On January 15, Science Cafe Woo and the EcoTarium in Worcester will present You’re the Expert at the EcoTarium.  Those 18 and older are invited to join the audience for this live show and podcast taping, featured on Boston’s NPR news station, 90.9 WBUR.  Through games, sketches, and misguided guesses, a panel of comedians will try to get to the bottom of what a distinguished scientist (Nobel Prize Laureate, Craig Mello) does all day.  Purchase tickets ($20) online or call 508-929-2703 before 4PM on January 14.  Doors open at 6:30PM.
