There's a reason why Asian dishes often taste so different from the typical North American fare: North American recipes rely on flavors that are related, while East Asian cooks go for sharp contrasts.

That's the word from researchers at the University of Cambridge, who used a tool called network analysis to chart the relationship between chemical flavor compounds. They did it to test the widely believed notion that foods with compatible flavors are chemically similar.

Dictators suddenly seem to have a lot less longevity. This year, several of the world's longest-serving autocrats have either died or been ousted from power.

The death of North Korea's Kim Jong Il from heart failure had nothing to do with the Arab uprisings that ousted four leaders who had been in power for decades — Hosni Mubarak of Egypt, Moammar Gadhafi of Libya, Ali Abdullah Saleh of Yemen and Zine El Abidine Ben Ali of Tunisia.

It may seem counter-intuitive, but the history of world music proves that unfamiliar instruments and rhythms cross borders much more readily than vocal styles. There's no question that, starting in the late '60s, soul and then funk became very popular in sub-Saharan Africa. Decades of reissues show that a lot of players found their way into electric guitar, and that enriching the big beat of the West was a cinch for African percussionists.
