We possess the technology to create products that nearly never break. We were doing it in the 70's & 80's. Then came 'planned obsolescence' - intentionally designing products to become obsolete or break quickly within a set time frame. This is that- but in reverse.

I'm gonna piss a few nerds off but this is an example of why a lightsheet microscope should be used to study organoids. The detection optics are great for imaging in XY but they suck axially. Sure, yeah, hocus pocus, RI matching, correction collar, blah blah, but it's physics, baby.

Retinal Blood Vessel Q: How small can a blood vessel get? A: Smaller than a red blood cell. bryanwjones.com/2018/08/reti... #SciArt #retina
Question: How small can the blood vessels in our retinas get?

Answer: Smaller than the diameter of a red blood cell (~6-8µm wide).

The red blood cells have to fold themselves to get through the tightest of spaces and line up, single file to get through the smallest retinal capillaries.

There are lots of data encoded in our connectomes, not just neurons.  We spend lots of time exploring and examining glia and vasculature in the retina along with the neurons.  This is one example of a small capillary in the retina that is so small, that the red blood cells have to fold themselves to get through.
