Starting as a simple tutorial excercise to demonstrate the power of Martini to study protein-lipid interactions, ending up as a full-blown paper with lots of experimental support and biological relevance ! Read all about the amazing ability of ceramides to bind to voltage dependent anion channels (VDAC) in mitochondrial membranes:

Martini simulations of the full trimeric light harvesting complex II, embedded in a thylakoid membrane, reveal interesting chromophore dynamics and lipid binding sites.
For details, check the paper which is now online: S. Thallmair, P.A. Vainikka, S.J. Marrink. Biophys. J., 116:1446-1455, 2019. doi:10.1016/j.bpj.2019.03.009
Less fuzzy lipids

A recent study by Carpenter, Lopez and coworkers nicely characterized the phase behavior of Martini DPPC/DOPC/cholesterol ternary mixtures. General Martini parameters correctly captured a large fraction of the phase diagram, but parameters optimized against CHARMM DOPC and DPPC simulations could better capture some of the details, especially close to the critical point.
The new lipid parameters specifically tuned to CHARMM DOPC and DPPC can be found here and in the Martini lipid parameter list: DPPC and DOPC.
