Zinc/Silver‐Based Hydrogen Sulfide Trapping as an Alternative to Cadmium for Sulfur Stable Isotope Analysis

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 22, 30 November 2025.
ABSTRACT Rationale Hydrogen sulfide (H2S) sulfur stable isotope ratio (δ34S) analyses use cadmium (Cd) or zinc (Zn) solutions; however, Cd is toxic, and Zn does not display an obvious change in color at low molar H2S inputs. This study (i) developed a non‐toxic, colorimetric mixed zinc/silver (Zn/Ag)‐based method and (ii) evaluated the minimum H2S ...

Probing Intracellular Yeast Metabolism With Deuterium Magnetic Resonance Spectroscopy

open access: yesNMR in Biomedicine, Volume 38, Issue 10, October 2025.
Deuterium magnetic resonance spectroscopy (DMRS) provides a straightforward, noninvasive method for monitoring real‐time metabolic flux. We determined the T1, T2, and chemical shifts for 26 deuterium‐labeled compounds in phosphate‐buffered saline. DMRS showed the consumption of pyruvate, glucose, fumarate, acetone, and nicotinamide, and let us test ...

Parasites Are Paramount: Vertical Trophic Positions of Parasitic Catfishes in a Tropical River Food Web

open access: yesEcology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT The Neotropical catfish family Trichomycteridae contains parasitic fishes that include scale and mucus feeders (subfamily Stegophilinae) and blood feeders (i.e., ‘candirus’, subfamily Vandelliinae). The influence of parasitic catfishes on food web dynamics is unknown.
