A male tree cricket of the species Oecanthus henryi calling from its perch on a bush. Like other crickets, O. henryi males use acoustic signals to attract females. O. henryi males can also amplify their call by turning leaves into acoustic ‘baffles’ that amplify calls. However, not all males do this, and many males do not emit any calls at all. In their study, Sadiq et al. use simulations to study how the spatial structure of the habitat that these crickets live in can facilitate the coexistence of alternative reproductive tactics in males.

MEETING REVIEW
Neural crest development and disorders: from patient to model system and back again – the NEUcrest conference
Summary: In March 2024, the early-stage researchers in the NEUcrest consortium organised an in-person conference for well-established and early career researchers to discuss new advances in the neural crest and neurocristopathies field.
RESEARCH ARTICLES
Re-assessment of the subcellular localization of Bazooka/Par-3 in Drosophila: no evidence for localization to the nucleus and the neuromuscular junction
Summary: The authors found that Bazooka/Par-3 does not localize to the nucleus or the neuromuscular junction, questioning earlier findings reporting a function of Baz at these subcellular sites.
An arch worth revisiting: a study on the feline humeral supracondylar foramen and its evolutionary significance
Summary: The feline supracondylar foramen was investigated using micro-computed tomography, and the novel insights assigned the peripheral arch a tendinous remnant of a digressing head of the coracobrachialis longus muscle.
The Endosomal Sorting Complex, ESCRT, has diverse roles in blood progenitor maintenance, lineage choice and immune response
Summary: Components of the cargo-sorting machinery have context-dependent roles in blood progenitor maintenance and lineage choice, helping to tackle immune challenges and tailor developmental diversity.
microRNA-guided immunity against respiratory virus infection in human and mouse lung cells
Summary: Our studies showed how the differential expression of pulmonary miRNAs could contribute to respiratory virus infection and species- or tissue-specific mechanisms and common mechanisms conserved in humans and mice.
Hormonal regulation of miRNA during mammary gland development
Summary: By combining the patterns of expression of miRNA during mammary development and the miRNAs with expression shown to be regulated by hormones, we identified 16 mammary gland miRNAs whose expression is likely regulated by circulating hormones.
Single target acuity for moving targets in the common sunfish (Lepomis gibbosus)
Summary: This study reveals that the common sunfish's visual system perceives moving targets with equal precision as stationary targets.
Spatial structure could explain the maintenance of alternative reproductive tactics in tree cricket males
Summary: Trait polymorphisms are common in nature, posing an evolutionary puzzle. Studying alternative reproductive tactics in tree crickets, reveals spatial dynamics facilitate the maintenance of diverse strategies.
METHODS & TECHNIQUES
Assessing metabolic rates in zebrafish using a 3D-printed intermittent-flow respirometer and swim tunnel system
Summary: Using a 3D-printed respirometer and swim tunnel system (drawings are available) we measured standard metabolic rate and compared two different protocols for measuring maximum, aerobic metabolic rate of zebrafish.

Offering high-quality peer review through Review Commons

Did you know that BiO is an affiliate journal for Review Commons? This platform offers high-quality peer review of preprints before journal submission. This is just one of the many transfer options we offer to and from BiO. Read published articles that have come to us through this route in our Review Commons collection.
Daniel Gorelick on Open Access and Read & Publish in Biology Open
Editor-in-Chief, Daniel Gorelick, talks about Biology Open, the importance of Open Access publishing and how The Company of Biologists’ Read & Publish initiative benefits researchers.
Phosphorylation of α-catenin helps cells stick together during mitosis

In this Research Article, Phuong Le, Jeanne Quinn and colleagues found that the adhesion protein α-catenin has a key modification that allows dividing cells to stay better connected to their neighbours, helping the tissue stick together during mechanical stress.
How we support early-career researchers

Biology Open, its sister journals and its not-for-profit publisher, The Company of Biologists, support early-career researchers in numerous ways, helping them grow their network and raise their profile. Find out what we can do to support you.
