A mid‐Cretaceous monocot flower from the Dakota Sandstone of Kansas and its potential implications for the fossil record of palms

American Journal of Botany, EarlyView.
Abstract Premise Although the megafossil flora of the upper Albian–lower Cenomanian Dakota Formation in Kansas is well known for angiosperms, monocots have not been reported previously. Methods A mesofossil flower was discovered by X‐ray analysis of a specimen collected more than a century ago from the Dakota Sandstone of central Kansas.

Construction Trade Work Is Associated With Accelerated Decline in Kidney Function

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Construction workers are exposed to airborne particulates, organic solvents, and metals—agents linked to elevated risk of chronic kidney disease (CKD). Few studies have evaluated whether construction trade work is associated with longitudinal changes in estimated glomerular filtration rate (eGFR), a key indicator of kidney function.

Molecular Details of RNA Interactions With FUS Condensates Altering Assembly, Dynamics, and Aggregation

Angewandte Chemie, EarlyView.
Using NMR and molecular simulations, we map how RNA engages FUS LC‐RGG1 within condensates through electrostatic, π‐stacking, and polar contacts. These multivalent RNA contacts help stabilize RNA within FUS condensates while also reshaping condensate composition and dynamics.

Ag─S Sites Steer Furfural Electroreduction to Furfuryl Alcohol

Angewandte Chemie, EarlyView.
A simple sulfide incorporation strategy turns silver into a highly active and selective catalyst for furfural electroreduction to furfuryl alcohol. Experiments combined with density functional theory reveal how isolated S sites promote hydrogenation while suppressing hydrofuroin coupling, enabling selective biomass upgrading.

Beyond Formate Trapping: A Mechanistic Framework for Homogeneous CO2‐to‐Methanol Conversion With First‐Row Transition Metals

Angewandte Chemie, EarlyView.
This review shows that converting CO2 into methanol with catalysts based on abundant first‐row metals requires more than overcoming formate formation. Success depends on balancing hydrogen activation, intermediate reactivity, product release, and catalyst stability.
