Ph.D. candidate Sushil Khanal, left, and Dr. Tomer Avidor-Reiss, professor of biological sciences, pull cryopreserved semen samples out of a liquid nitrogen tank that is kept at -196 degrees Celsius. The researchers found that the role of the centriole in sperm evolved from acting as a shock absorber to a transmission system, a discovery that could lead to innovative ways to help diagnose and treat male infertility.
