I want to thank my co-first authors Katja von Hoff and Denise Obrecht-Sturm, the supervisors of this study, Kristian Pajtler and Stefan Rutkowski, and of course all other co-authors and especially our patients and their families. There is still a lot of work ahead of us! 3/3

By incorporating molecular and clinical risk factors into one stratification model, we anticipate that our work will help to design the next generation of ependymoma trials. This was a complex and long-lasting, but also very rewarding project. 2/3

Our free webinars are back!

Today we had the pleasure of listening to Dr Ulrich SchΓΌller from the Research Institute Children’s Cancer Center Hamburg, talking about his work on the molecular diversity of spinal ependymomas.

Achievements such as this would have been thought of as impossible only a couple of decades ago. #Science delivers. But in a world where scientists are attacked, drowned in bureaucracy and regulations, and cut off their funding, miracles like the cure of #SMA will become rare.

Ever wondered how different biological datasets can be combined in the best way (e.g. data from #transcriptomics #proteomics #DNAmethylomics)?

Have a look at our #review paper describing challenges of #data integration and available #algorithms and tools.

Gene editing technology began by people studying salt marshes. Ozempic began by folks studying the venom of Gila Monsters. Support for basic science has empowered us to understand our world. Tethering it to applications health has transformed and saved countless lives.

Hey there! As always somewhat late to the latest social network party, but let's see whether bluesky has indeed become science twitter from a couple of years ago. Looking forward to meeting many new and familiar friends and colleagues here!
