Insect Conservation and Diversity, Volume 19, Issue 2, Page 452-459, March 2026.We studied co‐occurrences and potential novel interactions between the invasive ladybird Harmonia axyridis and local biota (plants, arthropods and fungi) across Argentina using citizen science records. We detected co‐occurrences (mainly Asteracea and Aphididae) and previously unreported interactions (predation, parasitism, interspecific mating and ...

Sind i‐Motiv‐Strukturen in DNA kompatibel mit Cytosin–Ag(I)–Cytosin‐Basenpaaren?
Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.Ein i‐Motiv/Duplex‐Konjugat wurde hinsichtlich seiner Fähigkeit untersucht, die Protonen der hemiprotonierten C:CH+‐Basenpaare durch AgI‐Ionen zu ersetzen, um C–AgI–C‐Basenpaare zu bilden. Interessanterweise wird nur ein einziges solches Basenpaar gebildet, bevor sich das Oligonukleotid in eine Duplexstruktur umlagert.

Uptake of Hg2+ by picocyanobacteria in natural water from four Andean lakes
E3S Web of Conferences, 2014 In lake food webs, planktonic bacteria and algae represent the greatest bioconcentration step for Hg2+ and monomethyl-Hg (MeHg). As they are the most abundant organisms in planktonic trophic webs and also the main food resource for herbivorous plankton ...

Inducing Chirality and Chiral Instabilities in Ferrogels with Homogenous Magnetic Fields
Advanced Functional Materials, Volume 36, Issue 6, 19 January 2026.By pre‐aligning magnetic particles into chains, significant chiral deformations are induced by fixing the base of a cylindrical actuator and applying a homogeneous magnetic field. Subsequent base rotation can drive the system into metastable states. Further rotation or reduction of field strength triggers a chiral instability, characterized by a switch
