Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

Insect Science, EarlyView.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

Characterising galaxy clusters’ completeness function in Planck [PDF]

EPJ Web of Conferences
Galaxy cluster number counts are an important probe to constrain cosmological parameters. One of the main ingredients of the analysis is the selection function, and in particular the completeness, associated to the cluster sample one is considering ...

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

Cladistics, EarlyView.
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.

JWST NIRCam Observations of the Globular Cluster Population of RXJ 2129.7+0005

The Astrophysical Journal
We present an analysis of the globular cluster (GC) population in the galaxy cluster RXJ 2129.7+0005 ( z = 0.234) based on JWST NIRCam imaging in three filters: F115W, F150W, and F200W.

Towards the first mean pressure profile estimate with the NIKA2 Sunyaev-Zeldovich Large Program [PDF]

EPJ Web of Conferences
High-resolution mapping of the hot gas in galaxy clusters is a key tool for cluster-based cosmological analyses. Taking advantage of the NIKA2 millimeter camera operated at the IRAM 30-m telescope, the NIKA2 SZ Large Program seeks to get a high ...

Winter‐active spiders (Clubiona) have a hyperactive antifreeze protein with a unique beta‐solenoid fold

The FEBS Journal, EarlyView.
Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.
