Reduced cardiovascular mortality at moderate altitude: a putative role of physical activity and body mass

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Benefits of performing physical exercise at moderate altitude. At moderate altitude, increased resting metabolic rate and physical exertion promote physical fitness and exercise tolerance, whereas hypoxia suppresses appetite and elicits adaptations that increase tissue O2 delivery while augmenting O2‐independent ATP production ...

Imaging the Solar Corona from “Within”: A Cutting-edge Approach to Enhance PSP/WISPR Imagery

open access: yesThe Astrophysical Journal Supplement Series
The unprecedented remote-sensing observations obtained by the Wide Field Imager for Solar Probe (WISPR) on board the Parker Solar Probe (PSP) from distances inside Mercury’s orbit are revolutionizing our perception of the fine-scale morphology and ...

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Ergothioneine: Biosynthesis, Molecular Mechanisms, Physiological Function, and Role in Disease

open access: yesMedComm, Volume 7, Issue 9, September 2026.
Ergothioneine is a natural thione antioxidant with significant biomedical potential. By reducing oxidative stress, inflammation, mitochondrial dysfunction, and cellular injury, ergothioneine may support interventions for aging‐related disorders, neurodegeneration, metabolic diseases, and skin protection.
