After their dad served 4-year-old fish for dinner one night, listener Max wants to know how long you can safely keep food in the freezer. Food safety expert Haley Oliver serves up the juicy details. Plus, can tiny eyes see things we can’t? Spider expert Sebastian Echeverri takes us behind some of the most impressive peepers in the animal kingdom. Thanks to listener Miles. In the original version of this episode, we made an error about the types of light jumping spiders can see. All jumping spiders that have been studied are able to see UV and green light. Some species, including the Oregon paradise jumping spider, can see red as well. We apologize for the error and have corrected it in this version of the show.
