Macrophage–Fibroblast Crosstalk Governs Tumor Mechanics, as Revealed by Spatiotemporal Force Mapping in 3D Spheroids

open access: yesAdvanced Healthcare Materials, EarlyView.
This study shows crosstalk among tumor cells, fibroblasts, and macrophages alters the physical forces inside 3D tumor spheroids. Incorporating deformable microparticles in 3D tumor spheroids, the researchers mapped mechanical stresses spatially and with respect to tumor growth (temporally).

Artemisinin‐Loaded Core‐Shell Microspheres Modulate Histone Lactylation to Remodel the Microenvironment for Cartilage Protection in Rheumatoid Arthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
ART@PLGA@GH‐A microspheres are developed via microfluidic technology for intra‐articular delivery of artemisinin. The system remodels rheumatoid arthritis microenvironments by regulating metabolic and inflammatory disorders, reducing lactate‐driven histone lactylation and cellular senescence, while restoring cartilage homeostasis and protecting joint ...

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

An Analysis of Intra-individual Variability in Criminal Propensity

open access: yes, 2012
Understanding criminal propensity requires reconciling two apparently contradictory dynamic patterns observed across studies. There is a general trend for criminal behavior to remain stable over time, and a general trend for it to fluctuate. The first pattern suggests that behavior is related to stable traits of the individual, while the second ...

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

open access: yesAdvanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Mapping causal links between prefrontal cortical regions and intra-individual behavioral variability

open access: yesNature Communications
Intra-individual behavioral variability is significantly heightened by aging or neuropsychological disorders, however it is unknown which brain regions are causally linked to such variabilities.
