Successful organ transplants give recipients a new lease on life – and sometimes more than that. For almost as long as heart, kidney and liver transplants have been around, people have been reporting changes in their preference for food, music, art, sex, recreation and career following surgery. And these changes often chime with the preferences of the organ donor.

Many dismiss these occurrences as being “all in the mind”. We asked anatomist Adam Taylor what he thought. It turns out there is a plausible biological basis for this strange phenomenon.

Iceland supermarket recently announced that it will be launching a “customer election manifesto”, which will be shared with UK politicians in the run-up to the election. What does this say about the state of our democracy? Plus we hear from the researcher who coined the term “microplastics” on his 20-year quest to understand how this pollution is affecting our planet, and his mixed emotions at recent attempts at a global plastic treaty.
