  • Flooding damage to levees is cumulative -- and often invisible
    Recent research finds that repeated flooding events have a cumulative effect on the structural integrity of earthen levees, suggesting that the increase in extreme weather events associated with climate change could pose significant challenges for the nation's aging levee system.... Read more »
  • New species of antibiotic-resistant bacteria found in infected wound
    A hitherto unknown antibiotic-resistant bacteria species, in the same family as E. coli and Salmonella spp., has been found and classified in Sweden. The proposed taxonomic name of the species -- the first of the new genus -- is Scandinavium goeteborgense, after the city of Gothenburg, Sweden, where the bacterium... Read more »
  • Insect bites and warmer climate means double-trouble for plants
    Scientists think that current models are incomplete and that we may be underestimating crop losses. A new study shows that infested tomato plants, in their efforts to fight off caterpillars, don't adapt well to rising temperatures. This double-edged sword worsens their productivity.... Read more »
  • Walking sharks discovered in the tropics
    Four new species of tropical sharks that use their fins to walk are causing a stir in waters off northern Australia and New Guinea.... Read more »
  • Well-designed substrates make large single crystal bi-/tri-layer graphene possible
    Scientists have reported the fabrication and use of single crystal copper-nickel alloy foil substrates for the growth of large-area, single crystal bilayer and trilayer graphene films.... Read more »
  • Mason researchers Narayanan and Veneziano receive funding to build better vaccines
    (George Mason University) George Mason University's Aarthi Narayanan and Remi Veneziano received $314,000 from US Army Medical Research Acquisition Activity (USAMRAA) for a project using DNA-nanoparticles to improve vaccine design. The new design uses one-, two-, and three-dimensional structures made out of DNA molecules to increase immunogenic potential by delivering... Read more »
  • Study: Pharmaceutical companies marketing stimulants to physicians
    (Boston Medical Center) Results of a new study show that a large number of physicians in the US may have received marketing payments from pharmaceutical companies that produce stimulant medications. Led by researchers at Boston Medical Center's (BMC) Grayken Center for Addiction, the first of its kind study found that... Read more »
  • Coral 'helper' stays robust under ocean acidification
    (ARC Centre of Excellence for Coral Reef Studies) A type of algae crucial to the survival of coral reefs may be able to resist the impacts of ocean acidification caused by climate change. In a world-first, scientists discover coralline algae are able to build tolerance over multiple generations.... Read more »
  • Determining the atomic structure of natural products more rapidly and accurately
    (Forschungsverbund Berlin) Many drugs are derived from natural products. But before natural products can be exploited, chemists must first determine their structure and stereochemistry. This can be a major challenge, particularly when the molecules cannot be crystallized and contain only few hydrogen atoms. A new NMR-based method, developed at the... Read more »
  • UMMS scientist shows gene therapy protection of eyesight in models of multiple sclerosis
    (University of Massachusetts Medical School) Research from the University of Massachusetts Medical School, reveals the molecular process in which synaptic connections in the brain are damaged in multiple sclerosis and how this contributes to neurodegenerative symptoms. The paper, published in Immunity, also shows how gene therapy may be used to... Read more »
