First up on the podcast, bringing Gregor Mendel’s peas into the 21st century. Back in the 19th century Mendel, a friar and naturalist, tracked traits in peas such as flower color and shape over many generations. He used these observations to identify basic concepts about inheritance such as recessive and dominant traits. Staff Writer Erik Stokstad talks with host Sarah Crespi about the difficulty of identifying genes for these phenotypes all these years later. We also hear some other stories from the plant world, including evidence that wavy fields are more attractive to insects and a tree benefits from being struck by lightning.

Next on the show, a carnivorous caterpillar that haunts spiderwebs, camouflaged in its insect prey’s body parts. Producer Kevin McLean talks with Daniel Rubinoff, a professor in the department of plant and environmental protection sciences at the University of Hawaii at Manoa, about how such an adaptation might have evolved and the overlooked importance of insect conservation. 

Finally, we kick off our 2025 books series on the science of death and dying. Books host Angela Saini and books editor Valerie Thompson talk about the challenges of putting this year’s list together and the reads they are looking forward to.

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