This week, The Scientist ranks readers' picks for the top 40 places to work in industry in 2011. Notably, the top three firms overall are each staffed by no more than 100 employees. This year, Epizyme — the Cambridge, Mass.-based drug-development company, which has fewer than 50 employees — takes top honors. The Scientist notes the firm's "integrity" and "communications" as its greatest strengths.
