Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

Development of social learning and play in BaYaka hunter-gatherers of Congo

Scientific Reports, 2019
High-fidelity transmission of information through imitation and teaching has been proposed as necessary for cumulative cultural evolution. Yet, it is unclear when and for which knowledge domains children employ different social learning processes.

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

Advanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Late Pleistocene human genome suggests a local origin for the first farmers of central Anatolia

Nature Communications, 2019
Central Anatolia harbored some of the earliest farming societies outside the Fertile Crescent of the Near East. Here, the authors report and analyze genome-wide data from a 15,000-year-old Anatolian hunter-gatherer and from seven Anatolian and Levantine ...

Holocene Foragers and Interethnic Trade: A Critique of the Myth of Isolated Independent Hunter-Gatherers [PDF]

, 1991
It is popularly thought that today's existing hunter-gatherers lived until recently in isolation, independent of food-producing peoples. The present thesis takes a different view, proposing that middle-to-late Holocene foragers followed an economy based ...

The Beixin Culture archaeobotanical evidence from Guanqiaocunnan indicates a population dispersal of hunter-gatherercultivators into and across the Haida region of northern China [PDF]

, 2020
The Beixin Culture appears within the hilly southwestern area of the Haidai region of northern China at ca. 5000 BC, and spreads to its north and northeast flood plains in the following millennium, replacing the Houli Culture.

Polygenic adaptation and convergent evolution on growth and cardiac genetic pathways in African and Asian rainforest hunter-gatherers

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance The “pygmy” phenotype is a classic example of convergent adaptation in humans, having evolved independently in both African and Asian rainforest hunter-gatherers.

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Late Pleistocene human paleoecology in the highland savanna ecosystem of mainland Southeast Asia

Scientific Reports, 2021
The late Pleistocene settlement of highland settings in mainland Southeast Asia by Homo sapiens has challenged our species’s ability to occupy mountainous landscapes that acted as physical barriers to the expansion into lower-latitude Sunda islands ...
