Neural network fills in data gaps for spatial analysis of chromosomes

Computational methods used to fill in missing pixels in low-quality images or video also can help scientists provide missing information for how DNA is organized in the cell, computational biologists at Carnegie Mellon University ...

An easier way of sneaking antibodies into cells

For almost any conceivable protein, corresponding antibodies can be developed to block it from binding or changing shape, which ultimately prevents it from carrying out its normal function. As such, scientists have looked ...

Cell chemistry illuminated by laser light

Raman microspectroscopy is a laboratory technique to produce molecular fingerprints of materials and biological specimens. However, to date fluorescence has interfered with effective application of this technique and limited ...

Elusive cancer-related protein captured in flight

Scientists have for the first time seen how the MYC protein, which plays a central role in cancer, binds to a key protein and controls important functions in the cell. The study, published in Nature Structural and Molecular ...

Study tracks evolutionary history of metabolic networks

By analyzing how metabolic enzymes are built and organized, researchers have reconstructed the evolutionary history of metabolism. Their study shows how metabolic networks—which drive every cellular process from protein ...

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.
