Great and diverse topics, awful intro music
Very interesting! Very annoying music
Short, sharp science
I really enjoy the concise summaries of recent findings. My only criticism is that they are infrequent (fortnightly) and each episode is very short!
Nice way to get updated
Nice, short updates on some really cutting edge science. Nice interview with author. The disucssion is at a level where a lay person who does not know the branch of science being disucssed can actually understand....some of the topics are very cutting edge. Love it !!!
