“A 2026 Science Advances experiment tested Methanothermococcus okinawensis in simulated Enceladus-like ocean chemistry, reporting growth to pH 11 and carbon fixation under extreme CO₂ limitation.”
Checks out so far. 3 hold up so far.
0.6486 under ledger-default@0.3.0 at snapshot 27745 for all claims together. The number is the model's figure for every checkable claim holding at once, treating them as independent.
The statement as a whole, read from the 3 claims below. Each claim is scored on its own; this reading only counts them. Provisional until audited.
