An Extremely Active Repeating Fast Radio Burst Source in a Likely Nonmagneto-ionic Environment

The Astrophysical Journal
Fast radio bursts (FRBs) are bright radio bursts originating at cosmological distances. Only three repeating FRBs FRB 20121102A, FRB 20190520B, and FRB 20201124A among ∼60 known repeating FRBs have circular polarization.

Occultation analysis of BATSE data: Operational aspects [PDF]

The Burst and Transient Source Experiment (BATSE) large area detectors are being used to monitor hard x-ray/gamma ray sources on a daily basis for evidence of transient behavior. Flux measurements are performed using a simple earth occultation technique.

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

A Comprehensive Study of the Energy and Redshift Distributions of the Fast Radio Burst Population Based on the First CHIME/FRB Catalog

The Astrophysical Journal
Fast radio bursts (FRBs) are brief, high-energy bursts of radio waves from extragalactic sources, and their origin remains an open question. In this paper, we perform a comprehensive analysis of the FRB population using the first CHIME/FRB catalog ...

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Modeling Current and Future High-cadence Surveys of Repeating Fast Radio Burst Populations

The Astrophysical Journal
In recent years, the Canadian Hydrogen Intensity Mapping Experiment (CHIME) interferometer has revealed a large number of fast radio bursts (FRBs), including a sizable population that demonstrates repeating behavior.

Precession in transient X-ray sources [PDF]

Nature, 1975
THE origin of both the relatively long period and the transient nature of the recently discovered X-ray sources Ariel 1118−61 (ref. 1) and Ariel 0535+26 (ref. 2), with pulse periods of about 405 and 104 s, respectively, and decay times of days, is unclear. The pulse rate of A1118−61 has been attributed to an extremely short binary star orbital period3,

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

Molecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Radio Observations Point to a Moderately Relativistic Outflow in the Fast X-Ray Transient EP241021a

The Astrophysical Journal
Fast X-ray transients (FXRTs) are short-lived X-ray outbursts with diverse progenitor scenarios, including compact object mergers, stellar core collapses, and tidal disruption events.
