yes, starting research freshman year is great, but i would not do it through ls10h or through the biomedical research minor. the most successful student researchers i have known have all found their labs through cold-contacting professors and expressing sincere interest.
just find a lab this spring, work your butt off through sophomore and junior year, and perhaps you will get your name on a publication before you apply. that is the goal of all student researchers, essentially.
again, the largest hurdle is finding a lab that encourages growth and a PI who allows students to take on large responsibilities. all ls10h is useful for is teaching some random techniques to you that could be taught in a few hours in a 1 on 1 situation in a lab.
finding a lab that will allow you to publish in the future is a gamble, unfortunately. you can never tell a PI that you want to be in the lab solely for a publication...you have to figure it out through other students who work in the lab.
even if you don't publish, it's ok. commitment to a lab is the most important thing. i know someone who did not publish anything but was accepted to top tier md/phd programs.
