  • New studies explore how knowledge drives action in climate change decision-making
    In several new studies, researchers explore the importance of learning and knowledge in environmental decision-making and the different ways in which scientific knowledge can become more relevant and useful for societies.... Read more »
  • For 'blade runners' taller doesn't necessarily mean faster
    The governing body for the Paralympics recently lowered the allowable height for sprinters who use prosthetic legs, or blades, during competition. The rules are based on the assumption that the taller you are the faster you run. But a new study has found otherwise.... Read more »
  • A better pregnancy test for whales
    To determine whale pregnancy, researchers have relied on visual cues or hormone tests of blubber collected via darts, but the results were often inconclusive. Research points to a weakness of previous testing and evaluation methods and provides a new hormone testing regime that offers better results.... Read more »
  • Water reuse could be key for future of hydraulic fracturing
    Enough water will come from the ground as a byproduct of oil production from unconventional reservoirs during the coming decades to theoretically counter the need to use fresh water for hydraulic fracturing operations in many of the nation's large oil-producing areas. While other industries might want to recycle some of... Read more »
  • Fifty years of data show new changes in bird migration
    A growing body of research shows that birds' spring migration has been getting earlier and earlier in recent decades. New research on Black-throated Blue Warblers, a common songbird that migrates from Canada and the eastern US to Central America and back every year, uses fifty years of bird-banding data to...

  • Ethnobotanical medicine is effective against the bacterium causing Lyme disease
    (Frontiers) A preclinical in vitro study shows that selected plant-based herbal medicines, especially Ghanaian quinine and Japanese knotweed, work better than antibiotics against the bacterium that causes Lyme disease. These findings represent an important step towards the development of treatments that might be better tolerated and more effective than the... Read more »
  • Sub-Neptune sized planet validated with the habitable-zone planet finder
    (Penn State) A signal originally detected by the Kepler spacecraft has been validated as an exoplanet using the Habitable-zone Planet Finder.... Read more »
  • Physics tool helps track cancer cell diversity
    (Cornell University) A Cornell-led team took a novel, interdisciplinary approach to analyzing the behavior of breast tumor cells by employing a statistical modeling technique more commonly used in physics and economics. The team was able to demonstrate how the diversity, or heterogeneity, of cancer cells can be influenced by their... Read more »
  • How newborn stars prepare for the birth of planets
    (National Radio Astronomy Observatory) An international team of astronomers used two of the most powerful radio telescopes in the world to create more than three hundred images of planet-forming disks around very young stars in the Orion Clouds. These images reveal new details about the birthplaces of planets and the... Read more »
  • Scientists use light to convert fatty acids into alkanes
    (Chinese Academy of Sciences Headquarters) Researchers led by Prof. WANG Feng at the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences have reported that photocatalytic decarboxylation is an efficient alternate pathway for converting biomass-derived fatty acids into alkanes under mild conditions of ambient temperature and pressure....
