Mycorrhizal fungi form hyphal networks for water and solute transport between soil and plant roots. Trait-based research on these organisms typically focuses on spores and resource exchange structures within plant roots, but researchers have explored extraradical networks, the larger part of these organisms, much less. To stimulate more research in this area, I review the literature on mycorrhizal networks, viewing them as biological vascular systems of pipelines that grow dynamically for resource exploration. In this context, I explore how fluid mechanics can offer traits that are valid in understanding eco-evolutionary trade-offs. I also consider the associated topological traits that affect solute transport within hyphal networks. In addition, I identify knowledge gaps and review methodologies for future research in this space.

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent hyperglycemia with multiple clinical manifestations and complications, such as cardiovascular disease, kidney dysfunction, retinal impairment, and peripheral neuropathy. Continuous and minimally invasive glucose monitoring is essential for effective DM management. Microneedles (MNs)-based sensing platforms offer a promising solution; however, conventional polymeric MNs suffer from limited electrochemical sensitivity due to their insufficient electroactive surface area and inefficient loading of catalytic and enzymatic components.

Multicellular organisms generate organizational complexity through morphogenesis, in which mechanical forces orchestrate the movements and deformations of cells and tissues, while chemical signals regulate the molecular events that generate and coordinate these forces. One common denominator that is critical both for mechanics and biochemistry is material property. Material properties define how materials deform or rearrange under applied forces, and how rapidly molecules interact or spread in space and time.

Purpose: The design and development of ventricular assist devices have heavily relied on computational tools, particularly computational fluid dynamics (CFD), since the early 2000s. However, traditional CFD-based optimization requires costly trial-and-error approaches involving multiple design cycles. This study aims to propose a more efficient VAD design and optimization framework that overcomes these limitations.

Microgravity experiments on board the International Space Station, combined with particle-resolved direct numerical simulations, were conducted to investigate the long-term flocculation behavior of clay suspensions in saline water in the absence of gravity. After an initial homogenization of the suspensions, different clay compositions were continuously monitored for 99 days, allowing a detailed analysis of aggregate growth through image processing. The results indicate that the onboard oscillations (g-jitter) may have accelerated the aggregation process.

Colposcopy is an important method for early clinical cervical cancer screening, but the traditional vaginal dilator has problems such as discomfort in use and cumbersome operation. For this reason, this study aims to design an intelligent vaginal dilatation system to automate colposcopy and enhance patient comfort.
