The image above shows a bipolar mitotic spindle (dark blue) inside a dividing cell. Mitotic spindles can rebuild and dissolve structures within a cell millions of times per day, a process of self healing scientists cannot currently replicate with modern materials. UMass Amherst cell biologist Patricia Wadsworth and biophysicist Jennifer Ross are researching this process at a deeper level to understand the principles that allow this molecular machine to function. Wadsworth and Ross aim to incorporate physical and material engineering with biology to approach the problem. Learn More.
