  • Researchers find an alternative mode of bacterial quorum sensing
    on August 21, 2017 at 7:51 pm

    Whether growing in a puddle of dirty water or inside the human body, large groups of bacteria must coordinate their behavior to perform essential tasks that they would not be able to carry out individually. Bacteria achieve this coordination through a process called quorum sensing in which the microorganisms produce and secrete small molecules called autoinducers that can be detected by neighboring bacterial cells. Only when a large number of bacteria are present can the levels of secreted autoinducer build up to the point where the community can detect them and respond as a coordinated group. […]

  • Clean energy scores a small victory
    on August 21, 2017 at 7:40 pm

    Government scientists worried that their long-in-the-works assessment of climate change would be suppressed. The concern hardly rates as overwrought. Scott Pruitt, the head of the Environmental Protection Agency, says he does not believe that carbon dioxide is a primary contributor to global warming. President Donald Trump has called the concept a hoax pushed by the Chinese. (Or maybe he was joking?) […]
