A new organelle has been discovered in human cells — and scientists call it a "hemifusome." Like the full-size organs in our bodies, the organelles within cells are specialized structures that carry ...

Hemifusomes are fused vesicles, or sacs of fluid, that were previously unknown to exist inside cells. They were discovered using cryo-electron tomography, which literally freezes them in time, and ...

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, ...

Hyperspectral imaging has provided an insight into how cells organize and prioritize organelle growth. As cells grow, their organelles also need to grow. But do all the organelles grow at the same ...

Cells behave like cities and organelles carry out infrastructural roles: mitochondria are powerhouses, the endoplasmic reticulum serves as a transport hub and lysosomes help with waste disposal.

Picture a living cell as if it were a city. If you were the urban planner for this (very little, very alive) city, one of the things you would have to decide is how to allocate space for different ...

Even after decades of peering into cells, biologists are still finding surprises. In a twist, researchers at the University of Virginia and the National Institutes of Health uncovered a new organelle, ...
