The Aco2 gene of Schizosaccharomyces pombe was formed by gene fusion between curious partners, namely genes encoding the enzyme aconitase and a mitochondrial ribosomal protein. In addition to a full-length transcript, a truncated mRNA encoding only the N-terminal aconitase domain is produced by polyadenylation at an…

Isozymes are enzymes that differ in sequence but catalyze the same chemical reactions. Despite their apparent redundancy, isozymes are often retained over evolutionary time for reasons that can be unclear. We find that, in yeast, isozymes are strongly enriched in central carbon metabolism. Using a gene expression…

The two principal growth regulators cytokinins and ethylene are known to interact in the regulation of plant growth. However, information about underlying molecular mechanism and positional specificity of the cytokinin/ethylene crosstalk in root growth control is scarce. We have identified spatial specificity of…

Ethylene is a central plant hormone that orchestrates growth, development, senescence, and stress responses. Because it is gaseous, ethylene must be synthesised on demand, yet the catalytic and regulatory mechanisms of its biosynthetic enzyme, 1-aminocyclopropane-1-carboxylic acid oxidase (ACO), remain poorly…

Traditional gas exchange metrics, such as the alveolar-arterial (A–a) gradient (ΔP), fail to account for systemic oxygen extraction or ventilatory adequacy, thereby limiting their diagnostic precision in complex respiratory or circulatory pathologies. We propose and derive the corrected oxygenation gradient (COG), a…

Technological and medical advances over the past few decades epitomize human capabilities. However, the increased life expectancies and concomitant land-use changes have significantly contributed to the release of ~830 gigatons of CO2 into the atmosphere over the last three decades, an amount comparable to the prior…

We report a highly efficient approach to carbon capture and sequestration via the water catalyzed conversion of basic oxygen steel (BOS) slag and CO2 into CaCO3 and volumetrically stable aggregate for road construction using the Zero-Air-Pollution-Carbon-Capture-Capsule (ZAP-C3) units. The overall transformation is…

Electrochemically mediated carbon capture (EMCC) offers a promising alternative to thermochemical carbon capture methods due to its higher energy efficiency and the ability to operate under standard conditions. Graphitic electrodes functionalized with redox-active organic (RAO) capture agents offer a unique opportunity…

We present two novel experimental techniques designed to quantify the contributions of nucleophilicity-swing and pH-swing mechanisms to carbon capture in the electrochemical aqueous quinone-based CO2 capture process. Through thermodynamic analysis, we elucidate the intricate interplay between these two mechanisms, and…

The mechanism of Supercapacitive Swing Adsorption (SSA) has been investigated by pH measurements and acid-base titrations of water-extracted, charged activated carbon electrodes at voltage windows varying from 0-0.5V and 0-1.4V. 15%CO2/85%N2 mixtures and pure N2 were used as feed gases. Deionized water extracts from…

Carbon dioxide capture is an important greenhouse gas mitigation technology that can help limit climate change. The design of improved capture materials requires a detailed understanding of the mechanisms by which carbon dioxide is bound. Nuclear magnetic resonance (NMR) spectroscopy methods have emerged as a powerful…

Carbon monoxide is a colorless, odorless, and poisonous gas, responsible for approximately 100,000 emergency room visits and over 420 deaths in the U.S. each year. Both carbon monoxide and oxygen bind to the ferrous ions in hemoglobin, but carbon monoxide has a significantly higher affinity. Extensive research has been…

17O NMR spectroscopy is emerging as a powerful probe of the chemistry of CO2 capture and storage materials. However, the technique is currently underutilised, owing to (i) challenging spectral interpretation of quadrupolar nuclei (I = 5/2), especially when multiple oxygen environments are present, and (ii) the need for…
