Rangewide responses of Mimulus cardinalis to an extreme heat event

American Journal of Botany, EarlyView.
Abstract Premise Extreme events are an understudied aspect of ongoing anthropogenic climate change that could play a disproportionate role in the threat that rapid environmental shifts pose to natural populations. Methods We exposed plants originating from seeds that were harvested before (ancestors) and after (descendants) multiple extreme heat events

Contrasting effects of experimental warming in the initiation year and the flowering year on flower phenology of boreal understory species

American Journal of Botany, EarlyView.
Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.

Dual Chemical Looping/Catalytic Process for Alkylation of Benzene With Ethane and Propane Yielding Ethylbenzene and Cumene Over Copper‐Containing Mordenite

Angewandte Chemie, EarlyView.
We report a dual chemical looping/catalytic process coupling alkane dehydrogenation with aromatic alkylation over Cu‐mordenite, yielding up to 25% alkylated aromatics with >95% selectivity per cycle. In situ NMR, FTIR spectroscopy, and DFT show alkylation proceeds via a π‐bound Cu(I)–olefin intermediate and Brønsted acid sites.

Delivering a family‐based child mental health promotion program among two resettled refugee communities during the COVID‐19 pandemic: Lessons learned in a hybrid type II implementation‐effectiveness randomized controlled trial

American Journal of Community Psychology, EarlyView.
Abstract Background Resettled refugee families face elevated mental health risks, compounded by structural and cultural barriers. The Family Strengthening Intervention for Resettlement (FSIR), co‐developed with resettled refugee communities, aims to improve family functioning and child mental health.

A General Group Testing Strategy for Discovering Chemical Cooperativity

Angewandte Chemie, EarlyView.
A combinatorial design theory‐based group testing strategy coupled with luminescence screening to uncover cooperative interactions in a large combinatorial space. Iterative deconvolution identifies reactive molecular pairs and enables the discovery of trifluoromethylthiolation (SCF3) reagents.

Polyphenol diet and exercise as neuroprotective factors in a Drosophila model of Alzheimer's disease

Animal Models and Experimental Medicine, EarlyView.
Moderate exercise and low‐dose ellagic acid supplementation improved motor performance, learning, and longevity in a transgenic Drosophila model of Alzheimer's disease. Both interventions showed hormetic effects—that is, beneficial at low levels, but detrimental at higher intensities or doses.

Mechanism of the Photodecomposition of Stable Triarylmethyl Radicals

Angewandte Chemie, EarlyView.
Photolysis of luminescent chlorinated trityl radicals was studied with density functional theory and the decomposition products were isolated and characterized. It proceeds by a 5‐electron electrocyclization then a 1,8‐sigmatropic chloride shift, forming non‐emissive, less stable fluorenyl radicals.
