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 cell nucleus goes a long way during an immune response, both literally and figuratively. The white blood cells in question are cytotoxic T lymphocytes (CTLs), also known as killer T cells. These ...

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 ...

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 ...

Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic material (chromosomes) equally, and then rebuild the nuclear envelope around ...

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 ...

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 ...

The cell nucleus goes a long way during an immune response, both literally and figuratively. Subscribe to our newsletter for the latest sci-tech news updates. New research published in Science ...

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 ...
