Antiferromagnets have attracted significant attention in the field of magnonics, as promising candidates for ultralow-energy carriers for information transfer for future computing. The role of crystalline orientation distribution on magnon transport has received very little attention. In multiferroics such as BiFeO the coupling between antiferromagnetic and polar order imposes yet another boundary condition on spin transport. Thus, understanding the fundamentals of spin transport in such systems requires a single domain, a single crystal. We show that through Lanthanum (La) substitution, a single ferroelectric domain can be engineered with a stable, single-variant spin cycloid, controllable by an electric field. The spin transport in such a single domain displays a strong anisotropy, arising from the underlying spin cycloid lattice. Our work shows a pathway to understanding the fundamental origins of magnon transport in such a single domain multiferroic.

The duplex-forming behavior of an inchworm-type PNA-PEG conjugate (i-PPc), engineered for the selective recognition of point mutations in DNA, was assessed through thermodynamic analysis employing UV melting curves and circular dichroism spectroscopy. The i-PPc demonstrated the ability to form stable duplexes exclusively with fully complementary DNA sequences, while no hybridization with single-base mismatched sequences. This binary on/off hybridization behavior was maintained even under physiologically relevant conditions (37 °C), thereby illustrating the exceptional point mutation discrimination capability of i-PPc.

Despite its potential as a cancer immunotherapy, wild-type IL-2 is limited by dose-limiting toxicities, including vascular leak syndrome, and its strong activation of regulatory T cells (Tregs), which dampens anti-tumor immunity. These drawbacks are largely driven by IL-2's binding to IL-2Rα, and avoiding this interaction can reduce IL-2-associated toxicities, although it cannot completely eliminate them. To overcome these limitations, βγ-biased IL-2 variants (Non-α-IL-2) have been developed to selectively activate effector T and NK cells.

Aptamers are single-stranded DNA or RNA oligonucleotides that can bind to specific target molecules with high affinity and specificity. Fluorescence DNA aptamer-based biosensors (aptasensors) have emerged as powerful analytical tools for detecting diverse targets, ranging from food contaminants to disease biomarkers, owing to their exceptional specificity, high sensitivity, and cost-effectiveness. This review systematically summarizes recent advances in the design strategies of fluorescence aptasensors, focusing on three key approaches: (1) fluorescence resonance energy transfer-based signal amplification, (2) nanomaterial-enhanced probes, and (3) multi-channel platforms for simultaneous detection.

Parkinson's disease is a prevalent neurodegenerative disease, in which genetic mutations in many genes play an important role in its pathogenesis. Among these, a mutation in the PINK1 gene, a mitochondrial-targeted serine/threonine putative kinase 1 that protects cells from stress-induced mitochondrial dysfunction, is implicated in autosomal recessive Parkinsonism. However, the exact etiology is not well understood.

Background: To investigate covert motor processes, transcranial magnetic stimulation (TMS) studies often use motor-evoked potentials (MEPs) as a proxy for inferring the state of motor representations. Typically, these studies test motor representations of actions that can be produced by the isolated contraction of one muscle, limiting both the number of recorded muscles and the complexity of tested actions. Furthermore, univariate analyses treat MEPs from different muscles as independent, overlooking potentially meaningful intermuscular relationships encoded in MEPs amplitude patterns at the single-trial level.
