A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

Journal of Applied Crystallography, EarlyView.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Calibrating Galaxy Infall Times in Groups and Clusters with IllustrisTNG Simulations

The Astrophysical Journal
The time since a galaxy first became a satellite is central to understanding how environment drives galaxy evolution, yet it cannot be measured directly.

Humble beginnings of the Australian giant wood moth (Endoxyla cinereus): A century‐old mystery solved

Insect Science, EarlyView.
The Australian giant wood moth (Endoxyla cinereus) feeds within the galls of scale insects (Apiomorpha) before transitioning into its wood‐boring eucalypt larval phase. This transitionary phase may be key to its multi‐year development, at the end of which it can produce over 100 000 eggs.

Discovering Large-scale Structure at 2 < z < 5 in the C3VO Survey

The Astrophysical Journal
The Charting Cluster Construction with VUDS and ORELSE (C3VO) survey is an ongoing imaging and spectroscopic campaign aiming to map out the growth of structure up to z  ∼ 5 and was born from the combination of the Visible Multi-Object Spectrograph Ultra ...

Galaxy groups within voids

Astronomy & Astrophysics
Context. Despite cosmic voids being vast and almost empty, galaxy aggregations do exist within them, although they are much sparser than in denser regions like walls, filaments, and clusters.

Effect of Salinity Stress on Gut–Brain–Gonad Axis in the Red‐Eared Slider (Trachemys scripta elegans)

Integrative Zoology, EarlyView.
The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.

In medio stat virtus: Enrichment history in poor galaxy clusters

Astronomy & Astrophysics
The enrichment history of galaxy clusters and groups remains far from being fully understood. Recent measurements in massive clusters have revealed remarkably flat iron abundance profiles out to the outskirts, suggesting that similar enrichment processes

Galaxy Populations in Groups and Clusters: Evidence for a Characteristic Stellar Mass Scale at M ∗ ∼ 109.5 M ⊙

The Astrophysical Journal, 2023
We use the DR9 of the DESI legacy imaging survey and SDSS galaxy groups to measure the conditional luminosity function (CLF) for groups with halo mass M _h ≥ 10 ^12 M _⊙ and redshift 0.01 ≤ z ≤ 0.08, down to a limiting r -band magnitude of M _r = −10 to −

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

Animal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.
