  • Peace, equality and prosperity all depend on affordable clean energy, study shows
    on November 20, 2017 at 1:59 pm

    The UN’s 17 Sustainable Development Goals are aimed at achieving equality, securing global peace and ending extreme poverty – an ambitious agenda that will require a wide-range of conditions to be met. But one requirement lies at the center of most of the SDGs: that people have access to clean, affordable energy, says a new study. […]

  • 'Explosive' hot oil droplets could hurt your skin -- and air quality
    on November 19, 2017 at 4:18 pm

    Cooking in a frying pan with oil can quickly become dangerous if “explosive” hot oil droplets jump out of the pan, leading to painful burns. But these droplets may be doing something even more damaging: contributing to indoor air pollution. […]

  • One in ten historic coastal landfill sites in England are at risk of erosion
    on November 16, 2017 at 12:52 am

    There are at least 1,215 historic coastal landfill sites in England, mostly clustered around estuaries with major cities, including Liverpool, London, and Newcastle on Tyne. An investigation by researchers finds that 122 sites are at risk of starting to erode into coastal waters by 2055 if not adequately protected. […]

  • Pulling iron out of waste printer toner
    on November 15, 2017 at 4:50 pm

    Someday, left-over toner in discarded printer cartridges could have a second life as bridge or building components instead of as trash, wasting away in landfills and potentially harming the environment. A research group reports that they have devised a method to recycle the residual powder in 'empty' cartridges into iron using temperatures that are compatible with existing industrial processes. […]

  • Public – and researchers – skeptical about climate engineering
    on November 15, 2017 at 2:22 pm

    What does the general public know about climate engineering, and what do they think about what they know? These were questions asked by researchers. […]

  • Organic farming can make an important contribution to world nutrition, research shows
    on November 15, 2017 at 2:21 pm

    A global conversion to organic farming can contribute to a profoundly sustainable food system, provided that it is combined with further measures, specifically with a one-third reduction of animal-based products in the human diet, less concentrated feed and less food waste, shows new research. […]

  • Low dose, constant drip: Pharmaceutical, personal care pollution impacts aquatic life
    on November 14, 2017 at 5:33 pm

    Traditional toxicity testing underestimates the risk that pharmaceutical and personal care product pollution poses to freshwater ecosystems. Criteria that account for ecological disruption -- not just organism death -- are needed to protect surface waters, which are under pressure from a growing population and escalating synthetic chemical use. […]

  • A fast reactor system to shorten the lifetime of long-lived fission products
    on November 14, 2017 at 2:12 pm

    Researchers have proposed a more efficient method to reduce radioactive waste. The study involves converting radioactive material into short-lived nuclides by absorbing surplus neutrons in the core peripheral portion of a small fast reactor faster than they are generated in the core, thus providing an effective way to lessen the burden of nuclear waste on future generations. […]

    on November 1, 2017 at 12:27 am

    Eating “clean” is all about avoiding foods with additives, preservatives or other chemicals on the label. Two professors are warning of the consequences associated with the clean food movement in terms of food waste, safety and cost. […]

  • Discarded cigarette butts: The next high performing hydrogen storage material?
    on October 31, 2017 at 4:05 pm

  • Cobalt and tungsten key to cheaper, cleaner hydrogen
    on October 30, 2017 at 5:46 pm

    Electrolysis, splitting the water molecule with electricity, is the cleanest way to obtain hydrogen, a clean and renewable fuel. Now, researchers have designed a new catalyst that reduces the cost of electrolytic hydrogen production. Catalysts reduce the amount of electricity needed to break the chemical bonds, speed up the reaction and minimize the energy waste. […]

  • From Cellulose to 3-D Objects
    on October 27, 2017 at 4:27 pm

    In our modern world, eliminating plastics is inconceivable. Unfortunately, they do have disadvantages, including the formation of CO(2) in both production and combustion, depletion of fossil feedstocks, and growth of landfills. Researchers have now introduced a new way forward, a polymer made entirely from biomass that can easily and inexpensively be used in 3-D printing. Objects produced in this way are of high quality, easily recyclable, and highly solvent-resistant. […]

  • Determining when humans started impacting the planet on a large scale
    on October 25, 2017 at 1:05 pm

    Humans have so profoundly altered the Earth that, some scientists argue, our current geologic epoch requires a new name: the Anthropocene. But defining the precise start of the era is tricky. Would it begin with the spread of domesticated farm animals or the appearance of radioactive elements from nuclear bomb tests? Scientists report a method to measure levels of human-made contaminants in sediments that could help pinpoint the Anthropocene's onset. […]

  • Novel nanoparticle to remove cadmium from freshwater
    on October 25, 2017 at 3:28 am

    Researchers have tested the capability of a novel nanoparticle to remove cadmium toxicity from a freshwater system. […]

  • Raton Basin earthquakes linked to oil and gas fluid injections
    on October 24, 2017 at 6:17 pm

    A rash of earthquakes in southern Colorado and northern New Mexico recorded between 2008 and 2010 was likely due to fluids pumped deep underground during oil and gas wastewater disposal, suggests a new study. […]

  • Arsenic can cause cancer decades after exposure ends
    on October 24, 2017 at 3:56 pm

    Arsenic in drinking water may have one of the longest dormancy periods of any carcinogen. By tracking the mortality rates of people exposed to arsenic-contaminated drinking water in a region in Chile, the researchers provide evidence of increases in lung, bladder, and kidney cancer even 40 years after high arsenic exposures ended. […]

  • Illinois sportfish recovery a result of 1972 Clean Water Act, scientists report
    on October 18, 2017 at 4:17 pm

    Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say. […]

  • Arsenic in domestic well water could affect 2 million people in the US
    on October 18, 2017 at 1:02 pm

    Clean drinking water can be easy to take for granted if your home taps into treated water sources. But more than 44 million people in the U.S. get their water from private domestic wells, which are largely unregulated. Of those, a new report estimates that about 2 million people could be exposed to high levels of naturally occurring arsenic in their water. […]

  • Rivers carry plastic debris into the sea
    on October 17, 2017 at 3:00 pm

    Every year, millions of tons of plastic debris ends up in the sea. The path taken by plastic to reach the sea must be elucidated before it will be possible to reduce the volume of plastic input. To date, there was only little information available on this. It has now been followed up by an interdisciplinary research team who were able to show that plastic debris is primarily carried into the sea by large rivers. […]

  • Gutters teem with inconspicuous life
    on October 13, 2017 at 5:22 pm

    Scientists have shown that Parisian street gutters are oases of microscopic life, home to microalgae, fungi, sponges, and mollusks. Grouped into communities, these microorganisms may help clean rainwater and urban waste by decomposing solid debris and pollutants. A deeper understanding of the role and composition of these communities could help elucidate the services rendered by gutter ecosystems. The researchers' findings are the first to reveal the unsuspected biodiversity of microscopic life in Paris city streets. […]
