The content is great and I enjoy keeping up with developments in science with help of this podcast. However, some of the interviews are recorded over poor quality phone lines, which makes it hard to comprehend. In combination with often hard to understand accents of interviewees, certain segments of podcasts are unlistenable. Enhancement in quality of audio would solve the problem.
In addition, this podcasts features one of theist annoying hosts. Several times during every interview story is interrupted by comments like "huh", "hm", "wow!", "ha", "aha" etc. after listening to several podcasts, this unnecessary and unprofessional exclamations start to annoy and ultimately deteriorate further the quality of podcast.
