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 ...

The Earth's Greatest Porous Media

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Identification of subsurface cavities in urban environment

Scientific Reports
Gravimetry is the most suitable geophysical method for identifying subsurface cavities in urban or industrial environments, as it is unaffected by nearby electromagnetic disturbances.

Hard X-ray and Soft Gamma Ray Polarimetry with CdTe/CZT Spectro-Imager

Galaxies, 2018
CdTe/CZT based spectroscopic two-dimensional (2D)/three-dimensional (3D) imagers when operated in the Compton regime can work as high performance scattering polarimeters, for high-energy astrophysics.

Recognizing Our Role in Reframing Disaster and Emergency Management Terminology to Enhance Human Agency and Responsibility

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract This work addresses the critical issue of science literacy and science communication for scientists, researchers, officials, organizations, and the general public. Effective communication and trust between these groups are essential, particularly as the severity and scope of disasters continue to increase.

An atomic clock synchronized versatile all-in-one digital ‘LockBox’

Scientific Reports
A reliable and robust active stabilization of different control parameters is key to the success of many experiments. The essential hardware for that; lock-in detection, RF generator, and proportional-integral-derivative feedback control should have ...

A Field Guide to Corralling the Chaos: A Planning Framework for Using Models to Guide Opportunistic Field Studies of Natural Disturbances

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Watersheds regulate biogeochemical processes and provide ecosystem services to human societies, but disturbances can fundamentally alter these processes across space and time. Determining when and where to sample to capture disturbance impacts in watersheds remains a central challenge.

The Role of Ground-Based Robotic Observatories in Satellite Projects

Advances in Astronomy, 2010
We discuss the role of robotic telescopes in satellite projects, as well as related strategies. Most satellite projects in space astrophysics focus on high-energy astrophysics from X-rays to gamma-rays.

Why Are Physics‐Based Models Taking so Long to Run?

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Physics‐based models provide a reliable and interpretable framework based on established physical laws, allowing them to deal with unforeseen future conditions much better than statistical data‐driven methods. Physics‐based models in Earth science (e.g., climate models, hydrological models, and groundwater models) are commonly used for ...

Einstein and Rastall theories of gravitation in comparison

European Physical Journal C: Particles and Fields, 2018
We profit by a recent paper of Visser claiming that Rastall gravity is equivalent to Einstein gravity to compare the two gravitational theories in a general way. Our conclusions are different from Visser’s ones.
