Firm turnover under asymmetric information: Tanzania's agro‐dealer sector
American Journal of Agricultural Economics, EarlyView.Abstract We study firm turnover (i.e., entry and exit) and its consumer implications in a market characterized by asymmetric information. Using a three‐round census of agro‐dealers in Tanzania's Morogoro Region, we document annual firm entry and exit rates of 33% and 17%, respectively.

American Journal of Agricultural Economics, EarlyView.Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Angewandte Chemie, EarlyView.An electron bridge strategy is developed to regulate charge polarization in Pd1 and Ni1 dual single‐atom sites, promoting CO2 reduction, nitrate reduction, and C–N coupling simultaneously. The resulting catalyst achieves efficient urea electrosynthesis with high activity and record durability over 1700 h.

Concurrent Germline RB1 & Mosaic TP53 in a Child With Multiple Childhood Cancers
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT We report a patient with a pathogenic germline variant (PGV) in RB1 and somatic mosaicism for a pathogenic TP53 variant who developed three distinct types of childhood cancer: retinoblastoma, osteosarcoma, and myelodysplastic syndrome (MDS) before the age of 6 years.

Accelerating Phosphate Transport Across Membranes via Synergistic Chemical‐Electrochemical Carriers
Angewandte Chemie, EarlyView.A new membrane design principle based on synergistic chemical and electrochemical carriers is proposed to construct an electro‐driven carrier‐conducting membrane for high‐throughput phosphate transport. Monodispersed ferrihydrite nanoparticles embedded within the membrane act as built‐in phosphate carriers, enabling accelerated phosphate migration via ...
