Domesticating bears, raccoons, pandas

Wolves were domesticated long ago as dogs. Wolves, bears, raccoons and pandas are closely related evolutionarily. It therefore seems like an interesting experiment to try moving the dog domestication genes into related animals. A friendly panda would be very popular to be sure. Best of all, the foregoing are different sizes, so, specialized friendly brutes can be created for both useful purposes and for fun.

If anyone is wondering why I haven't been posting lately, it is because I'm working on some heavy duty physics stuff that is taking full time.

Living bridge made of tree roots

In Cherripunji, India the natives make bridges across streams with the roots of a variety of the ficus tree.

They simply string the roots across the ravine, allow them to grow and become stronger, then in about 15 years, they are strong enough to support people as traffic.
