Question the Mark: A Review and Assessment of Bat Marking Practices
Mammal Review, Volume 56, Issue 1, March 2026.We reviewed a decade of research on bats and conducted a broader systematic review to assess the nature of bat marking practices and the effects and efficacy of marks. Effects of marks on bats, mark details and marking procedures are rarely reported and further research on the effects of marks on bats and more thorough reporting are needed.

From Light‐Driven to Dark Synthesis: Streamlining Perfluoroalkyl Selenide Ether Formation
European Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.Two orthogonal and user‐friendly protocols enable the efficient construction of (Se/S)RF bonds from simple dichalcogenides and perfluoroalkyl iodides. Visible‐light irradiation at 395 nm promotes seleno‐ and thioether formation, while a dark KOH/MeCN variant delivers selenoethers in minutes. Both approaches operate under mild, metal‐ and photocatalyst‐

Vertical Self‐Rectifying Memristive Arrays for Page‐Wise Parallel Logic and Arithmetic Processing
Advanced Materials, Volume 38, Issue 8, 6 February 2026.This study proposes a page‐wise logic‐in‐memory architecture realized in a 3D vertical resistvie random‐access memory array of self‐rectifying memristors. By introducing intra‐ and inter‐page logic primitives, the system enables Boolean and arithmetic operations to be executed directly within the memory.
