<p>A few programs that I know of --
NIH</a> internships in biomedical research
NSF</a> Research Experiences for Undergraduates
MIT</a> Summer Research Program</p>
<p>I don't know, however, that I'd go so far as to say that these pay "good money". Haha, if you're planning to be a Nobel-prize-winning scientist, I'd highly advise you to get used to making not so much money!</p>
