Cellular structure self-organizes through an interplay between internal mechanisms and external cues. The single-celled suctorian P. collini builds a trap structure to capture large prey using microtubule feeding tentacles, creating feedback between cell morphology and prey availability.

If you believe either that Franklin discovered the double helix, and / or Watson and Crick stole her data, ask yourself how you know this. Then take a read of this article.
If I see one more stupid Rosalind Franklin take I'm going to lose my mind. Thank god for @matthewcobb.bsky.social and @nccomfort.bsky.social. www.nature.com/articles/d41...
What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.

What about the 1926 Madelung (hydrodynamic) formulation of quantum mechanics? That doesn't require imaginary numbers either.
For the first time, physicists have formulated quantum theory without imaginary numbers, overturning a 2021 claim that these unreal numbers are essential for describing the quantum world.
