The flagellum is an intricate biological machine that enables bacteria to move through liquids. This image created by Mariana Ruiz Villarreal shows the dozen-or-so parts of the flagellum. As sodium or hydrogen flow across the bacterial membrane, their movement drives the spinning of a rotor, which in turn drives the shaft inside the flagellum's whip-like tail. Some bacteria have flagella that rotate as much as 1,000 times per second, or 60,000 rotations per minute.

Nuclear physics at Indiana University Bloomington has come a long way. The program was created 70 years ago by A.C.G. Mitchell, hired by former IU President Herman B Wells to initiate basic physics research in 1938. Between 1939 and 1941, faculty members and students worked in Swain Hall to build the program's centerpiece, a 90-ton "cyclotron." The Swain Hall cyclotron is gone, but IU cyclotron research is alive and well.
