Wondering about the "signature of life" found beyond our Solar System? I wrote a thread for the Carl Sagan Institute critiquing the evidence for exoplanet K2-18 b:
Has JWST found life on another world? 🔭

An analysis of exoplanet K2-18 b points to the existence of dimethyl sulfide, a molecule produced by photosynthesizing plankton on Earth—but proving that this sign is real, and that life is the only explanation, is a difficult task.

Proverbs from ancient Mesopotamia are full of wisdom and humour. Keeping in mind that proverbs helped students practice the Sumerian language at school, it’s a reminder that teachers might have used humour to make lessons more memorable.
