Sequencing my own DNA at home

Bradley Woolf sent a note about sequencing his own DNA at home — the kind of thing that would've cost a fortune five years ago and now reads like a weekend project. The linked guide walks through the basics: cells, genomes, DNA, chromosomes, the whole biological stack. It's a primer, not a research paper, but it's the kind of background anyone needs before buying a kit off the shelf.

What makes this interesting isn't the kit itself — it's the shift. Genomics is moving from the lab bench to the kitchen counter. You don't need a research grant or a PhD anymore; you need $200 and the patience to follow instructions. That matters because the people writing about this are often folks who've never had to explain what a genome is to their abuela, and they're doing it in plain language so the rest of us can actually use it.

Why this matters for us: as personal genomics goes mainstream, the tools and the data are going to touch our families, our health decisions, and how we understand ourselves — so knowing the basics before a company or a clinic tries to sell you something you don't understand is a real advantage.
