Rational points on even‐dimensional Fermat cubics

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Meroterpenoids Produced by Fungi: Occurrence, Structural Diversity, and Biological Activity (An Update: February 2020 to December 2025)

open access: yesChemistry &Biodiversity, Volume 23, Issue 11, November 2026.
This review firstly summarizes the update of meroterpenoids from February 2020 to December 2025 by applying a new classification method based on twelve key non‐terpene precursors. ABSTRACT Meroterpenoids are a class of hybrid natural products, biosynthesized from terpenoid fragments and non‐terpenoid precursors, exhibiting a wide range of biological ...

Dichloroacetate Improves Animal Survival, Growth, Neuromuscular Activity, Mitochondrial Stress and Physiology, and Elevated Lactate in C. elegans pdha‐1 and dld‐1 RNAi Models of Pyruvate Dehydrogenase Complex Deficiency (PDCD)

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 6, November 2026.
ABSTRACT Pyruvate dehydrogenase complex (PDHc) deficiency (PDCD) is a primary mitochondrial disorder characterized by neurodevelopmental disability, altered intermediary metabolism, and early mortality. Dichloroacetate (DCA), a pyruvate analog, activates PDHc and remains under clinical investigation for treatment of PDCD.

Peskine Sixfolds and Debarre–Voisin Fourfolds With Associated Cubic Fourfolds

open access: yesMathematische Nachrichten, Volume 299, Issue 11, Page 3367-3391, November 2026.
ABSTRACT We develop the notion of Peskine sixfolds with associated K3 surfaces and cubic fourfolds and work out numerical conditions for when these associations occur. In discriminant 24, the first family for which there is an associated cubic fourfold, we identify the cubic explicitly.

Does the Adoption of Improved Cassava Varieties Boost Productivity in Ghana? The Role of Technology, Management, and Structural Gaps

open access: yesWorld Food Policy, Volume 12, Issue 2, November 2026.
ABSTRACT Agricultural development initiatives in sub‐Saharan Africa have emphasized improved crop varieties as a pathway to food security, resilience, and rural poverty reduction. However, empirical evidence often focuses narrowly on plot‐level outcomes and overlooks whole‐farm effects and the substantial heterogeneity in farmers' management practices,
