Anyone want to guess what this is?

Hints: it's natural, not human made. It's a false color image, with each color representing a different element. There are five colors. Blue is calcium.

It would help to know what the other elements might be..... is that suppose to be part of the mystery too?

Everyone is on the right track.

The other elements are iron and silicon (both shades of red), sulphur and uranium (different shades of green). I used additive (RGB) mixing.

Here's a higher resolution picture of the same thing, in B&W, where the shade is determined by density (more dense=white):

What kind of machine makes that image? Or will that give it away...

It's a scanning electron microscope in backscatter mode (BSE).

I've seen electron micrographs of prions that looked like that...

1) You can't get married to your spouse who is the same sex as you.
2) You can't have an abortion no matter how much you don't want a child.
3) You can't have a certain plant in your possession or you'll get locked up with a rapist and a murderer.

4) We need a smaller, less-intrusive government.

Not a prion. The round structures that are white in the first picture are natural but non-biological.

Getting colder now.

Suess has been the closest so far. Nerves, among other things, are involved, but there are no nerves in the picture.

It's a plaque within a brain.  Essentially a dead neuron.

Yeah, I was gonna say they were vesicles filled with some type of neurotransmitter,  but the OP said the spots were non-biological.

they also look like some type of protein within a cell that was immunolabeled.

The images show only the elements calcium, iron, sulphur, silicon, and uranium. Organic material, if present, would not be visible. No nerves or cells are visible.

Two more hints: 1. The object is of biological origin, but has been heavily modified by three non-biological processes. 2. The blue colored area is composed primarily of calcium phosphate of biological origin.

That's ten questions down, ten more to go.

Hmmm, okay I'm going back to my original guess of some kind of micro fossil. Like a fossilised algae cell.
