Synthesis technique and electron beam damage study of nanometer-thin single-crystalline thymine
Structural DynamicsSamples suitable for electron diffraction studies must satisfy certain characteristics such as having a thickness in the range of 10–100 nm. We report, to our knowledge, the first successful synthesis technique of nanometer-thin sheets of single ...

Spectroscopic analysis of bacterial photoreactivation
Photochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.

Direct evidence of singlet molecular oxygen [O2 (1Δg)] production from UVA excited 6‐thioguanine
Photochemistry and Photobiology, EarlyView.6‐Thioguanine (6‐TGua) is incorporated into DNA as a purine analogue, inhibiting cell replication. Patients treated with 6‐TGua are more prone to developing skin cancer due to the photoexcitation of 6‐TGua by UVA radiation (as illustrated in the Jablonski diagram). Upon exposure to UVA, the excited 6‐TGua generates 1O2.

Ecology and Evolution, Volume 16, Issue 2, February 2026.We describe Salmacina stellaebayensis n. sp. from Mauritania's Baie de l'Étoile and provide the first complete mitochondrial genome for the genus Salmacina. The species forms distinctive macroid colonies in Cymodocea nodosa seagrass meadows, offering new insights into serpulid life history and habitat specialization.

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.ABSTRACT Epigenetic aging models hold great promise for enhancing many aspects of wildlife research and management. However, their utility is limited by the need to train models using known‐aged animals, which are rare among wildlife species. We present a novel approach to developing methylation‐based age prediction models that enables us to train ...

A Novel Human Cellular System for Studying Normal Aging and for Anti‐Aging Discovery
Aging Cell, Volume 25, Issue 2, February 2026.This study introduces a human cellular aging model using placental trophoblasts (hTSC‐STBs) that mimics key aging features like senescence and genomic instability. It aligns with human tissue aging and responds to anti‐aging treatments, offering a scalable platform to screen potential therapies and bridge lab findings to clinical applications ...
