Biomechanical Trade‐Offs Between Root Tensile Strength and Porosity in Coastal Marshes

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Root biomechanics play a fundamental role in stabilizing wetland soils and sustaining coastal ecosystems under increasing environmental stress. This study investigates the tensile strength (TS) and internal porosity (n) of roots from two dominant marsh grasses, Spartina alterniflora and Spartina patens, across four sites in the Mississippi ...

Dietary Protein Restriction Ameliorates Cardiac Inflammaging via AMPK‐ULK1‐Mediated Mitochondrial Quality Control

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Dietary protein restriction protects the aging heart in the context of obesity by limiting mitochondrial DNA leakage and suppressing cGAS–STING‐driven inflammation. Through AMPK–ULK1‐dependent mitophagy, protein restriction restores mitochondrial quality control, reduces cardiac remodeling, and preserves metabolic homeostasis during obesity‐associated ...

Effects of Phytoplasma Infection on Aster Leafhopper (Macrosteles quadrilineatus) Settling Behavior and Development on Brassica napus

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 2, Page 132-141, February 2026.
Aster yellows phytoplasma (AYp) infection alters host plant preference in aster leafhoppers (Macrosteles quadrilineatus), with infected vectors showing a significant preference for AYp‐infected canola (Brassica napus) early in the infection period. However, this preference fades as infection progresses. Despite early attraction, B.

Household Food Insecurity Is Associated With Higher Adiposity Over Time Among Adolescents in Louisiana

open access: yesPediatric Obesity, Volume 21, Issue 2, February 2026.
ABSTRACT Background Few studies have examined how household food insecurity may impact longitudinal changes in adiposity among adolescents. Objective We investigated the link between household food insecurity and 2‐year change in adolescent adiposity, with sex as a potential moderator.

Characterizing Martian Primary Crustal Compositions With Gamma Ray Spectroscopy

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Mars's global‐scale chemical maps of the midlatitudes, derived from Mars Odyssey gamma and neutron spectroscopy, have constrained martian geology across a multitude of processes. However, the chemical maps are often used to analyze pre‐defined regions based on mapped geology and/or mineralogy.

Spatial neophobia is still not correlated with object neophobia in wild-caught house sparrows (Passer domesticus)

open access: yesRoyal Society Open Science
Neophobia, aversive behaviour towards novel objects, foods and environments, is a trait that affects the ability of animals to adapt to new environments and exploit novel resources.

Comments on Caddo Origins in Northwest Louisiana [PDF]

open access: yes, 2009
This paper presents some of my thoughts on the issue of Caddo origins from the perspective of the Red River drainage in northwest Louisiana. These ideas were assembled prior to the Caddo discussion group meeting held in December 2008 and have been only ...

Proximity to Industrial Releases of Toxins and Childhood Respiratory, Developmental, and Neurological Diseases: Environmental Ascription in East Baton Rouge Parish [PDF]

open access: yes
Recent research by Legot et al. (2010a, 2010b) has identified East Baton Rouge Parish (EBR) as a locus of particularly high volumes of emissions of developmental neurotoxins, i.e., those toxins that put children’s health and, especially, learning ...
