Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Random Diophantine equations in the primes

Mathematika, Volume 72, Issue 3, July 2026.
Abstract We consider equations of the form a1x1k+⋯+asxsk=0$a_{1}x_{1}^{k}+\cdots +a_{s}x_{s}^{k}=0$ where the variables xi$x_{i}$ are all taken to be primes. We define an analogue of the Hasse principle for solubility in the primes (which we call the prime Hasse principle), and prove that, whenever k⩾2$k\geqslant 2$, s⩾3k+2$s\geqslant 3k+2$, this holds

Open‐Source Multinuclear Low‐Field Preclinical MRI Scanner

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
A step‐by‐step guideline for the construction of an open‐source multinuclear low‐field MRI scanner for preclinical studies is presented together with the first images acquired with the device. The scanner can detect 1H, 23Na, hyperpolarized 13C, and 15N signals at 66 mT. ABSTRACT Low‐field MRI (B0 ≤ 0.2 T) is emerging as a technology with the potential

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Historical trends in self‐reported US heroin initiation

Addiction, Volume 121, Issue 6, Page 1611-1615, June 2026.
Abstract Background and aims Illegal opioids create challenges for public health and safety. There is imperfect understanding of when use of illegally manufactured opioids increased. This paper examined data on self‐reported year of first heroin use in the United States. Design Secondary analysis of general population survey data. Setting United States.
