  • Eco-friendly water treatment works best with experienced bacterial flora
    on May 14, 2018 at 1:15 pm

    Sustainable, biological filters called slow sand filters have been used to filter drinking water since the 1800s. They don't use any chemicals, create no waste and use very little energy. New research shows that not only are the older filters more efficient cleaners -- they could be making a comeback soon with the help of new technology. […]

  • Engineered polymer membranes could be new option for water treatment
    on May 4, 2018 at 4:23 pm

    The world's freshwater resources are in short supply. According to the United Nations, water scarcity affects an estimated 1.9 billion people and 2.1 billion people live with drinking water services that are not safely managed. The critical point of water scarcity has led scientists to look for new and efficient ways to make the most of nontraditional sources, including sea water, brackish water and wastewater. […]

  • A potentially cheap, efficient and eco-friendly system for purifying natural gas
    on May 3, 2018 at 7:42 pm

    Fundamental researchers have proposed a novel two-part system for separating impurities from natural gas. Natural gas primarily contains methane, but impurities in the gaseous mixture need to be removed before the methane can be put into the pipeline. The newly proposed purification system combines two separation methods and, in principle, promises to improve performance, reduce costs and diminish ecological side effects compared to benchmark technologies. […]

  • Energy recovery of urban waste
    on May 2, 2018 at 2:40 pm

    Researchers have proposed a system which is capable of converting waste in a more controlled manner, and, basically, in two stages: first, the solid is converted to gas in reducing conditions (that is, with the presence of little oxygen), and then the generated gas is burnt very efficiently in specifically optimized equipment. […]

  • Changing cities' food systems to help reduce carbon emissions
    on May 2, 2018 at 12:31 pm

    Many US cities and states are looking for ways to slash greenhouse gas emissions, including cap-and-trade programs, building-efficiency regulations, and boosting public transit and renewable energy sources. Now scientists report additional measures cities could take to further cut their carbon footprint: by tackling emissions related to food consumption and waste. […]

  • Fracking the immune system
    on May 1, 2018 at 12:55 pm

    Researchers are the first to report links between early life exposure to chemicals in ground water near fracking sites and immune system imbalances in mice. Their findings suggest that exposure to these chemicals during development may adversely affect the immune system's ability to fight diseases like multiple sclerosis later in life. […]

  • Bacteria's appetite may be key to cleaning up antibiotic contamination
    on April 30, 2018 at 5:19 pm

    Some bacteria can not only withstand antibiotics, but turn them into food. Until now, scientists have understood little about how bacteria manage to consume antibiotics safely, but new research illuminates key steps in the process. The findings could lead to new ways to eliminate antibiotics from land and water, the researchers said. Environmental antibiotic contamination promotes drug resistance and undermines our ability to treat bacterial infections. […]

  • 'Infinitely' recyclable polymer shows practical properties of plastics
    on April 26, 2018 at 6:15 pm

    The world fell in love with plastics because they're cheap, convenient, lightweight and long- lasting. For these same reasons, plastics are now trashing the Earth. Chemists have just announced another major step toward waste-free, sustainable materials that could one day compete with conventional plastics. […]

  • Europe's current approach to food, agriculture, and the environment is not sustainable
    on April 26, 2018 at 2:29 pm

    The European Academies' Science Advisory Council along with the InterAcademy Partnership are calling for European policy-makers to urgently re-think their approach to food and agriculture. Calling for a 'food systems approach,' the national science academies say that the current siloed policy approach to food, agriculture, climate change, and health -- both at the EU and Member State levels -- is not the way forward. […]

  • As tellurium demands rise, so do contamination concerns
    on April 25, 2018 at 1:38 pm

    As technology advances, demands for tellurium, a rare element, are on the rise. Some forms of tellurium are toxic, so as the element finds applications in solar panels, rubber production, electronics and more, researchers are becoming concerned about possible environmental contamination. Now, one group reports that by studying lake sediments they can construct a history of tellurium as it was deposited in the environment. […]

    on April 20, 2018 at 4:29 pm

    A new recycling process turns discarded hard disk drive magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable materials. […]

  • Soil metals linked with cancer mortality
    on April 20, 2018 at 4:28 pm

    Epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels. These statistical links do not indicate that there is a cause-effect relationship between soil type and cancer, but they suggest that the influence of metals from the earth's surface on the geographical distribution of tumors should be analyzed. […]

  • Remnants of antibiotics persist in treated farm waste
    on April 12, 2018 at 7:45 pm

    Each year, farmers in the US purchase tens of millions of pounds of antibiotics approved for use in cows, pigs, fowl and other livestock. When the animals' manure is repurposed as fertilizer or bedding, traces of the medicines leach into the environment, raising concerns about how agriculture contributes to the rise of antibiotic-resistant bacteria. New research holds troublesome insights with regard to the scope of this problem. […]

  • Faster, cheaper wastewater treatment through improved oxidation reactions
    on April 12, 2018 at 5:08 pm

  • Swamp microbe has pollution-munching power
    on April 11, 2018 at 8:13 pm

    Sewage treatment may be an unglamorous job, but bacteria are happy to do it. Sewage plants rely on bacteria to remove environmental toxins from waste so that the processed water can be safely discharged into oceans and rivers. Now, a bacterium discovered in a New Jersey swamp may offer a more efficient method for treating toxins found in sewage, fertilizer runoff and other forms of water pollution. […]
