Hybrid kernels integrating genomic and multispectral data improve wheat genomic prediction accuracy

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Genomic selection (GS) is transforming plant breeding by enabling more accurate and efficient identification of superior genotypes. However, its practical implementation remains challenging, as achieving high prediction accuracy is critical for its success. Several factors—including sample size, the degree of relatedness among individuals, and

Along the Silenced Footsteps of Latin American Pastoralists: From Mexico to Argentina, a Journey Through Pastoral Systems in Latin America

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 1, March 2026.
ABSTRACT Pastoralism worldwide faces a complex landscape of increased pressures and exclusion. Beyond ecological and economic challenges, pastoralists suffer eroding cultural identity, limited generational renewal, and political marginalization. Yet pastoral livelihoods are increasingly recognized as stewards of sustainable futures and amongst the best

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework

open access: yesAmerican Journal of Human Biology, Volume 38, Issue 2, February 2026.
ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to

Ginsenoside Rg1 as a Multifunctional Therapeutic Agent: Pharmacological Properties, Molecular Mechanisms and Clinical Perspectives in Complementary Medicine

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
Ginsenoside Rg1 (Rg1) from Panax ginseng shows multifunctional health effects. Although oral bioavailability is low and blood–brain barrier (BBB) penetration is limited, delivery systems such as liposomes and nanoparticles may improve exposure. Rg1 reduces inflammation/oxidative stress by inhibiting nuclear factor‐κB (NF‐κB) signaling and reactive ...

Management Strategies and Agricultural Calendars for Forage Production in Semi‐Arid Brazil Using AquaCrop

open access: yesIrrigation and Drainage, Volume 75, Issue 1, Page 411-424, February 2026.
ABSTRACT Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles ...
