The Optimal Quantity of Land in Agriculture [PDF]
Northeastern Journal of Agricultural and Resource Economics, 1989 In 1952, when T. W. Schultz declared that land had lost its place as a unique factor of production, he was certainly right about U.S. agriculture. For the almost four decades since Schultz's prophetic analysis, output of U.S. agriculture has increased steadily while the exploited land base has slightly decreased.

Achieving High‐Density and Stress‐Resilient Maize Breeding Via Germplasm Innovation
Advanced Science, EarlyView.Global population growth and climate change have exacerbated the global food crisis. This perspective presents a conceptual framework focusing on enhancing population advantages. Several novel breeding objectives are proposed to improve density tolerance and stress resistance for yield improvement.

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits
Advanced Science, EarlyView.Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Biosynthesis of Sciadonic Acid Derived from Gymnosperms with Anti‐Colitis Activity
Advanced Science, EarlyView.This study establishes an efficient Yarrowia lipolytica platform for unusual sciadonic acid (SCA) production and assess the anti‐colitis efficacy in mice of SCA, supporting its potential as a novel therapeutic lipid. ABSTRACT Sciadonic acid (SCA), Δ5‐unsaturated fatty acid with anti‐inflammatory and lipid‐regulatory properties, is predominantly derived
