Paraborg: Paramedic Cyborg Insects for In Situ Emergency Drug‐Delivery

Advanced Science, EarlyView.
This work introduces Paraborg, a human‐supervised paramedic cyborg‐insect platform that combines controllable locomotion, onboard imaging, and an auto‐injection mechanism for in situ drug‐delivery. By demonstrating reliable navigation, target stabilization, injector launch, and multi‐insect teamwork, the study extends cyborg insects from survivor ...

Development of a spark discharge model for predicting ignition stability in high EGR conditions in SI engines

Nihon Kikai Gakkai ronbunshu
Recently, EGR (Exhaust Gas Recirculation) combustion has been used to enhance the thermal efficiency of internal combustion engines. However, EGR combustion causes ignition instability, leading to increased cycle-to-cycle combustion variability and ...

Multi‐Scale Bionic Structure Constructs Biomass Flame‐Retardant Thermal Insulation Foam Material

Advanced Science, EarlyView.
Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...

Advances in Computational and Experimental Approaches to Chemical Short‐Range Order Formation in Multi‐Principal Element Alloys

Advanced Science, EarlyView.
Chemical short‐range order (CSRO) plays a central role in governing the behavior of multi‐principal element alloys. This perspective critically assesses computational and experimental approaches for quantifying, characterizing, and validating CSRO, emphasizing modeling–experiment cross‐validation pathways that enable more reliable interpretation of ...

The SPARK That Ignited a New Era of Research [PDF]

Circulation, 2002
In the spring of 1998, as members of both the House and Senate were signaling their interest in increasing National Institutes of Health (NIH) appropriations substantially over the next several years, the National Heart, Lung, and Blood Institute (NHLBI) convened the “SPARK Working Group, ” a panel of prominent scientists, to identify extraordinary ...
