People with SARS-CoV-2 antibodies may have low risk of future infection, study finds
People who have had evidence of a prior infection with SARS-CoV-2, the virus that causes COVID-19, appear to be well protected against being reinfected with the virus, at least for a few months, according to a new study. This finding may explain why reinfection appears to be relatively rare, and it could have important public health implications.

New experiences enhance learning by resetting key brain circuit
A study of spatial learning in mice shows that exposure to new experiences dampens established representations in the brain's hippocampus and prefrontal cortex, allowing the mice to learn new navigation strategies.

Human lung and brain organoids respond differently to SARS-CoV-2 infection in lab tests
Researchers are using stem cell-derived organoids to study how SARS-CoV-2 interacts with various organ systems. Their findings may help explain the wide variety in COVID-19 symptoms and aid the search for therapies.

Reactivating aging stem cells in the brain
As people get older, their neural stem cells lose the ability to proliferate and produce new neurons, leading to a decline in memory function. Researchers have now discovered a mechanism linked to stem cell aging - and how the production of neurons can be reactivated.
