Justyna Wolinska's team has studied the effect of polystyrene nanoparticles on parasite-host interactions. Two studies show that nanoplastics can change the outcomes of a disease.

Microorganisms help to keep the water of lakes clean. In the process, they also detoxify the nitrogen compound ammonium, which is introduced into water bodies by fertilizers, for example, and is also produced naturally by metabolic processes. An international team led by the German Collection of Microorganisms and Cell Cultures (DSMZ) with IGB researchers Hans-Peter Grossart and Danny Ionescu has now shown that this detoxification of ammonium in the depths of European lakes is only sustained by an extremely small number of specific archaebacteria species.

Happy Birthday LakeLab! For a decade now, IGB has been conducting large-scale experiments on the impacts of climate change and other anthropogenic environmental changes on lake ecosystems at the IGB LakeLab in Lake Stechlin. In this brief interim account, we present the projects, scientific findings and new perspectives that have emerged from research conducted in the facility so far. It is a journey through time on the occasion of the first big anniversary.

IGB has provided feedback on the government draft of the National Water Strategy, emphasising, among other things, the relevance of aquatic biodiversity and the large practical implementation deficit in water management.

No life has yet been found on Mars, but it is exciting to explore under what circumstances it might be possible. A team has studied the cellular processes that regulate the adaptation of microorganisms to perchlorates. If microorganisms could genetically adapt their stress response to this salt, which occurs in some deserts and on Mars, their survival on the red planet would be possible.

Today, the second part of the UN Biodiversity Conference (CBD COP 15) starts in Montreal. In previous negotiations, inland waters have not been given sufficient consideration – even though they harbour a particularly high biodiversity and provide vital ecosystem services for humans. IGB scientists researching freshwater biodiversity provide an overview of this often overlooked topic.

Researchers from IGB and the Adam Mickiewicz University (AMU) in Poznań (Poland) tested whether water fleas (Daphnia) are more frequently infected by the parasite Caullerya mesnili in warmer waters. For the infected water fleas, the disease usually ends fatally.

Long thought to rely solely on photosynthesis, the microbe Prochlorococcus may get as much as one-third of its carbon through a second strategy: consuming the dissolved remains of other dead microbes.
