Plastic pollution harms bees: risks for global food security

A new review study is the first to systematically show the harmful effects of nano- and microplastics on bees and other beneficial insects

22-Oct-2024 - Nano- and microplastic particles (NMP) are increasingly polluting urban and rural landscapes, where bees and other beneficial insects come into contact with them. If insects ingest plastic particles from food or the air, it can damage their organs and cause changes in their behaviour, preventing ...

How blue-green algae manipulate microorganisms

Research team discovers previously unknown gene that indirectly promotes photosynthesis

16-Apr-2024 - Cyanobacteria – also called blue-green algae – are known as the “plants of the ocean” because they carry out photosynthesis on a gigantic scale, produce oxygen and extract the greenhouse gas CO2 from the environment. However, to do this they need additional nutrients such as nitrogen. A team ...

Accurate data on dynamic molecular aggregates in cells for the first time

Using a newly developed microscopy method, researchers have for the first time been able to quantify small, dynamic molecular aggregates in living cells that play an important role in signal processing

17-Aug-2023 - In cells, many vital processes take place in membrane-free molecular aggregates. Such aggregates ensure that the molecules involved are present in the right concentration and proximity to each other. Researchers from the Cluster of Excellence CIBSS at the University of Freiburg and the University ...
