Stem Cell Differentiation Disperses Transcriptional Clusters via a Conserved Surface‐Condensate Trajectory

Advanced Science, Volume 13, Issue 49, 3 September 2026.
Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...

An Implantable Phototriggered Prodrug Depot Patch Enables Actively Programmable Drug Release for Post‐Myocardial Infarction Therapy

Advanced Science, Volume 13, Issue 51, 14 September 2026.
An implantable phototriggered prodrug depot patch (iPDP) is presented that enables actively programmable drug release post‐implantation. Covalently conjugated prodrug ensures minimal leakage; illumination parameters serve as a code to precisely control dose per release.

Efficacy of Painting Wind Turbine Blades as a Mitigation Measure to Reduce Bird Collisions in a Mediterranean Wind Farm

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Bird mortality due to collisions with wind turbines necessitates the implementation of measures to mitigate this impact. Blade patterning has shown to be a promising measure to increase turbine visibility to birds and reduce collisions. Employing a Before–After–Control–Impact experiment using long‐term fatality searches, bird fatality rates were ...

Early Bird Special: Quantifying Tiger Shark Predation on Albatross Fledglings at Kure Atoll

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Predators are often assumed to concentrate where prey are most abundant, but the most abundant prey may not be the easiest to catch. We studied tiger sharks hunting young albatross seabirds during an albatross fledging season at Kure Atoll, Hawaii. Surprisingly, sharks arrived and largely departed before fledgling numbers peaked and predation risk was ...

Unearthing Forest History: Integrating Soil Charcoal Macrofossils and Pollen Reveals Delayed Forest Responses to Holocene Climatic Transitions in Boreal–Temperate Ecotone

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study reconstructs long‐term vegetation dynamics at the boreal–temperate forest ecotone in eastern Canada using soil charcoal, pollen records, and forest inventories. Results reveal a delayed expansion of thermophilous tree species and a late borealization of the landscape in relation to climate change, alongside recent stand‐scale shifts driven ...
