Researchers, regulators, and the chicken industry are all united in their search for a way to make eggs more ethical by stopping culling—the killing of male chicks born to laying hens. Contributing Correspondent Gretchen Vogel talks with host Sarah Crespi about the many approaches being tried to [determine the sex of chicken embryos before they hatch-linkTK], from robots with lasers, to MRIs, to AI, to gene editing with CRISPR.

 

Also this week, Sarah talks with Melanie Bergmann, a marine biologist at the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, Germany, about finding microplastic particles in snow all the way up at the Fram Strait, between Greenland and the Svalbarg archipelago in Norway.
