Structure of a mitochondrial ATP synthase

ATP synthase is a universal molecular machine for energy conversion. By coupling to cellular respiration in mitochondria, it catalyzes conversion of chemical energy of cells.

Motor proteins and membrane dynamics

Membranes composed of a lipid bilayer define the outer surface of nucleated cells (the plasma membrane) and delimit the vital organelles within these cells, such as mitochondria and nuclei. The membrane curvature determines ...

Molecular energy machine as a movie star

Researchers at the Paul Scherrer Institute PSI have used the Swiss Light Source SLS to record a molecular energy machine in action and thus to reveal how energy production at cell membranes works. For this purpose they developed ...

Nano-bio-computing lipid nanotablet

Nanoparticles can be used as substrates for computation, with algorithmic and autonomous control of their unique properties. However, scalable architecture to form nanoparticle-based computing systems is lacking at present. ...

Carbon nanotubes mime biology

Cellular membranes serve as an ideal example of a system that is multifunctional, tunable, precise and efficient.
