This technology has allowed researchers to study fleeting, ephemeral structures inside cells, which were previously undetectable. By utilizing cryo-electron tomography, the research team was able 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 have developed synthetic genes that function like the genes in living cells. The artificial genes can build intracellular structures through a cascading sequence that builds ...

All cells need to sense and respond to their environment—to know when to activate genes, build proteins and carry out their basic functions. One of the most well-studied cellular responses is how they ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...

In A Nutshell As cells age, they deliberately shrink a major internal structure called the endoplasmic reticulum. This downsizing happens early in adulthood and shifts cells away from protein ...

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 ...

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of ...

Hormones coordinate different body functions by carrying messages through the bloodstream to target cells and tissues. Hormonal imbalances occur through inadequate or excess hormone synthesis, which ...
