  • I think the argument here is that you are going to have to draw the line somewhere. Instead of replicating every experiment yourself, you’re just going to have to take someone’s word for it.

    You may trust a particular scientist, publication, journal, school book or another source. You may believe that what they say is reliable and… well true? Or maybe you believe it’s close enough, or at least it’s the best info we have at the moment, but who knows if it’s actually true or not. Either way, people choose to believe something about these sources, because you have to draw the line somewhere.











  • Microbiology can be so much fun!

    Streptococcus pyogenes causes a flesh-eating disease (necrotizing fasciitis). This species of bacteria releases toxins that kill living tissue, so you better make sure that paper cut doesn’t get infected.

    Mycobacterium tuberculosis is famous for a bunch of different pandemics over the centuries. If you thought covid was fun, imagine coughing up blood.

    Clostridium botulinum is special, because it produces a very spicy toxin, so you don’t even have to ingest any living cells or spores of C. botulinum to get killed by it. If you do, you can even have your very own toxin factory inside you.

    Vibrio cholerae is another classic responsible for numerous pandemics. This one is a bit different, because it involves lethal amounts of diarrhea.

    Oh, and the scary bit? There are people who don’t believe bacteria or viruses exist. They actively oppose taking measures against these things. Humans can be truly horrifying at times.
