Article Abstract
Plants grow and reproduce within a highly dynamic environment that can see abrupt changes in conditions, such as light intensity, temperature, humidity, or interactions with biotic agents. Recent studies revealed that plants can respond within seconds to some of these conditions, engaging many different metabolic and molecular networks, as well as rapidly altering their stomatal aperture. Some of these rapid responses were further shown to propagate throughout the entire plant via waves of reactive oxygen species (ROS) and Ca that are possibly mediated through the plant vascular system. Here, we propose that the integration of these signals is mediated through pulses of gene expression that are coordinated throughout the plant in a systemic manner by the ROS/Ca waves.

Circulating tumor cells (CTCs) carry intact tumor molecular information, making them invaluable for personalized cancer monitoring. However, conventional capture methods, relying on passive diffusion, suffer from low efficiency due to insufficient collision frequency, severely limiting clinical utility. Herein, a magnetic micromotor-functionalized DNA-array hunter (MMDA hunter) is developed by integrating enzyme-propelled micromotors, magnetic nanoparticles, and nucleic acid aptamers into distinct functional partitions of a DNA tile self-assembly structure.

Singlet oxygen (O) plays a crucial role in cancer chemotherapy and ROS biology, driving the need for highly specific probes to monitor its dynamics in real time. Herein, we developed the ratiometric fluorescent probe NAP-t-PY, utilizing a 2-pyridone recognition unit. The probe's 1-methyl-3-benzyl-2-pyridone moiety reacts specifically with O [4 + 2] cycloaddition, forming the endoperoxide NAP-t-PY-EP.

Effective locomotion requires physiological systems to adapt to instabilities. While gait perturbation recovery often appears rapid, it is possible that longer-lasting effects may be present. Therefore, this study explored recovery trends of gait dynamics following an experimenter-induced perturbation.

Mustard agents, including sulphur mustard (SM) and nitrogen mustard (NM), are chemical warfare agents that can cause blistering of the skin and mucous membranes upon contact. Although SM and NM both have dermal effects, their medical management of systemic poisoning differs significantly. A rapid and simple method for detecting and discriminating between SM and NM would be greatly valuable.

Salicylic acid (SA) is a critical phytohormone involved in plant growth, development, and defense responses, making its precise quantification essential for both agricultural management and environmental monitoring. Here, we report a novel label-free near-infrared aptasensor (NIRApt) for the rapid and sensitive detection of SA, utilizing a rationally selected triphenylmethane (TPM) dye. Through systematic screening, ethyl violet (EV) was identified as the optimal fluorophore, showing pronounced fluorescence enhancement upon binding to a SA-specific aptamer.
