Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons ...

New research details the subcellular structures in neurons that enable signals to be transmitted from where they are received at specific sites on dendrites to the decision-making cell body located ...

Both images show individual red blood cells. The one on the right, produced by STED, more clearly shows the Piezo1 proteins (in green), which are a mechanical calcium channel and play a crucial role ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

That means researchers can now use it to better understand how genes function, how diseases start and how to design better treatments. "Every single cell can have a different chromosome structure," ...

Scientists have attempted to map the human cell since the first microscope was invented more than 400 years ago. But many components of the cell still remain uncharted. "We know each of the proteins ...

A feature of pancreatic cancer cells' surroundings determines whether they grow fast or become resistant to chemotherapy, a new study shows. The ability of these cancer cells to adapt quickly and ...

A Northwestern Medicine study has shed light on one of the most intricate construction projects in biology: how cells build and coordinate the internal scaffolding needed to create a healthy egg. The ...
