Two new papers analyze fossils found in Canada and Kenya, respectively—vastly different environments for the preservation of ...

Proteins from an ancient rhino tooth unearthed in the Canadian Arctic have allowed scientists to look much deeper into the ...

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these ...

Researchers have described proteins that they say are among the most ancient ever sequenced. Two teams, which analysed ...

In 1991, the atomic-level structure of the most common of this protein type in human cells was determined: Like a molecular caterpillar, it consisted of two or more segments joined together, each ...

Study reveals how cells regulate repair protein production to prevent DNA damage over-repair or under-repair, aiding cell ...

Researchers have sequenced proteins from an ancient rhino relative from the cold, dry Haughton crater site (shown) in the ...

Next, other DNA repair proteins like FANCJ untie the G4 knot and cut the loop. Finally, the cell repairs the DNA to keep it healthy. This protects the genome and prevents damage that could harm ...
