b"Scientists Can Now Hear The Background Hum Of The Universe\\nFor the first time ever, scientists have heard the \\u201clow pitch hum\\u201d of gravitational waves rippling through the cosmos. It\\u2019s this ever-present background noise set off by the movement of massive objects\\u2014like colliding black holes\\u2014throughout the universe. Scientists have theorized that it\\u2019s been there all along, but we haven\\u2019t been able to hear until now. So what does this hum tell us about our universe?\\nSciFri producer Kathleen Davis talks with science writer Maggie Koerth about this discovery, as well as other science news of the week. They chat about the possibility of an icy planet hiding in the Milky Way, air quality problems due to wildfire smoke, an experimental weight loss drug that\\u2019s currently being tested, if our human ancestors were cannibals, and how dolphin moms use baby talk with their calves.\\n\\n\\xa0\\nCelebrating The Weird, Wonderful World Of Cephalopods\\nEvery year, Cephalopod Week reminds us of the fascinating and weird world of these sea creatures. And in this segment, recorded live at the University of Miami\\u2019s Rosenstiel School of Marine, Atmospheric, and Earth Science Auditorium, two cephalopod scientists share new research about our squishy sea-faring neighbors, how climate change is affecting squids and octopuses, and why they love working with them.\\nIra Flatow talked to Dr. Lynne Fieber PhD., professor of marine biology and ecology who has studied the nervous systems of all types marine invertebrates including cephalopod and sea slugs, and Dr. Andrea Durant Ph.D., a postdoctoral fellow in the Grosell Environmental Physiology and Toxicology Lab, who studies how tiny glass squid live in a rapidly-changing ocean.\\n\\n\\xa0\\nTo stay updated on all-things-science,\\xa0sign up for Science Friday's newsletters.\\nTranscripts for each segment will be available the week after the show airs on\\xa0sciencefriday.com."
