Midmorning Weekend: Scientific discovery
Midmorning Weekend revisits some of the best recent conversations from the daily call-in program.
Segment 1: Editing memory and consciousness
Researchers are learning more about how memories are made and lost by examining changes in the physiology of the brain. Midmorning finds out memory works at the molecular level. Andre Fenton is professor of physiology and pharmacology with the State University of New York Downstate Medical Center. Eric Kandel is a psychiatrist, neuroscientist, and professor of biochemistry and biophysics at Columbia University. In 2000 he won the Nobel Prize for Medicine.
Segment 2: From science fiction to physical reality
A renowned theoretical physicist ponders the possibility of forcefields, time travel, and other themes of science fiction. He said many of these do not violate the laws of physics, and could become reality in the next century. Michio Kaku is a theoretical physicist and author. His latest book, "Physics of the Impossible," is out in paperback. (Original Program)
Segment 3: Cosmic quandaries
A renowned astrophysicist explains the allure of Pluto, and the public outrage over its recent demotion from planet status. Neil deGrasse Tyson is director of the Hayden Planetarium and has served on NASA's advisory council. His new book is "The Pluto Files: The Rise and Fall of America's Favorite Planet."
