Theoretical morphospace reveals mixed optimisation of the avian wing planform for flight style - Nature Communications

Here, the authors examine bird wing planform shape and functional performance using theoretical morphospace and phylomorphospace. They find that, in a sample of 1138 extant bird taxa, planform shape i...

CD4+ T cells reactive to Epstein-Barr virus late lytic antigens are enriched in individuals with multiple sclerosis

CD4+ T cells in MS preferentially recognize EBV viral particles rather than latent antigens, and responses are reduced by B cell–targeting therapies.
