The mitochondria story connects endosymbiosis, maternal inheritance, oxidative stress, and the evolution of multicellular life. Here's how those threads weave into a single, stranger picture of what you are.

Mitochondrial diseases can be devastating and untreatable. MRT offers a way to break the maternal inheritance chain — but doing so requires making an embryo with genetic material from three individuals, which is where the ethics get complicated.

DNA is the densest information storage medium that exists. One gram holds 215 petabytes. Researchers at Harvard have already written — and read back — a full book encoded in synthetic DNA strands.

Xenobots weren't programmed — they were evolved. A computer tried billions of body-plan configurations using simulated frog skin and cardiac cells, then the winning design was assembled from actual embryonic cells. The result was a millimeter-scale organism with no precedent in evolutionary history.

You can't design a better enzyme from first principles — the chemistry is too complex. Frances Arnold's Nobel-winning insight was to stop designing and start evolving. Directed evolution lets natural selection do the work.

Strip away everything non-essential and what's left? Syn3.0 — Craig Venter's engineered minimal cell — answers that with 473 genes. Alarmingly, about a third of them have no known function.
