They found that flies fed a low-protein diet had a significantly longer lifespan than those fed a high-protein diet. Further, they saw F-actin in the brains of flies on a rich diet at young middle age ...

Researchers at Kanazawa University report in eLife on deciphering the actin structure-dependent preferential cooperative binding of cofilin. The actin filament is a double-stranded helical structure ...

Humans and fruit flies both may become forgetful as they age. But because fruit flies have a lifespan of only about two months, they can be a useful model for understanding the cognitive decline that ...

J. Zenker et al., “Expanding actin rings zipper the mouse embryo for blastocyst formation,” Cell, 173:776–91.e17, 2018. Not long after egg meets sperm, the resulting mulberry-like mass of cells morphs ...

Cells grow, change shape, move, and divide. They give structure to tissues, close wounds, and hunt down bacteria in the blood. This mobility is a prerequisite for a variety of essential biological ...

Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their blueprint—the genetic information. Here, the basic building blocks of proteins, ...
