For nearly a decade, scientists and Northwest tribes in Washington state fought bitterly over whether to bury or study the 9,500-year-old bones known as Kennewick Man. Scientists won the battle, and now, after years of careful examination, they're releasing some of their findings.
For starters, Kennewick Man was buff. I mean, really beefcake. So says Doug Owsley, head of physical anthropology at the Smithsonian's National Museum of Natural History, and the man who led the study of the ancient remains.

The story of the birth of accounting begins with numbers. In the 1400s, much of Europe was still using Roman numerals, and finding it really hard to easily add or subtract. (Try adding MCVI to XCIV.)

President Obama and his Republican challenger, Mitt Romney, are prepping for Wednesday's presidential debate. It's a well-worn tradition now, but it wasn't always that way.
The 1960 Kennedy-Nixon face-off wasn't just the first televised presidential debate, it was also the first presidential debate in more than a century.
Four years earlier, a young German emigre named Fred Kahn, a student at the University of Maryland, wanted to see whether the nominees — Dwight Eisenhower and Adlai Stevenson — might want to engage with students.
In the spring of 1963, as the U.S. was mired in conflicts with Vietnam and Cuba and the Soviet Union, President John F. Kennedy called his old friend David Hackett to express his frustration at the U.S. men's ice hockey team — and their miserable record overseas.
JFK: Dave, I noticed that in the paper this morning that the Swedish team beat the American hockey team 17-2. Hackett: Yeah, I saw that. JFK: Christ! Who are we sending over there? Girls?
