Random art in my hotel room. You see it too, right? It's not just me?? Or maybe I'm playing this game too much... #shaw

Piece of a modern art picture that to some people might look a little bit like Hornet from the video game Hollow Knight Silksong

Ich habe wirklich lange nachgedacht, aber mir fällt nichts ein. Sobald ich angefangen habe zu studieren, habe ich schnell gesehen, wie es wirklich funktioniert. Nur das Schulsystem hatte mich enttäuscht. Ich war auf einem MINT-Gym und hatte nach dem Abi keine Ahnung, was Wissenschaft wirklich ist.

I will give a guided tour through evolution at the Mega Knowledgecamp 2025! Everyone in the #Saarbrücken area should check it out :) Info and program here: megakc.hacksaar.de

This diagram was heavily inspired by @kurzgesagt.org by the way :)

Today's lecture was about the immune system. For me personally, when I was a student, this was a very dry topic. Now that I am the professor, I tried to make it a bit more colorful :)

In today's lecture, I talked about infectious diseases! I grouped them by their infectious agents: Bacteria Viruses Eukaryotes (fungi, protozoans, animals) 🍄🦠🪱

I found a bee #orchid in the wild! 😲🤓 I've never seen it with my own eyes. Almost surreal to just find it by the side of the path. This orchid smells like female bees. And also kind of looks like a bee! 🐝 So, certain male bees attempt to "cuddle" with the flowers and thus pollinate them :)

Raccoon Origami 🦝 Made from a 25x25 cm square of kami paper, black on one side. Origami used to be one of my hobbies, but I haven't really done it in years. This one turned out decent, I think. Took me about 2 hours. I made it by following instructions from a YouTube video

Butterfly eggs 🦋🥚on a leaf 🌿 We can see the individual cells of the leaf and the cool "exoskeleton" of the eggs that gives them stability. This was taken with a scanning electron microscope :)

The eggs are upright oval shapes with a net-like scaffolding on the outside.

Can I ask, many of these tablets are badly damaged. Do you just fill in the gaps with educated guesses, or how does that work (assuming you don't have several versions of the same text to fill in the gaps)?

The are kept in culture for weeks, actually :D You slice the brain and put the slices in cell culture medium. The damaged cells heal or die and are absorbed by the others. The neurons even continue to grow and form synapses. It's all a bit spooky, I admit

A firework of brain cells 🎆 These are microscopic images of living mouse brain slices 🐁🧠 Some neurons in these slices have been infected with a virus that transfers a gene from a jellyfish to them. Those infected cells are now producing the jellyfish protein that fluoresces (glows when stimulated)

Look! It's Great-grandma! This is a lung fish. It's more closely related to us humans (and all other land vertebrates) than to any other fish, believe it or not. That's because it was a lung fish (so, a common ancestor of us and this fish) that dared to leave the water and evolved to live on land.

transport them up towards our throat. Every time you clear your throat (ahem), the dirt is moved from windpipe to food pipe, to be disposed of and disinfected in the stomach :)

The trachea (windpipe) of a mouse. This windpipe was cut in half, dried, and then imaged with scanning electron microscopy. Ours looks very similar. All those "hairs" are cilia that move back and forth and that constantly filter dust and pathogens out of the air we breath and

Close up of wind pipe cells. Lots of cilia hairs visible

Zooming out. We see more of the cilia. It looks like a long-hair carpet!

Zooming out even further, we see rows of cells making up the inner lining of the wind pipe

Zooming out all the way, we see the wind pipe cut open. Looks like a halved pipe

Our new video is out :) A 13-min video where we go on a guided train ride from the beginning of life to modern day fungi 🍄‍🟫🍄 What are they and what are their mysteries? Are they superior or inferior to animals? Might they have some sort of intelligence? youtu.be/NO-vO6aBrJA?...

Alright, time to start from zero on Bluesky 🥲 Follow for fun and interesting science content from a biology professor and YouTuber :D My defining traits: positive and enthusiastic, bow tie, loves to tell stories, nerdy, eats too much sugar (but I won't post about that)
