  • 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.

  • From melody to language

    In the process of developing language, the melody patterns that emerge in infants' vocalizations are a very important first step. A new study has shown that the complexity of these patterns rapidly increases in the first months.
