Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

DAMP Laden Extracellular Vesicles From the Airways of Patients With Severe SARS‐CoV‐2 Respiratory Infection Compromise Inflammation and Cellular Metabolism

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
Extracellular vesicles from severe COVID‐19 airways carry depleted miRNAs and elevated DAMPs, reprogramming monocytes toward senescence, impaired metabolism, and predominantly reduced cytokine responses. However, they drive excess IL‐8 production, amplifying neutrophil recruitment and dysfunctional inflammation across the respiratory tract.

The Role of Magnetic Resonance Spectroscopy (MRS), Diffusion‐Tensor‐Imaging (DTI) and Structural MRI in the Alzheimer's Disease and Mild Cognitive Impairment Diagnosis: A Review

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 6, Page 1509-1545, June 2026.
ABSTRACT Alzheimer's disease (AD) is one of the most common neurological disorders affecting older adults, with approximately 7.2 million cases only in the United States. This number is projected to increase to 13.8 million in the United States by 2060, leading to increased expenditures for healthcare, long‐term care and hospice services. Consequently,
