Molecular engines are based on different principles than macroscopic motors. I will present two examples: artifical engine created in our lab namely nano-wind mill driven by evaporation of water and the motion of kinesin motor walking on microtubules. This biological engine, of incredibly efficiency, is driven by thermal noise, while consumption of ATP is mainly used for detachment of its...

The DNA in a human cell is ~3 meters long. It is dynamic and yet is well organized. What are the mechanisms that organizes the chromatin and chromosomes in the nucleus?
Using dynamic methods in live cells, we identified a mechanism that maintains the genome organization in the nucleus. We claim that lamin A forms chromatin loops by lamin A dimers (or oligomers) thereby restricting the...

In living cells, proteins often bind to specific basepair sequences on DNA, such as transcription factor proteins that regulate gene expression, or restriction enzymes that cut the DNA at cleavage sites. These proteins search for targets that are about 10 basepairs long, on a DNA that is a few mega basepairs in bacteria, and billions in humans. This sounds like a needle in a haystack- problem...

Extended numerical simulations of threshold models have been performed on a human brain network with
N=836733 connected nodes available from the Open Connectome Project [1]. While in the case of simple
spreading models like contact process, SIS or threshold model a sharp discontinuous phase transition, without any critical dynamics arises, variable threshold models exhibit extended...
