Divergent Responses of Bacterial Communities to Permafrost Degradation and Their Associations With Carbon Across Vertical Profiles

open access: yesAdvanced Science, EarlyView.
Bacterial α‐diversity decreases, but stochasticity and community stability increase across the 15 m‐depth vertical profiles and along the degraded gradient within the active layer. The abundance and interaction of core taxa mainly control community stability in the active and permafrost layers, respectively.

Genomics Insights Into High‐Latitude Adaptation of Tibetan Macaques

open access: yesAdvanced Science, EarlyView.
Tibetan macaques exhibit unique adaptations to cold, high‐latitude environments, including shortened tails and enhanced fat storage. Genomic analyses reveal a species‐specific TBX6 mutation linked to tail reduction and selection on lipid metabolism genes.

STUDY ON THE MECHANISM OF INFLUENCE OF INTERNAL GEAR RING FLEXIBILITY ON THE BIAS LOAD BEHAVIOR OF AERONAUTICAL PLANETARY GEAR SYSTEM

open access: yesJixie qiangdu
The planetary gear system is widely used in aircraft transmission equipment because of its small size, light weight and large load capacity,but the problem of bias load caused by various errors cannot be avoided, and a serious bias load condition will ...

Intertidal Warfare: Synergistic Allelopathy Mediates Spatial Competition between Two Marine Calcareous‐Shelled Sessile Organisms

open access: yesAdvanced Science, EarlyView.
This study reveals a hidden chemical weapon among calcareous‐shelled sessile organisms in the intertidal zone: the barnacle Balanus albicostatus releases a synergistic blend of palmitic acid and 1‐palmitoyl‐sn‐glycero‐3‐phosphocholine as the allelochemical with the inhibitory activity against attachment of the mussel Vignadula atrata, which may mediate

Plant Robotics for Sustainable and Environmentally Friendly Robots: Insights from Actuation Characteristics

open access: yesAdvanced Science, EarlyView.
Plants are promising materials for building sustainable and eco‐friendly robots due to their inherent multifunctionality, with actuation playing a crucial role. This article focuses on the physical movements of plants and, from the perspective of actuation characteristics, explores representative plant species and their behaviors, the current state of ...
