The functions of biomolecules, including lipids, nucleic acids and especially proteins are determined to a great extent by their structure. This structure–function relationship is a foundation of many ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...

Investigators have created computer-generated models to bridge the gap between 'test tube' data about neurons and the function of those cells in the living brain. Their study could help in the ...

Biomolecular condensates were long believed to be simple liquid blobs inside cells. Researchers have now uncovered that some are actually supported by fine protein filaments forming an internal ...

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 ...

A new discovery inside your cells may change how scientists understand disease and design future treatments. Researchers have found a previously unknown structure in mammalian cells, something they ...

An essential component of the lymphatic system, the thymus, a pyramid-shaped organ located in the thoracic cavity, is responsible for producing T-cells. For centuries, the thymus was believed to be an ...
