Evolutionary model predicts partitioning of molecules within cells

Researchers from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) in Göttingen, Germany, and Delft University of Technology, the Netherlands, have developed a new theoretical method to study mixtures consisting of many different molecules. They analyzed how the molecules interact to reliably form different droplets, as happens continuously in living cells. With this model, particular droplet formation based on many interacting molecules can be predicted for the first time. The findings were recently published in the scientific journal PNAS. more

First electric nanomotor made from DNA material

A research team led by the Technical University of Munich (TUM) has succeeded for the first time in producing a molecular electric motor using the DNA origami method. The tiny machine made of genetic material self-assembles and converts electrical energy into kinetic energy. The new nanomotors can be switched on and off, and the researchers can control the rotation speed and rotational direction. more

Competing cells: Cleaning up after yourself brings benefits

When different cell types compete in a confined space, those which remove debris faster have a better chance to dominate their environment. Researchers from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) showed in their model that not only a higher net proliferation rate, but also the swift removal of dead cells provides a competitive advantage. They mixed two cell populations only differing in debris removal rate and showed that already after a few generations the population with the higher removal rate starts to dominate the confined space. more

How blood vessels remember a stroke

Networks adapt over time and in this way form a kind of memory. This is the key finding of a new study by researchers from the Max Planck Institute for Dynamics and Self-Organization in Göttingen and the Technical University of Munich. They show that the structure of blood vascular network is dynamic and can adapt to external factors. In particular, the scientists found that rarely used connections are weakening more and more until they disappear eventually. more

Young researchers from Göttingen receive Otto Hahn Medals and Otto Hahn Award

Mirna Elizabeta Kramar from the MPI for Dynamics and Self-Organization and Jascha Lau & Michael Weber from the Max Planck Institute for Multidisciplinary Sciences receive the Otto Hahn Medal for outstanding achievements in their dissertations. Lau is additionally honored with the Otto Hahn Award for the special quality of his research. The Max Planck Society presented the awards at its annual meeting on June 22.

A link between entropy production and topology

The Department Living Matter Physics from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) revealed a link between the generation of entropy and the topological features of a system. In their study, recently published in Nature Communications, the scientists investigated the random motion of particles in vortex flows. They found that fluctuations in entropy production can be characterized based only on the number of windings around the vortex, but not on the shape or size of the trajectory. These findings could contribute to a better understanding of microscopic systems, such as micro-motors or particles moving in biological media. more

It's all in the mixing

It's all in the mixing

May 12, 2022

A group of scientists led by Nate Cira of Harvard and Cornell University and Stefan Karpitschka of the Max Planck Institute for Dynamics and Self-Organization has discovered that some liquid droplets first spread out on surfaces and then contract again on their own. This boomerang effect depends on the composition of the droplets. Since these leave virtually no traces when they contract, unlike conventional drying, this opens up new possibilities for cleaning and removing particles from sensitive surfaces such as microchips. more

Wool balls in the wind: The geometry of turbulent mixing

Anyone who regularly stirs their coffee knows about the advantages of turbulent mixing: the movement of the spoon creates a turbulent flow that can distribute the milk very quickly and evenly in the cup. Moreover, turbulent mixing is also responsible for the distribution of gasoline in the engine cylinder or of dust particles in the atmosphere. The research group led by Prof. Michael Wilczek at the Max Planck Institute for Dynamics and Self-Organization and the University of Bayreuth has now succeeded in better understanding the geometry of turbulent mixing; their results were recently published in Nature Communications. more
