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…
Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have uncovered new clues about the risk of cancer from…
In some cases, there's not much medics can do — a tourniquet won't stop bleeding from a chest wound, and clotting treatments that require refrigerated or…

Reproduction at old age involves risks that may impact ones’ own life and may impose reduced biological fitness on the offspring.
In large part, this highly regulated process of gene expression is what makes us fully functioning, complex beings, rather than a blob of like-minded cells.
MRSA are strains of the bacterium Staphylococcus aureus that are resistant to almost all antibiotics related to penicillin, known as the beta-lactams. Since…
