* '30 years after the Iran hostage crisis, we're still fighting Reagan's war.'
* Ugh. Congressional hearings hidden Islamic radicalism echo McCarthy's Red Scare.
* New study of Arctic sea ice and snow show we've been underestimating the effects of climate change.
* Some phony scandals some Republicans want to spend your tax dollars investigating.
* Nice. Teacher eats 162 school lunches and lives to blog the tale.
