Using citizen science as a research prioritization tool to detect co‐occurrences of the invasive species Harmonia axyridis

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 ...

Compositional Phenolic Signatures of Antioxidant-Relevant Compounds in Hop (Humulus lupulus L.) Varieties and Local Ecotypes Cultivated in Southern Chile

Antioxidants
Hop (Humulus lupulus L.) cones are increasingly recognized as sources of phenolic compounds relevant to antioxidant-oriented applications beyond their traditional brewing role; however, genotype-dependent chemical diversity remains poorly characterized ...

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.

Development of functional ectopic compound eyes in scarabaeid beetles by knockdown of orthodenticle [PDF]

, 2017
Complex traits like limbs, brains, or eyes form through coordinated integration of diverse cell fates across developmental space and time, yet understanding how complexity and integration emerge from uniform, undifferentiated precursor tissues remains ...

Are i‐Motif Structures in DNA Compatible with Cytosine–Ag(I)–Cytosine Base Pairs?

Angewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
An i‐motif/duplex junction was evaluated with respect to its ability to replace the protons from the hemi‐protonated C:CH+ pairs by AgI ions to form C–AgI–C base pairs. Interestingly, only one such metal‐mediated base pair can be formed before the oligonucleotide rearranges into a duplex structure.

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

Expanding the 2, 2’-bipyrimidine bridged 1D homonuclear coordination polymers family: [MIIbpymCl2] (M=Fe, Co) magnetic and structural characterization [PDF]

, 2013
One pot reaction of hydrated chloride salts of Fe(II) and Co(II) with stoichiometric amounts of 2,2’-bipyrimidine (bpym) in a methanol–acetonitrile mixture afforded the corresponding 1D homonuclear coordination polymers, [μ-(bpym)MCl2]n.
