The major cytoskeleton protein actin undergoes cyclic transitions between the monomeric G-form and the filamentous F-form, which drive organelle transport and cell motility. This mechanical work is ...

Some cells, such as immune cells, are highly mobile—they constantly remodel their shape, migrate toward a wound that needs to ...

Science, founded by Thomas A. Edison in 1880 and published by AAAS, today ranks as the world's largest circulation general science journal. Published 51 times a year, Science is renowned for its ...

Using electron microscopy and high-speed atomic force microscopy, researchers show the internal molecular motor behind the gliding mechanism for Mycoplasma mobile to consist of two ATP synthase-like ...

High-Density Lipoproteins (HDL), also known as “good cholesterol”, remove excess cholesterol from the body’s tissues and transport it to the liver. This process is known to prevent atherosclerosis, ...

Osaka, Japan – The intestinal microbial ecosystem includes diverse species of bacteria. These bacteria can produce bioactive metabolites that directly affect the host’s immune system. An imbalance of ...

Inside nearly every cell of your body, the tiny F1 motor works non-stop to create adenosine triphosphate (ATP), the universal ...

Certain biological molecules are able to move in a “quasi-mechanical” way, and these can be considered to be molecular machines. These are seen in many natural processes, and from this, ...
