Pyridinol, a coordinating zwitter-ionic species serves as stoichiometrically loadable and non-leachable proton carrier. The partial replacement of the pyridinol by stronger hydrogen bonding, coordinating guest, ethylene glycol (EG), offers 1000-fold enhancement in conductivity (10(-6) to 10(-3) Scm(-1)) with record low activation energy (0.11 eV). Atomic modeling coupled with (13)C-SSNMR provides insights into the potential proton conduction pathway functionalized with post-synthetically anchored dynamic proton transporting EG moieties.

Multidrug-resistant (MDR) bacteria, especially , are a major contributor to healthcare-associated infections globally, posing significant treatment challenges. This study explores the efficacy of (-)-epigallocatechin gallate (EGCG), a natural constituent of green tea, in combination with ampicillin (AMP) to restore the effectiveness of AMP against 40 isolated MDR strains. Antimicrobial activity assays were conducted to determine the minimum inhibitory concentrations (MIC) of EGCG using the standard microdilution technique.

Extreme cold events, becoming more frequent, affect plant growth and development. Much is known about C-repeat binding transcription factor (CBF)-dependent cold-signaling pathways in plants. However, the CBF-independent regulatory pathway in angiosperms is unclear, and the cold-signaling pathways in non-angiosperms lacking CBFs, such as the extremely cold-tolerant desert moss Syntrichia caninervis, are largely unknown.

Most molecules and dielectric materials have characteristic bond vibrations or phonon modes in the mid-infrared regime. However, infrared absorption spectroscopy lacks the sensitivity for detecting trace analytes due to the low quantum efficiency of infrared sensors. Here, we report mid-infrared photothermal plasmonic scattering (MIP-PS) spectroscopy to push the infrared detection limit toward nearly a hundred molecules in a plasmonic nanocavity.

The efficiency and accuracy of CRISPR-Cas9 targeting varies considerably across genomic targets and remains a persistent issue for using this system in cells. Studies have shown that the use of 5' truncated single guide RNAs (sgRNAs) can reduce the rate of unwanted off-target recognition while still maintaining on-target specificity. However, it is not well-understood how reducing target complementarity enhances specificity or how truncation past 15 nucleotides (nts) prevents full Cas9 activation without compromising on-target binding.

Article Synopsis
- - Human exposure to rare earth elements, particularly lanthanum, cerium, and yttrium, is rising due to their use in various industries, but long-term health effects of mixed exposures remain largely unstudied.
- - A study using LO-2 cell line showed that exposure to LCY mixtures increased oxidative stress and activated the NRF2 pathway, affecting cell cycle progression after 30 to 40 passages.
- - While LCY mixtures did not lead to malignant transformation or tumor growth in mice, they did enhance cell proliferation and migration, suggesting potential health risks that require further investigation.
