Podcast: An 80-million-year-old dinosaur protein, sending oxygen to the moon, and competitive forecasting

This week, we chat about how the Earth is sending oxygen to the moon, using a GPS data set to hunt for dark matter, and retrieving 80-million year old proteins from dinosaur bones, with Online News Editor David Grimm. And Philip Tetlock joins Alexa Billow to discuss improving our ability to make judgments about the future through forecasting competitions as part of a special section on prediction in this week’s issue of Science.
