When you were first conceived, you were a single cell. From this basic fact, we can extrapolate a few things, most especially that all the cells that make up your body today came (indirectly) from ...

A human female is born with all the egg cells she will ever have. The possibility for the development of new oocytes is zero. Given this constraint, it is crucial that these gametes remain healthy and ...

The average human cell contains roughly 10,000 different proteins. Existing as several to millions of copies in each cell, proteins mediate all manner of tasks, including chemical transformations, ...

In two new studies, scientists at Oregon Health & Science University have uncovered detailed blueprints of how certain molecular "gates" in human cells work—findings that could open doors to new ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

Researchers can use it to test how well antiviral drugs work directly in living cells and see the results in real time. The team also points out that the same tool could be used to study how other ...

In a town on the shores of Lake Geneva sit clumps of living human brain cells for hire. These blobs, about the size of a grain of sand, can receive electrical signals and respond to them — much as ...

It has been claimed that because most of our DNA is active, it must be important, but now human-plant hybrid cells have been ...
