The DNA in our cells wraps around proteins called histones to form nucleosomes, which organize into chromatin. This organization helps pack genetic material into the nucleus and influences how easily genes can be read and DNA damage repaired. Understanding how chromatin changes requires studying molecular movements and interactions that are difficult to capture experimentally.

Nitrogen fixation 'off switch' discovery could one day help crops make their own fertilizer
Nitrogen is essential for life. It's needed to build proteins, DNA and many other components of cells. Although nitrogen gas makes up almost 80% of Earth's atmosphere, most organisms cannot use it directly. Certain microbes solve this problem through a process called nitrogen fix

Scientists discover a human brain gene that can jump through DNA
Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile piece of DNA known as a trans
