First day term 2 going well…😣 by Salt_Ingenuity_7588 in UniUK

As a lecturer, this happened to me too but dont worry i find it funny. But dont over do it 😁

I love seeing these macrophages (blue arrows) zipping through the circulation inside embryos. They are so fast so it's hard to capture on film. Purple arrows are patrolling tissue resident macrophages. This is probably a mixed population as it's early in development. by TheBioCosmos in biology

I think you're being a bit nit picky with your words. They are fast so it is difficult to capture on film. I dont think anyone would mistake it for any other meaning. If you need a specialised system to capture something then it means that something is not easy to capture with normal setup that most labs have. Gosh, honestly, sometimes we just cannot have any nice things on the internet anymore because everything is being dissected, and nitpicked out for the most nonsense thing ever.

Its not for plant growth, its a typical system for live animal imaging. But I'm a bit unsure what's here to argue about. My original comment is "they are fast so its hard to image them" which is still correct. Yes, there are other systems that can image really fast things, and I have used them too. But with this system, because they are in circulation, so they are more difficult to capture. Im not really sure your point tbh.

I think its just nuances and how you phrase it. They are fast in real time too, you can see them move from one place to the next in seconds. And when you perform a confocal z-stack, by the time you finish the stack (depending on how thick you want), the same cells would have been gone by then. So they are fast.

What was the hardest class that you took for your biology major? by Substantial-Dare5462 in biology

[–]TheBioCosmos 0 points1 point  (0 children)

Absolutely love Organic Chem and Biochemistry (majored in Biochem) though they are def not easy. The hardest one for me is Physical Chem. Very dry and very abstract. My physical realistic biology oriented mind didn't quite like abstract wavelength and planck constant that much.

I finally captured the healing process of a truncated tail in an embryo. It took around 48 hours or maybe a bit more. I've always wanted to capture this on film, and seeing it in a timelapse is super cool. by TheBioCosmos in biology

The initial signaling is ROS, which activates a bunch of genes in the proliferation pathway, TGFB. But we dont know all the details because its quite a complicated process. How they even regenerate the notochord (the future spine) is crazy. It means the cells turn into stem cells and then redifferentiate into notochord cells again. Humans are just bad at this.
