Largest viral-protein library gives researchers new way to probe emerging pathogens

To prevent viruses from sickening or killing us—whether it's an individual case of hepatitis B or a COVID pandemic—it's crucial to understand how the proteins they make initiate changes in our bodies that allow them to flourish. A new tool has broadened the scale at which researchers can study these proteins, promising to speed basic discoveries in virology, inform the development of new vaccines and treatments, and help humanity protect against emerging pathogens.
