Experimental Evaluation of Turning AISI 304 Using Minimum Quantity Lubrication With Vegetable‐Based Green Cutting Fluids

MetalMat, Volume 3, Issue 1, March 2026.
This study experimentally evaluates the performance of eco‐friendly vegetable‐based cutting fluids—coconut, sunflower, and palm oils—during turning of AISI 304 stainless steel under minimum quantity lubrication. Palm oil exhibited superior lubrication and cooling characteristics, yielding the lowest cutting force, temperature, and surface roughness ...

Gene Editing of a Susceptibility LncRNA Enhances Broad‐Spectrum Disease Resistance in Rice without Developmental Trade‐Offs

Advanced Science, Volume 12, Issue 47, December 18, 2025.
Editing susceptibility lncRNAs offers a strategy to enhance disease resistance without yield loss. RESIS, a domestication‐acquired, pathogen‐induced lncRNA, promotes protein N‐terminal acetylation through its interaction with NatA complex. Knockout of RESIS increases translation and confers broad‐spectrum resistance to both fungal and bacterial ...
