Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

The Spectroscopic Impact of Sublimation Under Martian Surface Conditions: Implications for Sample Analysis by the Rosalind Franklin Rover and Biosignature Preservation

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The 2028 ESA/NASA Rosalind Franklin Mission (RFM) will search for signs of past and present life in the shallow subsurface of Mars. It is crucial to understand how minerals and any biosignatures uncovered during these sampling activities might change and be identified under today's Martian conditions.

Modeling Study on Energetic Particle Distribution in the Ionospheric South Atlantic Anomaly at Height of the Space Station

Space Weather, Volume 24, Issue 4, April 2026.
Abstract The South Atlantic Anomaly (SAA) in Earth's radiation belt is a critical region that poses significant threats to the safety of Space Stations. This region harbors a high concentration of energetic particles that can penetrate Space Stations, thereby affecting onboard components and posing risks to astronauts.

Epidemiology and Genetics of Rheumatic Diseases Suggest a Constant Rate of DNA Damage as Underlying Cause

Immunology, Volume 177, Issue 4, Page 736-748, April 2026.
A constant rate of DNA damage that is not perfectly repaired will cause a constant rate of DNA mutations. The chance of mutation will increase if DNA is prone to damage, such as occurs in somatic hypermutation (SHM) hotspots and GC‐rich DNA. Thus, if one mutation‐prone DNA site drives disease, the age of onset of disease and degree of penetrance should

Understanding Impact of Anti‐Obesity Medications on Skeletal Muscle Mass Change Is Confounded by Measurement Methods

Obesity Reviews, Volume 27, Issue 4, April 2026.
ABSTRACT Anti‐obesity medications promote greater degrees of weight loss than lifestyle interventions alone. There is an important need to understand whether loss of skeletal muscle during pharmacologically induced weight loss is clinically significant due to its essential role in health and disease.

Simultaneous Formation of Arsenic Nitride Chalcogenides As3NS3 and As3NSe3 and Arsenic–Chalcogen Zintl Anions by Ammonothermal Reactions

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 5, 18 March 2026.
Mn, As, and S or Se react in liquid NH3 to the Zintl ions (As4S6)2– and (As2Se6)2–. Simultaneously, the arsenic nitride chalcogenides As3NS3 and As3NSe3 are formed. Their isotypic structures contain planar trigonal NAs3 groups connected via chalcogen bridges to 1D‐strands forming channels that can host solvent molecules.
