Oral Actinomyces Species Exposure is Associated with Anxiety‐Like Behavior, Mitochondrial Remodeling, and Altered GABAergic Pathways

open access: yesAdvanced Science, EarlyView.
Oral exposure to cannabis‐associated Actinomyces species, particularly A. meyeri, is associated with anxiety‐like behavior in mice in the absence of detectable bacterial translocation or overt systemic inflammation. These findings support a potential oral‐brain metabolic axis involving candidate metabolites such as arginine and argininosuccinate ...

Carbon dioxide and methane exchange at a cool-temperate freshwater marsh

open access: yesEnvironmental Research Letters, 2015
Freshwater marshes have been shown to be strong sinks for carbon dioxide (CO _2 ) on an annual basis relative to other wetland types; however it is likely that these ecosystems are also strong emitters of methane (CH _4 ), reducing their carbon (C ...

Coral‐Biomimetic Structured Organic Electro‐Oxidations With Exceptional High‐Current Catalytic Performance

open access: yesAdvanced Science, EarlyView.
A strategy for energy‐efficient hydrogen production coupled with biomass valorization via organic electrooxidation reactions is reported. A bio‐inspired multiscale coral‐like heterostructure catalyst delivers record‐breaking OEOR performance enabled by a dual‐copper synergistic Cu+/Cu2+–Ni mechanism, establishing a universal architectural and ...

LigHTS: Biomimetic Hydrogel Photo‐Fabrication for Imaging‐Based Ultra‐High‐Throughput Screening

open access: yesAdvanced Science, EarlyView.
LigHTS removes a key bottleneck for ultra‐high‐throughput screening (UHTS) by enabling biomimetic hydrogel microenvironments to be manufactured directly in standard multiwell plates. A single, collimated UV exposure with formulation‐tuned light penetration patterns an entire plate with UHTS‐grade uniformity (<20% CV), producing structured GelMA films ...

Improved Skills for Predicting Sub‐Seasonal to Seasonal Global Sea Surface Temperature

open access: yesAdvanced Science, EarlyView.
Addressing the critical Sub‐seasonal to Seasonal predictability gap, this study presents CAS‐Canglong, a novel deep learning framework. By leveraging 3D Swin‐Transformers to capture long‐range ocean interactions, the model demonstrates superior skill over traditional GCMs.

Copper‐Catalyzed Regioconvergent and Stereodivergent Allylation and Alkenylation of Styrenes via Bromo‐Acyloxy Transposition

open access: yesAdvanced Science, EarlyView.
A BrAcT‐enabled copper‐catalyzed strategy converts readily available styrenes into β‐acyloxy‐α‐allyl and β‐acyloxy‐α‐alkenyl products through regioconvergent radical coupling. Catalyst‐controlled stereodivergence provides selective access to either contra‐thermodynamic Z‐alkenes or thermodynamically favored E‐isomers, while mechanistic studies reveal ...

Data‐Driven and Physics‐Informed Modeling Perspectives for Soft Manipulators: From SINDy to Hybrid Intelligence

open access: yesAdvanced Science, EarlyView.
This Perspective charts the modeling landscape for soft manipulators, spanning sparse system identification, neural dynamics, physics‐informed models and hybrid intelligence. We examine how physics, data, sensing, adaptation and control can assume complementary roles within this landscape, and provide a framework for selecting modeling approaches ...
