YOU are a source of bias, possibly the most powerful one. It's important to check news for bias, but at least as important to check yourself.

Problem: many science articles are behind paywalls. Solution: Two new tools come to the rescue by directing you to Open Access (OA) versions of articles available elsewhere:
