Using ESA's XMM-Newton and NASA's NuSTAR space telescopes, astronomers have observed a nearby active galaxy known as NGC 7582. Results of the observational campaign, published March 30 on the arXiv pre-print server, shed ...
The DNA molecule is located in the cell nucleus as a densely packed complex of DNA and protein, known as chromatin. Wrapped in sections around a core of special proteins known as histones, the DNA forms so-called nucleosomes, ...
