This study investigated the mechanism of Wuda granule (WDG) on gastrointestinal (GI) motility in beagle dogs. Stress sensors implanted in the stomach, duodenum, jejunum, and colon recorded contractile activity. Lateral ventricular administration of WDG (5mg) significantly enhanced contractile motility in all recorded GI regions in awake dogs; this effect was attenuated under intravenous anesthesia. The prokinetic effect of central WDG was completely blocked by intravenous atropine infusion [50 μg/(kg·h)]. Bilateral cervical vagotomy prolonged the migrating motor complex cycle, weakened gastric phase III contractions, and abolished the WDG-induced enhancement specifically in the stomach. However, WDG still enhanced motility in the duodenum, jejunum, and colon post-vagotomy. Transmission electron microscopy confirmed no intestinal structural changes induced by WDG. WDG enhances GI contractility centrally, primarily via activation of vagal cholinergic pathways for the stomach, while exerting effects on the lower GI tract through additional, non-vagal mechanisms.

Carrot color is influenced by its carotenoid content, and understanding the genetic mechanisms behind this trait is crucial for breeding more nutritious carrots. 

A research paper by scientists at Shanghai Jiao Tong University School of Medicine presented BioCompNet—an end-to-end deep learning workflow that integrates dual-parametric magnetic resonance imaging (MRI) sequences (water/fat) with a hierarchical U-Net architecture to enable fully automated quantification of 15 biomechanically critical BC components..

A joint research team from the Institute of Geochemistry of the Chinese Academy of Sciences (IGCAS) and Shandong University has for the first time identified crystalline hematite (α-Fe₂O₃) and maghemite (γ-Fe₂O₃) formed by a major impact event in lunar soil samples retrieved by China's Chang'e-6 mission from the South Pole–Aitken (SPA) Basin. 

A recent study investigates the role of sonic vibrations in improving pollination efficiency and fruit size in tomatoes. 

Tea bud size is closely tied to both yield and processing suitability in tea production. 

In bustling megacities worldwide, smart trains and railways are emerging as heroes in the fight against gridlocked traffic and choking pollution. Powered by cutting-edge tech like IoT and digital connectivity, these systems promise faster, greener, and more personalized travel—think seamless real-time updates and automated operations. Yet, this digital evolution brings a dark side: heightened vulnerability to cyberattacks that could derail operations, compromise passenger safety, or expose sensitive data. As railways go "smart," the need for robust cybersecurity isn't just a tech add-on—it's essential to unlock the full potential of a connected world without inviting chaos. This study dives into the cybersecurity maze of smart railways, mapping out threats, vulnerabilities, and defenses to ensure these vital infrastructures remain resilient in an increasingly hostile digital landscape.

Space manipulators play an important role in the on-orbit services and planetary surface operation whose reliability is a key issue. In the extreme environment of space, space manipulators are susceptible to a variety of unknown disturbances. Since it is difficult for the manipulator to be repaired immediately, once it fails, it will mean that it cannot complete the mission as expected, which may cause serious losses and dangers. How to have a resilient guarantee, i.e., the manipulator’s ability to resiliently recover and continue to complete tasks, in failure or disturbance is the core capability of its future development. The motion planning unit is used as the computing terminal of the manipulator’s joint motion trajectory. Compared with traditional motion planning, learning-based motion planning has gradually become a hot spot in current research. However, no matter what kind of research ideas, the single robotic manipulator is studied as an independent agent, making it unable to provide sufficient flexibility under conditions such as external force disturbance, observation noise, and mechanical failure.
