I use this blog to gather information and thoughts about invention and innovation, the subjects I've been teaching at Stanford University Continuing Studies Program since 2005.
The current course is Principles of Invention and Innovation (Summer '17).
Our book "Scalable Innovation" is now available on Amazon http://www.amazon.com/Scalable-Innovation-Inventors-Entrepreneurs-Professionals/dp/1466590971/

Australians catch on video an octopus using tools
A video of an octopus that uses coconut shell as a vehicle, hiding cover, protective gear, and lots more.
The use of tools has become a benchmark for cognitive sophistication. Originally regarded as a defining feature of our species, tool-use behaviours have subsequently been revealed in other primates and a growing spectrum of mammals and birds . Among invertebrates, however, the acquisition of items that are deployed later has not previously been reported. We repeatedly observed soft-sediment dwelling octopuses carrying around coconut shell halves, assembling them as a shelter only when needed. Whilst being carried, the shells offer no protection and place a requirement on the carrier to use a novel and cumbersome form of locomotion — ‘stilt-walking’.
