#33: The healthy-eating revolution; China’s cosmic ambitions; Russia’s pursuit of gene-editing technology; the world’s greatest mammal

If you’ve longed for the day when scientists announce pizza is actually good for you, you *may* be in luck. It turns out there’s no such thing as a universally wholesome diet  - what’s healthy for one person might be harmful for the next.

In the pod this week are New Scientist journalists Rowan Hooper, Valerie Jamieson and Graham Lawton.

The team discusses the advent of a healthy eating revolution. “Precision nutrition” aims to measure the metabolic response of individuals to certain types of food, to figure out what foods are good and bad for people on a personal level. Maybe, for you, chocolate cake really is the best breakfast?

Elsewhere on the show we hear the squeaky sounds of the naked mole rat, as we learn that not only are these legendary mammals practically blind, but they’re also almost completely deaf. The team hears about Vladimir Putin’s thoughts on the potential for gene editing in humans, discusses China’s recent launch of a reusable space plane, and checks in on the “Great Green Wall” project to plant a belt of trees across the whole width of Africa.
