New research suggests early warning signals (EWSs) could help in the monitoring of disease outbreaks, such as COVID-19. The study found warnings could be detected weeks earlier than any rapid increase in cases. The findings could help governments and policy makers improve the accuracy of their decisions and allow timely interventions if needed. from Top Health News -- ScienceDaily https://ift.tt/3DvxDk4 via IFTTT
UV light damages the DNA of skin cells, which can lead to cancer. This process is counteracted by the DNA repair machinery. It has been unclear, however, how repair proteins work on DNA tightly packed in chromatin, where access to DNA damage is restricted by protein packaging. Using cryo electron microscopy, researchers from the Thomä group at the FMI have identified a new mechanism whereby repair proteins detect and bind to damaged densely packed DNA.
