Residual eDNA in eRNA Extracts Skews eRNA‐Based Biodiversity Assessment: Call for Optimised DNase Treatment

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT Environmental RNA (eRNA) metabarcoding has rapidly emerged as a powerful tool for assessing contemporary biodiversity patterns across diverse ecosystems. However, the potential for false positive detections caused by co‐extracted environmental DNA (eDNA) remains unquantified.

The Truncated Lindley Distribution with Applications in Astrophysics

Galaxies, 2019
This paper reviews the Lindley distribution and then introduces the scale and the double truncation. The unknown parameters of the truncated Lindley distribution are evaluated with the maximum likelihood estimators.

Deciphering the Transcriptomic Signatures of Aging Across Organs in Mice

Aging Cell, Volume 25, Issue 2, February 2026.
Comprehensive transcriptomic profiling of eight mouse organs across six ages reveals how aging reshapes biological processes. Trajectory and network analyses distinguish shared and organ‐specific signatures, charting the molecular landscape of systemic aging.

Probing the Dark Matter and Gas Fraction in Relaxed Galaxy Groups with X-ray observations from Chandra and XMM

, 2007
We present radial mass profiles within 0.3 r_vir for 16 relaxed galaxy groups-poor clusters (kT range 1-3 keV) selected for optimal mass constraints from the Chandra and XMM data archives.

Identification of key gut microbiota and microbial QTL in contributing to the significant differences in body weight between two Chinese local chicken breeds

Animal Genetics, Volume 57, Issue 1, February 2026.
Abstract Previous studies have identified genetic loci that are associated with both feed conversion efficiency and gut microbiota in chickens, suggesting that interactions between the host genome and gut microbiota may influence chicken growth. However, the number of microbial QTL and gut microbiota associated with chicken body weight remains largely ...

Tracing the mass profiles of galaxy clusters with member galaxies

, 2005
The mass distribution of galaxy clusters can be determined from the study of the projected phase-space distribution of cluster galaxies. The main advantage of this method as compared to others, is that it allows determination of cluster mass profiles out

Improved taxonomic and gene sampling advance the knowledge of deep relationships within Macrodasyida (Gastrotricha)

Cladistics, Volume 42, Issue 1, Page 25-45, February 2026.
Abstract Advances in Macrodasyida (Gastrotricha) phylogenetics, fuelled by new species discoveries and molecular data, are reshaping taxonomic classifications. Molecular analyses suggest polyphyly in Cephalodasyidae and Macrodasyidae, yet insufficient sampling continues to obscure precise relationships.

DETERMINATION OF DARK MATTER TYPE BY X-RAY SOURCES STATISTICS

Odessa Astronomical Publications, 2014
The current cosmological model includes cold dark matter, which consists of massive nonrelativistic particles. There are also some observational and theoretical evidences for warm dark matter.

Suzaku Observations of the X-ray Brightest Fossil Group ESO 3060170

, 2013
"Fossil" galaxy groups, each dominated by a relatively isolated giant elliptical galaxy, have many properties intermediate between groups and clusters of galaxies.
