Twelve years after banning the execution of the "mentally retarded," the U.S. Supreme Court is examining the question of who qualifies as having mental retardation, for purposes of capital cases, and who does not.
In 2002, the high court ruled in Atkins v. Virginia that executing "mentally retarded" people is unconstitutionally cruel and unusual punishment. But the justices left it to the states to define mental retardation.
Now the court is focusing on what limits, if any, there are to those definitions.
It's been four years since the Supreme Court's controversial Citizens United ruling, the case that set the stage for unlimited and often undisclosed contribution money in federal elections. This year, the superPACs and social welfare organizations that use that money for attack ads are already at it, even as Republicans and Democrats are still choosing their candidates for the fall campaigns.
In 1895, legislators in New York state decided to improve working conditions in what at the time could be a deadly profession: baking bread.
"Bakeries are actually extremely dangerous places to work," says Eric Rauchway, a historian at the University of California, Davis. "Because flour is such a fine particulate, if it gets to hang in the air it can catch fire and the whole room can go up in a sheet of flame."
