Early indications have 2012 as a poor week for science and technology guests late at night. I suspect much of this has to do with it being an election cycle, which affects The Colbert Report and The Daily Show more than other late night programs. Of course, these shows are also the top sources of late night science and technology content in the U.S. (and in repeats this week).
The only broadcast contender of note in this category does manage to come through this week. Dan Riskin, now a frequent guest on The Late Late Show with Craig Ferguson, will visit on Friday. Besides hosting various science programs aimed at one’s squeamish centers (insects and infections feature prominently), Riskin can be seen on the Daily Planet show on Discovery in Canada. I hope Discovery in the U.S. picks him up, but they probably haven’t finished tracking down all the special Alaska jobs that don’t have programs.
