The sci-fi future of medical robots is here, and dehydrating the stratosphere to stave off climate change

Keeping water out of the stratosphere could be a low-risk geoengineering approach, and using magnets to drive medical robots inside the body

First up this week, a new approach to slowing climate change: dehydrating the stratosphere. Staff Writer Paul Voosen joins host Sarah Crespi to discuss the risks and advantages of this geoengineering technique.

Next on the show, Science Robotics Editor Amos Matsiko gives a run-down of papers in a special series on magnetic robots in medicine. Matsiko and Crespi also discuss how close old science fiction books came to predicting modern medical robots’ abilities.

This week’s episode was produced with help from Podigy.
