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 ...

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

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 ...

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...

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 the University of Stuttgart have succeeded in controlling the structure and function of biological membranes with the help of "DNA origami". The system they developed may facilitate the ...

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 ...
