Tau Phosphorylation as an Adaptive Physiological Response: Implications for the Therapy of Tauopathies

The FASEB Journal, Volume 40, Issue 4, 28 February 2026.
Drawing on recent studies suggesting that tau phosphorylation is reversible, therapies for tauopathies could enhance reversibility, for example, by dismantling aggregated tau species. ABSTRACT Recent evidence demonstrates that tau phosphorylation, traditionally viewed as a hallmark of neurodegeneration, also occurs in completely reversible ...

On the Role of Western Boundary Currents to Fertilize Adjacent Continental Shelves at Interannual Scales: A Case Study in the Southwestern Atlantic

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Exchanges between continental shelves and open ocean basins regulate the transport of heat, salt, and nutrients. In the Southwestern Atlantic, the western boundary current known as the Malvinas Current (MC) fertilizes the outer shelf through recurrent slope‐water intrusions.

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‐

An In Situ Study of the Topochemical Transformation of Hybrid Layered Hydroxides Into Metallic Nanocomposites

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
Herein, the topochemical transformation of cobalt‐based layered hydroxides into nanocomposites is investigated using advanced real‐time characterization techniques combined with thermogravimetric analysis. The study reveals how interlayer carboxylic acids direct the transformation pathway, highlighting the role of carbon content and anion length. These

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.
