tldw: scientists try to match absorption spectra of 20 molecules to exoplanet transit curve; one of them (DMS) matches to 2σ; scientists publish paper "hint of DMS found!"; university published press release "biosignature found!"; news media report "extraterrestrial life found!"
So basically the xkcd jellybeans situation: https://xkcd.com/882/
(2σ = 95% confidence interval = 1-in-20 false positive)
