  • Seabirds are not at risk from offshore wind turbines

    At least according to this survey by Swedish power giant Vattenfall:

    The movements of herring gulls, gannets, kittiwakes, and great black-backed gulls were studied in detail from April to October, when bird activity is at its height. (This study only looked at four bird species, but Vattenfall says the model can and should be applied to more types of seabirds and to onshore wind farms as well.) The study’s findings: Not a single collision between a bird and a rotor blade was recorded.

  • Metformin, a new drug to prevent long covid

    ‘Over a thousand people with mild-to-moderate Covid were randomly assigned to 2 weeks of metformin (500 mg pills, 1 on day 1, twice a day for 4 days, then 500 mg in AM and 1000 mg in PM for 9 days) or placebo. There was a 42% reduction of subsequent Long Covid as you can see by the event curve below, which corresponds to an absolute decrease of 4.3%, from 10.6% reduced to 6.3%.’ Still no use for _treating_ long COVID though.
