as energy reservoirs, structural components, and nucleic‑acid backbones in living systems. RNA incorporates ribose, while DNA relies on the related deoxyribose. Though erythrulose itself is not part of either polymer, its chemistry aligns with the...

the diversification of these fish occurred long after the event. Comprehensive Evolutionary Timeline By integrating DNA sequences with fossil records, the team assembled the most detailed time‑calibrated phylogeny for the family Scombridae, which...

as Mesoplodon ginkgodens, directly linking the species to the BW43 signal for the first time. Concurrently, environmental DNA (eDNA) collected from surrounding water matched the same species, providing independent verification. (a) A close-up of the...

identity of Yatzila remains unknown, and researchers hope a 2027 expedition will allow them to extract a tooth for ancient DNA analysis. For the time being, the team has refrained from removing the remains, retrieving only a single ceramic fragment for...

than its smaller counterparts. Implications for pre‑biotic chemistry While erythrulose is not a direct component of DNA or RNA, ketose sugars like it can isomerize into aldose forms under aqueous conditions, potentially feeding into synthetic routes...

While the case centered on visible aging, ultraviolet radiation also inflicts damage beneath the surface. UVA contributes to DNA injury and cellular stress, whereas UVB is strongly associated with mutations that can lead to skin cancer. The report did...
