German public research university in Bonn, Germany, known for research across natural sciences, economics, and environmental studies.
Megacauda sungei, a mammaliaform from Jurassic China, pushes the bony anatomy of mammal suckling back to nearly 165 million years ago, a Nature study reports. The structures place the groundwork for a defining mammal trait well before the first modern mammals.
Reality
Researchers describing Megacauda sungei in Nature say the half-metre Jurassic swimmer had a throat built for suckling 165 million years ago. That puts the anatomy for milk-feeding earlier than the last common ancestor of all living mammals.

University of Bonn geodesists mapped ocean warming basin by basin and found gaps from climate model simulations in the double-digit percentage range. The comparison covers the recent past, so whether regional projections carry the same error is still untested.

Bonn-led researchers estimate that anti-conservation tweets from Jair Bolsonaro's government added 190 to 1,700 square kilometers of Amazon clearing in 2019. Local fines and bans held steady, so the authors trace the extra clearing to lowered expectations of prosecution.
Reality
University of Bonn economists found that uniform farmland in eastern Germany caused more grassland to go unproductive during the 2018 drought. That makes field layout a drought risk farms can change, though the published summary does not say how big the effect is.

Researchers at Bonn and Manchester Metropolitan measured the shift against a parasite known to push the same animal into the light. There was no caffeine-free tank, so the comparison is one dose against another.

A five-season Atlantic study led from the University of Miami found ECMWF's AI ensemble carrying more tropical cyclogenesis signal at 84 to 120 hours and less at 36 to 48, which makes it guidance rather than a substitute.
