The moon jellyfish has remarkable
approach to self-repair. If it loses a limb, it rearranges its remaining
body parts to once again become radially symmetric. Humans can’t do that,
but a new approach that combines biology with nanotechnology could give our
immune systems a boost. Would you drink a beaker of nanobots if they
could help you fight cancer?
Also, materials science gets into
self-healing with a novel concrete that fixes its own cracks.
Plus, why even the most adaptive
systems can be stretched to their limit. New research suggests that the
oceans will take a millennium to recover from climate change.
