The highly infectious SARS-CoV-2 variant that recently emerged in South Africa, known as B.1.351, has scientists wondering how existing COVID-19 vaccines and therapies can be improved to ensure strong protection. Now, researchers reporting in ACS’ Journal of Medicinal Chemistry have used computer modeling to reveal that one of the three mutations that make variant B.1.351…
ROCHESTER, Minn. — Difficult-to-treat, chronic wounds in preclinical models healed with normal scar-free skin after treatment with an acellular product discovered at Mayo Clinic. Derived from platelets, the purified exosomal product, known as PEP, was used to deliver healing messages into cells of preclinical animal models of ischemic wounds. The Mayo Clinic research team documented…
Constantina Theofanopoulou wanted to study oxytocin. Her graduate work had focused on how the hormone influences human speech development, and now she was preparing to use those findings to investigate how songbirds learn to sing. The problem was that birds do not have oxytocin. Or so she was told. “Everywhere that I looked in the…

The new guidance on mask-wearing from the Centers for Disease Control and Prevention on Tuesday says that masks can be shed for some relatively safe outdoor activities, especially by fully vaccinated people, because the virus does not spread readily outdoors. But there are many circumstances where the new guidance still calls for masks to be…
