Martian Proton Albedo as Signature of Near‐Surface Water

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

Stochastic galaxy disk evolution. 2-D models.

, 2015
Understanding of star formation processes in galaxy disks is one of the most important problems of the contemporary astrophysics. Despite fast-growing amounts of observational data, which allow studies of star formation in galaxy disks, there is a lack ...

On the Evolutionary History of a Simulated Disk Galaxy as Seen by Phylogenetic Trees

The Astrophysical Journal
Phylogenetic methods have long been used in biology and more recently have been extended to other fields—for example, linguistics and technology—to study evolutionary histories.

On the Role of Electron Precipitation in Excess Radiation Doses Measured at Aviation Altitudes

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Radiation from space in the form of galactic cosmic rays (GCRs) generates a persistent background of ionizing radiation in Earth's atmosphere. The dose rate of ionizing radiation due to GCRs increases from sea level to aviation altitudes.

Development, Characterization, and Stability of Burgers With Partial or Total Replacement of Beef by Vegetable Ingredients

Journal of Food Science, Volume 91, Issue 6, June 2026.
ABSTRACT This study evaluated the partial or total replacement of beef (0%, 25%, 50%, 75%, and 100%) with plant‐based ingredients (risotto rice, textured soy protein, and cassava starch) in burgers, combined with the incorporation of freeze‐dried açaí pulp as an antioxidant and natural colorant, and sesame oil as a substitute for beef fat.

Chemical enrichment of isolated relic galaxy Mrk1216

In this study, we investigate the chemical enrichment and structural evolution of the isolated elliptical relic galaxy Mrk1216 through X-ray observations. As a red-nugget relic, Mrk1216 provides a rare window into the early Universe, owing to its minimal

Quantifying Bursty Star Formation in Dwarf Galaxies

The Open Journal of Astrophysics
Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than ~100 Myr should lead to discontinuous
