On the conflict between science and ethics: the case of the moggel, Labeo umbratus (Teleostei: Cyprinidae) from South Africa

open access: yesJournal of Fish Biology, Volume 108, Issue 2, Page 596-608, February 2026.
Abstract Recent molecular evidence showed that Labeo umbratus comprises two allopatrically distributed genetic lineages, a northern lineage confined to the Orange‐Vaal River system where this species was originally described and a southern lineage with three geographically separated haplogroups (western, central and eastern) distributed across multiple

Design and Analysis of a 6‐Speed Coaxial Magnetic Gearbox With Axial Gear Shifting Mechanism for Automotive Applications

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes a multi‐stage magnetic gearbox (MSMG) designed for automotive applications. The proposed architecture provides six distinct gear ratios within an integrated system. By effectively suppressing eddy current losses through adaptive segmentation, this design ensures robust performance for high‐power propulsion systems.

Factory Performance Testing of RV Reducer Based on Wireless Vibration Sensing Technology

open access: yesShock and Vibration, Volume 2026, Issue 1, 2026.
In the factory inspection of RV reducers, traditional wired sensors face issues such as limited wiring, signal attenuation, and the lack of quantitative standards for manual judgment, which can easily lead to detection errors. This paper develops a wireless vibration acceleration sensor that can be directly magnetically attached to the output shaft end
