This summer…

I think it’s a question of how far they can swim.

For example, Vancouver Island (tons of cougars) has historically never had a breeding population of brown bears, which is insane given its size and abundant perfect brown bear habitat.

Turns out that it’s because female brown bears can’t quite hack the swim from the mainland. Males can, and there are always a few males wandering the island, but females don’t and as such a population never got established.

So female brown bears can swim - just not the 3 km or so that it takes to island hop from the mainland to the nearest point of Van island.

It’s this way on the coast of BC. Very dense cougar territory. If you’re kayaking through and you know there’s a cougar around, it can be a bit spooky. I’ve spent some nights on some small islands where I’ve faced the trees, rather than the beach, while sitting at the campfire. Just didn’t want to turn my back on the woods. You know they’re there.

Where did you get “and one deer”? Lolol

“Orcas have been observed preying on terrestrial mammals, such as deer swimming between islands off the northwest coast of North America.” Straight from wiki

Reply to UNSW engineers unveil prototype robotic arm that can 3D print living cells directly onto organs inside a human body. by unswsydney

Hi r/science - researchers from our Medical Robotics Lab have developed a proof of concept of a tiny flexible 3D bioprinter that can be inserted into the body just like an endoscope and directly deliver multilayered biomaterials onto the surface of internal organs and tissues.

The team behind the concept say that with further development the technology could be used by medical professionals to access hard-to-reach areas inside the body via small skin incisions or natural orifices.

Their work has been published in Advance Science if you’d like to have a read: https://onlinelibrary.wiley.com/doi/10.1002/advs.202205656
