If we can revive the head and somehow provide it with life support, we can theoretically induce morphogenesis at the base of the neck to grow the rest of the body. I'm not sure if you could do it in one pass (i.e. build a body) or if you'd need to induce morphogenesis for each individual anatomical structure (torso, shoulder, heart, left lung, right lung, etc.).
Either way, the process would be insanely creepy because you'd essentially have a baby's body growing out of an old person's head. But it should be doable.
Einstein though isn't coming back. His bioelectric networks, genome, and all other biological information states are beyond recovery. If we had done a full genome sequencing on him and performed a full bioelectric pattern scan somehow, we could potentially have reverse-engineered him. The bioelectric piece would be necessary to create Einstein as he was in adulthood, versus as he was as a freshly fertilized oocyte which is all a genomic snapshot would grant you.

So what about growing the rest of a human body for those heads in cryo?
Can we bring Einstein back yet?

There are Sea Wolves in the Upper Pacific Northwest. They are packs of wolves who swim between islands to hunt. IDK if it's true Orca's are hunting them...but they aren't very well studied anyway so I doubt there's anyone looking for evidence.

There's Sea Wolves on the BC Coast in addition to bears, so it's pretty well established that Apex predators not only can swim, but it appears is necessary in order to survive on the BC coast. I'm not knocking science here because I understand this is how the process works, but it's surprising that anyone would assume Cougars don't swim...

I imagine a cougar has webbed toes much like a Labrador does.

Better than 3D printing, we've actually been growing functioning organs in vivo in the lab for a while. Here's a paper from 2012 where organogenesis of ectopic eyes was induced in the guts of tadpoles via bioelectric pattern modulation: https://pubmed.ncbi.nlm.nih.gov/22159581/
Other experiments have also induced the growth of extra limbs, hearts, brains, etc. in developing frogs using the same bioelectric pathways.
That research developed to the point of regenerating entire limbs in adult frogs that lack regenerative capabilities, in 2022: https://www.science.org/doi/10.1126/sciadv.abj2164
Current research is underway on mice, primarily in limb regeneration.

Didn't see see a sub population of wolves in the Pacific northwest start swimming and eating fish? Could something like that be happening?

Close to Pungent Sound, in the Tacoma area.

I cant imagine they'd actually attack much while in the water, it would he an incredibly vulnerable position for them. Instinct would say that attacking a floating object (bird) would cause it to sink, and eating it would cause them to fail at swimming.

A cougar from the puget sound ate my cat, my neighbors cat, and another neighbors dog in like 2 weeks in 2009. Nearly killed my dad.
Washington cougars are just a different breed of cougar. They have zero chill and no fear. I have no problem believing they cross oceans out of spite if they really wanted to.
Fuckin’ wasps in cat form.
Edit: because apparently some people are angry: I’m being slightly hyperbolic in my word choice here. I don’t have a raging hateboner for cougars. Frankly I blame the local city more than anything for basically saying “look, we can’t do anything about it until it attacks a human”.

You gotta love it when science cannot currently explain how some repeatable experiment occurs. Always a good opportunity for a paradigm shift.
