Cattle foraging on milkweed: Intra‐seasonal herbivory shifts and implications for monarch butterfly conservation

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Managing milkweed (Asclepias spp.) is of high conservation concern due to its association with monarch butterflies (Danaus plexippus L.), which are proposed for listing under the Endangered Species Act. To counteract monarch declines, conservation goals aim to establish ≥1.6 billion nonagricultural milkweed stems within the Midwestern United ...

Redox Regulation and Oxidative Stress in Health and Disease: Mechanisms and Therapeutic Targeting

open access: yesMedComm – Future Medicine, Volume 5, Issue 2, June 2026.
Reactive species serve crucial roles which are tightly regulated in both physiological as well as disease states. At physiological levels, these species are integral to redox signaling, while uncontrolled redox promotes disease pathology. This review examines the dysregulation of these processes.

Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications

open access: yesPackaging Technology and Science, Volume 39, Issue 6, Page 685-695, June 2026.
Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and
