Autonomous and Communicative Microcapsule Systems for Life‐Like Homeostatic pH Regulation

open access: yesSmall, EarlyView.
A dual‐microcapsule system mimicking biological homeostasis is developed, enabling programmable pH oscillations through antagonistic enzymatic feedback. Monodisperse urease and esterase capsules, produced via hybrid‐junction 3D‐printed microfluidics with epoxy‐modified channels, exhibit adaptive shell permeability and inter‐capsule communication.

Outer‐Sphere Tuning of Synthetic Iron–Sulfur Clusters Within Nanoscale Cage Frameworks

open access: yesSmall, EarlyView.
Noncovalent encapsulation of a synthetic iron–sulfur cluster within hydrophobic, naphthalenediimide (NDI)‐paneled cages is shown to lead to dramatic changes in the electronic structure and covalency of the Fe─S core. ABSTRACT As atomic‐scale archetypes for multi‐electron transfer, iron–sulfur clusters are compelling candidates for the design of redox ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

open access: yesSymbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Staging concept for aging management: Definition, mechanism, and coping strategies

open access: yesVIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Rendezvous in Space: Tech Diplomacy and the Commercial Space Era—A Study of Rendezvous and Docking Technologies and Space Exploration Co‐Operation Since the Cold War

open access: yesGlobal Policy, EarlyView.
ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

Late Holocene moisture variability in Arctic Alaska from chitin δ18O

open access: yesBoreas, EarlyView.
Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute

Unveiling Gut Homeostasis Disruption in Sepsis: Towards an Integrated Mechanistic and Translational Roadmap

open access: yesCell Proliferation, EarlyView.
Elucidating the contribution of gut‐organ axes will provide new insights for developing combined therapeutic strategies against sepsis‐associated multiple organ dysfunction. ABSTRACT Sepsis, a life‐threatening clinical syndrome precipitated by a maladaptive host response to infection, is associated with substantial morbidity and high mortality rates ...
