Over a year into the pandemic, animal providers have been working to meet changing demand for the animal models needed to study SARS-CoV-2

The SARS-CoV-2 pandemic has significantly increased the demand for rhesus macaques, which might outstrip the supply for COVID-19 research and for other biomedical research studies. Baboons, another well-characterized research primate model, should be considered as a promising alternative for COVID-19 disease studies.

New probes are letting neuroscientists record neuronal activity over larger areas and longer time periods

Social isolation can lead to poor mental and physical health. A new study determines that social isolation increases food and nicotine-seeking during abstinence, but that social housing can reverse these effects.

In this perspective, the authors discuss the use of Caenorhabditis elegans as a model system to study host–microbe interactions, highlighting innovative methodologies and key findings from recent studies.
