A New X-Ray Census of Rotation Powered Pulsars

The Astrophysical Journal
To date, over 4000 pulsars have been detected. In this study, we identify 231 X-ray counterparts of Australia Telescope National Facility (ATNF) pulsars by performing a spatial cross match across the Chandra, XMM-Newton observational catalogs.

Reciprocal transport of carbon and nitrogen between plants and the hyphosphere microbiome in a temperate grassland

New Phytologist, Volume 252, Issue 4, Page 1602-1619, November 2026.
Overview of the experimental design and 13CO2 pulse‐labeling approach in the field. Summary Despite its relevance for plant nutrient acquisition, the role of the hyphosphere in structuring fungal–bacterial networks and mediating carbon–nitrogen (C–N) exchange under field conditions remains unclear.

Searching for Gravitational-Wave Bursts from Cosmic String Cusps with the Parkes Pulsar Timing Array’s Third Data Release

Universe
Pulsar timing arrays (PTAs) are designed to detect nanohertz-frequency gravitational waves (GWs). Since GWs are anticipated from cosmic strings, PTAs offer a viable approach to testing their existence.

Ets2 Is an Activity‐Dependent Transcriptional Regulator of a Fast‐Twitch Muscle Program

The FASEB Journal, Volume 40, Issue 20, 31 October 2026.
Ets2 is a transcription factor rapidly (24 h) upregulated in skeletal muscle by fast 150 Hz, but not slow 20 Hz, stimulation patterns. Ets2 selectively translocates to nuclei of slow soleus muscle when stimulated by fast‐patterned, but not slow‐patterned, activity. Ets2 binds to a consensus DNA sequence in the troponin I fast intronic enhancer (TnIFIRE)

CIRA-Pulsars-and-Transients-Group/vcstools: Improved Profile Fitting

, 2021
Improvements: Updated how the on-pulse region is determined for profile fitting. This means we can more accurately estimate the S/N. Implemented an exponential-convolved gaussian for fitting so that scattered profiles can be fit more effectively. Added

Tumor‐Regional Immune Microenvironment: A Critical Factor in the Design of Radiotherapy–Immunotherapy Combination Trials

International Journal of Cancer, Volume 159, Issue 8, Page 1857-1872, 15 October 2026.
ABSTRACT Clinical trials combining radiotherapy (RT) with immune checkpoint blockade (ICB) have shown improved outcomes in only a fraction of patients, and optimal strategies for integrating these modalities remain under intense investigation. With a few exceptions, phase III combination trials have yielded disappointing results.

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, Volume 12, Issue 20, 26 October 2026.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Gamma-Ray Pulsars [PDF]

, 2011
The Fermi Gamma-Ray Space Telescope has revolutionized the study of pulsar physics with the detection of over 80 gamma-ray pulsars. Several new populations have been discovered, including 24 radio quiet pulsars found through gamma-ray pulsations alone ...

Multi‐omics integration and machine learning identify an ACKR1+ endothelial cell‐based lactate‐immune signature associated with carotid plaque vulnerability and progression

Clinical and Translational Medicine, Volume 16, Issue 10, October 2026.
ACKR1+ endothelial cells mark intraplaque neovessels with hyperactive glycolysis and lactate metabolism. Lactate, HIF‐1α and CXCL12 link this state to CXCR4+ CD8+ T‐cell recruitment in situ. SLC16A3 and SLC16A4 serve as quantitative readouts of this lactate–immune state.
