Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

In A Nutshell As cells age, they deliberately shrink a major internal structure called the endoplasmic reticulum. This downsizing happens early in adulthood and shifts cells away from protein ...

The beta cells of the pancreas are responsible for releasing the hormone insulin, which is vital for the absorption of glucose from the bloodstream. Various factors can impair the ability of these ...

Scientists have crossed a startling new frontier in bioengineering: they can now fabricate intricate three-dimensional objects inside living cells. Instead of sculpting tissue from the outside, they ...

In a recent study published in the Proceedings of the National Academy of Sciences (PNAS), researchers at the Texas A&M University Health Science Center (Texas A&M Health) identify a novel RNA ...

How the Cell's Internal Framework Shapes Brain Development Actin plays a central role in the cytoskeleton, the internal framework that gives cells structure and helps move materials inside them. In ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

For the first time, high-resolution time-lapse videos of tiny bits of living plants show how they assemble their protective cell walls, researchers report March 21 in Science Advances. The image ...
