Cell 'bones' mystery solved with supercomputers

Our cells are filled with 'bones,' in a sense. Thin, flexible protein strands called actin filaments help support and move around the bulk of the cells of eukaryotes, which includes all plants and animals. Always on the go, ...

Frozen: Cutting-edge technology reveals structures within cells

Temperatures of -196 degrees Celsius enable high-resolution imaging of the cell's interior. Researchers at the Institute of Science and Technology (IST) Austria are thus able to show for the first time how the active form ...

Urge to merge: Understanding how cells fuse

Scientists have known for a decade that cells that fuse with others to perform their essential functions—such as muscle cells that join together to make fibers—form long projections that invade the territory of their ...

Actin 'avalanches' may make memories stick

If you're on skis, you want to avoid avalanches. But when the right kind happen in your brain, you shouldn't worry. You won't feel them. They're probably to your benefit.

Simulations show fundamental interactions inside the cell

Actin filaments have several important functions inside cells. For one, they support the cell membrane by binding to it. However, scientists did not know exactly how the actin interacts with the membrane lipids. Simulations ...

Lane change in the cytoskeleton

Many amphibians and fish are able to change their color in order to better adapt to their environment. Munich-based scientists have now investigated the molecular mechanisms in the cytoskeleton necessary for this and revealed ...
