Neutron scattering: A window into the development of living cells

Neutrons can be used to probe living tissues without damaging them (neutron scattering). Suzan Mazur interviews biophysicist John Katsaras, whose specialty is cell membranes, at Oscillations on their implications for studying the origin and development of life forms. Among the fascinating details, Suzan Mazur: Your membranes research revealed that lipids gathered with others of their type. John Katsaras: Right. The cell makes thousands of different types of lipids. In the plasma membrane, which is the outer membrane of the cell, there are hundreds or, maybe thousands of different lipids. The question is, why does the cell expend so much energy to make all of these different lipids. You could say, well, maybe they have all different physical properties.. As a Read More ›
