Finding these post-common envelope systems that contain both a "dead" stellar remnant and "living" star -- otherwise known as white dwarf-main sequence binaries -- provides a unique way to investigate this extreme phase of stellar evolution.

"Our computational approaches further allowed us to identify and analyze these rare events that are not visible with standard sequencing assays."

Using single-cell sequencing and spatial mapping, the researchers specifically investigated breast epithelial cells.

Importantly, this doesn't change the actual DNA sequence itself.

Some newly identified sites actually occur in the coding sequence of the gene that becomes an mRNA.
