Scientists identify a key to body's use of free calcium

Scientists at Johns Hopkins report they have figured out a key step in how "free" calcium—the kind not contained in bones—is managed in the body, a finding that could aid in the development of new treatments for a variety ...

New insight into the maturation of miRNAs

An international research team led by Helmholtz Zentrum München, Technical University of Munich and the University of Edinburgh has used an integrated structural biological approach to elucidate the maturation of a cancer-causing ...

Faster, not stronger: How a protein regulates gene expression

Inside the cell, DNA is tightly coiled and packed with several proteins into a structure called "chromatin", which allows DNA to fit in the cell while also preventing genes from being expressed at the wrong time. Guided by ...

New force measured between proteins

Proteins organize themselves around our body cells through a self-induced force. They indent the cell membrane and thereby roll towards each other. This discovery provides new insights in processes like nutritional uptake ...

How 'inert' compounds can steal ions

Cells produce many different complexes. These complexes can occupy 40% of the cell's volume, making the cell quite a crowded environment. For that reason, a full description of complex cellular behavior is a challenge that ...
