Malignant cells adopt a different pathway for genome duplication

Genomes must be replicated in two copies during cell division. This process occurs at structures called 'replication forks', which are equipped with enzymes and move along the separated DNA strands. In tumour cells, the replication ...

Spirals of light may lead to better electronics

(Phys.org) —A group of researchers at the California Institute of Technology (Caltech) has created the optical equivalent of a tuning fork—a device that can help steady the electrical currents needed to power high-end ...

Tumors elude anti-cancer drugs through 'fork reversal' repair

In research recently published in Nature Structural & Molecular Biology, Alessandro Vindigni, Ph.D., associate professor of biochemistry and molecular biology at Saint Louis University, discovered how cancer cells respond ...

Are our textbooks wrong? Astronomers clash over Hubble's legacy

Edwin Hubble's contributions to astronomy earned him the honor of having his name bestowed upon arguably the most famous space telescope (the Hubble Space Telescope, HST). Contributions that are often attributed to him include ...

Dual systems key to keeping chromosomes intact

USC scientists have discovered how two different structural apparatuses collaborate to protect repetitive DNA when it is at its most vulnerable – while it is being unzipped for replication.
