Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment.

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 ...

Cryo-electron tomography shows what molecules look like in high-resolution – in this case, the virus that causes COVID-19. Nanographics, CC BY-SA All life is made up of cells several magnitudes ...

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

If scientists could shrink themselves to microscopic size and take a journey through the human body—like the submarine crew ...

Temporarily disabling a protein complex that organizes DNA into loops inside the cell's nucleus drastically disrupted the ...

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 ...

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, ...

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 ...

Jasmine Plummer shares the spatial omics techniques she has developed to investigate the cellular processes underlying ...

What does it take to be a super athlete? Take a close-up look at cells, tissues, and organs to see if their biology gives them an advantage.
