Utterance evolution: the road to generative, combinatorial communicators

open access: yesBiological Reviews, EarlyView.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

(NH4)2[Tc2O2(S2O7)4]: An Unexpected Technetium(V)‐Sulfate From the Reaction of (NH4)(TcO4) With SO3

open access: yesChemistry – A European Journal, EarlyView.
The reaction of the radioactive pertechnetate (99TcO4)− with the oxidizer SO3 leads to blue crystals of (NH4)2[Tc2O2(S2O7)4]. The complex dimeric [Tc2O2(S2O7)4]2− anion exhibits the technetium in the oxidation state V, showing that reduction occurs during the reaction.

Synthesis and Characterization of Carbazole‐Containing Aza[7]helicenes

open access: yesChemistry – A European Journal, EarlyView.
Double ortho fusion led to different aza[7]helicene frameworks showing strong acidochromic behavior, singlet excited energies being more than twice the triplet energy, and high racemization barriers, allowing chiral resolution and ECD measurements. ABSTRACT Azahelicenes have attracted significant interest due to their intrinsic axial chirality and ...

Asexual reproduction and molecular systematics of the sea anemone Anthopleura krebsi (Actiniaria: Actiniidae)

open access: yesRevista de Biología Tropical, 2003
In this paper we use allozyme analyses to demonstrate that individuals in Anthopleura krebsi aggregates are monoclonal. Additionally, sympatric samples of the red and the green colour-morphs of A.

Variable Temperature Studies of Two Calcium Uranates α‐Ca3UO6 and Ca2UO5

open access: yesChemistry – A European Journal, EarlyView.
The structures and thermal responses of the calcium uranates α‐Ca3UO6 and Ca2UO5 were investigated using in situ synchrotron x‐ray diffraction and neutron powder diffraction. Despite the very similar chemical compositions, the structural response of the two calcium uranates is shown to be complex and varied.

Cost‐Effective Solid‐State NMR Of Fungal Glucans: A Case Study On Schizosaccharomyces pombe

open access: yesChemistry – A European Journal, EarlyView.
A cost‐effective solid‐state NMR strategy enables replication and semi‐quantitative assessment of inherent variation of the fungal cell wall. Whole cell and cell wall extractions yield subtly different compositional differences, revealing molecular adaptations invisible to microscopy.

Engineering and Characterization of a Fluorescent Fission Yeast Arp2/3 Complex for Single Molecule Mechanistic Investigations

open access: yesCytoskeleton, EarlyView.
ABSTRACT Arp2/3 complex is a seven‐component protein complex that facilitates the assembly of branched actin filament networks by binding to pre‐existing “mother” actin filaments and initiating the nucleation of new branched “daughter” filaments. Arp2/3 complex must be activated by a nucleation promoting factor such as the WASP/Scar protein family. The

The Electronic Spin State of Diradicals Obtained from the Nuclear Perspective: The Strange Case of Chichibabin Radicals

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The electronic spin state of two Chichibabin radicals is investigated using 2‐dimensional hyperfine correlated Electron Nuclear Double Resonance. The protons (I=1/2) act as a reference for the electronic spin quantum number (S) via their hyperfine interactions.

Novel Organelle‐Based Intracellular Immunity With Mechanistic and Therapeutic Implications

open access: yesBarrier Immunity, EarlyView.
A conceptual framework illustrating how PAMPs/DAMPs initiate barrier, innate, adaptive, and intracellular immune responses, with organelle‐based intracellular immunity serving as a central integrator linking metabolism, inflammatory signaling, and therapeutic interventions to restore immune homeostasis.
