DNA computing is a novel computing method that does not rely on traditional computers. The design of DNA sequences is a crucial step in DNA computing, and the quality of the sequence design directly affects the results of DNA computing. In this paper, a new constraint called the consecutive base pairing constraint is proposed to limit specific base pairings in DNA sequence design. Additionally, to improve the efficiency and capability of DNA sequence design, the Hierarchy-ant colony (H-ACO) algorithm is introduced, which combines the features of multiple algorithms and optimizes discrete numerical calculations. Experimental results show that the H-ACO algorithm performs well in DNA sequence design. Finally, this paper compares a series of constraint values and NUPACK simulation data with previous design results, and the DNA sequence set designed in this paper has more advantages.

Background: Photoplethysmography (PPG) signals captured by wearable devices can provide vascular age information and support pervasive and long-term monitoring of personal health condition.
Objective: In this study, we aimed to estimate brachial-ankle pulse wave velocity (baPWV) from wrist PPG and electrocardiography (ECG) from smartwatch.
Methods: A total of 914 wrist PPG and ECG sequences and 278 baPWV measurements were collected via the smartwatch from 80 men and 82 women with average age of 63.

Globular proteins, traditionally regarded as non-structural biomolecules due to the limited load-bearing capacity in their monomeric states, are increasingly recognized as valuable building blocks for functional-mechanical materials. Their inherent bioactivity, chemical versatility, and structural tunability enable the design of materials that combine biological functionality with tailored mechanical performance. This review highlights recent advances in engineering globular proteins-spanning natural systems (serum albumins, enzymes, milk globulins, silk sericin, and soy protein isolates) to recombinant architectures including tandem-repeat proteins-into functional-mechanical platforms.

G-quadruplexes (G4) are four-stranded nucleic acid structures formed within sequences containing repeated guanine tracts separated by intervening loop regions. Abundant in the human genome, they play crucial roles in transcription regulation and genome maintenance. Although theoretically capable to adopt 26 different folding topologies─primarily differing in loop arrangements─only 14 of these have been observed experimentally.

Developing artificial hosts with temperature-driven conformational switching behaviors facilitates our understanding of the temperature-dependent allostery and adaptation mechanisms in natural recognition systems. Herein, we report the design and synthesis of three pairs of water-soluble, enantiomeric binaphthalene-based tetraimidazolium macrocycles (SS/RR-1•4Cl- - SS/RR-3•4Cl-) as artificial hosts for exploring sequence-selective recognition of dinucleotides in aqueous media. Owing to the reversible rotational conformation of axially chiral binaphthyl units, SS-1•4Cl- demonstrates the conformational switching, converting from cis-conformation (SS-1) to trans-conformation (SS-1) by increasing temperature, thereby causing the recognition cavity to transition from a closed to an open state.

Background: Soil salinization represents a critical global challenge to agricultural productivity, profoundly impacting crop yields and threatening food security. Plant salt-responsive is complex and dynamic, making it challenging to fully elucidate salt tolerance mechanism and leading to gaps in our understanding of how plants adapt to and mitigate salt stress.
Results: Here, we conduct high-resolution time-series transcriptomic and metabolomic profiling of the extremely salt-tolerant maize inbred line, HLZY, and the salt-sensitive elite line, JI853.
