Regeneration Strategies in Seed Plants: A Continuum Shaping Survival

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Seed plants dominate terrestrial ecosystems in part because regeneration is not a single event, but a coordinated sequence of traits acting across time and space. Here, we synthesize regeneration strategies in seed plants as a continuous, integrated framework spanning pre‐germination regulation, germination timing, seedling emergence, soil seed banking,

Study of prompt gamma and neutron emission for real‐time range verification in proton and carbon‐ion therapy

open access: yesMedical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Accurate range verification is crucial in hadrontherapy to fully exploit the ballistic advantages of charged particles and prevent damage to healthy tissues. Among the proposed approaches, prompt gamma imaging (PGI) has emerged as an effective technique for real‐time monitoring, but its performance is limited by the intense neutron ...
