  • A study quantifying the neutralization of severe acute respiratory syndrome coronavirus 2 variants in individuals infected with Omicron/BA.1 shows that vaccinated individuals previously infected with Omicron have enhanced protection against reinfection with current variants, \including Omicron/BA.2, while Omicron/BA.1 infected unvaccinated individuals have limited protection.

  • Addressing nutrition and climate resilience together requires transdisciplinary participatory action research with clear impact pathways for systems change that starts from the ground up. The concept of ‘crops that nourish’ is proposed here to offer a new mode of pursuing agricultural development. It involves iterative co-creation between farmers and researchers that prioritizes local needs and agency, human health, resilience and sustainability through a focus on opportunity crops.

  • Cross-neutralization assays of early variants and the 501Y.V2 variant of SARS-CoV-2 show that plasma from individuals infected with 501Y.V2 effectively neutralizes all variants, indicating that a vaccine that targets 501Y.V2 may also be effective against other SARS-CoV-2 variants.

  • Intranasal oxytocin can affect brain function either by direct entry to the brain or by increasing oxytocin levels in blood plasma. Here, the authors show that increases in plasmatic oxytocin account for some but not all of the changes observed following intranasal oxytocin administration.

  • Plasma from individuals vaccinated with BNT162b2 exhibits 22-fold less neutralization capacity against Omicron (B.1.1.529) than against an ancestral SARS-CoV-2 strain but residual neutralization is maintained in those with high levels of neutralization of ancestral virus.
