He then groups different definitions ...

How are environmental changes, loss of biodiversity, and the spread of pathogens connected? The answer is a puzzle. Scientists from Charité – Universitätsmedizin Berlin in cooperation with the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) have now described one piece of that puzzle in the journal “eLife”, showing that the destruction of tropical rainforests harms the diversity of mosquito species. At the same time, more resilient species of mosquitoes become more prevalent – which also means the viruses they carry are more abundant. If there are many individuals of a given ...

With a variety of flavors and widespread perceptions of safety, e-cigarettes appeal to an array of users and especially to adolescents. E-cigarette use, however, is linked to increased alcohol consumption, as well as the use of other substances and drugs. The health effects of such combinations remain almost entirely unknown. Now, with new funding from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) of the National Institutes of Health (NIH), researchers at the Lewis Katz School of Medicine at Temple University hope ...

About The Study: In this study of working-age adults with multiple sclerosis (MS), premorbid income, education, and marital status correlated with disability and symptom severity in relapse onset and progressive-onset MS, independent of treatment. These findings suggest that socioeconomic status may reflect both structural and individual determinants of health in MS. Authors: Anna He, M.B.B.S., of the Karolinska Institute in Stockholm, Sweden is the corresponding author. To access the embargoed study: Visit our ...

About The Study: In this study of 69,000 adults with hepatitis C virus (HCV) infection, there was no difference in sustained virologic response across alcohol use categories, even for patients with high-risk consumption or alcohol use disorder, after adjusting for potential confounding variables. These findings suggest that restricting access to direct-acting antiviral therapy on the basis of alcohol use creates an unnecessary barrier for patients and challenges HCV elimination goals. Authors: Emily J. Cartwright, M.D., of the Emory University School of Medicine in Atlanta, ...

Earthworms are important drivers of global food production, contributing to approximately 6.5% of grain yield and 2.3% of legumes produced worldwide each year, according to new work published by Colorado State University scientists in the journal Nature Communications.     These new estimates from a trio of CSU researchers mean earthworms may account for as much as 140 million metric tons of food produced annually — roughly comparative to the amount of cereal grains (rice, wheat, rye, oats, barley, maize and millet) ...

Leipzig. The decline in invertebrates also affects the functioning of ecosystems, including two critical ecosystem services: aboveground pest control and belowground decomposition of organic material, according to a new study published in Current Biology and led by researchers at the German Centre for Integrative Biodiversity Research (iDiv) and Leipzig University. The study provides evidence that loss of invertebrates leads to a reduction in important ecosystem services and to the decoupling of ecosystem processes, making immediate protection measures necessary. Invertebrates, such as insects and also ...

Nitrogen is an essential nutrient for plant growth, but the overuse of synthetic nitrogen fertilizers in agriculture is not sustainable. In a review article publishing in the journal Trends in Microbiology on September 26, a team of bacteriologists and plant scientists discuss the possibility of using genetic engineering to facilitate mutualistic relationships between plants and nitrogen-fixing microbes called “diazotrophs.” These engineered associations would help crops acquire nitrogen from the air by mimicking the mutualisms between legumes and nitrogen-fixing bacteria. “Engineering associative diazotrophs to provide nitrogen ...

A new study finds that consanguinity – unions between close relatives - may increase the risk of common diseases such as type 2 diabetes and post-traumatic stress disorder (PTSD). Researchers from the Wellcome Sanger Institute and their collaborators at Queen Mary University of London analysed the genomic data of diverse groups to investigate the relationship between autozygosity - a measure of genetic relatedness between an individual’s parents - and the prevalence of common diseases, with a novel method that reduces confounding due to sociocultural factors. They focused ...

Metal nanoclusters are tiny, crystalline structures up to two nanometers (2 x 10-9 meters) in diameter that contain a few to hundreds of metal atoms.  Understanding the precise assembly of metal nanoclusters is paramount to determining how different structures affect the properties and molecular interactions of these materials.  Researchers recently synthesized two similar gold-silver (Au9Ag6) nanoclusters in a highly controlled manner to determine the precise atomic structure of each nanocluster and the effects of specific thiol ligands, or sulfur-containing binding molecules, on material synthesis.   Given their extremely small size, metal nanoclusters have ...

(Santa Barbara, Calif.) — What makes for a successful climate-resilient fishery, one that sustainably produces resources for human benefit despite increasing climate stressors and human impacts? It’s a question that faces present and future fisheries, their practitioners and fishing communities as the world turns to the ocean to feed its growing population.   “For a fishery to be resilient it needs to be able to prepare for, resist, cope with, recover from, or adapt to any given impact,” said Jacob Eurich, who is a research associate at UC Santa Barbara’s Marine Science Institute, and a fisheries scientist at the Environmental Defense Fund (EDF). “In ...
