@danielheringude.bsky.social, I read your posts, but I agree to wish more interactions here. Maybe that's the price for a more polite community here. People who prefer reading over nonsense comments.

How to stop the revolving door of German academia Germany is one of the most popular destinations for students and scholars worldwide, but those pursuing academic careers face significant hurdles to success.

The situation of postdocs in Germany has made it to Nature: www.nature.com/articles/d41...

The lecture series offers insights into current research projects and shows how cross-border cooperation works in science and in practice: monitoring of watercourses, quality of wastewater treatment, aquatic biodiversity,
stream restoration, sustainable use of water systems in European cities.

Florian Altermatt and a slide with his proposed pipeline.

Fascinating an motivating plenary talk from @florianaltermatt.bsky.social at #DGL2025. He made a strong plea for rethinking the way we use eDNA to monitor aquatic biodiversity. Inspired me to read more about his research.

Alt text: A vibrant, stylized nighttime cityscape symbolizing Warsaw, Poland, host of the UseR! 2026 Conference. A glowing river winds through the city, bordered by illuminated buildings that blend modern skyscrapers with traditional European architecture. The deep blue sky sparkles with stars and celestial bodies, and a large moon-like orb at the center displays a bold letter "R"—a nod to the R programming language, widely used for statistical computing, data analysis, and visualization. The image’s rich blues and warm yellows evoke both innovation and cultural heritage. The UseR! Conference series is the premier international gathering for R users and developers, fostering collaboration, sharing cutting-edge research, and promoting open-source tools. This artistic depiction captures the excitement and creativity of the global R community coming together in Warsaw for learning, networking, and advancing data science.

Bade-Dermatitis durch Zerkarien: Rote Flecken nach dem Baden durch Entenwürmer | MDR.DE Wer nach einem Bad in einem See rote Flecken oder Quaddeln auf der Haut findet, könnte sich die "Enten-Dermatitis" eingefangen haben. Der Ausschlag ist unangenehm, aber in der Regel nicht gefährlich.

"Enten-Dermatitis": Zerkarien in Seen können roten Ausschlag nach dem Baden verursachen. 🏊 Hydrobiologe Thomas Berendonk von der #TUDresden erklärt bei MDR Wissen, wo die Gefahr dafür am größten ist & warum der Ausschlag in der Regel unbedenklich ist.
