Study in mice finds certain gut microbes can attack long-chain PFAs (take longer to dispel naturally), taking them out of your body. "Among the most common and dangerous long chains are Pfoa and Pfna, which the microbes expelled at rates of up to 58% and 74%, respectively." Study in humans next. It can take decades for the body to fully expel PFAs naturally. #Forever #Chemicals #PFAs #no #side #effects #gut #microbes #long #short #chain #expel #micro #plastics theguardian.com/environment/20

The Guardian · Some gut microbes can absorb and help expel ‘forever chemicals’ from the body, research showsBy Tom Perkins
C.

This will be slightly #geeky, and probably only of interest to #electronics hobbyists and #guitar players. I happen to sit in the intersection of that particular #Venn diagram.

When I was a teenager, having only been playing guitar for a few years, I owned a guitar #effects pedal that went on to become legendary - the Boss HM-2 "Heavy Metal" #pedal. Its sound is still ubiquitous in metal.

I don't have it any more. I think I traded it for an analog chorus, which was a seriously expensive pedal back then. Although I have other #distortion effects, I've missed it a lot over the years.

Well, lots of hobbyists build their own effects. And the circuit schematics for many effects, particularly the classics, are available online. So like many others, I decided to build my own HM-2.

This image is the schematic for the #HM2. It's not the most complicated pedal, but it's a league above something like an Ibanez Tube Screamer. As far as active devices go, it's got 6 #opamps and 10 #transistors of various types, along with a bunch of diodes for multiple types and stages of clipping, and the usual jumble of capacitors and resistors. Oh, and four potentiometers.
