In Paris, districts with more vegetation have a lower risk of death during periods of high heat, while highly mineralized areas with few green spaces and a high potential for urban heat islands are the most exposed.

At the Bromacker fossil site in Germany, an international team including a CNRS scientist 1 has identified the oldest terrestrial fossilised vomit known so far. Dated to around 290 million years ago (Early Permian), several tens of millions of years before dinosaurs appeared, this fossilised vomit, or "regurgitalite," contains numerous partially digested bone fragments, including those of two small reptiles and an amphibian 2 , preserved in a phosphate-poor matrix 3 .

Documented for 200 years, the Iguanodontia group is expanding with the discovery of a brand-new species, the first known to bear spikes with properties never before observed in dinosaurs.

An experimental study conducted under semi-natural conditions shows that pesticide mixtures present in agricultural landscapes significantly affect the health of grey partridges.
