Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator–prey conflict within the carnivorous Pinguicula subgenus Temnoceras

American Journal of Botany, EarlyView.
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Solar Flow Synthesis of Polymer Nanoparticles: Scaling Local Experiments to Global Potential

Angewandte Chemie, EarlyView.
The large‐scale sunlight‐induced photochemical synthesis of polymer nanoparticles based on the Diels–Alder step‐growth polymerization of a bismaleimide and a difunctional o‐methylbenzaldehyde in a self‐built solar flow reactor is introduced. Furthermore, a framework is established to translate sunlight‐driven experimental results globally—validated in ...

Dynamischer Austausch von Bindemolekülen steigert die Effizienz der Proteinmarkierung in DNA‐PAINT um das bis zu 15‐Fache

Angewandte Chemie, EarlyView.
Der dynamische Austausch von Bindemolekülen (Dynamic Binder Exchange; DyBE) nutzt transiente Binde–Zielprotein‐Interaktionen, um die Markierungseffizienz in der superauflösenden Mikroskopie um das 15‐Fache zu steigern. DyBE kartiert die Organisation von Rezeptor‐Tyrosinkinasen (RTKs), einschließlich HER2‐Homodimere und EGFR–HER2‐Heterodimere, auf der ...

"Now he walks and walks, as if he didn't have a home where he could eat": food, healing, and hunger in Quechua narratives of madness [PDF]

, 2013
In the Quechua-speaking peasant communities of southern Peru, mental disorder is understood less as individualized pathology and more as a disturbance in family and social relationships. For many Andeans, food and feeding are ontologically fundamental to

Kern‑Schale: Versiegelung nanoporöser Partikel mit semipermeablen Kohlenstoffschichten befreit Hartkohlenstoffanoden von ihrem Dilemma

Angewandte Chemie, EarlyView.
Eine Kern‐Schale‐Strategie wird vorgestellt, um die hohen Verluste nichtgraphitischer Hartkohlenstoffanoden zu überwinden. Aktivkohle wird durch Gasphasenabscheidung mit einer semipermeable Kohlenstoffschicht versiegelt, wodurch die SEI‐Bildung und Natriumspeicherung räumlich getrennt werden.

Redox‐aktivierte Sonden für Hochkontrastige Live‐Bildgebung Postsynaptischer Neuronaler Gerüste

Angewandte Chemie, EarlyView.
Sylives sind modifizierte fluoreszierende Peptide für eine kontrastreiche Live‐Bildgebung inhibitorischer (Gephyrin) und exzitatorischer (PSD‐95) postsynaptischer Gerüststrukturen in nativen Neuronen. Eine saubere Markierung erfordert niedrige Sondenkonzentrationen im Nanomolarbereich, während die Aufnahme mikromolare Konzentrationen zellpenetrierender

Aprovechamiento del biosol producido por biodigestión anaerobia de porquinaza para la fertilización de rábano rojo

Ontare, 2020
Los problemas asociados a la producción masiva de porquinaza en las granjas porcícolas se asocian al mal olor, a la propagación de patógenos y a la contaminación de fuentes hídricas y suelos. Como una solución sostenible se implementó un biodigestor con
