Barcelona, Friday 19 April 2013.- Yellow vision, pseudo-pulmonary obstruction, involuntary body movements, respiratory paralysis. These are some of the 1,600 known side effects (SEs) produced by drugs. Adverse effects are one of the main causes of hospital admission in the west. These effects are difficult to predict, and in practice specific assays are required to test the safety of agents in pre-clinical phases, thus these effects are often not discovered until the drug has been launched. A study published by scientists at the Institute for Research in Biomedicine (IRB ...

Young people seeking help who are at high risk of developing psychosis could significantly reduce their chances of going on to develop a full-blown psychotic illness by getting early access to cognitive behavioural therapy (CBT), new research shows. Researchers from The University of Manchester found the risk of developing psychosis was more than halved for those receiving CBT at six, 12 and 18-24 months after treatment started. The team from the University's School of Psychological Science and the Psychosis Research Unit at Greater Manchester West Mental Health NHS ...

A smaller proportion of black carbon created during combustion will remain in soil than have been estimated before. Contrary to previous understanding, burying black carbon in the ground in order to restrain climate change will not create a permanent carbon reserve. Instead, a part of black carbon will dissolve from soil to rivers. The flux of dissolved black carbon from the rivers to the ocean was estimated in a research article published in Science on 19 April. The burning of organic matter creates 40 million tons of black carbon every year. Black carbon is formed through ...

New research, just published, details how University of Cincinnati researchers have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources – lakes and rivers – at a significantly higher rate than the currently used filtering technology made of activated carbon. In the journal "Nano Letters," Vikram Kapoor, environmental engineering doctoral student, and David Wendell, assistant professor of environmental engineering, report on their development and testing of the new filter made of two bacterial proteins ...

A major Nordic research project involving researchers from the University of Copenhagen has, for the first time ever, mapped the use of alternative treatment among multiple sclerosis patients - knowledge which is important for patients with chronic disease and the way in which society meets them. People with multiple sclerosis (MS) often use alternative treatments such as dietary supplements, acupuncture and herbal medicine to facilitate their lives with this chronic disease. This is the result of a new study of how MS patients use both conventional and alternative treatments ...

AUDIO: This is a North American red squirrel emitting a territorial vocalization called a "rattle ". Click here for more information. Stressed-out mothers raise stronger, heartier offspring – at least among squirrels. In a new study, international researchers – including University of Guelph biologists – say squirrels tailor their parenting to meet the varied conditions facing their young. For pups born during crowded, stressful times, mama squirrels kick ...

This year marks the 23rd year of observing for the Hubble Space Telescope. Alongside cutting-edge science, the orbiting observatory has produced countless stunning astronomical images. Some of the most striking and beautiful subjects of Hubble's images have been nebulae -- vast interstellar clouds of gas and dust. This new Hubble image, captured and released to celebrate this milestone, shows part of the sky in the constellation of Orion (The Hunter). Rising like a giant seahorse from turbulent waves of dust and gas is the Horsehead Nebula, otherwise known as Barnard ...

A long-forgotten candidate for antiviral therapy is undergoing a renaissance: Since the 1970s, the small molecule CMA has been considered a potent agent against viral infections, yet it was never approved for clinical use. Scientists at the Bonn University Hospital have now deciphered how the molecule can actually stimulate the immune system to combat viruses. The results are now being presented in the journal "EMBO" of the European Molecular Biology Organization. Finding an active substance to stimulate the immune system and thus better combat dangerous viruses has been ...

Astronomers have used NASA's Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory's launch aboard the space shuttle Discovery on April 24, 1990. Looking like an apparition rising from whitecaps of interstellar foam, the iconic Horsehead Nebula has graced astronomy books ever since its discovery more than a century ago. The nebula is a favorite target for amateur and professional astronomers. It is shadowy in optical light. It appears transparent and ethereal when seen at infrared ...

PHILADELPHIA — Smoking tobacco in a water pipe resulted in a different pattern of exposure to toxic substances and may result in a cancer risk profile that is different from that of cigarette smoking, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. "Water-pipe smoking at 'hookah bars' has become popular with young people in the United States, and some believe that it is less harmful than cigarette smoking," said Peyton Jacob III, Ph.D., a University of California, San Francisco research ...

ANN ARBOR, Mich. — A new study debunks the myth that younger moms are more likely to "bounce back" after having a baby – teenage pregnancy actually makes women more likely to become obese. Women who give birth as teens are significantly more likely to be overweight or obese later in life than women who were not teen moms, University of Michigan Health System researchers found. The nationally representative study, which is the first believed to identify teen pregnancy as a predictor of obesity, appears in the American Journal of Obstetrics & Gynecology. "When taking ...

Smart electronics are taking the world by storm. From techno-textiles to transparent electronic displays, the world of intelligent technology is growing fast and a revolutionary new device has just been added to its ranks. Researchers at the University of Exeter have developed a new photoelectric device that is both flexible and transparent. The device, described in a paper in the journal ACS Nano, converts light into electrical signals by exploiting the unique properties of the recently discovered materials graphene and graphExeter. GraphExeter is the best known room temperature ...

NORMAN – Fishes account for over half of vertebrate species, but while groups such as mammals, birds and reptiles have been fairly well understood by scientists for decades, knowledge about relationships among many types of fishes was essentially unknown – until now. A team of scientists led by Richard Broughton, associate professor of biology in the College of Arts and Sciences at the University of Oklahoma, published two studies that dramatically increase understanding of fish evolution and their relationships. They integrated extensive genetic and physical information ...

MANHASSET, NY – A researcher at The Feinstein Institute for Medical Research has discovered additional mechanical properties of articular cartilage, a protective cartilage on the ends of bones that wears down over time, resulting in the development of osteoarthritis. The findings are published in the April issue of PLOS ONE. To better understand the onset and progression of osteoarthritis, Nadeen Chahine, PhD, and collaborators at other institutions looked at cells from articular cartilage using atomic force microscopy (AFM). They used this technology to measure the mechanical ...

SALT LAKE CITY, April 18, 2013 – When superstorm Sandy turned and took aim at New York City and Long Island last October, ocean waves hitting each other and the shore rattled the seafloor and much of the United States – shaking detected by seismometers across the country, University of Utah researchers found. "We detected seismic waves created by the oceans waves both hitting the East Coast and smashing into each other," with the most intense seismic activity recorded when Sandy turned toward Long Island, New York and New Jersey, says Keith Koper, director of the University ...

Highlights The phosphate binder sevelamer carbonate did not improve cardiovascular measures in patients with early chronic kidney disease. For now, reducing dietary intake of phosphate may be the best way for these patients to reduce the mineral's negative effects on the heart. High phosphate levels—in kidney disease patients and in the general population—increase the risk of dying from cardiovascular causes. Washington, DC (April 18, 2013) — High phosphate levels in the blood carry increased heart-related risks, but taking a drug that targets phosphate does ...

Highlights In patients with chronic kidney disease, measures of lower extremity performance were at least 30% lower than predicted, but handgrip strength was relatively preserved. Each 0.1-meter per second slower walking speed was linked with a 26% higher risk for death over an average three-year follow-up period. Adding gait speed tests to laboratory tests of kidney function significantly improved the prediction of three-year mortality. 60 million people globally have chronic kidney disease. Washington, DC (April 18, 2013) — Kidney disease patients who have ...

People who participate in community gardening have a significantly lower body mass index—as well as lower odds of being overweight or obese—than do their non-gardening neighbors. Researchers at the University of Utah reported these and other findings in the American Journal of Public Health published online today. "It has been shown previously that community gardens can provide a variety of social and nutritional benefits to neighborhoods," says Cathleen Zick, lead author of the study and professor of family and consumer studies at the University of Utah. "But until now, ...

Frontiers in Psychology Numerical cognition in bees and other insects In this article, Dr. Mario Pahl and colleagues review the main studies on the ability of insects to perceive number, and discuss the possible mechanisms involved in number recognition. Recent behavioral investigations have shown that several invertebrate species (animals without backbones) share various numerical activities with bigger animals, such as birds and mammals. This is because the ability to assess the number of food items, competitors or mates can help animals – even smaller ones like insects ...

In one of the most detailed studies of its kind, a team of Greek and U.S. researchers have vividly chronicled the harmful public health impacts of the economic austerity measures imposed on Greece's population in the wake of the global economic crisis. Writing in today's [Thursday, April 18] American Journal of Public Health, the researchers cite data showing the economic recession and subsequent austerity policies in Greece have led to a sharp deterioration of health services and health outcomes. Researchers at the Aristotle University of Thessaloniki in Greece and ...

College Park, MD - A new study of brain rhythms in bats and rats challenges a widely used model - based on studies in rodents - of how animals navigate their environment. To get a clearer picture of the processes at work in the mammal brain during spatial navigation, neuroscientists must closely study a broad range of animals, say the two University of Maryland College Park scientists involved in the study. In the April 19, 2013 issue of Science, the University of Maryland researchers and two colleagues at Boston University reported significant differences between rats' ...

Claremont, CA – The first new species of dinosaur from Madagascar in nearly a decade was announced today, filling an important gap in the island's fossil record. Dahalokely tokana (pronounced "dah-HAH-loo-KAY-lee too-KAH-nah") is estimated to have been between nine and 14 feet long, and it lived around 90 million years ago. Dahalokely belongs to a group called abelisauroids, carnivorous dinosaurs common to the southern continents. Up to this point, no dinosaur remains from between 165 and 70 million years ago could be identified to the species level in Madagascar–a 95 ...

The proportion of young women diagnosed with genital warts in Australia has seen a significant decline thanks to the HPV vaccine, suggests a paper published today on bmj.com. In 2007, Australia became one of the first countries to implement a nationally funded quadrivalent human papillomarivus (HPV) vaccination programme for girls and young women, which offers free vaccinations to girls aged 12-13 years in schools. From 2007 – 2009 there were a further two catch-up programmes: for 13-18 year olds and 18-26 year olds. The vaccine protects against the types of HPV that ...

Menstrual problems among adolescents with learning and physical disabilities are more common compared to the general population and there is no one-size fits all solution when managing the symptoms, says a new review published today (19th April) in The Obstetrician & Gynaecologist (TOG). The review looks at the behavioural and emotional changes associated with menstruation in adolescents with learning and physical disabilities and examines the advantages and limitations of therapeutic and surgical options for managing menstrual problems. Menstrual problems in girls ...

Additional legislation and guidance around surrogate pregnancy is needed for healthcare professionals, says a new review published today (19th April) in The Obstetrician & Gynaecologist (TOG). The review looks at the medico-legal challenges of surrogacy in modern obstetrics, highlighting recent changes in UK laws, the guidelines and legislation available and the legal requirements for parenthood and parental rights. The number of surrogate pregnancies in the UK is unknown, since many arrangements proceed without any medical or legal input, states the review. In April ...
