Navigating the Ethereal Tightrope: The Nanogenerator Manipulates Neurons for Immune Equilibrium. [PDF]

open access: yesAdv Sci (Weinh)
This review explores how nanogenerators modulate neuroimmune responses, offering innovative strategies for treating neurological disorders. By interfacing with neural pathways, they enable precise control of immune activity, especially via vagus nerve stimulation.

Personalized Models of Biological Barriers and Their Diseases: Recent Progress with Organs‐On‐Chips

open access: yesAdvanced Biology, Volume 10, Issue 2, February 2026.
Buck and Bugter et al. explore the architectural diversity and physiological functions of human barrier systems and reveal how organ‐on‐chip platforms, particularly those integrating patient‐derived cells, are advancing barrier disease modeling. They highlight how emerging biological and technological advances can be used to bridge the gap between ...

A Hydrodynamic Bioreactor for High‐Yield Production of Extracellular Vesicles from Stem Cell Spheroids with Defined Cargo Profiling

open access: yesAdvanced Science, Volume 13, Issue 10, 18 February 2026.
This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...

Autonomous Implants

open access: yesAdvanced Materials, Volume 37, Issue 45, November 13, 2025.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Suitport extra-vehicular access facility [PDF]

open access: yes, 1989
In a system for entering and leaving a space station, a bulkhead divides the module into an antechamber and an airlock. A space suit has a portable life support system (PLSS) interface on its back.
