For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like ...

Images and videos of embryo modelsFor the first time, stem cells typically considered restricted to forming body tissues spontaneously formed a ...

Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...

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, ...

Fibroblasts are an essential component of the heart, as they play key roles in its structure, development and response to ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of ...

Combining hyperspectral imaging and AI, this research identifies oxidative stress in red blood cells, paving the way for ...

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 earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

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 ...
