A few days after successfully defending my PhD, another chapter of my thesis is out in Environmental Toxicology!🥳 Here, we show that bird embryos actively mobilize Hg from eggshells, key for better understanding Hg impact on wildlife. More information can be found here👇 doi.org/10.1002/tox....

Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism
Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via matern...

Look who arrived as well! 147 little field assistants made their way into one of our incubators. These laboratory-bred kissing bugs will help us collect blood samples from incubating terns. Stored in a fake egg for c. 20 minutes, they collect blood, which we then gratefully collect from them.

“we are trapping 21st-century minds inside 19th-century academic hierarchies.” This essay gets a lot right about problems with German science. I would add that the hierarchies and precarious contracts lead also to systemic abuse and scientific misconduct. open.substack.com/pub/realimag...
Germany does not lack talent, and it does not lack funding. But we are trapping 21st-century minds inside 19th-century academic hierarchies. We are asking brilliant young scientists to build the future of the German economy, but refusing to give them the lab space, the job security, or the scientific independence to actually do it. If we want to reclaim our place as an industrial superpower, we have to stop the rat race of trying to keep every technology and structure alive that made us successful in the 20th century. Instead, we must fix our system that pushes our most ambitious scientists away. The money is there. The talent can be there. Now, we also need the courage to fix what’s broken.
