Active Field Theory Approach to Explain Size Control of Transcriptional Condensates

Macromolecular Bioscience, Volume 26, Issue 10, October 2026.
Transcriptional condensates are highly dynamic but resist coarsening in living cells, and high‐resolution microscopy reveals an exponential size distribution in steady state. This size control might be related to reverse Ostwald ripening, a genuine non‐equilibrium mechanism that arrests coarsening.

Pre‐Eruptive Volatiles and Magma Storage Depth for the 2018 Eruption at Mount Veniaminof, Alaska

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Mount Veniaminof is a frequently active, open‐system arc volcano on the Alaska Peninsula, part of the Alaska‐Aleutian arc. Mount Veniaminof's September–December 2018 eruption began with small lava flows and culminated in a larger explosive event in November that produced a 450 km long continuous ash plume—one of the volcano's most significant ...

A Late Cretaceous‐Eocene Geomagnetic Polarity Time Scale (MM26) That Combines Marine Magnetic Anomaly Records, Radioisotopic Dates, and Astrochronology

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Geomagnetic Polarity Time Scale (GPTS) is essential to date geological events in stratigraphic sequences and to reconstruct plate motions. The first GPTSs were based on the record of magnetic anomalies created by seafloor spreading, calibrated by a few radioisotopic dates.

Mapping the Western Jezero Crater Rim From Orbit: Connections to Regional Geologic Units and Context for Exploration by the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 rover is currently traversing the western rim of Jezero, a Middle to Late Noachian‐aged crater formed by an impactor that struck the northwest edge of Isidis Planitia (hereafter referred to as the Isidis basin) on Mars. Previous studies suggest that pre‐Isidis basin and Noachian outcrops are preserved throughout this region ...

Automatic Crater Classification Using a Deep‐Learning‐Based Pipeline

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Identifying and classifying impact craters on Mars is crucial for understanding the planet's geological history and surface evolution. Traditional crater classification relies on manual annotation methods, which are often limited by human biases and the difficulty of interpreting geomorphological features.
