The MIT Biology Undergraduate (BUG) Journal is a collection of research papers, scholarly reports, reviews, and proposals published by Course 7 majors. These are in the areas of cell and molecular biology, genetics, structural biology, developmental biology, microbiology, immunology, bioengineering, physiology, and other major fields in biology.

The aim of the Journal is to teach MIT Biology majors the proper skills in communicating and describing their research to others. In general, the Journal emphasizes scholarship rather than quality of research results. Because of the preliminary nature of the work, students should not worry about negative results. In basic research, negative results help shape experiments that lead to important positive results.
