Diazirines Beyond Photoaffinity Labeling: A Comprehensive Overview of Applications in Biological Sciences, Materials Chemistry, and NMR‐Spectroscopy

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.

Sampling the volcanic plumes at Io: Impact speeds and shock conditions

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 2, Page 241-271, February 2026.
Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...

Test–Retest Reliability of Maximal and Rapid Knee Extensor Force Production: Influence of Verbal Instruction and Trial Selection Criteria

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.
ABSTRACT Reliable assessments of maximal and rapid muscle strength are essential for evaluating neuromuscular performance and adaptations. This study examined the effects of verbal instruction and trial selection criteria on performance outcomes and intersession test–retest reliability during maximal isometric knee extensor testing.

Endurance Training in Olympic Winter Sports: A Narrative Review of the Current Literature and Future Research Priorities

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.
ABSTRACT The Milano‐Cortina 2026 Winter Olympics present an opportunity to synthesize evolving paradigms in endurance training within the broader context of long‐term athlete development. As Olympic winter sports span from endurance‐limited events to disciplines in which aerobic fitness primarily serves as a feeder capacity, a single training model is ...

Linking systemic metabolic state to long‐term motor memory: Insights from respiratory exchange ratio and glucose manipulation

open access: yesThe Journal of Physiology, Volume 604, Issue 3, Page 1428-1446, 1 February 2026.
Abstract figure legend The brain is a major energy consumer relying primarily on carbohydrates. This exceptional metabolic demand suggests that its functional state, which includes cognitive processes such as motor memory acquisition and retention, should be observable in the body's systemic metabolism. To explore this link, we investigated whether the

Ab Initio Molecular Dynamics Study of Quadrupolar Spin Relaxation in an Ionic Liquid

open access: yesJournal of Computational Chemistry, Volume 47, Issue 3, 30 January 2026.
This study presents a methodology for describing the relaxation of nuclear spins (with I > 1/2), applicable to ionic liquids of a general nature. Based on ab initio molecular dynamics, we demonstrate the importance of explicit solvation in calculating the relaxation times of the quadrupolar mechanism.
