Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract The Laschamps geomagnetic excursion (≈41,000 years BP) was a period of significant weakening and incomplete reversal of the Earth's magnetic field. The weakening substantially reduced geomagnetic shielding against cosmic rays (CRs), which contribute to phenomena at Earth, such as cosmogenic isotope production, and atmospheric ionisation and ...

The HIF‐1α Pathway Regulates Satellite Cell Fate During Aging Through Histone Lactylation
Aging Cell, Volume 25, Issue 2, February 2026.FG‐4592–induced activation of HIF‐1α enhances anaerobic glycolysis and promotes lactate‐driven PAX7 lactylation, thereby boosting satellite cell activity and counteracting age‐related muscle decline. ABSTRACT Aging‐associated sarcopenia is driven in part by the progressive loss of type II glycolytic fibers and the functional decline of their resident ...

THE SLOW DEATHS FROM CLIMATE CHANGE: A Planetary View from Papua New Guinea
Cultural Anthropology, Volume 41, Issue 1, Page 57-81, February 2026.ABSTRACT How do we tell the stories of climate change? This essay explores the slow violence and death experienced by marginalized, racialized, indigenous bodies as climate change differentially impacts communities across the globe. Paying attention to locations beyond the spectacular events that have come to be associated with climate change, the ...

Formation of Uranium Pinacolate from the Reductive Coupling of Acetone
Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.Uranium(III) cyclopentadienyl complexes are shown to react with acetone in a pinacol coupling, forming uranium pinacolate complexes. Single crystals obtained from the reaction are the first direct structural proof of the previously proposed metallapinacolate intermediate. 1,2‐Diols are elemental building blocks in organic synthesis.

Stabilizing Anion–Anion Aggregates via Dihydrogen Bonds in Non‐Classical Inorganic Molecules
Aggregate, Volume 7, Issue 1, January 2026.Despite Coulomb's law, the anionic [o‐FESAN]− cluster forms stable anti‐electrostatic aggregates via short dihydrogen bonds. Experimental (nuclear magnetic resonance, dynamic light scattering, and X‐ray diffraction) and theoretical (density functional theory) studies reveal that C–H···H–B interactions overcome long‐range repulsion, enabling cluster ...

OBSERVATIONS OF NON TYPICAL MASERS AT THE RT-22 RADIO TELESCOPE IN 2004–2013
Radio Physics and Radio Astronomy, 2017 Purpose: Some peculiarities of emission of Class I methanol masers on the 80–71A+ transition at 95 GHz in sources closely associated with protostar-forming regions and in supernova remnants are studied.

Logarithmic and Strong Coupling Models in Weyl‐Type f(Q,T)$f(Q,T)$ Gravity
Annalen der Physik, Volume 538, Issue 1, January 2026.This work explores Weyl‐type f(Q,T) gravity using recent observational datasets — CC, Pantheon+, Union 3.0, and DESI DR2. Through MCMC analysis of logarithmic and strong coupling models, the study reveals a transition from deceleration to acceleration, quintessence‐to‐phantom dynamics, and late‐time consistency with LCDM, offering a geometry‐driven ...

The origin of cosmic rays and TeV gamma-ray astronomy
EPJ Web of Conferences, 2013 Cosmic rays are accelerated to high energies in Galactic and extragalactic objects like Supernova remnants (SNR) and active galactic nuclei (AGN). How these accelerators work and how efficient they accelerate different types of particles to energies of ...
