First simulation of a full-sized mitochondrial membrane

Scientists from the University of Groningen have developed a method that combines different resolution levels in a computer simulation of biological membranes. Their algorithm backmaps a large-scale model that includes features ...

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 ...

The mechanism of cellular migration mode switching

When faced with difficult terrain, off-road vehicles can switch from two- to four-wheel drive to keep moving forward. Similarly, cell migration can be driven either by protrusion-directed crawling, or by contractile pulling ...

Researchers discover a trigger for directed cell motion

When an individual cell is placed on a level surface, it does not keep still, but starts moving. This phenomenon was observed by the British cell biologist Michael Abercrombie as long ago as 1967. Since then, researchers ...

Pulses for better posture

In an effort to find a better treatment for spinal curvature in children and young people, the EU's "StimulAIS" project is focused on electrostimulation of muscles. Fraunhofer scientists worked with partners from industry ...
