Here, Wang et al. show that the hepatokine Tsukushi is upregulated in obesity and inhibits sympathetic activity and thermogenesis in fat by promoting whitening.

Polygenic risk scores can help identify individuals at higher risk of type 2 diabetes. Here, the authors characterise a multi-ancestry score across nearly 900,000 people, showing that its predictive value depends on demographic and clinical context and extends to related traits and complications.
