The typical animal cell measures about 10 microns, or 0.001 centimeters, in diameter. Which is unsurprising—cells are small! that's sort of the point!—and, at the same time, curious. Animals ...

A newly found organelle, the hemifusome, helps manage cellular recycling. It may play a role in inherited diseases and open paths to new therapies. Scientists have identified a previously unknown ...

Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components.

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 ...
