Active galaxies and cluster gas [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005
Two lines of evidence indicate that active galaxies, principally radio galaxies, have heated the diffuse hot gas in clusters. The first is the general need for additional heating to explain the steepness of the X–ray luminosity–temperature relation in clusters, the second is to solve the cooling–flow problem in cluster cores.

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.

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 ...

Stealing galaxies from galaxy clusters

Publications of the Astronomical Society of Australia
Abstract We investigate galaxy groups that reside in the field but have been previously processed by galaxy clusters. Observationally, they would appear to have the same properties as regular field groups at first glance. However, one would expect to find quantifiable differences in processed groups as dynamical interactions within clusters perturb ...

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

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.

Cluster Physics with Merging Galaxy Clusters

Frontiers in Astronomy and Space Sciences, 2016
Collisions between galaxy clusters provide a unique opportunity to study matter in a parameter space which cannot be explored in our laboratories on Earth.

Genetic Diversity of Neospora Caninum in Palestinian Cattle and Sheep: Insights From Nc-5 Gene Detection and MS10 Microsatellite Analysis. [PDF]

Vet Med Sci
N. caninum DNA was detected in 24.2% of sampled cattle and sheep brains, with a higher prevalence in cattle (25.5%) than sheep (16.7%). Palestinian isolates formed one cluster, with the ACT allele predominating (76%). Phylogenetic analysis revealed low genetic diversity in N. caninum globally.

Epidemiology and Genetics of Rheumatic Diseases Suggest a Constant Rate of DNA Damage as Underlying Cause

Immunology, EarlyView.
A constant rate of DNA damage that is not perfectly repaired will cause a constant rate of DNA mutations. The chance of mutation will increase if DNA is prone to damage, such as occurs in somatic hypermutation (SHM) hotspots and GC‐rich DNA. Thus, if one mutation‐prone DNA site drives disease, the age of onset of disease and degree of penetrance should
