Space Pump: Repairable 3D‐Printed Bioinspired Pneumatic Peristaltic Pump for Fluid and Regolith Transport in Space

Advanced Intelligent Systems, EarlyView.
The space pump transports lunar regolith under vacuum condition. A fully 3D‐printed biomimetic peristaltic pump demonstrates reliable transport of liquids and solids using pneumatic ring actuators and flexible fused filament fabrication. The system operates under atmospheric and vacuum conditions, achieves high flow rates, and enables self‐priming ...

Bacillus thuringiensis Conjugation in Simulated Microgravity

Astrobiology, 2009
Spaceflight experiments have suggested a possible effect of microgravity on the plasmid transfer among strains of the Gram-positive Bacillus thuringiensis, as opposed to no effect recorded for Gram-negative conjugation. To investigate these potential effects in a more affordable experimental setup, three ground-based microgravity simulators were tested:

Electrospun Porous Materials for the Next‐Generation Proton Exchange Membrane Fuel Cells: Progress, Challenges, and AI‐Optimized Perspectives

Carbon Energy, EarlyView.
Incorporating AI to optimize solution, process, and environment enables efficient prediction of structural properties and performance, allowing tailoring of GDL, CL, and PEM fabrication to guide PEMFC toward 9.0 kW L‒1 by 2040. ABSTRACT The performance and commercial viability of proton exchange membrane fuel cells (PEMFCs) are constrained by key ...

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...
