A Modification-Free Microneedle-Integrated Printed Electrochemical Sensor for Uric Acid Detection in Artificial Skin

Abstract The integration of microneedles (MNs) with electrochemical biosensors is a promising strategy for minimally invasive detection of metabolites from interstitial fluid (ISF). Conventional MN-based sensing platforms typically rely on conductive coatings or surface functiona...

Integrated QTL-seq and transcriptome analyses identify a DUF1677 candidate gene with a Predicted Kelch β-propeller-like fold associated with iron deficiency response in rice

Abstract Iron deficiency is a major abiotic constraint in rice production, especially in direct-seeded and aerobic cultivation systems, yet the genes controlling tolerance, especially at the seedling stage, remain poorly understood. In this study, we screened 116 rice genotypes u...

Two new species of Merogomphus Martin, 1904 (Odonata: Anisoptera: Gomphidae) from the Western Ghats, India

We describe two new species of dragonflies from the Western Ghats Biodiversity Hotspot, Merogomphus aryanadensis sp. nov. from Kerala and M. flavoreductus sp. nov. from Maharashtra, India. Morphologically, these species are closely aligned with M. tamaracherriensis Fraser, 1931,...

Hydrogen Bonds Determining the Conformation of Isolated Amino Acid Residues in Proteins: Re‐Examination of the Fully Extended C5 Structures

Hydrogen bonds contribute substantially to the stabilisation of specific three-dimensional structures of peptides. The C5 hydrogen bond is an intraresidue interaction, which appears to contribute to the stabilisation of fully extended residue conformations, with backbone torsion...

Testing the gearbox hypothesis for insect flight control

Across Diptera, sustained flight relies on stretch-activated asynchronous flight muscles that generate multiple contraction cycles per motor neuron impulse, enabling wingbeat frequencies of ∼100-1000 Hz. These muscles attach to the thorax as indirect flight muscles, driving wing...
