Invited for this month's cover picture is the group of Dr. Satoko Hayashi at Faculty of Systems Engineering and Chemistry at Wakayama University. The cover picture shows the linear Se σ(16c-30e) interactions, illustrated by the molecular graph type on the optimized structure of the dicationic octamer of 1,5-(diselena)cane. HOMO-1 of ψ is drawn on the structure, which is located predominantly on the Se atoms. The optimized structure is stable, due to the nice engagement between the (CH ) moieties. The contour maps of ρ(r) are also drawn on the molecular C planes of the dicationic dimer and trimer to demonstrate clearly the existence of the interactions between Se atoms.

Intra-host viral variability is related to pathogenicity, persistence, drug resistance, and the emergence of new clades. This work reviews the large amount of data on SARS-CoV-2 intra-host variability accumulated to date, addressing known and potential implications in COVID-19 and the emergence of VOCs and lineage-defining mutations. Topics covered include the distribution of intra-host polymorphisms across the genome, the corresponding mutational signatures, their patterns of emergence and extinction throughout infection, and the processes governing their abundance, frequency, and type (synonymous, nonsynonymous, indels, nonsense).

Extreme events influence ecosystem dynamics, but their effects on coastal marine habitats are often poorly perceived compared to their terrestrial counterparts. The detailed study of changes in benthic communities related to these phenomena is becoming urgent, due to the increasing intensity and frequency of hurricanes recorded in recent decades. Slow-growing benthic sessile organisms are particularly vulnerable to mechanical impacts, especially the large long-lived species with branched morphology that structure Mediterranean coralligenous assemblages.

Medical imaging, particularly radiography, is an indispensable part of diagnosing many chest diseases. Final diagnoses are made by radiologists based on images, but the decision-making process is always associated with a risk of incorrect interpretation. Incorrectly interpreted data can lead to delays in treatment, a prescription of inappropriate therapy, or even a completely missed diagnosis.

A tribute to the life and career of Dr Milton Diamond, a leading figure in twin studies of transsexuality and gender identity, is presented. Dr Diamond is famous for revealing the truth about the unsuccessful effort to change a monozygotic male Canadian twin into a female, following accidental ablation of his penis during circumcision. A short summary of recent twin research on human sexuality and transsexuality, focused on Dr Diamond's contributions, is then presented.

Objective: To describe the use of the TISA (Transcutaneous Implant Skin Anomalies) scale by members of the Colombian Association of Otology (ACON) in the evaluation of patients using bone conduction implants.
Methods: A cross-sectional descriptive observational study was conducted among the members of the Colombian Association of Otology. A voluntary survey was performed, where participants evaluated images of patients with transcutaneous bone conduction implants exhibiting different skin conditions.
