Climate frameworks for the Middle Stone Age and Later Stone Age in Northwest Africa
Quaternary InternationalThis paper examines climate conditions in Northwest Africa for Marine Isotope Stage 4, 3, and 2 (71,000–11,000 years ago) and their impact on the distribution of potential suitable areas on a regional scale. The analysis uses climate simulations to model: 1) the geographical extent and variability of macro-refugia based on ethnographic data; and 2) the

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion
Advanced Robotics Research, EarlyView.A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Ovarian Matrisome Dynamics and αvβ3‐Mediated Regulation in Early Follicular Development
Advanced Science, EarlyView.The matrisome undergoes dynamic remodeling during early follicular development. Integrin αvβ3 mediates matrisome signals, regulating primordial follicle activation/atresia and secondary follicle growth via Hippo/mTOR pathways, with conserved roles in human ovaries, offering therapeutic targets for ovarian disorders.

RETREG1‐Mediated Reticulophagy is Essential for Dendritic Cell Maturation and Function in Sepsis
Advanced Science, EarlyView.Reticulophagy regulator 1 (RETREG1) maintains dendritic cell (DC) maturation and function in early sepsis. Mechanistically, activating transcription factor 6 (ATF6) acts as a direct transcription factor regulating RETREG1 expression in response to sepsis‐induced endoplasmic reticulum (ER) stress.
