  • Breaking the chain

    The fight against climate change is a call-to-arms for industry. We currently rely on fossil fuels, a major source of the greenhouse gas CO2 , not only for energy but also to create chemicals for manufacturing. To ween our economies off this dependency, we must find a new source of "green" raw mater more

  • Drinking glasses can contain potentially harmful levels of lead and cadmium

    Enamelled drinking glasses and popular merchandise can contain potentially toxic levels of lead and cadmium, a study has shown. Researchers at the University of Plymouth carried out 197 tests on 72 new and second-hand drinking glass products, including tumblers, beer and wine glasses, and jars. They more

  • Primordial black holes may have helped to forge heavy elements

    Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis. As the late Carl Sagan once put it: "The nitrogen in our DNA, the calcium in our teeth, the iron in our b more
