Genomics and social practices at Mogou and other Gansu sites during prehistoric trans-Eurasian exchange

Ancient DNA from 149 individuals at 11 sites in Gansu, China, dated to around 4,700–3,000 years ago, reveals human population history during early transcontinental exchanges of agriculture and technology, as well as contemporary social practices, at the large Mogou cemetery.

Phages communicate across species to shape microbial ecosystems

Gallego-del-Sol et al. show that arbitrium-coding phages can sense non-cognate peptide signals from other phages to regulate lysis-lysogeny decisions. This crosstalk affects lysis-lysogeny outcomes of phage infections, mixed lysogenic communities, and polylysogens. Our results demonstrate that crosstalk is an important mechanism that drives phage interactions in microbial communities.

Metabolite-gated vascular contractility switch: OXGR1 activation mechanism enables agonist therapy for rosacea erythema

Xiao et al. identify α-KG as a rosacea-associated metabolite that activates the OXGR1-Gq-MYL9 axis in the vascular smooth muscle cells to boost contractility and suppress pathological vasodilation underlying erythema. Cryo-EM reveals a bipartite-acid pocket of OXGR1 that enables structure-guided development of A-1, a selective agonist that alleviates erythema in rosacea-like models.

Editing strigolactone hormone receptor for robust antiviral silencing in rice

Precise genome editing of the rice strigolactone receptor DWARF14 confers robust, transgene-free antiviral resistance by blocking viral suppression of endogenous RNA silencing, offering a promising strategy for durable disease protection without a yield penalty.
