The hidden danger of oxygen

https://www.mpg.de/1170854/pollen_allergy

New findings from researchers at the Max Planck Institute for Chemistry and the Paul Scherrer Institute in Switzerland help to explain how toxic and allergy-causing substances in our air are formed. The scientists have for the first time detected long lived reactive oxygen intermediates on the surface of aerosol particles. These forms of oxygen survive here for more than 100 seconds and in that time react with other air pollutants such as nitrogen oxides. Chemically speaking, the dust particles are oxidized and nitrated. This is what makes soot particles more toxic and increases the potential of pollen to cause allergies.

How sticklebacks adapt to new habitats

https://www.mpg.de/17386061/sticklebacks-evolution-adaptation?c=12640851

Three-spined sticklebacks live in both salt and fresh water. When the glaciers melted at the end of the last ice age and new lakes were formed, sticklebacks from the sea found new habitats in them. Felicity Jones and her team at the Friedrich Miescher Laboratory of the Max Planck Society in Tübingen are investigating how the genome of the fish changes in the course of adaptation. 12,000-year-old stickleback bones provide insights into the early stages of this process.
