Researchers identified and characterized a new cellular compartment in vertebrate cells that might be a precursor of today's eucaryotic nucleus. The study reveals that mammalian cells recognize, ...

Researchers at the Francis Crick Institute have shown that the 'pacemaker' controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...

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 ...

Fat is a normal and necessary part of the body. Fat cells store and release energy, as well as play significant roles in hormonal regulation and immunity. In recent decades, a concerning rise in ...

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 ...

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 ...

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 ...

(Nanowerk News) Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a ...

According to new research in the journal Immunity, T cells have a nuclear receptor doing something very odd - but very important - to help them fight pathogens and destroy cancer cells. This receptor, ...
