In this study, Qian et al. identify a crosstalk between branched-chain amino acid metabolism and cell growth and motility through RhoC. Their work shows how enhanced BCAT1 activity, as identified by a mutation enriched in gastric cancer, leads to increased production of a metabolite that activates RhoC signaling.

How Akt pathway is activated under stress is poorly understood. Here, the authors demonstrate the crucial role of AMPK for cellular stresses and growth factors- mediated Akt activation through a mechanism involving the E3 ubiquitin ligase Skp2 and Cullin-1.

DNA methylation data of whole blood from Han Chinese individuals are used to map mQTLs, finding that cis- and trans-mQTLs show distinct patterns of East Asians (EA) ancestry-specific colocalization with complex trait variation.

Driven by dynamic covalent and coordinate bonding, hierarchical components are formed in situ and assembled in an ordered manner, yielding highly crystalline supramolecular nanotubular frameworks and tubular covalent organic frameworks.

Low-frequency quasiperiodic oscillations in X-ray data are thought to trace the accretion flow in X-ray binaries. Here, the detection of 200 keV oscillations probes the innermost regions of MAXI J1820+070, revealing the precession of a small-scale jet.

The reconstitution of gentamicin B biosynthesis reveals the existence of multiple new intermediates and branching pathways and enables the identification of factors that contribute to the low levels of the natural product in the native producer.

Exceptional alpine plant diversity exists in the Hengduan Mountains. Here, through genome assembly and population genomics studies, the authors find notable intraspecific divergence among Cushion willow populations isolated by the sky island-like habitats and consider it contributes to speciation and biodiversity.
