Discordance of Dopaminergic Dysfunction and Subcortical Atrophy by α‐Synuclein Status in Sporadic and Genetic Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is characterized by predominantly neuronal α‐synuclein pathology and dopaminergic dysfunction. Cerebrospinal fluid (CSF) seeding amplification assays (SAA) detect α‐synuclein aggregates in vivo, but not all patients with PD have a positive SAA.

Combining social, ecological and economic approaches in knowledge co‐production enables the identification of sustainable farming options

open access: yesPeople and Nature, EarlyView.
Abstract Farming systems face an increasing sustainability challenge requiring integrated solutions to minimize the trade‐offs between the social, ecological and economic dimensions of sustainability. Yet, most research remains siloed, limiting interdisciplinary understanding of farming systems as coupled social‐ecological systems (SESs) and precluding

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Evaluation of a High‐Performance Monopropellant Formed of Microencapsulated Hydrocarbon Fuels in Combination With Gelled Hydrogen Peroxide in a Strand Burner Setup

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
A high‐performance premixed monopropellant is prepared from hydrocarbon‐filled microcapsules and hydrogen peroxide. This propellant is burned in a strand burner, and the effect of different parameters on the burn rate is evaluated. ABSTRACT A dispersion of hydrocarbon‐fuel‐filled microcapsules in gelled hydrogen peroxide can form a premixed ...

Picky Eaters: Carbon Isotopic Evidence for the Uniform Bioavailability of Riverine Dissolved Organic Matter to a Model Marine Microorganism

open access: yesGeophysical Research Letters
Dissolved organic matter (DOM) is a key component of the global carbon cycle, with rivers delivering significant amounts of DOM to oceans. Urbanization and agricultural land‐use alter the age and chemical composition of riverine DOM, which likely impact ...

Structure and Mechanism of PhdC, a Prenylated‐Flavin Maturase

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Prenylated flavin mononucleotide (prFMN) is a modified flavin cofactor required by the UbiD family of (de)carboxylase enzymes. While the reduced prFMNH2 form is produced by the flavin prenyltransferase UbiX, the corresponding two‐electron oxidized prFMNiminium form is required to support UbiD catalysis. Thus, oxidative maturation of prFMNH2 is

Construction of an O2‐responsive engineering bioreactor for enhanced indole‐3‐propionic acid production and deoxynivalenol detoxification

open access: yesResponsive Materials, EarlyView.
An oxygen‐responsive living bioreactor was engineered via interspecies protoplast fusion, converting oxygen from an inhibitory stress into a programmable signal for sustained indole‐3‐propionic acid (IPA) production. This genetically encoded bioreactor enables robust aerobic operation and therapeutic efficacy of deoxynivalenol detoxification in vivo ...
