Mysterious males: Asexual female nematodes produce males for sperm, not genes
Getting at why nematodes engaged in a unique female-favoring reproduction strategy produce males at all, researchers report that the asexual females produce limited numbers of male offspring to exploit them for their sperm in order to make more males, and in a ratio meaning the resultant sons are more likely to mate with their sisters.

#517 Life in Plastic, Not Fantastic
Our modern lives run on plastic. It's in the computers and phones we use. It's in our clothing, it wraps our food. It surrounds us every day, and when we throw it out, it's devastating for the environment. This week we air a live show we recorded at the 2019 Advancement of Science meeting in Washington, D.C., where Bethany Brookshire sat down with three plastics researchers - Christina Simkanin, Chelsea Rochman, and Jennifer Provencher - and a live audience to discuss plastics in our oceans. Where they are, where they are going, and what they carry with them. Related links:...
