I m confident you will have better ones. Ideally you should have some deep curiosity about the topic you pick. Shorter papers are usually better . Use figures as necessary. Use section headings liberally, and keep paragraphs short.
Scientific writing is dense, and needs leavening.
Use any reference style you like, but please include full titles to all referenced articles. You are encouraged to use PubMed and an automatic reference database and bibliography maker such as EndNote . I will offer a brief tutorial on Medline and EndNote if there is interest. You may begin your literature search with a review article, but you should then go to the original literature. Don't try to be comprehensive with regard to the literature, but instead try to select excellent papers and study them thoroughly.
