How do plants defend themselves, fighting a war of attrition cell by cell? And how did a scientist in Minnesota in the 1950s reshape how we understand plant immune systems and the genetics at their heart. And of course, how does this all connect to GMOs? Let's find out.

The One with Mendel and his Peas

Modified ·

2025/10/04

Around the same time as Miescher was tinkering with DNA in Tubingen castle, a middle aged friar-scientist Gregor Mendel was experimenting with inheritance of pea plants. He was the first to define a set of mathematical rules behind inheritance that birthed the field of genetics - a field that lay dormant for a few decades before exploding in the 1900s, and continues to develop to this day. Genetics gives us the tools to reshape the living world with intention and at speed.

Genes can be a metaphor for our sense of self. But they are also real, physical, things made up of DNA parts, locked inside the cells of every living organism. In this episode we explore the materiality of genes, as well as some of the human stories behind the science.
