open access: yes
Rainfall was collected on the University of Central Florida (UCF) campus near Orlando since July 1977 and at the Kennedy Space Center (KSC), Florida since August 1977.

Rieske Iron–Sulfur Cluster Proteins From an Anaerobic Ammonium Oxidizer Suggest Unusual Energetics in Their Parent Rieske/Cytochrome b Complexes

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 4, Page 905-920, April 2026.
ABSTRACT Anaerobic ammonium‐oxidizing (anammox) bacteria employ a unique, hydrazine‐based pathway to obtain energy from nitrite and ammonium. These organisms possess distinct Rieske/cytochrome b complexes whose precise role in anammox metabolism remains unclear, but which have been proposed to include the generation of NAD(P)H.

Genomic and Transcriptomic Insights Into the Autotrophic Metabolism on H2 + CO2 or CO of the Thermophilic Acetogenic Model Organism Moorella thermoacetica

open access: yesEnvironmental Microbiology, Volume 28, Issue 4, April 2026.
Moorella thermoacetica is the model organism for elucidation of acetogenesis. The reduction of CO2 to acetate is well studied, but how redox carrier balancing and energy conservation are maintained during autotrophic growth and how H2 is oxidised remains enigmatic.

Gut Luminal Exosomes in Young and Old Mice: Multi‐Omic Characteristics and Regulation of Gut Permeability

open access: yesAging Cell, Volume 25, Issue 4, April 2026.
This graphical abstract shows that gut luminal exosomes (LFEs) change with aging, with old mice producing LFEs that disrupt gut barrier integrity, alter microbiome composition, and promote insulin resistance. In contrast, LFEs from young mice improve gut barrier function and metabolic health, and transferring these LFEs can partially reverse age ...

Photochemical N‐dealkylation of Tertiary Amines Coupled With Photocharging of Poly(Heptazine Imides)

open access: yesAngewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Protonated poly(heptazine imide) (H‐PHI) functions as an energy reservoir, thereby facilitating the endothermic dealkylation of triethylamine through a proton‐coupled two‐electron transfer (PC2ET) process. The extent of photocharging is quantitatively described by a molecular‐level descriptor, Ne:Nhept, providing a direct correlation between stored ...

The return of metabolism: biochemistry and physiology of glycolysis

open access: yesBiological Reviews, Volume 101, Issue 2, Page 751-803, April 2026.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Fruit respiration: putting alternative pathways into perspective

open access: yesNew Phytologist, Volume 250, Issue 1, Page 54-73, April 2026.
Summary Over the past century, research has significantly advanced our understanding of fruit respiration, from (eco)physiological processes to molecular mechanisms. This review focuses on the functional relevance and regulatory roles of mitochondrial alternative respiratory pathways (ARPs) during fruit growth and ripening.
