Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, ...

The origin of the nucleus remains hotly debated among scientists, but new imaging and genomic data are shedding light on this billion-year-old mystery.

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is ...

Researchers have created an array of nanopillars that can breach the nucleus of a cell -- the compartment that houses our DNA -- without damaging the cell's outer membrane. This new 'gateway into the ...

Scientists at the Utrecht University in the Netherlands say they have identified a new way in which the toxic protein aggregates associated with Huntington’s disease may damage nerve cells and cause ...

Cells were long believed to safeguard nuclear contents, releasing them only during cell death. Extracellular DNA was thought ...

Our bodies are made up of countless cells, and each one is enclosed by a thin layer called the cell membrane. This membrane is not a rigid wall, but a soft, flexible sheet made of lipids. Beneath it ...

Scientists have uncovered an elegant biophysical trick that tuberculosis-causing bacteria use to survive inside human cells, a discovery that could lead to new strategies for fighting one of the world ...

Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has been out of reach. Subscribe to our newsletter for the latest sci-tech ...

Expansion microscopy reveals the structure of huntingtin aggregates inside the cell nucleus. Huntington’s disease is a devastating neurogenerative disorder caused by a mutation in the HTT gene that ...
