    Wui Ip Professor Carl Franck and student Wui Ip (who is at Cornell as part of the NSF's Research Experiences for Undergraduates program) are studying how cells interact and signal each other to form complicated structures. For example, cells communicate when conditions are good, and they exchange growth factors. Franck and Ip are focusing on the question "Why do cells need company to grow?" It is well known that a minimum culture is needed to grow cells. What determines that ... read more
