A handful of hyper-productive fisheries provide sustenance to a billion people and employ tens of millions. These fisheries occur on the eastern edges of the world's oceans -- off the West Coast of the U.S., the Canary Islands, Peru, Chile, and Benguela. There, a process called upwelling brings cold water and nutrients to the surface, which in turn supports large numbers of larger sea creatures that humans depend on for sustenance. A new project is seeking to understand how changes to the climate and oceans will impact fisheries in the U.S. and around the world. from Top Environment News -- ScienceDaily https://ift.tt/t2fL74j

New research findings show in detail how self-reactive T cells -- white blood cells dubbed Teffs that mistakenly attack healthy instead of infected cells, thereby causing an autoimmune or an inflammatory response -- are held in check by regulatory T cells, or Tregs. Tregs quickly deploy molecular measures to control rapid proliferation of Teffs, to make sure inflammation is kept in check during an immune response. Tregs biochemically interfere with the protein manufacturing machinery in Teff cells. This hinders their abundant production of proteins, which occurs just before cell division, the researchers found. This rapid Treg intervention reduces the size and number of Teff cells to appropriately manage the magnitude of the immune response. from Top Environment News -- ScienceDaily https://ift.tt/MyT6ZQR

Intact forests are important climate regulators and harbors of biodiversity, but they are rapidly disappearing. Agriculture is commonly considered to be the major culprit behind forest loss, but the authors of a new article show that agriculture isn't solely to blame. For forest loss associated with the 2014 world economy, over 60% was related to final consumption of non-agricultural products, such as minerals, metals and wood-related goods, and the authors argue that we must consider international trade markets when designing conservation strategies. from Top Environment News -- ScienceDaily https://ift.tt/CA9Smuo

In order to meet climate protection goals, renewable energies are booming -- often wind power. More than 30,000 turbines have already been installed on the German mainland so far, and the industry is currently scrambling to locate increasingly rare suitable sites. Thus, forests are coming into focus as potential sites. A scientific team has now demonstrated that wind turbines in forests impair endangered bat species: Common noctules (Nyctalus noctula), a species with a high risk of colliding with rotor blades, are attracted to forest wind turbines if these are located near their roosts. Far from roosts, common noctules avoid the turbines, essentially resulting in a loss of foraging space and thus habitat for this species. from Top Environment News -- ScienceDaily https://ift.tt/wIPftKN

Scientists have decoded the physical process that takes place in the mouth when a piece of chocolate is eaten, as it changes from a solid into a smooth emulsion that many people find totally irresistible. By analyzing each of the steps, the interdisciplinary research team hope it will lead to the development of a new generation of luxury chocolates that will have the same feel and texture but will be healthier to consume. During the moments it is in the mouth, the chocolate sensation arises from the way the chocolate is lubricated, either from ingredients in the chocolate itself or from saliva or a combination of the two. Fat plays a key function almost immediately when a piece of chocolate is in contact with the tongue. After that, solid cocoa particles are released and they become important in terms of the tactile sensation, so fat deeper inside the chocolate plays a rather limited role and could be reduced without having an impact on the feel or sensation of chocolate. from Top En...

A study examined the effects of anthropogenic noise on cognition, beak color, and growth in the zebra finch. Researchers first tested adult zebra finches on a battery of cognition assays while they were exposed to playbacks of urban noise versus birds tested without noise. Urban noises caused the birds to take longer to learn a novel foraging task and to learn an association-learning task. Urban noise exposure also resulted in treated males to develop less bright beak coloration, and females developed beaks with brighter orange coloration, respectively, than untreated birds. Findings suggest that urban noise exposure may affect morphological traits, such as beak color, which influence social interactions and mate choice. from Top Environment News -- ScienceDaily https://ift.tt/U1Aq79V
