The effect of circulating neutralizing antibodies on the replication of SARS-CoV-2 variants following post-vaccination infections.

This study examines how pre-existing neutralizing antibodies affect viral shedding in post-vaccination SARS-CoV-2 infections, finding that higher titers reduce viral load and duration but are less effective against Omicron variants.

Genetic architecture and evolution of color variation in American black bears

This study identifies a missense mutation in TYRP1 responsible for the cinnamon color morph in American black bears and traces its evolutionary origin and spread.

Tension anisotropy drives phenotypic transitions of cells via two-way cell-ECM feedback

This study shows that tension anisotropy, not stress amplitude, drives phenotypic transitions of fibroblasts to myofibroblasts through cell-ECM feedback.

Microstructured hydrogels to guide self-assembly and function of lung alveolospheres

This paper introduces a hydrogel-based method to culture lung alveolospheres without Matrigel, reducing heterogeneity while maintaining cell fate.

Interrupting reactivation of immunological memory reprograms allergy and averts anaphylaxis

The paper uses single-cell RNA-sequencing to identify IL-4/IL-13 as critical for IgE recall in peanut allergy and shows blocking this pathway prevents anaphylaxis.

Intermittent Starvation Extends the Functional Lifetime of Primary Human Hepatocyte Cultures

This study shows that intermittent starvation extends the functional lifespan of primary human hepatocyte cultures, improving drug toxicity testing and metabolic function.
