Radio Astronomy with NASA’s Deep Space Network

Galaxies
The Deep Space Network (DSN) is the spacecraft tracking and communication infrastructure for NASA’s deep space missions. At three sites, approximately equally separated in (terrestrial) longitude, there are multiple radio antennas outfitted with ...

A bacterial protein inhibitor of dUTPase disrupts zebrafish embryogenesis through a conserved active‐site mechanism

Protein Science, Volume 35, Issue 10, October 2026.
Abstract Deoxyuridine triphosphatase (dUTPase) is essential for DNA replication fidelity and embryonic development in metazoa, yet whether a protein inhibitor can acutely disrupt dUTPase function in a living vertebrate has not been tested. The Staphylococcus aureus Stl protein inhibits diverse dUTPases in vitro, but its efficacy in a eukaryotic ...

Prospects for the Detection of the Sgr A* Photon Ring with Next-generation Event Horizon Telescope Polarimetry

The Astrophysical Journal Letters
The Event Horizon Telescope (EHT) has imaged two supermassive black holes, Messier 87* (M87*) and Sagittarius A* (Sgr A*), using very-long-baseline interferometry (VLBI).

Typhoon‐Driven Near‐Surface Groundwater Dynamics Revealed by Ambient Noise in the Mountain Watershed

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Near‐surface groundwater dynamics (NSGD) regulate water residence time and downstream water resources in mountain watersheds, yet whether a single extreme rainfall event can reorganize near‐surface storage remains unclear. Here, we examine typhoon‐driven NSGD using ambient seismic noise from four stations, together with hydrological and ...

Effects of Side Bileaders on Parent Positive Leader

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Side bileaders are commonly induced near a progressing positive leader, yet their effects on the parent positive leader remain poorly understood. Here we investigate their effects by combining high‐speed video with LF/VLF lightning channel mapping.

First Empirical Assessment of Ice Content From a Himalayan Rock Glacier

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Climate warming and degradation of glaciers and permafrost in High Mountain Asia is threatening the sustainability of the region's natural “water towers” and allied ecosystems and infrastructure. Approximately 25,000 Himalayan rock glaciers exist and, being more resilient to climatic change than glaciers, they represent important freshwater ...

Predictions on the Abundance of Primordial Black Holes: Results from the SMILE VLBI Milli-lensing Sample

The Astrophysical Journal
Primordial black holes (PBHs) formed in the early Universe represent a well-motivated dark matter candidate. However, their abundance in the intermediate-to-high mass range (10 ^6 –10 ^9 M _⊙ ) remains relatively less constrained.

Cysteine Redox State Governs the Condensation Pathway of Hendra Virus W Protein and Differentially Impacts Type I IFN and NF‐κB Signaling

Advanced Science, Volume 13, Issue 52, 18 September 2026.
The cysteine redox state of the Hendra virus W (WHeV) protein controls assembly into fibrils or amorphous aggregates, with residues 2–29 required for fibrillation. In cells, WHeV forms different types of nuclear condensates. Impaired ability to form redox‐sensitive, non‐filamentous condensates reduces WHeV inhibition of the NF‐κB pathway, while it ...
