How archaea toggle the nitrogen-uptake switch to avoid overeating

By tightly regulating nitrogen uptake, microorganisms avoid overeating nitrogen and thus wasting energy. Scientists from the Max Planck Institute for Marine Microbiology now reveal how some methanogenic archaea manage to ...

How to protect biocatalysts from oxygen

There are high hopes for hydrogen as the key to the energy transition. A specific enzyme group found in algae and in bacteria can produce molecular hydrogen simply by catalyzing protons and electrons. However, the enzyme ...
