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?

Black hole as coherent signal amplifier

European Physical Journal C: Particles and Fields
In a recent analysis (Misra et al. in npj Quantum Inf 10:34, 2024. 10.1038/s41534-024-00817-w), it has been shown that Hawking radiation is the main source of energy to empower a coherent signal pulse. In this work, we have explored the same effect for a

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.

Supernova remnants as particle accelerators and probes of the circumstellar medium [PDF]

, 2010
Although the night sky may look static on a regular night, apart from the rising moon and the occasional shooting star, a closer look and different timescales reveal that this is certainly not the case.

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 ...

Relativistic 56Ni decay lines in GRB 221009A

Communications Physics
Long Gamma Ray Bursts are thought to originate from the core collapse of massive stars that give rise to energetic broad-lined Type Ic supernovae. The brightest burst ever recorded, GRB 221009A, has been linked to a broad-lined Type Ic supernova through ...

Researchers' Well‐Being Through My Academic Career in Japan, Germany and USA

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Upon development of my academic career in Japan, Germany, and USA, I have increasingly recognized the importance of researchers' well‐being. While the research lifestyles in these three countries were distinct, it has been essential for me to maintain good well‐being for the sustainable development of my academic career.

Exploring the Components of Cosmogenic UHECR, Neutrino, and Diffuse Gamma Ray from High-Energy Astrophysical Objects

Galaxies
The development of multimessenger astrophysics allows us to probe various background particles from the distant early universe. Up to now, much effort has been made researching the emission and radiation of diverse steady or transient astrophysical ...
