Sleeping without a brain, tracking alien invasions, and algorithms of oppression
Manage episode 305748152 series 2943936
Simple animals like jellyfish and hydra, even roundworms, sleep. Without brains. Why do they sleep? How can we tell a jellyfish is sleeping? Staff Writer Liz Pennisi joins host Sarah Crespi to talk about what can be learned about sleep from these simple sleepers. The feature is part of a special issue on sleep this week in Science.
Next is a look at centuries of alien invasions—or rather, invasive insects moving from place to place as humans trade across continents. Sarah talks with Matthew MacLachlan, a research economist at the U.S. Department of Agriculture’s Economic Research Service, about his Science Advances paper on why insect invasions don’t always increase when trade does.
Finally, a book on racism and the search algorithms. Books host Angela Saini for our series of interviews on race and science talks with Safiya Umoja Noble, a professor in the African American Studies and Information Studies departments at the University of California, Los Angeles, about her book: Algorithms of Oppression: How Search Engines Reinforce Racism.
