       | civilization considers cows sacred for centuries; new rulers
       | decide cattle branding and breeding control are just commerce" ..

           | How is this different from other nitrogen-fixing species that
           | are already known? Some olives, plenty of legumes such as soy
           | beans, clover and alfalfa all have symbiotic relationships
           | with bacteria for this.

             | It does it in a radically different way - pulling bacteria
             | up from the soil into weird drippy goo from roots dangling
             | midair. The video and various articles aren't totally clear
             | on this point, but it suggests it can pull _a lot_ more
             | nitrogen out of the air than other known nitrogen fixing
             | plants (which keep the bacteria underground on their
             | roots).
