If you're serious about science—and you want to get serious about helping to fend off the future's deadliest diseases—then becoming a biochemist or biophysicist is one of your best bets for making a difference. These super-smart scientists are hard at work in laboratories around the country as we speak, studying cells and their DNA, developing new medicines, and sharing their findings with the larger scientific community. Biochemists and biophysicists usually get their start in university programs, which pay them to contribute to important research while they get their PhDs. The best and brightest among them may go on to give speeches at conferences, manage lab teams, teach in universities, and work on important projects that span different (and seriously exciting) areas of science.
