New Study

Veritable powerhouses – even without DNA

Parasitic algae from the dinoflagellate lineage have organised their genetic material in an unprecedented way

Whether human beings or animals, plants or algae: the cells of most life forms contain special structures that are responsible for energy production. 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 material, as the team reports…

On Thursday, 18 April 2019 an official groundbreaking ceremony was held for a new Technical Centre for the development of innovative maritime technologies in Klußmannstraße, Bremerhaven. Representatives of the Federal Ministry of Education and Research, the Federal State of Bremen, and the City of Bremerhaven celebrated this milestone together with the Directorate and staff of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research.

Helmholtz program MOSES

Three research vessels – one mission

Research team takes a closer look at extreme high-flow and low-flow events

Wissenschaftler des Helmholtz-Programms MOSES beproben die Nordsee zwischen Cuxhaven/Büsum und Helgoland.
[16. April 2019] 

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. 

New Study

What Earth's gravity reveals about climate change

Researchers take stock of the GRACE satellite mission in Nature Climate Change

[15. April 2019] 

On March 17, 2002, the German-US satellite duo GRACE (Gravity Recovery and Climate Experiment) were launched to map the global gravitational field with unprecedented precision. After all, the mission lasted a good 15 years - more than three times as long as expected. When the two satellites burnt up in the Earth's atmosphere at the end of 2017 and beginning of 2018, respectively, they had recorded the Earth's gravitational field and its changes over time in more than 160 months.
