  • The Secret Contamination of Polar Bears

    Using a new approach to measure chemical contaminants in polar bears, scientists from Canada and the United States found a large variety of new chlorinated and fluorinated substances, including many new polychlorinated biphenyl metabolites. Worryingly, these previously unrecognized contaminants have more

  • Crystals that clean natural gas

    Removing the troublesome impurities of hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas could become simpler and more effective using a metal-organic framework (MOF) developed at KAUST. Upgrading natural gas in this way could help Saudi Arabia to make greater and cleaner use of its a more

  • System selectively sequesters toxins from water

    Rice University scientists are developing technology to remove contaminants from water - but only as many as necessary. The Rice lab of engineer Qilin Li is building a treatment system that can be tuned to selectively pull toxins from drinking water and wastewater from factories, sewage systems and more
