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 ...

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 ...

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 ...

Mitochondria are specialized structures within cells that are primarily responsible for energy production but that also play a key role in how cells respond and adapt to stress. When their function ...

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 ...

Tumors are stressful places for cancer-fighting immune cells. Low oxygen, high acid levels, and other stressors put strain on ...

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 ...
