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 ...

Cells contain various specialized structures -- such as the nucleus, mitochondria or peroxisomes -- known as 'organelles'. Tracing their genesis and determining their structure is fundamental to ...

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, ...

Researchers examined anatomy of neurons from humans, mice and fruit flies. They discovered that the cellular structure of the brain is at a critical point, poised between two phases. New insights ...

Cells rely on biomolecular condensates to coordinate essential biological processes without surrounding membranes. These droplet-like dynamic assemblies control the way in which DNA is turned into ...

In a recent study published in the journal Nature, a large team of researchers from the United States (U.S.) used single-cell ribonucleic acid (RNA) sequencing combined with high-resolution ...

Researchers at the Icahn School of Medicine at Mount Sinai have characterized how cellular senescence—a biological process in which aging cells change how they function—is associated with human brain ...
