When do lipids (de-)mix?

Whether or not a mixture of multiple lipids forms a homogeneous bilayer is an important, and surprisingly difficult, problem in membrane biophysics. Shushan’s recent paper describes a new method that allows the accurate calculation of mixing phase-diagrams from coarse-grained simulations.

Kayla’s work on membrane-mediated protein interactions

When proteins bind to cell membranes they affect local membrane properties. In particular, the membrane can no longer fluctuate the way a free membrane would: the proteins suppress membrane fluctuations, which is entropically unfavorable. This results in a membrane-mediated interaction among membrane-bound proteins. You can read more about this effect in Kayla’s recent paper, which Read more about Kayla’s work on membrane-mediated protein interactions[…]
