I understand that the panels are overwhelmed, yet I am not super happy about the idea that this change is applied retrospectively.

My StG2025 got a B. I waited 1.5y already... and now 1y more, I guess🫠😢

France is switching from Microsoft to Linux

"We must become less reliant on American tools and regain control of our digital destiny. We can no longer accept that our data, our infrastructure, our strategic decisions depend on solutions whose rules, pricing, evolution, and risks we do not control."

One of biggest mysteries in biology: how did complex eukaryotic cells evolve from simple microbes? ~1.8 billion years ago, an archaeal cell likely merged with a bacterium to form the first eukaryotic cell, but can we ever find direct evidence of this transformative event? 🦠 🚶‍♂️

A question I get asked all the time by @dev-journal.bsky.social authors "Why does it cost so much to publish a paper?"

We break down the finances and explain where the money goes

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.

“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...
