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.

, 2007 The relevance of gamma-ray astronomy to the search for the origin of the galactic and, to a lesser extent, the ultra-high-energy cosmic rays has long been recognised. The current renaissance in the TeV gamma-ray field has resulted in a wealth of new data on galactic and extragalactic particle accelerators, and almost all the new results in this field ...

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.

Gamma Ray Astronomy with Magnetized Zevatrons
, 2005 Nearby sources of cosmic rays up to a ZeV(=10^21 eV) could be observed with a multi-messenger approach including secondary gamma-rays and neutrinos. If cosmic rays above ~10^18 eV are produced in magnetized environments such as galaxy clusters, the flux ...

Sense of Belonging in Science: A Focus on the Construct
Journal of Educational Measurement, Volume 63, Issue 2, Summer 2026.Abstract The importance of the construct to the fields of measurement and cognitive science cannot be overstated. Without an understanding of the construct, including clarity and scope of the substantive and structural aspects, one cannot ensure valid use and interpretation of a constructed measure.

High energy gamma ray astronomy [PDF]
High energy gamma ray astronomy has evolved with the space age. Nonexistent twenty-five years ago, there is now a general sketch of the gamma ray sky which should develop into a detailed picture with the results expected to be forthcoming over the next ...

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract We present a method to infer ocean diapycnal diffusivity based on high‐resolution ocean model predictions of the depth‐dependent viscous dissipation associated with internal wave shear. This method relies on recent advances in modeling and the parameterization of stratified turbulent mixing processes.
