Fast single atom imaging for optical lattice arrays.

High-resolution fluorescence imaging of ultracold atoms and molecules is paramount to performing quantum simulation and computation in optical lattices and tweezers. Imaging durations in these experiments typically range from a millisecond to a second, significantly limiting the cycle time. In this work, we present fast, 2.

Comprehensive evaluation of lifespan-extending molecules in C. elegans.

The nematode C. elegans has long served as a gold-standard model organism in aging research, particularly since the discovery of long-lived mutants in conserved aging pathways including daf-2 (IGF1) and age-1 (PI3K). Its short lifespan and small size make it highly suitable for high-throughput experiments.

Development of tetracycline analogues with increased aqueous stability for the treatment of mycobacterial infections.

Tetracycline analogs from the minocycline family have recently shown promise for the treatment of non-tuberculous mycobacterial infections. However, current tetracycline and minocycline therapeutics can be limited by tolerability, stability, or inactivation by TetX. In this study, a series of novel 9-heteroaryl substituted minocycline analogs were designed and synthesized, which resulted in analogs with good in vitro activity against Mycobacterium tuberculosis and Mycobacterium abscessus, stability in water for more than 7 days, avoidance of TetX inactivation in M.

Chemical genetic analysis of enoxolone inhibition of Clostridioides difficile toxin production reveals adenine deaminase and ATP synthase as antivirulence targets.

Toxins TcdA and TcdB are the main virulence factors of Clostridioides difficile, a leading cause of hospital-acquired diarrhea. Despite their importance, there is a significant knowledge gap of druggable targets for inhibiting toxin production. To address this, we screened nonantibiotic phytochemicals to identify potential chemical genetic probes to discover antivirulence drug targets.
