132 | Michael Levin on Growth, Form, Information, and the Self

132 | Michael Levin on Growth, Form, Information, and the Self

As a semi-outsider, it's fun for me to watch as a new era dawns in biology: one that adds ideas from physics, big data, computer science, and information theory to the usual biological toolkit. One of the big areas of study in this burgeoning field is the relationship between the basic bioinformatic building blocks (genes and proteins) to the macroscopic organism that eventually results. That relationship is not a simple one, as we're discovering. Standard metaphors notwithstanding, an organism is not a machine based on genetic blueprints. I talk with biologist and information scientist Michael Levin about how information and physical constraints come together to make organisms and selves.

Randomness and probability are central to modern physics. In statistical mechanics this is because we don't know everything about the distribution of atoms and molecules in a fluid, so we consider a p...

191 | Jane McGonigal on How to Imagine the Future

The future grows out of the present, but it manages to consistently surprise us. How can we get better at anticipating and preparing for what the future can be like? Jane McGonigal started out as a ga...

Biological organisms are pretty good at healing themselves, but their abilities fall short in crucial ways. Planaria can be cut into pieces, and each piece will regrow into an entire organism; but for...

All societies grant more power to some citizens, and there is always a temptation to use that power for the benefit of themselves rather than for the greater good. Power corrupts, we are told — but to...
