TL;DR

- K2-18b

- detected dimethyl sulfide and dimethyl disulfide, false positive possibility is now very low

- "produced by marine-dwelling organisms on Earth", possibility they were produced by other processes (unrelated to life as we know it) not high but maybe unknown unknowns

- other factors like distance from the star are in favor of life & water

- previous studies detected methane and carbon dioxide
