For minority undergraduates interested in careers in science writing:
The American Association for the Advancement of Science (AAAS) is proud to offer a summer internship program for minority students interested in journalism as a career and who want to learn about science writing. Experience what it's like to cover the scientific and technological issues that shape our global community. The Internship takes place at the Washington, D.C. headquarters of AAAS's Science magazine, the largest interdisciplinary journal in the world.
The program is a paid, 10-week experience under the guidance of the weekly magazine's award-winning staff of professional science writers and editors.
More info here. The deadline is March 1. AAAS has a really good history of sponsoring media internships and fellowships, so I'd expect this to be a good gig, especially since it's paid (I'm not going to be paid for what I'm doing this summer!)
