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 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 ...
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 ...
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 ...
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 ...
Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through narrow tissue structures, as in the case of metastasis. DNA would normally ...
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 ...
