Referred to as mitochondria, they normally have their own genetic material, in addition to that found in the nucleus. Uwe John and colleagues at the Alfred Wegener Institute have now identified the first-ever exception to this rule in a single-celled parasite. The mitochondria of the dinoflagellate Amoebophrya ceratii appear to produce energy just like our own mitochondria, but without any genetic ...

Based on global forecasts, storm events accompanied by heavy rainfall and flooding will occur 10 to 20 percent more frequently by the end of this century. Moreover, they and extreme low-water phases will produce a tremendous amount of damage, not to mention both socio-economic and ecological impacts. In order to better understand those impacts, on 16 and 17 April 2019 three research ships in the Helmholtz programme MOSES will undertake a joint research cruise from the Elbe estuary to Helgoland.
