A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular debris.

A class of proteins known as TMEM16 scramblases permit rearrangement of lipids in the cell membrane chiefly by thinning the membrane, according to a new model by Weill Cornell Medicine investigators.

Biological processes that govern our lives are many, intertwined, and often difficult to understand. They involve countless interactions happening at once—molecules recognizing each other, signals ...

Lipid density has been shown to be the defining factor in membrane flexibility, potentially opening new avenues in synthetic biology. Research into membrane behavior has revealed that how tightly ...

Programmed cell death is an important tool that an organism uses to keep itself healthy. When a cell does not function as it should, various stress reactions are activated. The goal of these reactions ...

Lipid nanoparticles, or LNPs, are best known as the delivery system used in the COVID-19 mRNA vaccines given to billions of people worldwide. Scientists are now exploring their potential far beyond ...

Our understanding of how cells recycle lipids through autophagy -- a form of cellular degradation -- has grown significantly, thanks to a recent study. Using yeast as a model organism, the researchers ...

Researchers discovered that the mitochondrial MIM complex influences lipid droplet accumulation in yeast cells through ...

Few questions have captivated humankind more than the origin of life on Earth. How did the first living cells come to exist? How did these early protocells develop the structural membranes necessary ...
