The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Shutting down microglia

Developing brain tumors can coax assistance from nearby cells known as microglia, according to a new study from scientists at Washington University School of Medicine in St. Louis. The researchers have identified one protein made by microglia that helps accelerate tumor growth and are looking for others.

Cell structures exhibit novel behaviors, mimic red blood cells and liquid crystals

Researchers at the University of Pennsylvania and Yale University have manipulated the internal, structural components of cells, creating a set of simulated cellular structures with novel mechanical properties, including one that acts like a red blood cell and another that mimics the soft, elastic behavior commonly found in novel synthetic materials called liquid crystal elastomers.
