I’m assuming if the syringe was wet before being placed in the microscope, the vacuum of the chamber would cause most of the water in the plasma to vaporize. The remaining salts and compounds would be much smaller than the red blood cells. The density of the red blood cells would be much larger than any remaining plasma, so the bulk of your backscattered electrons will be coming from the cells and needle, making the plasma essentially transparent. This is a fairly low magnification image for SEM, but that’s how you get such fantastic depth of field.

No name, but for the longest time, I thought she was a man with a big mustache.

This one time at the Champaign Blues, Brews, and Barbecues festival, I opened a port-a-potty and there was a woman on top of a man inside having some fun, so I apologized and shut the door.

I really enjoyed Space Station Silicon Valley for the N64. It turns out there was a bug in the original game so you could never complete it 100%. A couple years ago, I purchased an Everdrive (https://krikzz.com/our-products/cartridges/ed64x7.html) so I could patch the ROM and play on original hardware. Pair this with some new wireless controllers and it’s the perfect experience.

I felt like I had to interrupt my wife’s reading to show her this just because I knew she would understand. I recognize I am the problem here.
