Cells experience many different types of stress, such as starvation or stress caused by too much salt or too high a ...

Researchers have made a significant advancement toward understanding how the human genome is organized inside a single cell. This knowledge is crucial for analyzing how DNA structure influences gene ...

Around one million individuals worldwide become infected with HIV, the virus that causes AIDS, each year. To replicate and spread the infection, the virus must smuggle its genetic material into the ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Cancer cells with a cell nucleus that is easily deformed are more sensitive to drugs that damage DNA. These are the findings of a new study by researchers at Linköping University in Sweden. The ...

The discovery of a giant virus called Ushikuvirus offers inklings into the origin and evolution of our complex cells and new ...

Because viruses have to hijack someone else’s cell to replicate, they’ve gotten very good at it—inventing all sorts of tricks. A new study from two University of Chicago scientists has revealed how ...

Bone implants often fail to fully integrate with surrounding tissue, limiting their effectiveness in regeneration. A natural but often overlooked cellular process could hold the key to better outcomes ...

In order for HIV to replicate, the viral genome must enter into the cell nucleus and integrate into the host cell chromosome. Previous work suggests that the entry proceeds through nuclear pore ...

Biologists have long treated the cell as a chemical factory, but a new wave of research is forcing a rethink of that familiar ...
