not registered in the established waste management system and avoid payment. According to the European directive on waste electrical and electronic equipment, manufacturers of such products should recycle the waste they generate during their activity until reaching an annual level of 4 kg per inhabitant. However, in Spain the majority of unused equipment is ...

The governance of Canada's massive Mackenzie River Basin holds enormous national but also global importance due to the watershed's impact on the Arctic Ocean, international migratory birds and climate stability, say experts convening a special forum on the topic. "Relevant parties in western Canada have recognized the need for a multi-party transboundary agreement that will govern land and water management in the Mackenzie River watershed. Successful collaboration will effectively determine the management regime for a watershed covering 1.8 million square kilometers or ...

1. No Nutritional or Safety Differences Between Organic and Conventional Foods There is generally no difference in nutritional value or risk for bacterial contamination between organic and conventional foods, according to a new study being published in Annals of Internal Medicine, the flagship journal of the American College of Physicians (ACP). While the consumption of organic fruits and vegetables reduced exposure to any detectable pesticide residues by 30 percent, pesticide levels were generally within the allowable limits for safety. Researchers conducted a systematic ...

MINNEAPOLIS – People whose blood sugar is on the high end of the normal range may be at greater risk of brain shrinkage that occurs with aging and diseases such as dementia, according to new research published in the September 4, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology. "Numerous studies have shown a link between type 2 diabetes and brain shrinkage and dementia, but we haven't known much about whether people with blood sugar on the high end of normal experience these same effects," said study author Nicolas Cherbuin, ...

STANFORD, Calif. — You're in the supermarket eyeing a basket of sweet, juicy plums. You reach for the conventionally grown stone fruit, then decide to spring the extra $1/pound for its organic cousin. You figure you've just made the healthier decision by choosing the organic product — but new findings from Stanford University cast some doubt on your thinking. "There isn't much difference between organic and conventional foods, if you're an adult and making a decision based solely on your health," said Dena Bravata, MD, MS, the senior author of a paper comparing the nutrition ...
