Expedition

An international team of young researchers on board the Polarstern

Exploring interactions between the ocean, atmosphere and climate, in theory and practice

[03. June 2019] 

25 young scientists from around the globe are currently taking part in a month-long expedition from the Falkland Islands to Bremerhaven on board the research icebreaker Polarstern as part of a summer school. On the ‘South-North Atlantic Training Transect’ they will gain unique insights into the marine sciences and engage in short projects on interactions between the ocean, atmosphere and climate.


Climate modeling

A warming Arctic produces weather extremes in our latitudes

AWI experts develop a climate model that explains the faltering jet stream

[28. May 2019] 

Using a newly developed climate model, AWI researchers are now able to show that the undulating course of the jet stream in winter and the associated extreme weather conditions, such as cold spells, are a direct result of climate change.


Microbiology of global change

Major questions concerning the role of microscopic life and our future

How microorganisms shape the dynamic evolution of our planet

[15. May 2019] 

"Microbiology of Global Change" is the name of the research field that deals with microbial responses to global warming and pollution. The journal "Nature Reviews Microbiology" asked Antje Boetius according to her assessment.


IPBES-Bericht

Half of the coral reefs have already been lost

AWI expert on the role of marine biodiversity in the IPBES report

[06. May 2019] 

Commentary by marine biologist Julian Gutt: since the changes taking place underwater are far less visible than those on land, it was all the more important that the IPBES pay due attention to the oceans in its Global Assessment report.


New Study

Veritable powerhouses – even without DNA

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

[24. April 2019] 

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 ...
