Eh, they're trying multiple ways of preservation to see what works best. We can't test which ones allow the best cyro-recoveries, but I don't see how it's de-facto not science.

Science means:

• Come up with a testable hypothesis

• Design an experiment to test it

• Perform the experiment

• Statistically evaluate the outcome and determine if it is evidence in favor or against the hypothesis

• Communicate the results to the scientific community

Science most definitely does not mean: "Let's try something random today and see what happens".

This is the core difference between scientific research and pre-scientific empiricism.

but stating that it's "factually false" that they do ANY research seems an overly strong claim.

The don't do any scientific research on their human corpses. They did some research on non-human animals in the past, but AFAIK, they didn't publish much.
