New study reveals how human astroviruses bind to humans cells and paves the way for new therapies and vaccines Human astroviruses are a leading viral cause of the stomach bug—think vomiting, diarrhea, and fever. It often impacts young children and older adults, leading to vicious cycles of sickness and malnutrition, particularly for those in low and middle income countries. It’s very commonly found in wastewater studies, meaning it’s frequently circulating in communities. As of now, there are no vaccines for…

The method, which involves treating carbon nanotubes with fluorine-based molecules, is reported in the Jan. 9 issue of the journal Science (Vol. 323 No. 234). The research was jointly led by Graciela B. Blanchet, a research fellow at DuPont, and George Malliaras, Cornell associate professor of materials science and engineering and the Lester B. Knight Director of the Cornell NanoScale Science and Technology Facility. Helen Lu, a research chemist at Dupont, and Mandakini Kanungo, a former Cornell postdoctoral fellow now at Xerox, also worked on the project. …
