AI Thread Summary
The discussion focuses on the need for an advanced online resource that explains the process of taking a DNA sample from body cells. The inquiry seeks clarification on whether the interest lies in the collection method of the sample itself or in the subsequent extraction and purification techniques for DNA analysis. This distinction is crucial for identifying the appropriate sources that provide detailed and technical information on the subject.

This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
