  • Changes in Hudson River may offer insight into how glaciers grew
    Researchers say they may be able to estimate how glaciers moved by examining how the weight of the ice sheet altered topography and led to changes in the course of the river.... Read more »
  • Better methods improve measurements of recreational water quality
    The concentration of enterococci, bacteria that thrive in feces, has long been the federal standard for determining water quality. Researchers have now shown that the greatest influences on that concentration are the quantity of mammalian feces in the water, and the numbers of enterococci that glom onto floating particulate matter....

  • Allergy potential of strawberries and tomatoes depends on the variety
    Strawberries and tomatoes are among the most widely consumed fruits and vegetables worldwide. However, many people are allergic to them, especially if they have been diagnosed with birch pollen allergy. A team has investigated which strawberry or tomato varieties contain fewer allergens than others and to what extent cultivation or... Read more »
  • 84 highly endangered amur leopards remain in China and Russia
    Scientists estimate there are only 84 remaining highly endangered Amur leopards (Panthera pardus orientalis) remaining in the wild across its current range along the southernmost border of Primorskii Province in Russia and Jilin Province of China.... Read more »
  • Growing a dinosaur's dinner
    Scientists have measured the nutritional value of herbivore dinosaurs' diet by growing their food in atmospheric conditions similar to those found roughly 150 million years ago.... Read more »
  • Study describes enzyme's key role in immune response to Chagas disease parasite
    (Fundação de Amparo à Pesquisa do Estado de São Paulo) A study shows that the expression of PI3Kγ protein increases during infection by T. cruzi, an essential response in avoiding excessive inflammation and controlling parasitemia. Heart tissue analyses involving human patients who developed cardiopathy in the disease's chronic stage also... Read more »
  • Keeping kidney stones at bay during space flights
    (University of Washington Health Sciences/UW Medicine) Ultrasonic repositioning of kidney stones will be tested in emergency department patients at UW Medicine as part of the development of a new medical technology for NASA. Astronauts are prone to kidney stones during space missions. The hope is that pushing stones... Read more »
  • Barium ruthenate: A high-yield, easy-to-handle perovskite catalyst for the oxidation of sulfides
    (Tokyo Institute of Technology) Researchers at Tokyo Institute of Technology have developed a ruthenium-based perovskite catalyst that shows strong activity even at low temperatures (down to 313 K). The reusable catalyst does not require additives, meaning that it can prevent the formation of toxic by-products. The oxidation of sulfides is... Read more »
  • Seth Davidovits wins 2018 Marshall N. Rosenbluth dissertation award
    (DOE/Princeton Plasma Physics Laboratory) Seth Davidovits, a 2017 graduate of the Program in Plasma Physics in the Princeton University Department of Astrophysical Sciences, has won the 2018 Marshall N. Rosenbluth Outstanding Doctoral Thesis Award presented by the American Physical Society.... Read more »
  • Products of omega-3 fatty acid metabolism may have anticancer effects, study shows
    (University of Illinois at Urbana-Champaign) A class of molecules formed when the body metabolizes omega-3 fatty acids could inhibit cancer's growth and spread, University of Illinois researchers report in a new study in mice. In mice with tumors of osteosarcoma - a bone cancer that is notoriously painful and difficult... Read more »
