Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

Declines of Aerial Insectivores in North America Follow a Geographic Gradient

Avian Conservation and Ecology, 2010
North American birds that feed on aerial insects are experiencing widespread population declines. An analysis of the North American Breeding Bird Survey trend estimates for 1966 to 2006 suggests that declines in this guild are significantly stronger than

Origin of Dark Current Robustness in Photomultiplication Organic Photodetectors Enabled by Ionic Conjugated Electron‐Blocking Layers

Advanced Materials, EarlyView.
Ionic conjugated polyelectrolyte electron‐blocking layers enable photomultiplication organic photodetectors with dark current robustness up to −10 V and external quantum efficiencies exceeding 3000%. Fowler–Nordheim tunneling, interfacial dipole, trap density of states, and noise analyses reveal how ionic conjugated polyelectrolytes suppress electron ...

Data‐Driven Materials Science for Energy‐Sustainable Applications

Advanced Materials, EarlyView.
Data‐driven approaches powered by artificial intelligence are transforming materials discovery for energy sustainability. This review examines how auto‐generated high‐quality materials databases and domain‐specific language models accelerate research in photovoltaics, thermoelectrics, batteries and magnetic materials. Applications involve extraction of

Do Striped Hyenas Have a Sweet Tooth? First Evidence of Honey Consumption by a Hyaenid

Ecology and Evolution
Dietary flexibility in carnivores remains an underexplored aspect of their ecology, particularly the consumption of non‐meat foods. While striped hyenas (Hyaena hyaena) are primarily scavengers, they are known to occasionally consume plant material ...

A Universal van der Waals Tunneling Injector for Monolayer CMOS

Advanced Materials, EarlyView.
A universal van der Waals injector unlocks polarity‐flexible tunneling contacts for monolayer CMOS. SnSe2, an intrinsically degenerate 2D semiconductor, establishes polarity‐specific band alignments with both WSe2 and MoS2 channels, enabling steep switching, high on/off ratios, and a unified route to low‐power 2D logic.

Integrating counts from rigorous surveys and participatory science to better understand spatiotemporal variation in population processes

Methods in Ecology and Evolution
Knowledge of variation in population processes (e.g. population growth) across broad spatiotemporal scales is fundamental to population ecology and critical for conservation decision‐making. Count data from rigorous surveys (e.g.

Thinning effects and underlying pathways for birds of conservation concern in New Mexico piñon-juniper woodlands

Avian Conservation and Ecology
Piñon-juniper woodlands are one of the largest ecosystems in the United States and harbor many piñon-juniper-associated bird species. It is a common practice to reduce tree cover and density of these woodlands for various objectives, including increasing
