SK8292 Brain protein in Parkinson's research, fluorescent light micrograph. Fluorescent dyes have been used in these glial cells (brain support cells) to highlight cellular structures and proteins: actin (green), cell nuclei (blue), tau protein (red and pink). Actin is a protein that is a major part of a cell's cytoskeleton. Tau protein is an abundant neural protein, but aggregations of this protein are thought to play a role in brain disorders such as Alzheimer's disease. Tau's possible role in Parkinson's disease is being investigated here. Credit: Roger J. Bick & Brian J. Poindexter / UT-Houston Medical School / Science Source

BV4911 Noroviruses in the gastrointestinal tract. Noroviruses are a group of related, single-stranded RNA, non-enveloped viruses that cause acute gastroenteritis in humans. Noroviruses were previously known as Norwalk-like viruses(NLV). Noroviruses spread from person to person through contaminated food or water, and by touching contaminated surfaces. It is recognized as the leading cause of nonbacterial foodborne-disease outbreaks in the United States. Also shown are cross-sections of villa and epithelial cells.
