From middle school biology we were always taught that the nucleus is the “control center” of the cell, similar to how the brain is the control center of our own bodies. At first glance this makes a ...

The white blood cells in question are cytotoxic T lymphocytes (CTLs), also known as killer T cells. These "warrior" cells work to kill off infected or cancerous cells in what is both a quick yet ...

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 ...

Researchers at the Francis Crick Institute and King's College London have discovered that how soft or rigid proteins are in certain regions can dictate how fast or slow they enter the nucleus.

A new study has revealed how HIV squirms its way into the nucleus as it invades a cell. Because viruses have to hijack someone else's cell to replicate, they've gotten very good at it -- inventing all ...

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 ...

Humans aren’t the only targets for viruses. Like us, bacteria become infected by many types of viruses. In fact, across billions of years, bacteria and viruses have engaged in a non-stop evolutionary ...

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 ...
