A vaccine design approach that could protect against new variants of SARS-CoV-2 — the virus that causes COVID-19 — but also potentially protects against other coronaviruses is one step closer to reality as a result of research at Penn State College of Medicine. The scientists used areas of the SARS-CoV-2 virus that are less susceptible to mutation to engineer proteins called immunogens, which can elicit an immune response.

The textbook example of a virus which became less deadly in order to survive may have recently become more severe again.

The University of Florida Institute of Food and Agricultural Sciences has appointed entomologist and ecologist Matthew Thomas as director of the new Invasion Science Research Institute.

Traditionally, prenatal acetaminophen use has been considered to be safe, but new research shows it might impact sleep.

A common misconception is that viruses become milder over time as they become endemic within a population. Yet new research, led by Penn State and the University of Sydney, reveals that a virus — called myxoma —that affects rabbits has become more deadly over time. The findings highlight the need for rigorous monitoring of human viruses, including SARS-CoV-2, monkeypox and polio, for increased virulence.
