A biomimetic nanoreactor coated with senescent stem cell membranes delivers nitric oxide and magnesium while scavenging reactive oxygen species, reversing a vicious cycle of cellular aging and ...

Our cells' membranes have many functions. They not only provide mechanical protection but also precisely control which substances enter or leave cells. If they fail to perform these tasks, disease can ...

The cells of higher organisms such as mammals, flies and fungi enclose their genetic material in a nucleus. A nuclear ...

Cell death is rarely a tidy affair, but a newly proposed framework argues that one recently identified form of lytic cell ...

How do embryos develop? Why does the cortex of the mammalian brain fold? How do we feel touch at our fingertips? These and other fundamental biological questions remain unsolved. Yet, scientists know ...

Cell membranes play a crucial role in maintaining the integrity and functionality of cells. However, the mechanisms by which they perform these roles are not yet fully understood. Scientists have used ...

In a bid to better understand how cancer cells power their explosive growth and spread, scientists at Johns Hopkins Medicine say they have shed new light on the location and function of ...

Think back to that basic biology class you took in high school. You probably learned about organelles, those little “organs” inside cells that form compartments with individual functions. For example, ...
