Last week was "World DNA Day" (who knew?), and expat+HAREM pal Dr. Nassim Assefi draws our attention to 23andMe, which will analyze your personal genetic info for health and ancestry purposes.

• Always happy to see an expat writer make good! Journalist Alan Paul's memoir Big in China: My Unlikely Adventure Raising a Family, Playing the Blues and Reinventing Myself in Beijing scheduled to get the Hollywood treatment. I was pleased to be featured alongside Alan in Chantal Panozzo's Writer Abroad interview series last year...
