White matter hyperintensities are associated with locus coeruleus atrophy and astrocytic β2‐adrenergic receptor expression

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION White matter hyperintensities (WMHs) are a robust marker of brain aging and dementia risk, typically attributed to vascular pathology. However, impaired astrocytic support may also contribute. The locus coeruleus (LC), which degenerates early in aging and Alzheimer's disease, provides widespread noradrenergic projections that ...

The Decline of a Caldera‐Filling Glacier at Volcán Sollipulli, Chile

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Southern Andean glaciers have undergone fast retreat in recent decades. This results in reduced freshwater storage, contribution to sea‐level rise, and locally to the formation of glacial lakes, that may pose the risk of glacial lake outburst floods (GLOFs).

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

Insect Science, Volume 33, Issue 3, Page 1097-1108, June 2026.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be
