EcoHealth Alliance Senior Scientist, Carlos Zambrana-Torrelio, in collaboration with Miguel Fernandez from the German Centre for Integrative Biodiversity Research in coordination with more than 40 Bolivian scientists worked together to create the unique repository. The value of a biological repository ...

LAWRENCE -- A new study based on longitudinal data confirms a college degree provides an advantage in lifetimes earnings, but a related decision once students make it to college could prove to be even more crucial. The study that includes a University of Kansas researcher found large lifetime earnings gaps depending on a student's field of study. For examples, men who major in science, technology, engineering and mathematics, or STEM fields, and earning a bachelor's degree achieved roughly $700,000 to $800,000 higher 40-year lifetime earnings from ages 20 to 59 than social ...

The incidence of the most common strain of Methicillin-resistant Staphylococcus aureus (MRSA) infections has decreased in hospital-onset cases, but has failed to decline in the broader community, according to new research published online today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. The USA 300 strain of MRSA, has become prevalent in both communities and healthcare institutions. "In looking at risk factors for hospital or community-onset USA 300, current or former drug use was a strong predictor ...

Amsterdam, September 16, 2015 - Targeted cancer treatments, toxicity sensors and living factories: synthetic biology has the potential to revolutionize science and medicine. But before the technology is ready for real-world applications, more attention needs to be paid to its safety and stability, say experts in a review article published in Current Opinion in Chemical Biology. Synthetic biology involves engineering microbes like bacteria to program them to behave in certain ways. For example, bacteria can be engineered to glow when they detect certain molecules, and ...

Washington -- A new analysis by the Synthetic Biology Project at the Wilson Center finds the Defense Department and its Defense Advanced Research Projects Agency (DARPA) funds much of the U.S. government's research in synthetic biology, with less than 1 percent of total federal funding going to risk research. The report, U.S. Trends in Synthetic Biology Research, finds that between 2008 and 2014, the United States invested approximately $820 million dollars in synthetic biology research. In that time period, the Defense Department became a key funder of synthetic biology ...

The first true three-dimensional picture of submarine canyon habitats has been produced using a unique combination of marine robotics and ship-based measurements. The information captured in this new set of maps ranges in scale from the 200km canyon down to the size of an individual cold-water coral polyp, and will be used to inform the management of the only English Marine Conservation Zone in deep water. This 'nested map' is the result of a recent scientific expedition to the Whittard Canyon in the Bay of Biscay, led by the National Oceanography Centre (NOC). It works ...

ROCHESTER, Minn. - Mayo Clinic researchers have identified a protein marker whose frequency may predict patient response to PD-1 blockade immunotherapy for melanoma. An abstract of their findings was presented today at the American Association for Cancer Research International Cancer Immunotherapy Conference in New York City. "The discovery of biomarkers of sensitivity are vital not only for informing clinical decisions, but also to help identify which patients with melanoma, and possibly other malignancies, who are most likely to benefit from PD-1 blockade," says Roxana ...

The oil and gas extraction method called hydraulic fracturing remains controversial for multiple reasons, one of which is its water use. But, as scientists report in ACS' journal Environmental Science & Technology Letters, water requirements for the process are potentially lower than those for some other energy-related extraction methods. Since oil and gas companies ramped up hydraulic fracturing, or fracking, to unlock oil and gas from shale and tight oil formations, reports of earthquakes and contaminated water near wells proliferated. Some environmental experts have ...

Detecting breast cancer in women with dense mammary tissues could become more reliable with a new mammogram procedure that researchers have now tested in pre-clinical studies of mice. In their report in the journal ACS Nano, they describe injecting gold nanoparticles in mammary tissue to enhance the imaging of early signs of breast cancer. Mammography remains the clinical gold standard of screening tests for detecting breast cancer. However, a recognized limitation of this X-ray procedure is that dense breast tissue shows up as white masses and fibers on an image, ...

Citizen science is taking off and could make a difference at regional and national regulatory levels. But not everyone thinks that's a good idea. The cover story of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, delves into the progress of the budding movement, as well as the pushback. Steven K. Gibb, senior editor at C&EN, reports that in some states, regulators actively encourage and support local residents' participation in environmental monitoring. For example, Maryland's Department of the Environment and Department ...

Fossils tell amazing stories and inspire them, too -- just think of this summer's "Jurassic World" blockbuster. But because some of the processes that preserve fossils are not well understood, there's still more information that they could reveal. Now scientists report in ACS' journal Analytical Chemistry a new way to probe fossils to find out how these ancient remains formed in greater detail than before. When most organisms die, they biodegrade and leave little behind. But if they get trapped in sediments that harbor few bacteria and loads of dissolved minerals, they ...

Coughing. A sore throat. Maybe a pain in your chest as you take a deep breath. These are all common symptoms for many city-living Australians when smog levels are high. And while it is well understood that smog can cause such problems, new research has for the first time given us a glimpse as to what might be happening at the molecular level. The University of Melbourne's Professor Richard O'Hair, from the School of Chemistry's Bio21 Institute, in collaboration with Professor Stephen Blanksby (from the Queensland University of Technology and formerly the University ...

Researchers from the University of Southampton have demonstrated how a pioneering ultrasonic device can significantly improve the cleaning of medical instruments and reduce contamination and risk of infection. StarStream, invented and patented by the University of Southampton and in commercial production by Ultrawave Ltd., makes water more efficient for cleaning by creating tiny bubbles which automatically scrub surfaces. The device supplies a gentle stream of water through a nozzle that generates ultrasound and bubbles, which dramatically improve the cleaning power of ...

This news release is available in German. Platinum is a great catalyst and can be used for many different applications. It's expensive stuff though, so tiny platinum nanoparticles sitting on cheap metal oxide materials are used to convert harmful carbon monoxide into carbon dioxide. Using scanning tunnelling microscopes, scientists at TU Vienna have now been able to image the catalytic behaviour of platinum sitting on iron-oxide, which allowed them to explain the process on an atomic scale. Surprisingly, the chemical reactions do not take place on the platinum ...

Researchers at the University of Birmingham have shown how the development of coated silica nanoparticles could be used in restorative treatment of sensitive teeth and preventing the onset of tooth decay. The study, published in the Journal of Dentistry, shows how sub-micron silica particles can be prepared to deliver important compounds into damaged teeth through tubules in the dentine. The tiny particles can be bound to compounds ranging from calcium tooth building materials to antimicrobials that prevent infection. Professor Damien Walmsley, from the School of ...

This news release is available in German. Topical research experiments are often too expensive or too complex to be rebuilt and incorporated in teaching. How can one, nevertheless, make modern science accessible to the public? This challenge was tackled in the research group Quantum Nanophysics led by Markus Arndt at the University of Vienna. For the first time, two research laboratories were created as complete, photorealistic computer simulations allowing university and high-school students as well as the general public to virtually access unique instruments. ...

EUGENE, Ore. -- (Sept. 16, 2015) -- New research at the University of Oregon finds that an organization's logo on a food product can trigger quick perceptions by consumers about an item's healthiness and influence their decision-making. That perception also may be seen as an endorsement that may not exist, say study co-authors Elizabeth Minton of the University of Wyoming and T. Bettina Cornwell, the Edwin E. & June Woldt Cone Professor of Marketing in the Lundquist College of Business at the UO. The research, led by Minton as part of her doctoral dissertation at the ...

TORONTO [11 September 2015] A team of astronomers has given us our best view yet of an exoplanet moving in its orbit around a distant star. A series of images captured between November 2013 to April 2015 shows the exoplanet β Pic b as it moves through 1 ½ years of its 22-year orbital period. First discovered in 2008, β Pic b is a gas giant planet ten to twelve times the mass of Jupiter, with an orbit roughly the diameter of Saturn's. It is part of the dynamic and complex system of the star β Pictoris which lies over 60 light-years from Earth. The ...

The use of antidepressants during pregnancy has no long term neurodevelopmental or behavioural effects on the child, however they may be associated with an increased risk of postpartum haemorrhage, suggests the findings from three studies published in BJOG: An International Journal of Obstetrics and Gynaecology (BJOG). Depression and anxiety are the most common mental health problems during pregnancy, with around 12% of women in the UK experiencing depression at some point during pregnancy and the postnatal period. The use of antidepressants such as selective serotonin ...

Stanford University School of Medicine researchers and their colleagues are calling for an urgent re-evaluation of global guidelines for the treatment of parasitic-worm diseases in light of a new study showing that large-scale treatment programs are highly cost-effective. Parasitic-worm diseases afflict some 1.5 billion people in the developing world, causing gastrointestinal problems, anemia, wasting, and cognitive and growth deficits in children, and in some cases, liver, bladder and intestinal problems that can be fatal. About 150,000 people die of complications from ...

CANCER RESEARCH UK scientists have found how cells adapt to overcome cancer drugs designed to interfere with their genetic controls, according to a study* published today (Wednesday) in Epigenetics and Chromatin. Normally molecular 'tags' are attached to DNA which send signals to the cell, telling it how to package its DNA and switch genes on or off. Drugs called HDAC inhibitors cause a build-up of certain types of tags, leading to potentially damaging changes in gene activity that can kill cancer cells. But while HDAC inhibitors can successfully treat certain types ...

An accidental find of a collection of young red dwarf stars close to our solar system could give us a rare glimpse of slow-motion planet formation. Astronomers from The Australian National University (ANU) and UNSW Canberra found large discs of dust around two of the stars, tell-tale signs of planets in the process of forming. "We think the Earth and all the other planets formed from discs like these so it is fascinating to see a potential new solar system evolving," said the lead researcher Dr Simon Murphy, from the ANU Research School of Astronomy and Astrophysics. "However, ...

New research at the University of Warwick with colleagues from the London School of Economics has identified changes in the shape of rainfall across Europe; changes in the amount of drizzle compared with downpours and everything in-between. Professor Sandra Chapman of the University of Warwick and co-authors Professor Nicholas Watkins and Dr David Stainforth from the London School of Economics have today published new research demonstrating how the variability in the way it rains makes it intrinsically difficult to identify the character of local climate change. Difficult ...

HANOVER, N.H. - Warming temperatures are causing Arctic mosquitoes to grow faster and emerge earlier, significantly boosting their population and threatening the caribou they feast on, a Dartmouth College study finds. The study predicts the mosquitoes' probability of surviving and emerging as adults will increase by more than 50 percent if Arctic temperatures rise 2 °C. The findings are important because changes in the timing and intensity of their emergence affect their role as swarming pests of people and wildlife, as pollinators of tundra plants and as food for ...

A total ban on trans fatty acids (trans fats) in processed foods in England could potentially prevent or postpone about 7,200 deaths from coronary heart disease over the next five years, suggest experts in The BMJ this week. They say a total ban in England is "technically feasible" and they call for "decisive action" to prioritise the most effective and cost effective policy options. Industrial trans fatty acids are produced from plant oils (a process known as hydrogenation) and are commonly added to processed foods to cheaply improve shelf life and palatability. Higher ...
