2-dimensional phase separation in cell membranes: How yeast harness physics to organize proteins and lipids

Event Information:
(No prior knowledge of biology is required for this talk!) For decades, scientists have argued about how living cell membranes acquire and maintain regions enriched in particular lipid and protein types. One of the more contentious theories has been that lipids and proteins spontaneously phase separate within the plane of the membrane to create liquid regions that differ in their composition. Physicists have long observed this type of demixing in simple artificial membranes. Clear identification of the same transition in a living biological system has heretofore been elusive.
