Chinese–US research partnerships outnumber all other international pairings. That trend, spurred by a long history of collaboration between the two countries, presents challenges, but the outcomes are a major boon for science.

Mammalian lifespans are dramatically diverse. Identifying the molecular signatures and underlying mechanism of longevity is of keen interest. Using comparative transcriptomics, Lu et al. (2022) showed that genes associated with maximum lifespan are regulated by circadian and pluripotency networks, which shed light on natural strategies for controlling lifespan.
