I was reviewing wound healing by watching youtube lectures on it and I stumbled across this video of fibroblasts doing their thaaaang. Cool beans. I love it! I’ve never seen these things in action before!
So, in a very big nutshell, if you’re not sure what fibroblasts are, they build collagen fibers. Collagen fibers are incredibly strong connective fibers that hold things together. So when you cut yourself, a lot of things happen to repair it as quickly and efficiently as possible - fibroblasts rushing to the scene to build a new matrix to help repair the damaged tissue is one of those things. They also help pull the wound together, making it easier for the cells to grow back together.
That’s my medical tumblr but I mainly post anatomy and microbiology stuff
I can only hope that one day, when we explore the oceans of the solar system (e.g. Europa, Ceres, Enceladus, etc.) we stumble across something bizarre like siphonophores.

These are glowing gases which are emissions from dying red giants. When the red giant dies, it just keeps expanding and dissipates into these beautiful space clouds. Typically, there’s a little white dot in the middle and this is usually a white dwarf, the leftover core of the star.
When viewing these beauties though x-ray filters, they can be quite astounding
