Eukaryotic cells form the foundation of complex life, their defining feature being the presence of membrane-bound organelles. This article details the structure of eukaryotic cells and provides ...

Cells that control hunger have a strong influence on the brain’s higher cortical regions. The findings could lead to new treatments for psychiatric illness.

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 ...

Recent findings have shed light on the functions of centrosomes in animal cells and on the molecular mechanisms of centrosome assembly, in particular during mitosis.

Our cells produce a variety of proteins, each with a specific role that, in many cases, means that they need to be in a ...

It's no coincidence that our bodies feel a little creakier as we age. The trillions of cells that make up our skeleton age too, and some change in ways that weaken the very structure of our bones.

Essentials of Biology is a non-majors general biology course without a laboratory. The topics that will be covered include biological molecules, cell structure and function, cellular metabolism, cell ...

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.

Learn about white blood cells, which help your body fight inflammation and infections. A high or low white blood cell count may be associated with certain health conditions.

Transplanted chloroplasts endured two days inside animal cells—and got to work ...

Researchers have developed synthetic genes that function like the genes in living cells. The artificial genes can build intracellular structures through a cascading sequence that builds self ...
