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.

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 ...

A hunter-gatherer-farmer population model: Lie symmetries, exact solutions and their interpretation

, 2014
The Lie symmetry classification of the known three-component reaction-diffusion system modelling the spread of an initially localized population of farmers into a region occupied by hunter-gatherers is derived.

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 ...

Ancient human genomes suggest three ancestral populations for present-day Europeans [PDF]

, 2014
We sequenced the genomes of a 7,000-year-old farmer from Germany and eight 8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes¹-₄ with 2,345 contemporary humans to show that most present-day Europeans ...

Metabolic Reprogramming of T Cells by Dual UCP2 and IL‐17 Blockade Enhances Immunity Against Pancreatic Cancer

Advanced Science, EarlyView.
This study demonstrates that dual UCP2/IL‐17 blockade reprograms T‐cell metabolism to overcome PDAC immunosuppression. Genipin‐mediated UCP2 inhibition enhances CD8⁺ T‐cell IFN‐γ via IL‐12R/STAT4/mTOR signaling and mitochondrial OXPHOS. Combined IL‐17 depletion amplifies Tc1/Th1 responses, reduces MDSCs, and prolongs survival in PDAC models ...
