If forest lizards are exposed to high temperatures, their chromosome ends shrink faster. This affects your life expectancy - and the inventory of local populations.

"The dimensions of the fish death are huge"

The death of fish in the Oder has reached the Baltic Sea coast. The cause is unclear. Water expert Sascha Maier explains in an interview how the river can now be protected.

Curfew for domestic cats ends prematurely
