  • Common weed killer linked to bee deaths
    on September 24, 2018 at 9:45 pm

    Honey bees exposed to glyphosate, the active ingredient in Roundup, lose some of the beneficial bacteria in their guts and are more susceptible to infection and death from harmful bacteria. Scientists believe this is evidence that glyphosate might be contributing to the decline of honey bees and native bees around the world. […]

  • Anti-inflammatory protein promotes healthy gut bacteria to curb obesity
    on September 19, 2018 at 5:36 pm

    Scientists have discovered that the anti-inflammatory protein NLRP12 normally helps protect mice against obesity and insulin resistance when they are fed a high-fat diet. The researchers also reported that the NLRP12 gene is underactive in people who are obese, making it a potential therapeutic target for treating obesity and diabetes, both of which are risk factors for cardiovascular disease and other serious conditions. […]

  • Microbubble scrubber destroys dangerous biofilms
    on September 19, 2018 at 5:30 pm

    Stiff microbial films often coat medical devices, household items and infrastructure such as the inside of water supply pipes, and can lead to dangerous infections. Researchers have developed a system that harnesses the power of bubbles to propel tiny particles through the surfaces of these tough films and deliver an antiseptic deathblow to the microbes living inside.

  • Dietary fiber reduces brain inflammation during aging
    on September 14, 2018 at 12:48 pm

    As mammals age, immune cells in the brain known as microglia become chronically inflamed. In this state, they produce chemicals known to impair cognitive and motor function. That's one explanation for why memory fades and other brain functions decline during old age. But, according to a new study, there may be a remedy to delay the inevitable: dietary fiber. […]
