Antigenic cartography using hamster sera identifies SARS-CoV-2 JN.1 evasion seen in human XBB.1.5 booster sera

The paper uses hamster sera to map antigenic differences among SARS-CoV-2 variants, showing JN.1 has significant antigenic divergence from XBB.1.5.

Cortical microtubules oppose actomyosin-driven membrane ingression during C. elegans meiosis I polar body extrusion

This study shows that CLS-2 and related kinetochore proteins stabilize cortical microtubules to limit membrane ingression and enable contractile ring assembly during C. elegans meiosis I polar body extrusion.

Post-vaccination Omicron infections induce broader immunity across antigenic space than prototype mRNA COVID-19 booster vaccination or primary infection

The paper compares antibody responses to different SARS-CoV-2 variants after vaccination and infection, finding that post-vaccination Omicron infection induces broader immunity than triple vaccination alone.

Active Surveillance Characterizes Human Intratumoral T Cell Exhaustion

The paper studies T cell exhaustion in human tumors using live-biopsy and two-photon microscopy, finding variable T cell speed and a link between motility and exhaustion state.

Learned adaptive multiphoton illumination microscopy

This paper develops a machine learning model to adaptively adjust multiphoton microscopy illumination power based on in situ cell imaging, enabling improved in vivo immune response visualization in mouse lymph nodes.
