A new tool called PRISM draws on virus-host interactions and a DNA repair pathway to help researchers visualize how cellular stress may contribute to neurodegenerative disease.
In both Drosophila and mosquitoes, protection lasts for generations following a single maternal exposure to positive-sense single-stranded RNA viruses.
Working with a virus that infects bacteria, the Stanford University biochemist and developmental biologist helped to develop a way to stitch DNA together, a discovery that gave rise to genetic engineering.
Emerging data as well as knowledge from the SARS and MERS coronavirus outbreaks yield some clues as to why SARS-CoV-2 affects some people worse than others.
Viruses that infect plants and occasionally insects appear to cause infection with a divide-and-conquer strategy, multiplying separate segments of genetic material in different host cells.
A case study reports evidence of viral replication lingering in the respiratory tract of an infected person, even after the person’s blood was Ebola free.
