This is a side note, but......In other words, another Earth might also be destined to collide with the real Earth and merge, disappearing shortly after life begins (or while it is in the middle of ...
Induced pluripotent stem cells have become one of the most powerful tools in modern biomedical research, offering scientists ...

Scientists have uncovered a molecular sequence that helps cells decide when to begin copying their DNA, revealing how a dormant replication machine is converted into an active engine for genome ...
Structural view of the MCM2-7 helicase with Sld3, Sld7 and Cdc45 bound at the site where Cdc45 is delivered. Structure derived from cryogenic electron microscopy data. Noguchi et al., 2026.
One of the most iconic visual representations in biological science is the double helix – the twisting, twin-stranded ladder that defines the shape of DNA molecules. But not all DNA follows this same ...
Researchers at the MRC Laboratory of Medical Sciences, in partnership with other institutions, have pinpointed the exact location where DNA begins to unwind as cells initiate the duplication of their ...
A newly mapped step in DNA replication suggests that strand separation begins at a precise junction between two helicase rings. Credit: Shutterstock Researchers mapped where DNA first opens and how a ...
Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment has been the focus of a 30-year research question. New work from the Crick ...
In turn, this slowed new DNA synthesis at replication forks, structures in which double strands of DNA separate to begin the copying process. The cells' attempt to restart the stalled replication fork ...
Balancing replication fork progression and origin usage is essential to maintain genome stability, but measuring replication fork progression rates and origin usage throughout the genome has been ...
