“Brian”, a graduate student in geology, at his blog …Or Something…, reviews science podcasts. Under the microscope are Nature‘s weekly podcast, Science Friday, Science Times, Science Talk and PopSci’s podcast. Here’s what Brian writes about the Nature podcast:

This is one of the longer ones at about 25-30 minutes and is published once a week. This podcast sums up 3 or 4 of the prominent articles that are reported in the weekly journal Nature. The format is typically a phone interview with one or more of the authors of a study in that week’s issue. This is the most technical of all the podcasts listed here.
