Direct survival benefits in larger groups rather than kin-selected indirect fitness primarily drive the evolution of division of labor in cooperatively breeding vertebrates, particularly under harsh environmental conditions.
Analysis of scRNA-seq data from primate embryoid bodies highlights the value of cross-species comparisons for identifying and characterizing cell types, as marker genes can evolve fast.

Factoring out nucleotide-level mutation biases from antibody language models dramatically improves prediction of functional mutation effects while reducing computational cost by orders of magnitude.
The severity of active tuberculosis in a high-burden population is not explained by host or pathogen genetic variation, suggesting a dominant role for social and environmental factors.
