Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

The functions of biomolecules, including lipids, nucleic acids and especially proteins are determined to a great extent by their structure. This structure–function relationship is a foundation of many ...

A study could open new pathways for understanding how cholesterol influences cell membranes and their receptors, paving the way for future research on diseases linked to membrane organization. A new ...

A novel technology that utilizes light of different wavelengths to control cellular functions by inducing reversible assembly and disassembly of molecules has been developed. This breakthrough could ...

The so-called NKCC1 protein is found throughout the human body where it has important functions in organs that process fluids or perform neurotransmission. A research team has now determined a ...

The havoc that viruses wreak in personal health and civic life is completely out of proportion to their size. How can something so small — a microscopic bundle of protein and nucleic acids — be so ...

Delivering a connection-building protein to star-shaped cells in the brain could reverse changes to neural circuits seen in ...

More than a billion years ago a hungry cell devoured a tiny blue-green alga. But instead of the former simply digesting the latter, the duo struck a remarkable evolutionary deal. Now scientists are ...

Around the globe, heart disease remains one of the top causes of death. Once patients begin to suffer from serious heart ...
