From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Israel's Post‐War Healthcare Obligations

Bioethics, Volume 40, Issue 8, Page 828-832, October 2026.
ABSTRACT Since the beginning of the Israel–Hamas war in 2023, the healthcare infrastructure within Gaza has been dismantled. While international humanitarian law mandates distinction between lawful targets (combatants and military objectives) and non‐lawful targets (civilians and civilian objects), and acknowledging the inherent complexities of ...

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics
