Published Controlling water, transforming greenhouse gases
(via sciencedaily.com) Original source Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.
Published Developing novel methods to detect antibiotics in vegetables and earthworms
(via sciencedaily.com) Original source Researchers have managed to analyze, simultaneously, several families of antibiotics in vegetables and earthworms. Sampling carried out in various locations has yielded data on the existence of antimicrobial agents and their derivatives in vegetables. In this respect, Vergara stresses the need for further research to address the problem of contamination by this type of medication in the environment.
Published Charting a pathway to next-gen biofuels
(via sciencedaily.com) Original source From soil to sequestration, researchers have modeled what a supply chain for second-generation biofuels might look like in the midwestern United States.
Published Iron could be key to less expensive, greener lithium-ion batteries, research finds
(via sciencedaily.com) Original source Chemistry researchers are hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries.
Published Shedding light on the chemical enigma of sulfur trioxide in the atmosphere
(via sciencedaily.com) Original source Researchers discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. These previously uncharacterized acid sulfuric anhydride products are almost certainly key contributors to atmospheric new particle formation and a way to efficiently incorporate carboxylic acids into atmospheric nanoparticles. Better prediction of aerosol formation can help curb air pollution and reduce uncertainties concerning climate change.
Published Rising temperatures will significantly reduce streamflow in the upper Colorado river basin as groundwater levels fall
(via sciencedaily.com) Original source The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river's water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.
Published Chemist developing method to recycle more plastics
(via sciencedaily.com) Original source To improve recycling rates a professor is working on new ways to separate and recycle mixed plastics.
Published How the 'home' environment influences microbial interactions
(via sciencedaily.com) Original source A new study shows that real-world ocean conditions make a huge difference in how viral infection affects host bacteria. The findings indicate it is very important to study cells and virocells under nutrient conditions that more closely resemble what they encounter in nature.
Published Social networks can influence perception of climate-change risk
(via sciencedaily.com) Original source Short but severe episodes of flooding from hurricanes in Texas and Florida triggered a nationwide increase in flood insurance sign-ups depending on how socially connected a county was to the flooded counties.
Published Promethium bound: Rare earth element's secrets exposed
(via sciencedaily.com) Original source Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.
Published 'Fossilizing' cracks in infrastructure creates sealing that can even survive earthquakes
(via sciencedaily.com) Original source In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials.
Published New polystyrene recycling process could be world's first to be both economical and energy-efficient
(via sciencedaily.com) Original source Engineers have modeled a new way to recycle polystyrene that could become the first viable way of making the material reusable.
Published New insights into the degradation dynamics of organic material in the seafloor
(via sciencedaily.com) Original source Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.
Published Alaska's rusting waters: Pristine rivers and streams turning orange
(via sciencedaily.com) Original source Dozens of Alaska's rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study.
Published Night-time heat significantly increases the risk of stroke
(via sciencedaily.com) Original source Researchers show that nocturnal heat significantly increases the risk of stroke. The findings can contribute to the development of preventive measures: With them, the population can better protect themselves against the risks of climate change with increasingly frequent hot nights. In addition, knowledge of the consequences of hot nights can improve patient care.
Published Researchers find unique adaptations of fungus associated with bee bread
(via sciencedaily.com) Original source The past attempts of honey bee researchers to inventory the fungal diversity in honey bee colonies revealed that Aspergillus flavus is frequently found in hives. In a new study, researchers have discovered that this fungus is uniquely adapted to survive in bee colonies.
Published Warming climate intensifies flash droughts worldwide
(via sciencedaily.com) Original source Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.
Published Can coal mines be tapped for rare earth elements?
(via sciencedaily.com) Original source A team of geologists analyzed 3,500 samples taken in and around coal mines in Utah and Colorado. Their findings open the possibility that these mines could see a secondary resource stream in the form of rare earth metals used in renewable energy and numerous other high-tech applications.
Published The impacts of climate change on food production
(via sciencedaily.com) Original source A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.
Published Unraveling the drought dilemma: Can reservoirs be a carbon source?
(via sciencedaily.com) Original source A team delves into the spatiotemporal patterns of water volume and total organic carbon concentration of agricultural reservoirs.
