Researchers have developed a bioengineered chewing gum that may offer a new way to target microbes associated with head and neck cancer. In tests involving oral samples from patients, extracts from the gum sharply reduced one virus and two types of bacteria linked to the disease. The research team was led by Henry Daniell of the School of Dental Medicine at the University of Pennsylvania. The findings were published in Scientific Reports and could support the development of more accessible and a...
