Product Description An engaging introduction to stem cells for young scientists How do you heal when you cut your skin or break a bone? How does your body keep making new blood or brain cells, or even second teeth? How does a plant keep growing larger? The answers lie in stem cells, which are found in every growing plant and animal. Keeping the subject simple enough for young readers, a pioneer of stem cell research explains cells, tissues, normal growth, what can go wrong, and how to fix it.
Circular We're told if the economy is growing, and if we keep producing, that's a good thing. But at what cost?

Guests include economist Kate Raworth, environmental activist Tristram Stuart, landscape architect Kate Orff, entrepreneur David Katz, and graphic designer Jessi Arrington.
#504 The Art of Logic How can mathematics help us have better arguments? This week we spend the hour with "The Art of Logic in an Illogical World" author, mathematician Eugenia Cheng, as she makes her case that the logic of mathematics can combine with emotional resonance to allow us to have better debates and arguments. Along the way we learn a lot about rigorous logic using arguments you're probably having every day, while also learning a lot about our own underlying beliefs and assumptions.
