Leaf size in mosses is structurally constrained by cell dimensions and genome size

open access: yesPlant Biology, Volume 28, Issue 2, Page 420-431, March 2026.
Cell size and midribs are the main mechanical determinants of moss leaf size, which itself depends on growth form and genome size; together, these relationships underpin key aspects of moss ecology and performance. Abstract Leaf anatomy is a key factor determining plant ecology.

Hyper‐Reduced Model Based on the Proper Orthogonal Decomposition and the LU Factorization Applied to the Neutron Diffusion Eigenvalue Problem

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.
ABSTRACT An efficient method for solving large eigenvalue problems efficiently can be developed using hyper‐reduced order models, such as those arising from the LU Proper Orthogonal Decomposition (LUPOD). The LUPOD employs dominant orthogonal modes along with a flexible number of collocation points to establish a reduced scalar product, thereby ...

Construction of Phospholipid‐Like Vesicles by Aqueous Aminolysis of Acyl Thioesters With Diamino Acids

open access: yesChemistry – A European Journal, Volume 32, Issue 6, 9 February 2026.
Membrane‐forming phospholipids are produced in cells via enzymatic diacylation. Here, we show that direct aminolysis of acyl thioesters with diamino acids in aqueous environments enables the synthesis of diacylated amino acids (DAAAs), which spontaneously self‐assemble into robust phospholipid‐like vesicles across a broad range of pH and temperature ...

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

Televisión con cultura / cultura con televisión

open access: yesPalabra Clave, 2004
Es evidente la necesidad de valorar los programas con intencionalidad cultural, especialmente en la televisión pública, atendiendo a los objetivos que se proponen en su estructura y en las consecuencias no previstas que se derivan de su aplicación. De igual modo, los resultados de dichas investigaciones deben ser considerados por los responsables de la
