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 human olfactory system possesses a special electric amplification mechanism that enables olfactory cells to respond even to extremely weak stimuli. Scientists at Heidelberg University headed by physiologist Prof. Dr. Stephan Frings have now established how this mechanism works. Crucial is the role played by chloride ions stored in the sensory cilia of the nose. As soon as the olfactory receptors in the sensory cilia detect odorants, the chloride ions are immediately discharged. This process generates strong electric signals that pass on the relevant olfactory information to the brain. …
