Mapping of the gene network that regulates glycan clock of ageing

A new study has identified three genes, MANBA, TNFRSF13B, and EEF1A1, as crucial in the regulation of IgG galactosylation, a trait associated with ageing. The research used GWAS to analyze IgG glycosylation phenotypes in a large sample size, increasing the understanding of this complex posttranslational modification.

Chern numbers of algebraic varieties

Dieter Kotschick solved Hirzebruch's problem, determining that most Chern numbers depend on algebraic structure of a variety, not topological properties. The breakthrough resolves the relationship between flexible and rigid geometric objects.
