Behavior limits COVID-19 spread between University and community
Part of the collection of the Laboratory of Primatology and Paleontology at the University of Antananarivo, the jawbone that the team used in its study had originally been discovered at Beloha Anavoha in southern Madagascar. Carbon-14 dating, a commonly used method for determining the age of archeological artifacts of a biological origin, revealed that the M. edwardsi jawbone was about 1,475 years old.

In 2019, researchers from all 50 states and the District of Columbia participated in the first nation-wide mammal survey using standardized methods and a common data repository. This unprecedented and inaugural partnership provides novel insight into wildlife distribution and behavior across the entire country. IMAGE: DAN HERRERA, SNAPSHOT USA

A scanning electron microscope image showing SARS-CoV-2 (round gold objects), the virus that causes COVID-19, emerging from the surface of cells cultured in the lab. New research suggests that the experimental drug TEMPOL may be a promising oral antiviral treatment for COVID-19. The virus shown was isolated from a patient in the United States. The image was captured and colorized at NIAID's Rocky Mountain Laboratories in Hamilton, Montana. IMAGE: NATIONAL INSTITUTE OF ALLERGY AND INFECTIOUS DISEASES

In human brains, as global brain activity (blue) occurs, the arrows point to cerebral spinal fluid moving (orange and red). In these functional MRI images, the left brain demonstrates a weaker coupling, indicating Alzheimer's disease. A healthy coupling appears in the right images. IMAGE: XIAO LIU/PENN STATE

The researchers discovered that a location on canine parvovirus (CPV) where dog antibodies bind — called an antibody binding site — overlaps with a location on CPV where the virus attaches to cells — called a receptor binding site — in a fashion that is similar to SARS CoV-2 and influenza viruses. As a result, when antibodies attach to this antibody binding site on the virus, they prevent the virus from then attaching to and infecting cells. The image shows an antibody attached to CPV.
