The standard rat cage used in the U.S. (right) has 140 square inches of floor space. One interpretation of the new guidelines says this cage wouldn't be big enough to hold a male rat, a female rat and their babies. Instead, labs would have to house the rat family in a larger cage, like the 210-square-inch one on the left.
Scientists do experiments with millions of rats and mice each year, to study everything from heart disease to cancer to diabetes. Recently, some new recommendations about how to house female lab rodents and their babies caused an uproar, with experts at major research institutions now saying they're unsure of what they'll have to do to keep their government funding.

It's no secret who the most popular Republican is in this year's GOP presidential race. In just one single debate last year, GOP candidates mentioned the former President Ronald Reagan 24 times.
Right now, each candidate is vying for the mantle of Reagan conservatism. Yet some historians, and even some of the folks who worked for Ronald Reagan, are now wondering whether Reagan himself was enough of a Reagan conservative — at least the way it is defined today.
So what exactly is a Reagan conservative anyway? If he were alive, could Reagan get the GOP nod?
