Flashback to the 1980s, when President Ronald Reagan tried to restrict funding for Planned Parenthood. Efforts in Congress have continued since then, with the latest focused on fetal tissue research.
On Monday, President Obama will unveil tougher rules designed to cut carbon emissions from U.S. power plants. If the proposed plan clear legal hurdles, the nation's power grid would face big changes.

They call it "oleogustus," or the taste for fat. But nutrition scientist Rick Mattes says it's far from delicious. Found in rancid food, it's often an unpleasant warning.
There's a new, sixth taste for humans: the taste for fat. But Rick Mattes of Purdue University tells NPR's Rachel Martin to think less yummy ice cream, more rancid food.
