Hierarchical Targeting of TREM2+ Myeloid Cells via Acid‐Triggered OMVs Reprogram Immunosuppression and Suppress Osteolysis in Bone‐Metastatic TNBC

open access: yesAdvanced Science, EarlyView.
This study developed a hierarchical targeting nanoplatform, siTREM2@ETP‐PEOz‐OMVs, against triple‐negative breast cancer (TNBC) bone metastasis. It precisely delivers therapeutic siTREM2 to monocytes/macrophages within the metastatic niche. This intervention dually regulates cell fate: reprogramming immunosuppressive macrophages and inhibiting ...

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

open access: yesAdvanced Science, EarlyView.
Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.

Isosteric Substitution Enables Rational Design of Two‐Dimensional Energetic Crystals

open access: yesAdvanced Science, EarlyView.
Isosteric substitution transforms a classical nitro–amine motif into two‐dimensional aminofurazans with performance beyond TATB. ABSTRACT Two‐dimensional (2D) energetic crystals dissipate mechanical insult via interlayer slip, yet their molecular design space remains narrow.
