End to life worthy of being envied.
I love that Magawa's wikipedia article is structured just like a human: Early Life, Career, Retirement and Death.
A few weeks ago when "Croatia declared free of landmines after 31 years" was posted here (https://news.ycombinator.com/item?id=47189535), I rabbit holed wikipedia about landmine-sniffing animals. It's such a fascinating topic.
Just missing the "controversies" and "personal life" sections!

How does one rat mentor another?
You can teach a kid to change a tire without saying a word. It’s the same thing. Rats are very smart and very social. Rats that were good at teaching Rathood to their little ones had more that survived.
Put food in a maze and I’m sure rats would teach other rats how to get it. I expect this is similar.
My guess, first they send them links to confluence wiki.
All deprecated pages with outdated info of course. But the comments have links to Slack threads about the incorrect info.

Rats are intelligent social mammals. They teach by actions. Imagine training a dog. You have two dogs, one trained and one not. You say "sit" and the trained dog sits and you give it a treat. The non-trained dog will quickly pick up on that.
