Designer DNA‐Based Machines

SmartBot, EarlyView.
DNA machinery represents a burgeoning frontier at the intersection of robotics and nanotechnology, evolving from static nanostructure toward dynamic nanorobots. Here, the authors review the comprehensive research pipeline of designer DNA‐based nanomachines, covering the design, analysis, and fabrication. These programmable systems enable transformative

Light‐Guided Molecular Patterning for High‐Throughput Single‐Molecule Mechanical Characterization

Small, EarlyView.
A light‐guided molecular patterning method is presented for high‐throughput single‐molecule characterization. The approach enables scalable and accessible molecular patterning without specialized lithography equipment. Patterned surfaces are compatible with downstream biophysical assays, demonstrated by magnetic tweezers and flow‐based single‐molecule ...

The shibirets4 mutation causes temperature sensitive paralytic and lethal phenotypes in the Queensland fruit fly, Bactrocera tryoni

Insect Science, EarlyView.
Abstract Bactrocera tryoni, the Queensland fruit fly, is among the most damaging insect pests to the Australian horticultural industry as larvae infest ripening fruits or vegetables prior to harvest. Genetic biocontrol using Sterile Insect Technique (SIT) programs have been used to successfully suppress populations, via mass release of factory‐reared ...

A Theoretical Exploration of the Photoinduced Breaking Mechanism of the Glycosidic Bond in Thymine Nucleotide

Molecules
DNA glycosidic bond cleavage may induce cancer under the ultraviolet (UV) effect. Yet, the mechanism of glycosidic bond cleavage remains unclear and requires more detailed clarification. Herein, quantum chemical studies on its photoinduced mechanism are performed using a 5′-thymidine monophosphate (5′-dTMPH) model.

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

Insect Science, EarlyView.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

DNA repair by eukaryotic nucleotide excision nuclease. Removal of thymine dimer and psoralen monoadduct by HeLa cell-free extract and of thymine dimer by Xenopus laevis oocytes.

Journal of Biological Chemistry, 1993
Using a human cell-free extract, we have recently shown that thymine dimers are removed from DNA in oligonucleotides 27-29 nucleotides in length (Huang, J. C., Svoboda, D. L., Reardon, J. T., and Sancar, A. (1992) Proc. Natl. Acad. Sci. U. S. A. 89, 3664-3668).

Integration of epigenetics into ecotoxicology: insights and fundamental research needs

Biological Reviews, EarlyView.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

Unnatural Amino Acid and Emerging Chemistry Approaches to Map RNA–Protein Interactions

Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.
This review highlights emerging chemistries for mapping RNA–protein interactions, including genetically encoded unnatural amino acids, novel photocrosslinkers, and non‐photoactivatable crosslinking systems. We compare their mechanisms, reactivity and applications, outlining how these next‐generation tools enable higher‐resolution, site‐specific ...

Ratio of AT and GC Pairs in the Zones of Open States Genesis in DNA Molecules

Frontiers in Bioscience-Landmark
Background: There is an assumption about the presence of a specific nucleotides sequence in DNA molecule, which contributes to the genesis of open states (OS). In addition, it would be logical to assume that OS zones should form in DNA

Encoding DNA sequences by integer chaos game representation

, 2017
DNA sequences are fundamental for encoding genetic information. The genetic information may not only be understood by symbolic sequences but also from the hidden signals inside the sequences.
