The endoplasmic reticulum (ER) forms tight membrane contact sites (MCSs) with several organelles in animal cells and yeast. The function of MCSs between the ER and mitochondria and endosomes are ...

The prefrontal cortex region of the human brain is responsible for a range of complex functions from decision-making to certain types of memory. When something goes wrong in this part of the brain, it ...

Red blood cells transport oxygen throughout your body, including to vital organs and tissues. They also help your body get rid of carbon dioxide. Too little or too many red blood cells may be ...

Researchers have developed artificial cell-like structures using inorganic matter that autonomously ingest, process, and push out material - recreating an essential function of living cells. Their ...

White blood cells help your body fight inflammation and infections. A high or low white blood cell count may be associated with a number of short-term or long-term health conditions. White blood cells ...

More than a billion years ago a hungry cell devoured a tiny blue-green alga. But instead of the former simply digesting the latter, the duo struck a remarkable evolutionary deal. Now scientists are ...

The Saint Louis University Biology Department offers courses with hands-on learning opportunities from cellular structures to fish, birds, reptiles and mammals. Content below is provided by SLU ...

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, ...

A new discovery inside your cells may change how scientists understand disease and design future treatments. Researchers have found a previously unknown structure in mammalian cells, something they ...

A ribosome is a complex macromolecular structure in the cell which is involved in the process of translation. This is an essential function of all living cells, allowing for the production of proteins ...

As urban areas develop, each city forms a unique structural logic. With this structure usually conceived on an ad-hoc basis, political terms such as “metropolitan area” and “neighborhood” are not ...
