Stratospheric Aerosol From Above: Laser‐Ablation Mass Spectrometer Samples Polar Vortex Air for the First Time

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract The JGR paper by Lawler et al. (2025, https://doi.org/10.1029/2025jd043530) marks a significant and historic first, the PALMS single‐particle chemical analysis sampling deep stratospheric Arctic vortex air for the first time. The analysis finds ∼90% of sulfate aerosol particles in the deepest stratosphere air (100–130 ppb N2O) are meteoric ...

Rational Design of a Synthetic Galliphore for the Diagnostic Nuclear Imaging and Treatment of Bacterial Infections

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
KO‐NH2 is a synthetic metallophore that preferentially binds Ga3+ over Fe3+ and is recognized by bacterial transporters. Photocrosslinking identifies CirA and Fiu as key uptake proteins in E. coli. KO‐NH2 enables targeted imaging and treatment of E. coli soft tissue infections.

Ultra‐Weak Photon Emission as a By‐Product of Mitochondrial Oxidative Metabolism: Mechanisms, Limits, and Implications

Nanophotonics, Volume 15, Issue 20, 27 October 2026.
Mitochondrial oxidative metabolism generates ROS. Downstream chemiexcitation triplet carbonyls, singlet oxygen; produces ultra‐weak photon emission (UPE). Energetic bounds restrict well‐coupled respiration to extremely weak, red/NIR‐biased emission. Stronger visible UPE indicates elevated oxidative flux, linking measured photon counts to redox state ...
