A new breakthrough in solar technology means portable electronic devices such as e-book readers could soon be re-charged on the move in low light levels and partial shading. Scientists from the University of Warwick, in collaboration with spin-out company Molecular Solar, have created an organic solar cell that generates a sufficiently high voltage to recharge a lithium-ion battery directly, without the need to connect multiple individual cells in series. Modules of these high voltage cells perform well in different light conditions including partial shade making them ...

This press release is available in Spanish. To help increase the survival of newborn piglets, U.S. Department of Agriculture (USDA) scientists have developed a new method that predicts animals' mortality and nursing ability. Physiologist Jeffrey Vallet and his colleagues at the Agricultural Research Service (ARS) Roman L. Hruska U.S. Meat Animal Research Center (USMARC) in Clay Center, Neb., call the measuring technique the "immunocrit," which determines whether preweaning piglets receive adequate colostrum from the sow. ARS is USDA's principal intramural scientific research ...

Click here for more information. ESA's Huygens probe bounced, slid and wobbled its way to rest in the 10 seconds after touching down on Saturn's moon, Titan, in January 2005, a new analysis reveals. The findings provide novel insight into the nature of the moon's surface. Scientists reconstructed the ...

NEW YORK (October 11, 2012)— A new study by the Wildlife Conservation Society and James Cook University says that coral reefs in Aceh, Indonesia are benefiting from a decidedly low-tech, traditional management system that dates back to the 17th century. Known as "Panglima Laot" – the customary system focuses on social harmony and reducing conflict among communities over marine resources. According to the study, reefs benefitting from Panglima Laot contain as much eight time more fish and hard-coral cover due to mutually agreed upon gear restrictions especially prohibiting ...

The Automotive Recyclers Association (ARA) today announced its support of the National Highway Traffic Safety Administration's (NHTSA) efforts to warn consumers about those who would promote the sale and use of counterfeit air bags. ARA has long cautioned the automotive repair industry community and consumers about the dangers of using counterfeit air bags, as well as the alarming practice of omitting airbags altogether in repairs. In fact, in 2009, NHTSA reviewed fatal accidents in a 5 year period and found that airbags were missing in 18 percent of the crashed vehicles ...

MAYWOOD, Il. - When hospital patients have to be readmitted soon after discharge, hospitals look bad. And in addition to reflecting poorly on a hospital's quality of care, a high readmission rate also can result in reduced Medicare reimbursements, under provisions now taking effect under the 2010 health care law. But a study of spine surgery patients has found that the standard method used to calculate readmission rates is a misleading indicator of hospital quality. Loyola University Medical Center neurosurgeon Beejal Amin, MD, and colleagues found that 25 percent of ...

MINNEAPOLIS – New research reveals that stroke may be affecting people at a younger age. The study is published in the October 10, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology. "The reasons for this trend could be a rise in risk factors such as diabetes, obesity and high cholesterol," said study author Brett Kissela, MD, MS, with the University of Cincinnati College of Medicine in Ohio and a Fellow of the American Academy of Neurology. "Other factors, such as improved diagnosis through the increased use of MRI imaging may ...

Women who read negative news remember it better than men do, and have stronger stress responses in subsequent stress tests, according to new research published Oct 10 in the open access journal PLOS ONE by Sonia Lupien and colleagues from the University of Montreal, Canada. The researchers exposed groups of men and women to a succession of headlines drawn from recent newspaper articles. One group viewed only 'neutral' news, while the other group was shown news perceived as 'negative'. After reading the news, participants performed a standard psychological stress test. ...

A collection of fossil animals discovered off the coast of Florida suggests that present day deep-sea fauna like sea urchins, starfish and sea cucumbers may have evolved earlier than previously believed and survived periods of mass extinctions similar to those that wiped out the dinosaurs. The full results are published Oct. 10 in the open access journal PLOS ONE by Ben Thuy and colleagues from the University of Göttingen, Germany. Previously, researchers believed that these present-day animals evolved in the relatively recent past, following at least two periods of mass ...

Single fatherhood is a challenge many arachnids undertake, guarding eggs laid by females despite the costs to their own health and mating benefits, but the news may not be all bad for these dads. New research now shows that, in one species of spiders, males exclusively responsible for guarding eggs actually enjoy survival benefits rather than suffer losses to health or mating privileges. The study, published Oct. 10 in the open access journal PLOS ONE by Gustavo Santos Requena and colleagues from the University of Sao Paulo, Brazil, evaluates the costs and benefits ...

Body hair in mammals is typically thought to have evolved to keep us warm in colder prehistoric times, but a new study suggests that it may do the opposite, at least in elephants. Epidermal hair may have evolved to help the animals keep cool in the hot regions they live in, according to new research published Oct 10 in the open access journal PLOS ONE by Conor Myhrvold and colleagues at Princeton University. Though the idea that low surface densities of hair can help dissipate heat is a popular concept in engineering, the biological and evolutionary significance of sparse ...

Many parents are dissatisfied with communication regarding adverse drug reactions experienced by their child, and the implications of such reactions for the child's future use of medicines, according to a new study published Oct. 10 in the open access journal PLOS ONE by Bridget Young from the University of Liverpool, UK and colleagues. The researchers interviewed parents of 44 children who had a suspected adverse drug reaction for their study. They found that the majority of parents in their study were dissatisfied with the clarity and timing of communications from ...

AUDIO: This is a mouse song. Click here for more information. Scientists have found the first evidence that the ability to learn vocalizations, a capacity so far believed to be restricted to a handful of bird and mammal species like humans and dolphins, is shared by another species: mice. The new research, published Oct. 10 in the open access journal PLOS ONE by Erich Jarvis and Gustavo Arriaga at Duke University and colleagues, shows for the first time that mice share certain ...

Bad news articles in the media increase women's sensitivity to stressful situations, but do not have a similar effect on men, according to a study undertaken by University of Montreal researchers at the Centre for Studies on Human Stress of Louis-H. Lafontaine Hospital. The findings were published today in PLOS One. The women who participated in the study also had a clearer recollection of the information they had learned. "It's difficult to avoid the news, considering the multitude of news sources out there, said lead author Marie-France Marin. "And what if all that news ...

The remarkably well-preserved fossil of an extinct arthropod shows that anatomically complex brains evolved earlier than previously thought and have changed little over the course of evolution. According to University of Arizona neurobiologist Nicholas Strausfeld, who co-authored the study describing the specimen, the fossil is the earliest known to show a brain. The discovery will be published in the Oct. 11 issue of the journal Nature. Embedded in mudstones deposited during the Cambrian period 520 million years ago in what today is the Yunnan Province in China, the ...

Researchers have published the first highly detailed description of how neurotensin, a neuropeptide hormone which modulates nerve cell activity in the brain, interacts with its receptor. Their results suggest that neuropeptide hormones use a novel binding mechanism to activate a class of receptors called G-protein coupled receptors (GPCRs). "The knowledge of how the peptide binds to its receptor should help scientists design better drugs," said Dr. Reinhard Grisshammer, a scientist at the NIH's National Institute of Neurological Disorders and Stroke (NINDS) and an ...

The well-documented presence of excessive levels of carbon dioxide (CO2) in our atmosphere is causing global temperatures to rise and glaciers and ice caps to melt. New research, published today, 11 October, in IOP Publishing's Journal of Physics D: Applied Physics, has shown that CO2 molecules may be having a more direct impact on the ice that covers our planet. Researchers from the Massachusetts Institute for Technology have shown that the material strength and fracture toughness of ice are decreased significantly under increasing concentrations of CO2 molecules, ...

Who we call and how long we speak to them changes with the weather, according to new research by experts at Newcastle University. Analysing the call patterns of 1.3 million mobile phone users, the team found that in 'uncomfortable' weather – such as very hot, humid, wet or cold weather – call length increased but the number of people we made contact with went down. Apparently "isolating" ourselves during more unpleasant weather, research lead Dr Santi Phithakkitnukoon said the data showed that we were also more likely to contact our close friends and family than our wider ...

A team using the Atacama Large Millimeter/submillimeter Array (ALMA), the most powerful millimetre/submillimetre telescope in the world, has discovered a surprising spiral structure in the gas around the red giant star R Sculptoris [1][2][3]. This means that there is probably a previously unseen companion star orbiting the star [4]. The astronomers were also surprised to find that far more material than expected had been ejected by the red giant. "We've seen shells around this kind of star before, but this is the first time we've ever seen a spiral of material coming ...

DURHAM, N.C. -- Guys who imitate Luciano Pavarotti or Justin Bieber to get the girls aren't alone. Male mice may do a similar trick, matching the pitch of other males' ultrasonic serenades. The mice also have certain brain features, somewhat similar to humans and song-learning birds, which they may use to change their sounds, according to a new study. "We are claiming that mice have limited versions of the brain and behavior traits for vocal learning that are found in humans for learning speech and in birds for learning song," said Duke neurobiologist Erich Jarvis, who ...

PHOENIX, Ariz. — Oct. 10, 2012 — Whole genome sequencing — spelling out all 3 billion letters in the human genome — "is an obvious and powerful method for advancing our understanding of pancreatic cancer," according to a new study from TGen, Mayo Clinic and Scottsdale Healthcare published today. The Translational Genomics Research Institute (TGen) demonstrated that the use of WGS "represents a compelling solution to obtaining detailed molecular information on tumor biopsies in order to provide guidance for therapeutic selection," concluded the study published by the journal ...

PORTLAND, Ore. – Physician-scientists at Oregon Health & Science University Doernbecher Children's Hospital have demonstrated for the first time that banked human neural stem cells — HuCNS-SCs, a proprietary product of StemCells Inc. — can survive and make functional myelin in mice with severe symptoms of myelin loss. Myelin is the critical fatty insulation, or sheath, surrounding new nerve fibers and is essential for normal brain function. This is a very important finding in terms of advancing stem cell therapy to patients, the investigators report, because in most ...

Writing in Nature, Nobel Prize-winner Professor Kostya Novoselov and an international team of authors has produced a 'Graphene Roadmap' which for the first time sets out what the world's thinnest, strongest and most conductive material can truly achieve. The paper details how graphene, isolated for the first time at The University of Manchester by Professor Novoselov and colleague Professor Andre Geim in 2004, has the potential to revolutionise diverse applications from smartphones and ultrafast broadband to anticancer drugs and computer chips. One key area is touchscreen ...

A workshop sponsored by NIH's National Institute of Neurological Disorders and Stroke (NINDS) has produced a set of consensus recommendations to improve the design and reporting of animal studies. By making animal studies easier to replicate and interpret, the workshop recommendations are expected to help funnel promising therapies to patients. Biomedical research involving animals has led to life-saving drugs for heart disease, cancer, stroke, diabetes, HIV-AIDS, and many other conditions, but positive results from animal studies are sometimes difficult to translate ...

A Phase I clinical trial led by investigators from the University of California, San Francisco and sponsored by Stem Cells Inc., showed that neural stem cells successfully engrafted into the brains of patients and appear to have produced myelin. The study, published in the Oct. 10, 2012 issue of Science Translational Medicine, also demonstrated that the neural stem cells were safe in the patients' brains one year post transplant. The results of the investigation, designed to test safety and preliminary efficacy, are encouraging, said principal investigator David H. ...
