Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of ...

A team of Israeli researchers has found that one of the reasons that sleep could be so important to animals — including humans — is that it takes neurons 'offline' so DNA damage accumulated during ...

One of the challenges of working with ancient DNA samples is that damage accumulates over time, breaking up the structure of the double helix into ever smaller fragments. In the samples we’ve worked ...

Gene expression is controlled, in part, by the interactions between genes and regulatory elements located along the genome.

Researchers identify a novel centromere-specific histone H3 variant called the “CENP-A”, which reconstituted with H4 forms “CENP-A–H4” octasome and explore its role in mitosis. Centromeres, ...
