Comparative Efficiency of eDNA, Camera Traps and Scat Surveys to Detect a Semi‐Aquatic Mammal Across Multiple Catchments

Animal Conservation, EarlyView.
Monitoring semi‐aquatic mammals is essential for their conservation, but it is made difficult by their elusive lifestyle and generally low abundance. Eurasian otter (Lutra lutra) monitoring has traditionally relied on scat surveys, but eDNA and camera‐trapping are emerging as promising alternatives.

Bioresorbable Scaffolds for Coronary Arteries: Where Do We Stand Today?

VIEW Medicine, Volume 1, Issue 1, August 2026.
Bioresorbable coronary scaffolds are moving from thick strut pitfalls to thinner, stronger, healing‐oriented designs. Integrating advances in materials, guided implantation with preparation, size, and postdilation steps, and resorption aligned to healing, we synthesize clinical evidence and chart a roadmap toward intelligent, transient platforms ...

A Printed Wide‐Slot Antenna With Modified Tuning Stub and Parasitic Elements for Glucose Sensing Applications

Engineering Reports, Volume 8, Issue 7, July 2026.
A compact printed wide‐slot antenna with a diamond‐shaped tuning stub and parasitic elements achieves an ultrawide impedance bandwidth of 256% (2.4–16.2 GHz). Its capacitive nature enables frequency shifts with dielectric variations, making it highly suitable for accurate, non‐invasive glucose sensing applications.
