Tomato plants control leaf sodium levels to limit damage by Spodoptera littoralis larvae

New Phytologist, Volume 250, Issue 5, Page 3417-3427, June 2026.
Summary Sodium is an essential element for animal growth and survival. Here we test the hypothesis that plants exposed to insect feeding can translocate sodium from the feeding site to other plant organs as a defense strategy against phytophagous insects, which need sodium in their diet.

Contaminants of emerging concern in agricultural soils: Current understanding, overlooked issues, and future priorities

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 792-810, May 2026.
Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found

Reduced snow cover at the alpine treeline: resistance and recovery of saplings

New Phytologist, Volume 250, Issue 3, Page 1492-1509, May 2026.
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

El sentido de ser en las entidades virtuales

Revista Filosofía UIS
el presente escrito intenta poner sobre la mesa la pregunta por el sentido de ser de las entidades virtuales. Para ello, se muestra en un primer momento el sentido de ser que ha dominado en la tradición occidental: el ser como sustancialidad.

Novel roles of sulfur metabolism in stress‐controlled stomata aperture regulation

New Phytologist, Volume 250, Issue 3, Page 1460-1467, May 2026.
Summary Stomatal closure allows plants to conserve water by reducing transpiration during drought. Surprisingly, the assimilation of the macronutrient sulfur is intimately connected to the drought stress response. This Tansley insight will only briefly touch on the general impact of sulfate assimilation on the production of drought‐response metabolites.

El holismo cosmoteándrico de Raimon Panikkar y el holismo sustancial de Fernando Inciarte: ¿dos metafísicas de sistema?

Areté, 2020
Este artículo se dirige a contrastar las metafísicas de Raimon Panikkar y Fernando Inciarte. Al examinar, en las dos primeras partes, sus formas de contestar a la pregunta metafísica fundamental por lo que es, encontramos las respuestas aparentemente ...

A chromosome‐scale genome assembly of Hordeum erectifolium: genomic, transcriptomic and anatomical adaptations to drought in a wild barley relative

New Phytologist, Volume 250, Issue 4, Page 2652-2669, May 2026.
Summary Wild crop relatives are valuable genetic resources for improving stress adaptation in cultivated species, but their effective use depends on high‐quality reference genomes integrated with phenotypic and molecular datasets. Hordeum erectifolium, a wild relative of barley (H.

Multi‐Metallic Organic Framework‐Based Composites as Electrocatalysts

Small, Volume 22, Issue 19, 1 April 2026.
Multi‐metallic organic framework (MMOF) composites and their derivatives offer a versatile platform for electrocatalysis by coupling abundant active sites with improved conductivity and stability. This review summarizes recent advances in MMOF‐based heterostructures with metal, carbon, and multi‐partner components, highlighting synergistic interactions
