Bacterial genome is regulated by an ancient molecule

We are all collections of cells, each cell containing the instructions—our DNA—to become any other cell. What differentiates a heart cell from a skin cell from a brain cell is the expression—or silencing—of genes.

Landmark advancement in flow cytometry technology

Becton, Dickinson and Company, a global medical technology company, today announced that a study conducted in collaboration with the European Molecular Biology Laboratory (EMBL) and published as the cover story of the January ...

The membrane structure of inner ear protein prestin is revealed

As mammals, we have very sensitive hearing, thanks to a process known as cochlear amplification. This amplification is down to sensory cells in the inner ear called outer hair cells (OHCs), and it is thought to depend on ...

'Simple' bacteria found to organize in elaborate patterns

Over the past several years, research from University of California San Diego biologist Gürol Süel's laboratory has uncovered a series of remarkable features exhibited by clusters of bacteria that live together in communities ...

Missing 'key' could overcome drug discovery barrier

Scientists have found a missing 'key' that unlocks critical channels responsible for potassium ions to flow across cell membranes in a process that is essential for life. The discovery overcomes a major barrier to the development ...

Cell biology

Cell biology (formerly cytology, from the Greek kytos, "container") is an academic discipline that studies cells – their physiological properties, their structure, the organelles they contain, interactions with their environment, their life cycle, division and death. This is done both on a microscopic and molecular level. Cell biology research encompasses both the great diversity of single-celled organisms like bacteria and protozoa, as well as the many specialized cells in multicellular organisms like humans.

Knowing the components of cells and how cells work is fundamental to all biological sciences. Appreciating the similarities and differences between cell types is particularly important to the fields of cell and molecular biology as well as to biomedical fields such as cancer research and developmental biology. These fundamental similarities and differences provide a unifying theme, sometimes allowing the principles learned from studying one cell type to be extrapolated and generalized to other cell types. Hence, research in cell biology is closely related to genetics, biochemistry, molecular biology and developmental biology.
