Researchers at the University of Geneva have developed a technique that enables visualization of cellular organelles at a resolution that has not previously been achievable in optical microscopy.

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, ...

Although known since the 1830s as a round, dark spot in a cell's nucleus, only recently has the nucleolus gotten its full due. Scientists have learned that besides building a cell's protein factories, ...

BUFFALO, N.Y. -- In cells, numerous important biochemical functions take place within spherical chambers made from proteins and RNA. These compartments are akin to specialized rooms inside a house, ...

Our body is made up of many different kinds of cells, and inside each cell are organelles, tiny machines that help carry out cellular functions. New work reveals more about a network connecting two ...

Two studies by scientists at the University of Chicago have demonstrated a new way to look into the inner workings of cells—in particular, to track the flow of ions inside the many tiny organelles ...

Inside of cells, organelles perform specialized functions to keep biological functions moving, one of which is the ribosome. Ribosomes are tiny machines known for making proteins. Another organelle is ...

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 ...

One way biological compounds inside cells stay organized is through membrane-less organelles (MLOs) -- wall-less liquid droplets made from proteins and RNA that clump together and stay separate from ...

The functional morphology of the mouth apparatus for the suspension-feeding tetrahymenine ciliate Glaucoma was analyzed from a series of SEM photographs in conjunction with studies on feeding currents ...

Type III secretion systems (T3SSs) are protein transport nanomachines that are used by numerous important Gram-negative bacterial pathogens and symbionts to establish trans-kingdom interactions with ...
