Controversies Surrounding Critical‐Size Defects: Influence of Age and Biological Characteristics

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 6, June 2026.
ABSTRACT Critical‐size defects (CSDs) in craniofacial reconstruction refer to osseous gaps that fail to heal spontaneously, increasing the risk of neurological impairment and craniofacial dysmorphology. Despite decades of investigation, controversy still exists surrounding the definition of CSDs, with criteria varying across species, experimental ...

Isolation and Structural Characterization of Se‐Hügerschoff Intermediates Derived From 4‐Bromoaniline

open access: yesJournal of Heterocyclic Chemistry, Volume 63, Issue 6, Page 1004-1009, June 2026.
Isolation and characterization of Se‐brominated Hügerschoff intermediates enable structural and mechanistic insight into seleno‐Hügerschoff cyclization to 2‐aminobenzoselenazoles. ABSTRACT A brominated intermediate within the Hügerschoff reaction has long been postulated but never directly observed.

Marine invertebrates and fishes exhibit inconsistent body size responses to ocean acidification

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Body size is a fundamental characteristic of all living organisms that determines physiological functions and life‐history traits. Ecological theory predicts that ocean acidification can cause body size reductions, confirmed by several studies reporting miniaturization in ectotherms.

Direct Evidence for a Carbon–Carbon One‐Electron σ‐Bond, or a Weak Carbon–Carbon Interaction?

open access: yesChemistryOpen, Volume 15, Issue 6, June 2026.
Experiments reporting the existence of a single‐electron C─C σ bond in a synthesized stable radical cation open up new perspectives in the study of the existence of chemical bonds. However, the supporting theoretical results at density functional theory cost do not seem to fully support this evidence.

Headache psychiatry: A structured narrative review and integrative framework

open access: yesPsychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.
Headache disorders are among the most prevalent and disabling neurological conditions worldwide, yet their psychiatric comorbidities remain systematically underrecognized in clinical practice. This narrative review introduces Psychocephalology—a biopsychosocial framework conceptualizing headache through five interacting domains: neurobiology, pain ...

Automated serial electron diffraction: implementation in LibraEDT and its applications

open access: yesJournal of Applied Crystallography, Volume 59, Issue 3, Page 858-868, June 2026.
We describe a continuous serial electron diffraction implementation in LibraEDT that enables automated data collection with real‐time frame evaluation, together with an accessible workflow for subsequent data processing.Serial electron diffraction (SerialED) offers an effective route for structure determination of beam‐sensitive materials, yet its ...
