New images of canine parvovirus may help predict how virus jumps to new species
Canine parvovirus (CPV) is a highly infectious pathogen that causes severe diseases in unvaccinated dogs, including inflammation of the heart and acute gastrointestinal illness. Originating in cats, the virus is a rare example of a DNA-based virus that can jump between species, and a team of researchers’ discovery may help in predicting this and the virus’ ability to evolve, which could have implications for current vaccines used in dogs.

Regulating the ribosomal RNA production line
Cryo-electron microscopy study allows researchers to visualize structural changes in an E. coli enzyme synthesizing ribosomal RNA that shift it between turbo- and slow-modes depending on the bacteria’s growth rate

Altered 'coat' disguises fatal brain virus from neutralizing antibodies
A genetic modification in the ‘coat’ of a brain infection-causing virus may allow it to escape antibodies, according to Penn State College of Medicine researchers.

Determining how a coronavirus protein takes over human protein-making machinery
Jean-Paul Armache, assistant professor of biochemistry and molecular biology, has been awarded seed funding from the Huck Institutes of the Life Sciences at Penn State to use cryo-electron microscopy to study how an important SARS-CoV-2 protein binds to and takes over the human ribosome — a protein factory in the cell that the virus uses to copy itself.

New image of a cancer-related enzyme in action helps explain gene regulation
New images of an enzyme in action as it interacts with the chromosome could provide important insight into how cells — including cancer cells — regulate their genes.

Virus may jump species through 'rock-and-roll' motion with receptors
Like a janitor thumbing through a keychain to find just the right key to open a lock, the "rock-and-roll" motion of the canine parvovirus during the binding process may help explain how the virus can find the spot on a receptor to infect not just dogs, but multiple species, according to an international team of researchers.
