This will be the last iteration of my experiments with Aspen. I didn't have any issues so far, so I hope this new generation will be well-behaved like the previous ones.

It is a pleasure to join the UPSC community and begin this new chapter. I’m excited for the years ahead and grateful for the opportunity to work alongside such inspiring colleagues. Many thanks to Anne Honsel for this beautifully written research portrait.

Just arrived to Heidelberg for the symposium on "Mechanobiology accross the tree of life" #EESMechanobiology I have polished a bit my story on wood cell fate and biomechanics, my first time with a black background poster. Very excited to share and learn!!

In our #featuredimage post, we are branching out into AFM with an image showing surface stiffness of an Arabidopsis thaliana hypocotyl from Emily Oren @slcuplants.bsky.social. Check out our post to discover more about the image and Emily's research: focalplane.biologists.com/2026/04/10/f...
Our featured image, acquired by Emily Oren, shows the surface stiffness of an Arabidopsis thaliana hypocotyl. It was acquired using a Bruker Biowizard 5 Atomic Force Microscope (AFM) and is of plasmolysed epidermal cells on a live seedling. In this image, brighter colours correspond with a higher Young’s Modulus. The stiff anticlinal cell walls are clearly visible, as well as the distinctive stiffness pattern of the guard cells surrounding the stomatal pore.

Geneticists challenge theory of how cells retain their identity
In Science Advances, the results are presented that open the door to rewriting a chapter of cell biology.

Working prototype of a heating/cooling modular algae photobioreactor with built in bubbler, multispectral sensor, and grow light. No custom PCB's. All off the shelf parts. Simple arduino code. Open source. This one's for @kylelauersen.bsky.social. I love making lab hardware. #scisky

Welcome to the #devbiolwriteclub Bluesky Boot Camp! I’ll be posting here regularly with thoughts and exercises to help scientists become better writers. Let’s start by managing expectations: I will NOT help you write better. I WILL help you become a better writer. 🧵 1/10
