The molecular mechanisms that support life depend on the fate of small populations of molecules. The functions of biomolecules, however, are traditionally characterised through bulk-phase biochemical methods that only report on ensemble averages. Such methods are not sensitive to population heterogeneity or short-lived reaction intermediates. Single-molecule methods that allow for the direct observation of individual molecules have significantly advanced our understanding of biology in the past two decades. The goal of the work described in this PhD thesis was the development and use of single...

Researchers have uncovered a novel pathway that explains how cancer cells become resistant to chemotherapies, which in turn offers a potential solution for preventing chemo-resistance.

Scientists at the UNC School of Medicine have made the surprising discovery that a molecule called EdU, which is commonly used in laboratory experiments to label DNA, is in fact recognized by human cells as DNA damage, triggering a runaway process of DNA repair that is eventually fatal to affected cells, including cancer cells.

Knowing the structure of a complex biological system isn't nearly enough to understand how it works. It helps to know how the system moves.

A recent study reviewed the current progress on 3D interactions between host and viral genomes.
