Understanding cell division

Cytokinesis is the final step of the process of cell division, by which the two new cells are physically separated. This process relies on a structure called the cytokinetic ring, which needs to be linked to the plasma membrane ...

New findings on the recycling centres of cells

Both animal and plant cells depend on autophagy in which damaged or superfluous cell material is removed. The degradation of substrates is done by proteins. In animals, it takes place in a cell organelle called the lysosome ...

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 ...

How bacteria protect themselves from plasma treatment

Plasmas are created from gas that is pumped with energy. Today, plasmas are already used against multi-resistant pathogens in clinical applications, for example to treat chronic wounds. "Plasmas provide a complex cocktail ...

Fidget spinner as centrifuge separates blood plasma

Some people use fidget spinners—flat, multi-lobed toys with a ball bearing at the center—to diffuse nervous energy or whirl away stress. Now, researchers have found a surprising use for the toys: separating blood plasma ...

The exocyst dynamo

The exocyst is a protein complex essential for life, that is comprised of eight subunits and is a crucial component in vesicle trafficking.
