Marilyn,
Im sure your question was directed for efex, and Im sure she'll give ya more info but at my school, some of the biology professors have research projects that you can participate in during the semesters, and/or over the summer. Once your particular project is completed, usually you and your research partner (the professor) go to a seminar proposing your research to other researches and biologists, and you may or may not get published. I only know this little because my cell bio professor does research on crustacean endocrinology and metabolic pathways and a student did some research with him, and they went to a seminar. They didnt get published though, that looks good for med school but I think some unpublished research would be better than none!
Im still waiting Mayo's response, Ill post it as soon as I get a reply!
