A Diagnostic and Performance System for Soccer: Technical Design and Development.
Sports (Basel)
January 2025
Aragon Institute of Engineering Research, University of Zaragoza, 50018 Zaragoza, Spain.
This study presents a novel system for diagnosing and evaluating soccer performance using wearable inertial sensors integrated into players' insoles. Designed to meet the needs of professional podiatrists and sports practitioners, the system focuses on three key soccer-related movements: passing, shooting, and changes of direction (CoDs). The system leverages low-power IMU sensors, Bluetooth Low Energy (BLE) communication, and a cloud-based architecture to enable real-time data analysis and performance feedback.

Manipulating flexible and underactuated objects, such as a whip, remains a significant challenge in robotics. Remarkably, humans can skillfully manipulate such objects to achieve tasks, ranging from hitting distant targets to extinguishing a cigarette's in someone's mouth with the tip of a whip. This study explored this problem by constructing and modeling a 25-degree-of-freedom whip.

Neural diversity can expand the encoding capacity of a circuitry. A striking example of diverse structure and function is presented by the afferent synapses between inner hair cells (IHCs) and spiral ganglion neurons (SGNs) in the cochlea. Presynaptic active zones at the pillar IHC side activate at lower IHC potentials than those of the modiolar side that have more presynaptic Ca channels.

Stargardt disease (STGD), the leading cause of inherited childhood blindness, is primarily caused by mutations in the ABCA4 gene; yet, the underlying mechanisms of photoreceptor degeneration remain elusive, partly due to limitations in existing animal disease models. To expand our understanding, we mutated the human ABCA4 paralogues abca4a and abca4b in zebrafish, which has a cone-rich retina. Our study unveiled striking dysmorphology and elongation of cone outer segments (COS) in abca4a;abca4b double mutants, alongside reduced phagocytosis by the retinal pigmented epithelium (RPE).

Article Synopsis
- Researchers studied how gametes (reproductive cells) develop in clusters called cysts, which are formed from germ cells connected by intercellular bridges that allow them to share materials.
- They used advanced live imaging techniques to observe the movement and behavior of these germ cells in their natural environment, revealing how their motility contributes to the formation and breaking of these cysts during embryonic development.
- The study suggests a balance between cell movement and the stability of intercellular connections determines the size of cysts, with implications for understanding how oocytes (egg cells) are selected and the overall female reproductive system development.
