The image above captures a snapshot of the components of male reproductive system in Drosophila midway through their pupal development, from the paper by Jaya Kumari and Pradip Sinha. The paired testes are at the top (marked by En, red), which connect to paired seminal vesicles SV (GFP, green), opening into a central unpaired ejaculatory duct ED (GFP, green). Male Accessory Gland (MAG; GFP, green) is seen as two flap-like horizontal tubes that connect to the ED. In adults, SV and MAG periodically empty their contents, sperms and seminal fluid, respectively, into the ED. In this issue, Kumari and Sinha examine if developmental design of MAG parallels those of their mammalian counterpart, the prostate.

Motion: enhancing signals and concealing cues
Summary: While motion can reveal information about the signaller, motion can also be a means of concealing cues by reducing the likelihood of detection or the likelihood of capture following detection.
Research culture: science from bench to society
Summary: With this manuscript, we aim to increase the awareness on research culture, and illustrate that a well developed research culture can positively influence scientific developments.
Chk2-p53 and JNK in irradiation-induced cell death of hematopoietic progenitors and differentiated cells in Drosophila larval lymph gland
Summary: Irradiation-induced cell death in larval lymph gland requires Drosophila ATM, Chk2, p53, and reaper in hematopoietic progenitors, while it involves Drosophila ATM, JNK, and reaper in differentiated blood cells.
20-hydroxyecdysone (20E) signaling regulates amnioserosa morphogenesis during Drosophila dorsal closure: EcR modulates gene expression in a complex with the AP-1 subunit, Jun
Summary: During Drosophila dorsal closure, 20E signaling acts non-canonically through an interaction between EcR and the AP-1 subunit, Jun, to control gene expression at regions containing AP-1 motifs but no EcREs.
Developmental expression patterns of toolkit genes in male accessory gland of Drosophila parallels those of mammalian prostate
Summary: We show genetic toolkit conservation between Drosophila MAG and mammalian prostate may suggest a common modular developmental design.
A mouse model displays host and bacterial strain differences in Aerococcus urinae urinary tract infection
Summary:Aerococcus urinae clinical isolates are genetically diverse and display differential capacity to cause UTI in a mouse model. Infection was rapidly cleared from the bladder, but persisted and caused inflammation in the kidney.
Twitchy, the Drosophila orthologue of the ciliary gating protein FBF1/dyf-19, is required for coordinated locomotion and male fertility
Summary: Primary cilia are compartmentalised from the rest of the cell by a molecular gate. We show that the Drosophila orthologue of a molecular gate protein functions in both compartmentalised sensory cilia and ‘cytosolic’ sperm flagella.
Short-range homing in camels: displacement experiments
Summary: The study reports a series of experiments aimed at understanding the orientation mechanisms of Arabian camels in the Rub' al Khali desert in the UAE. Camels were taken either on foot or inside trucks to unfamiliar release points, some 6 km from their living pens. Camels homed successfully after simple displacements but seemed lost after a looping journey. It is inferred that camels use path integration, dead reckoning, after short simple displacements.
Energetics of whiskered bats in comparison to other bats of the family Vespertilionidae
Summary: The present study provides increased understanding of the energetic costs faced by bats in thermally challenging environments along an environmental temperature gradient.
METHODS & TECHNIQUES
Targeted mass spectrometry for monitoring of neural differentiation
Summary: We developed an adaptable mass spectrometry-based assay to assess the differentiation potential of human neural stem cells.
A Year at the Forefront of...
BiO’s new ‘A Year at the Forefront of…’ series of Review articles by early-career reseearchers aims to highlight key developments that have made an impact in a specific biological field during the past year. Read more and propose a Review here.
Propose a new Workshop for 2025
Application deadline: 30 June 2023 Do you have an idea for a Workshop? We are now accepting proposals for our 2025 Biologists Workshops programme. As the scientific organiser, your involvement will be focused on the science. We'll take care of all the logistics. In 2025 we'll continue our efforts to diversify our Workshop programme and will be reserving one of our Workshops for an application from a Global South (GS) country to host an event overseas.
Resources for early-career researchers
BiO and our publisher The Company of Biologists offer a number of practical ways to help you meet the unique needs and challenges you may encounter as an early-career researcher (ECR). Visit our dedicated ECR webpage to find out more.
Have a paper that has been reviewed elsewhere? BiO is pleased to consider such manuscripts for fast-tracked decision making. Send us your manuscript together with the full set of reviews and decision letters, and we will make an initial decision in one week (or less).
Future Leader Reviews
BiO’s Future Leader Reviews help early-career researchers:
- Establish themselves in their field
- Find a foothold in a new area after a subject change post-PhD/postdoc
- Build their profile for grant, fellowship and job applications
