Researchers found a "garbage man" enzyme that tags toxic clumps of proteins in the brain for removal, and saw a correlation ...

The structural and functional characteristics of mitochondria shape their role as signaling organelles, with far-reaching ...

For the first time, researchers have directly visualized how newly formed cellular organelles leave the endoplasmic reticulum (ER) and transition onto microtubule tracks inside living cells. This new ...

Every second, millions of cells in your body divide in two. In the space of an hour, they duplicate their DNA and grow a web of protein fibers around it called a spindle.

The navigation of stem cells and progenitors to sites of tissue growth, the long-range extension of neuronal projections, and the large-scale movement of cells up or down external gradients all ...

The discovery that tissues use electricity to expel unhealthy cells is part of a surge of renewed interest in the currents flowing through our bodies. We’re used to thinking of the brain as an ...

While our cells are performing some important, basic functions, they can generate compounds known as reactive oxygen species (ROS). These include stuff like superoxide and hydrogen peroxide (H 2 O 2).

Think back to that basic biology class you took in high school. You probably learned about organelles, those little “organs” inside cells that form compartments with individual functions. For example, ...

Decades of textbook biology may need to be rewritten after an imaging study has revealed that hair does not grow by being pushed out from the root, as previously believed—but is pulled upward by ...

Stem cells in most organisms typically take cues from adjacent cells. But new research from the Stowers Institute for Medical Research has found that stem cells in the freshwater planarian Schmidtea ...
