I feel like the description goes too far in physical detail, it kind of bogs down the stronger parts of the article. It could probably shortened to 3 or less paragraphs. Also, I think it doesn't really need to have flight. The pyrokinetic power makes some sense as an expression of power generation, but I don't see the thematic connection with telekinesis/flight other than it's ability to hold itself together.
I quite like the log and the communist uprising of the mitochondria. It's a surreal and fun idea, kinda reminds me of that sentient flu that acts as a military (crosslink potential there?)
Last thing is some tonal/stylistic issues, I don't think the Foundation would use the term ESP in this context, and "even the best of the Linguistic Department" sounds pretty informal. I think that footnote could rewritten, but I'm not sure how to word it.
