  • What caused the most toxic algal bloom ever observed in Monterey Bay?
    on June 5, 2017 at 7:02 pm

    In spring 2015, the West Coast of North America experienced one of the most toxic algal blooms on record. The bloom consisted of diatoms in the genus Pseudo-nitzschia, but researchers couldn't tell why these algae had become so toxic. A new article shows that, at least in Monterey Bay, this bloom became particularly toxic because of an unusually low ratio of silicate to nitrate in the waters of the bay. […]

  • Metal-ion catalysts and hydrogen peroxide could green up plastics production
    on June 5, 2017 at 4:41 pm

    Researchers are contributing to the development of more environmentally friendly catalysts for the production of plastic and resin precursors that are often derived from fossil fuels. The key to their technique comes from recognizing the unique physical and chemical properties of certain metals and how they react with hydrogen peroxide. […]

  • Splitting carbon dioxide using low-cost catalyst materials
    on June 5, 2017 at 3:08 pm

    A promising avenue for the future of clean energy is to store it in the form of carbon-based fuels produced from renewable sources, effectively enabling the clean use of liquid fuels such as gasoline. A first step is the electrolysis of carbon dioxide into oxygen and carbon monoxide. But current CO-forming catalysts are either not selective enough or too expensive to be industrially viable. Now scientists have developed an Earth-abundant catalyst based on copper-oxide nanowires modified with tin oxide. […]

  • How exactly does water get to homes?
    on May 31, 2017 at 5:32 pm

  • Earth's atmosphere more chemically reactive in cold climates
    on May 17, 2017 at 5:26 pm

    A Greenland ice core providing a first glimpse at the history of reactive oxidants shows that for big temperature swings in the past 100,000 years, reactive oxidants are actually higher in cold climates. This means that new mechanisms -- not just water vapor, plant and soil emissions -- must affect the concentration of ozone and other oxidants in the atmosphere. […]
