In vivo quantification of mitochondrial O2 affinity in human skeletal muscle using 1H‐magnetic resonance spectroscopy of deoxy‐myoglobin

open access: yesThe Journal of Physiology, Volume 604, Issue 12, Page 4876-4888, 15 June 2026.
Abstract figure legend This graphical abstract illustrates a novel, non‐invasive approach to quantify mitochondrial oxygen (O2) affinity in vivo in human skeletal muscle using 1H magnetic resonance spectroscopy (1H‐MRS) of deoxymyoglobin (dMb). During brief arterial occlusion, dMb kinetics were used to simultaneously estimate intracellular oxygen ...

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.

Unlocking the Functionalization and Reactivity of Ethylene Bridges in [2.2]Paracyclophanes: Strategies and Challenges

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 20, 27 May 2026.
Bridging the gap. Beyond deck functionalization, the ethylene bridges of [2.2]paracyclophanes offer a largely unexploited reactivity landscape. This review showcases strategies to functionalize these bridges and leverage them to build novel cyclophane architectures.

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

open access: yesChemistry – A European Journal, Volume 32, Issue 19, 22 May 2026.
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.
