Our paper on Tissue Concepts is finally out in JCompBiomed 🥳: Supervised pre-training of foundation models needs fewer data and less compute/energy to analyze pathology whole-slide images.

Had fun presenting with Carol Geppert at #ecdp2025.
Our poster “Image registration accelerates (pathology) diagnostics” shows that #imageregistration saves one minute (33%) per case in our pilot study!
Could not make it? Have a look the poster s.x91.de/ecdpposter and video s.x91.de/tnvideo

Man muss in der Debatte um die AfD daran erinnern, dass das Grundgesetz nicht irgendeine liberale Verfassung ist. Es ist die Antithese zum NS-Staat. Die Bundesrepublik ist politisch keine ergebnisoffene Veranstaltung. Grundrechte, Demokratie- und Rechtsstaatsprinzip sind dauerhaft festgelegt.

The number of people travelling from Europe to the US in recent weeks has plummeted by as much as 35%, as travellers have cancelled plans in response to Trump’s policies and rhetoric, and horror stories from the border.

Do foundation models in medical imaging see everyone fairly?🤔
Excited to share our new Science Advances paper uncovering & auditing demographic biases of expert-level VLMs, and comparing to board-certified radiologists🧑⚕️

Amerika diskutiert das Ende der Sommerzeit und nicht mal Trump gelingt es (weil die einen Sommer-, die anderen Winterzeit wollen). Aber: Hawaii und Arizona sind schon weiter. Lasst es uns auch so machen: Wenn Schleswig-Holstein bei Winterzeit bleibt, dauert die Zugfahrt Lübeck-Hamburg nur -16 min.

Really disappointed how slowly Europe (especially Germany) is moving these days
Obviously, to compete with US/China on any relevant topic (AI / economy / defense), we need more European integration, joing funding, joint efforts - and much much faster

Approximately 10% of the NIH staff were fired yesterday. Barely anyone outside of the scientific community noticed, and I'd wager a sizeable number of NIH funded PIs have no idea either.
