In remembrance of Peer Bork  | EMBL EMBL and its community are deeply saddened by the death of Peer Bork, the organisation’s Interim Director General.

very sad news. Peer Bork was one of the leaders of our field, a wonderful scientist, and he's much too young to be gone. www.embl.org/news/embl-an...

Excited to share our new @natecoevo.nature.com
paper. We identified microbes found across nearly all ruminants that act as the functional backbone of both the rumen ecosystem and the host, with major implications for food security and climate change mitigation. (1/8)

Widespread potential for phototrophy and convergent reduction of lifecycle complexity in the dimorphic order Caulobacterales - Nature Communications This study maps out the diversity and evolution of the bacterial order Caulobacterales, including the model organism C. crescentus, which reveals widespread phototrophy and illuminates the evolution o...

Excited to see our new work published! We have established the evolutionary and ecological context of our favorite model Caulobacter and made some unexpected findings.
Who would have thought that close relatives lack dimorphism? And have potential for phototrophy?

Two full-time positions | Bioinformatician (m/f/d) + Applications Specialist (m/f/d) - Molecular Biology The Genome Facility at the Max Planck Institute for Evolutionary Biology in Plön is seeking to fill two positions (full time) to support and expand our core facility services.

Two new positions are available at the MPI for Evolutionary Biology to support development of our genomics facility. Both stand to become permanent. Both offer a ton of opportunity to engage in a wide range of creative science.

Metabolic interplay drives population cycles in a cross-feeding microbial community - Nature Communications Here the authors leverage a crossfeeding, engineered microbial community to demonstrate that strain abundance cycles are robust across environmental conditions. They pair this with a nonlinear dynamic model to elucidate population cycles.
