  • Air pollution may disrupt sleep
    High levels of air pollution over time may get in the way of a good night's sleep, according to new research.... Read more »
  • Triple play boosting value of renewable fuel could tip market in favor of biomass
    true
    A new process triples the fraction of biomass converted to high-value products to nearly 80 percent, also tripling the expected rate of return for an investment in the technology from roughly 10 percent (for one end product) to 30 percent.... Read more »
  • Traffic-related air pollution linked to DNA damage in children
    true
    Children and teens exposed to high levels of traffic-related air pollution have evidence of a specific type of DNA damage called telomere shortening, reports a new study.... Read more »
  • Kamchatkan volcanic ash travels half the world
    true
    Geochemical fingerprinting links microscopic ash found on the bottom of a Svalbard lake to volcanic event happening 7,000 years ago and 5,000 km away.... Read more »
  • Environmental pollutants in large Norwegian lakes
    true
    Scientists have discovered the presence of contaminants in the pelagic food chains in the lakes Mjøsa, Randsfjorden and Femunden in Norway, and in supplementary material of fish from Tyrifjorden and Vansjø, sampled in 2015. Mercury and persistent organic pollutants (cVMS, PCBs, PBDEs, PFAS) were analyzed in samples of fish from all... Read more »
  • Fueling the future
    true
    New research investigated the full life cycle impact of one promising 'second-generation biofuel' produced from short-rotation oak. The study found that second-generation biofuels made from managed trees and perennial grasses may provide a sustainable fuel resource.... Read more »
  • Sea level as a metronome of Earth's history
    true
    Sedimentary layers contain stratigraphic cycles and patterns that precisely reveal the succession of climatic and tectonic conditions that have occurred over millennia. Researchers have been working on an analytical method that combines observing deep-water sedimentary strata and measuring in them the isotopic ratio between heavy and light carbon. They have...

  • Iron deficiency restrains marine microbes
    Iron is a critical nutrient in the ocean. Its importance for algae and the nitrogen cycle has already been investigated in detail. Now a new discovery shows that microbes also need iron to process phosphorus. A team of researchers has completed a study showing that iron can limit phosphorus acquisition... Read more »
  • Insight into enzyme's 3-D structure could cut biofuel costs
    true
    Using neutron crystallography, research team has mapped the three-dimensional structure of a protein that breaks down polysaccharides, such as the fibrous cellulose of grasses and woody plants, a finding that could help bring down the cost of creating biofuels.... Read more »
  • Smoking out sources of in-home air pollution
    true
    An ambitious study has investigated various factors that contribute to air pollution inside the house. Not surprisingly, cigarette smoke emerged as a major source of airborne particles in homes with smokers, but cleaning products, candles, frying food and marijuana smoking also jumped out as in-home air polluters. It's the first... Read more »
