    Discussion Feel free to provide feedback for a new logo

    After lots of prompting, I finally got ChatGPT to make some decent images of a petri dish, shaped like a speech bubble, with a colon speckled with microbes inside. I added them to the OP. I'm not too sure where to use them, or if I want to use them. Maybe in place of the "HM" favicon.

    Suppose that the gut/brain axis is as important (in psychiatry) as the peer-reviewed literature seems to indicate. Why then isn't fecal transplantation an extremely famous and celebrated psychiatric treatment?

    I describe it as "disruption" in my probiotic guide. I experienced something similar with olive oil.

    You're welcome to try it and report your results. I wouldn't try it myself due to concerns about donor quality.

    Other What exactly is forbidden in the US with regards to FMT?

    The "paying so much" was due to the inability to recruit effective donors. Removing all mention of FMT and making it unclear what we want their poop for would only make things exponentially more difficult.

    Other What exactly is forbidden in the US with regards to FMT?

    You cannot prescribe unapproved drugs. Doctors need an IND if they want to try FMT on a patient. You can see the exact issues in the FDA warning letter: https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/warning-letters/human-microbes-672740-02092024 The primary...

    Ok, here's the plan: I don't think it's going to be useful to tweet at (& like) famous people unless you have hundreds of people participating. If you can find smaller targets that are more likely to pay attention to a tweet with a handful of likes, we can try it. I plan to start recording...
