  • UTA study finds air contamination near fracking sites result of operational inefficiencies

    Chemists at the University of Texas at Arlington have published a new study that indicates that highly variable contamination events registered in and around unconventional oil and gas developments are the result of operational inefficiencies and not inherent to the extraction process itself.The study, published today as "Point source attribution of ambient contamination events near…

  • Storms in Mexico Kill Millions of Monarchs

    While international efforts are under way to help keep dwindling populations of monarch butterflies from disappearing, scientists are raising concerns about how severe weather and a loss of forest habitat at their wintering grounds in Mexico are affecting them.Every year, monarchs embark on an epic multigenerational migration that takes them thousands of miles from Canada and the…

  • Waterloo chemists develop promising cheap, sustainable battery for grid energy storage

    Chemists at the University of Waterloo have developed a long-lasting zinc-ion battery that costs half the price of current lithium-ion batteries and could help enable communities to shift away from traditional power plants and into renewable solar and wind energy production.Professor Linda Nazar and her colleagues from the Faculty of Science at Waterloo made the…

  • Blending wastewater may help California cope with drought

    Recycled wastewater is increasingly touted as part of the solution to California's water woes, particularly for agricultural use, as the state's historic drought continues. The cost of treating wastewater to meet state health standards for reuse and to reduce salt levels that damage crops presents a new set of challenges, however.Researchers at the University of…

  • Study Suggests First Soda Tax in U.S. Is Working

    As politicians seek ways to combat the obesity epidemic here in the U.S., taxes and even bans on sodas have been floated in cities across the U.S. When former New York Mayor Michael Bloomberg first tried to tax and then limit the size of sodas in the Big Apple, howls of “the nanny state is…

  • Ecological consequences of amphetamine pollution in urban streams

    Pharmaceutical and illicit drugs are present in streams in Baltimore, Maryland. At some sites, amphetamine concentrations are high enough to alter the base of the aquatic food web. So reports a new study released today in the journal Environmental Science & Technology, which is one of the first to explore the ecological consequences of stimulant pollution…

  • Perfluorinated compounds found in African crocodiles, American alligators

    American alligators and South African crocodiles populate waterways a third of the globe apart, and yet both have detectable levels of long-lived industrial and household compounds for nonstick coatings in their blood, according to two studies from researchers at the Hollings Marine Laboratory in Charleston, South Carolina, and its affiliated institutions, which include the National…

  • Sustainable alternative to methyl bromide for tomato production

    Following the phase out of methyl bromide, scientists continue to explore effective, viable, and more sustainable options for vegetable crop production. Among nonchemical alternatives, anaerobic soil disinfestation (ASD) is considered to be one of the most promising methods. ASD has been determined to be effective with a range of crops and environments against several soilborne…

  • New electrical energy storage material shows its power

    A powerful new material developed by Northwestern University chemist William Dichtel and his research team could one day speed up the charging process of electric cars and help increase their driving range.An electric car currently relies on a complex interplay of both batteries and supercapacitors to provide the energy it needs to go places, but…

  • How Elephant Seals Are Helping Scientists Study Climate Change

    A group of southern elephant seals is helping scientists monitorhow climate change is impacting Antarctica by tracking water temperature, depth, and salinity as they swim and dive around the frozen continent.
