Lipidic membrane (surface) with with a conical trans-membrane protein (cone) moving through it. At the contact point with the membrane, the protein has a 10 nm diameter.  The movement of the membrane elements with respect to the protein are given by the arrows—the arrow length is the distance travelled in ~ 5 s. The protein deforms the membrane, both through its conical shape and through its movement. 

Simulation of the a chemical-reaction network with three species 'L', 'R' and 'A' with the Gillespie method, which has been improved by leveraging the bitwise representation of numbers in a computer. Here, 64 copies of the system, stored in 64-bit words, are initialized with an independent, random initial condition. These copies are simulated in parallel; each copy corresponds to a column in the plots for N_L, N_R and N_A. The same random number (drawn in the unit interval, top left) and time (shown as a function of the simulation steps, bottom left) are used to simulate the dynamics of all copies.
