A Solar Analog Model for Decrease in Far Ultraviolet Irradiance Under a Grand Minimum

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Solar analog field stars having a range of magnetic activity can provide an estimate of solar spectral irradiance (SSI) variability relevant to understanding the Sun's influence on terrestrial climate. This approach is particularly useful for far ultraviolet (FUV) irradiance that cannot be observed from the Earth surface.

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

Ecological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Personalization and Fortification of In‐Space Manufactured Emulsified Beverages for Long‐Term Space Travel

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT The current trend of individualized food items (nutrient content and flavor) can be particularly valuable to support people's health and well‐being in isolated environments where access to fresh foods and diverse nutrition is difficult. At the same time, bioactive compounds and micronutrients can be employed to countermeasure any health ...

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, Volume 111, Issue 9, Page 4126-4139, 1 September 2026.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Stellar population of the irregular galaxy IC 10 [PDF]

Astronomy Letters, 2009
Based on our observations with the 6-m BTA telescope at the Special Astrophysical Observatory, the Russian Academy of Sciences, and archival Hubble Space Telescope images, we have performed stellar photometry for several regions of the irregular galaxy IC 10, a member of the Local Group.

The stellar structure of irregular galaxies. Face-on galaxies

Astronomy Reports, 2005
Stellar photometry of nearby irregular galaxies of the Local Group is used to identify and study the young and old stellar populations of these galaxies. An analysis of the spatial distributions of stars of different ages in face-on galaxies shows that the young stellar populations in irregular galaxies are concentrated toward the center, and form ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
