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…
“This ensures that the daughter cell is born without age-related damage,” says professor Thomas Nyström from the Department of Cell and Molecular Biology. Thomas Nyström is a professor of microbiology at the University of Gothenburg and one of Sweden's leading researchers in the field of cellular and molecular biology. His research group has published countless scientific discoveries about cell ageing which have provided a new understanding of aging and age-related diseases. Now he and his colleagues have identified a key piece in the ageing puzzle….
The last ancestor we shared with worms, which roamed the seas around 600 million years ago, may already have had a sophisticated brain that released hormones…
