A simple, chemical materials model may lead to a better understanding of the structure and organization of the cell according to a Penn State researcher. "Cells are interesting because they show ...

A eukaryotic cell (left) has membrane-enclosed DNA, which forms a structure called the nucleus (located at center of the eukaryotic cell; note the purple DNA enclosed in the pink nucleus). A typical ...

This article was originally featured on Knowable Magazine. More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the ...

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 ...

Researchers have optimized a special X-ray process -- known as soft X-ray tomography -- to deliver high-resolution three-dimensional images of entire cells and their molecular structure in just a few ...

Identifying and delineating cell structures in microscopy images is crucial for understanding the complex processes of life. This task is called "segmentation" and it enables a range of applications, ...

Scientists at Feinberg are reshaping scientific understanding of the cell's tiniest components—structures once thought to be static, now revealed to be dynamic engines of cellular life. As they probe ...
