New graduate students or advisors take note: Bitesize Bio's Suzanne Kennedy gives 10 tips to help you or your student survive those graduate-student years. First, Kennedy suggests finding a mentor who can help you when your advisor is playing hard to get. She also advises making friends with everyone — "don't burn any bridges" — and collaborating with other labs. On the more technical side, Kennedy recommends cleaning the incubators regularly and having your own stock of reagents to keep contamination low.
