Greg Louganis is the best diver of his generation — perhaps the best the world has ever seen. The four-time gold medalist is the only man to ever sweep the diving events in consecutive Olympics.

The new documentary Back on Board, by director Cheryl Furjanic and producer Will Sweeney, contrasts that success with the inner turmoil Louganis experienced rising to stardom at such a young age.

According to a review of the results of 12,000 blood tests, the world of track and field has a doping problem that is as big as the one cycling had at the height of Lance Armstrong's popularity.

That's according to the Sunday Times and Germany's public broadcaster ARD/WDR, which obtained a leak of documents with the bloodwork of 5,000 athletes.

Thomas Jefferson's vision of democracy has endured in one of the defining documents of U.S. history. But the 607 slaves who toiled in his Monticello estate have left few traces to remember them by.

After a bunch of really nice humans helped a hitchhiking robot traverse the length of Canada and most of Germany, the robot was going to try to make it from Massachusetts all the way to California.

According to Article 19, a group that advocates for press freedom, Rubén Espinosa is the 88th journalist killed in Mexico.

While the Catholic Hill experience is unique in many respects, it is emblematic of the struggle for the faith in the way that the people of Catholic Hill maintained their identity despite decades of hardship and neglect. Professor Allison McCletchie, of Claflin University, is leading a small team that is creating an ethnography of Catholic Hill.
