Not long ago, Cory told you about how the Canadian government has been muzzling scientists—refusing to let them speak freely with the press and, thus, controlling what research the public gets to know about. Not surprisingly, it's research on topics that are politically inconvenient to Prime Minister Stephen Harper's government—climate change, for instance—that end up getting frozen.

This issue was the topic of a panel at the American Association for the Advancement of Science conference in Vancouver.
