Early evolutionary history of the seed
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

A one‐pot metal–ammonia synthesis enables uniform Mn2O3 nanoparticle deposition on activated carbon, yielding composites with excellent electrochemical performance in supercapacitors. The method maximizes manganese utilization, eliminates toxic solvents, and achieves 34% of the theoretical maximum capacitance, significantly outperforming existing Mn–C ...
