In preclinical studies, spray offered nearly 100% protection from respiratory infections by COVID-19, influenza, viruses, and pneumonia-causing bacteria
Matrix metalloproteinases (MMPs) and their regulators, the tissue inhibitors of metalloproteinases (TIMPs), form an intriguing partnership. MMPs work by breaking down the dense matrix surrounding cells, freeing them to wander…
“Scientists have wondered for a long time why madness and creativity seem linked, particularly in artists, musicians, and writers,” notes Shelley Carson, a Harvard psychologist. “Our research results indicate that…
