Development of Single‐Molecule Enzyme Activity Assay for Serine Hydrolases Using Activity‐Based Protein Labeling Probes

Small Methods, Volume 9, Issue 11, November 1, 2025.
This study introduces a single‐molecule strategy using activity‐based probes (ABPs) to sensitively detect accessible enzymes in complex biological systems. The approach successfully visualizes the active forms of PSA and granzyme B, demonstrating its utility for probing protease activity states with high selectivity and sensitivity at the molecular ...

Interstellar Al-26 and excess Mg-26 [PDF]

Evidence of a possible supernova explosion that occured very near the Earth is presented by the presence of radioactive 26 Aluminum (26 Al). The time of the supernova explosion is placed at approximately 100,000 years ago and is partially supported by ...

First Detection of [SI] in Near‐IR JWST Observations of Io in Eclipse, and Comparison With SO Emissions, Evolving Volcanic Eruptions, and Prior UV HST‐STIS [SI] Emissions

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract We observed Io with the James Webb Space Telescope (JWST) NIRSpec/Integral Field Unit (1.0–5.3 μm, R∼2700 $R\sim 2700$) in August 2023 while the satellite was in eclipse. Thermal emission from Kanehekili Fluctus is consistent with the cooling of lava flows after a vigorous eruption in November 2022.

Time resolved 2 million year old supernova activity discovered in Earth's microfossil record

, 2016
Massive stars, which terminate their evolution as core collapse supernovae, are theoretically predicted to eject more than 1E-5 solar masses of the radioisotope 60Fe. If such an event occurs sufficiently close to our solar system, traces of the supernova

NtCML19 Is Recruited by Tobacco to Interact With the Deacetylase Protein RsDN3377 of Rhizoctonia solani AG3‐TB, Inhibiting Fungal Infection

Molecular Plant Pathology, Volume 26, Issue 11, November 2025.
The deacetylase RsDN3377 is recognised by the calcium‐binding protein NtCML19, which enhances host resistance against Rhizoctonia solani infection by inducing cell death and reactive oxygen species (ROS) accumulation. ABSTRACT The necrotrophic fungal pathogen Rhizoctonia solani anastomosis group 3 (AG3‐TB) is a major cause of global tobacco crop yield ...

Boosting POM‐Ionosolv Biorefining of Lignocellulosic Biomass by Using Redox‐Balanced Polyoxometalate Catalysts in Methanolic Ionic Liquid Reaction Media

ChemSusChem, Volume 18, Issue 20, October 23, 2025.
This study presents an advanced iteration of the polyoxometalate (POM)‐Ionosolv concept to generate biobased methyl formate in high yield and a bleached cellulose pulp from lignocellulosic biomass in a single‐step operation by using redox‐balanced POM catalysts and molecular oxygen in alcoholic ionic liquid mixtures.

Diiron Complexes of 3H‐1,2,3,5‐Dithiadiazolines and the Fate of the Parent Dithiadiazolyl: A Crystallographic and Computational Study

European Journal of Inorganic Chemistry, Volume 28, Issue 30, October 22, 2025.
Aryl‐substituted 1,2,3,5‐dithiadiazolyl radicals (4‐RC6H4CN2S2) react with Fe2(CO)9 or Fe3(CO)12 in toluene to form diiron 3H‐1,2,3,5‐dithiadiazolidine complexes with N‐H substituents, resulting in hydrogen‐bonding chains in the solid state. Calculations support direct hydrogen‐atom abstraction from the solvent by a putative diiron dithiadiazolyl ...

Mini Z' Burst from Relic Supernova Neutrinos and Late Neutrino Masses

, 2006
In models in which neutrinos are light, due to a low scale of symmetry breaking, additional light bosons are generically present. We show that the interaction between diffuse relic supernova neutrinos (RSN) and the cosmic background neutrinos, via ...

Evidence for two neutrino mass eigenstates from SN 1987A and the possibility of superluminal neutrinos

, 2015
This paper reports a new phenomenological analysis of the neutrino burst detected from SN 1987 A, and it reveals the presence of two mass eigenstates. The heavier mass eigenstate has $m_H=21.4 \pm 1.2 eV/c^2$, while the lighter one has $m_L=4.0 \pm0.5 eV/
