Pei-I Ku, University of Utah (image) University of Utah Caption University of Utah physics doctoral student Pei-I Ku prepares a sample for the digital microscope she uses to make movies and photographs of the AIDS-causing human immunodeficiency virus budding from human cells in the laboratory. The microscope is in a glass chamber to keep the cells at body temperature so researchers can watch the process over time. Ku is the first author of a new study in which University of Utah researchers combined imaging technology and biochemistry to make such images. The method revealed that a protein named ALIX gets involved in the process later than believed previously. Credit Tom Bear (http://tombearphotography.com) for the University of Utah.
