Using FoxP2 to Distinguish Direct and Indirect Basal Ganglia Pathways for Vocal Learning in Songbirds

Developmental Neurobiology, Volume 86, Issue 2, April 2026.
ABSTRACT The cortico‐basal ganglia pathways that mediate vocal learning in zebra finches (Taeniopygia guttata) are localized in parallel circuits formed by CORE and SHELL subregions. These circuits traverse a specialized region of the basal ganglia essential for vocal learning (Area X), which includes intermixed striatal and pallidal neurons.

Programmable Antigen‐Specific Immunity via Self‐Adjuvanting Nanovaccines Co‐Delivering Immune Modulators

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
The self‐adjuvanting vaccine—comprising a covalent conjugate of antigen and adjuvant—was formulated into cationic lipid nanoparticles smaller than 100 nm to facilitate uptake by immune cells, with supplemental adjuvants incorporated to modulate immune responses.

A Review on Cracking in Laser Additive Manufacturing of Nickel‐Based Superalloys: Types, Formation Mechanisms, and Suppression Strategies

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Unequal Land and Water Changes Between Nations Driven by International Boundary Rivers: Mapping and Temporal Analysis of Shared Borders Between China and Its Neighbors

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract International Boundary Rivers (IBRs), as natural political frontiers, constitute one‐third of China's land borders. However, a lack of systematic monitoring has led to a limited understanding of the distribution of these politically significant rivers and the potential risks posed by their dynamic nature.
