Francis Crick: A Singular Approach to Scientific Discovery.

Francis' office window (at the Salk) commanded a panorama of the Pacific. "This grand natural scene was a physical correlate of Francis's intellectual world: wide-ranging, brilliantly lit, a little overawing, but also immensely inviting and above all an exciting place to be." (Mitchison, 2004).

The people behind the papers - Jason Ko and Daniel Lobo.

Planarians grow when they are fed and shrink during periods of starvation. However, it is unclear how they maintain appropriate body proportions as their size changes. A new paper in Development investigates the differences between growth and shrinkage dynamics and builds a mathematical model to explore the mechanisms underpinning these two processes. To learn more about the story behind the paper, we caught up with first author, Jason Ko, and corresponding author, Daniel Lobo, Associate Professor at the University of Maryland.

Transitions in development - an interview with Thibaut Brunet.

Thibaut Brunet is a group leader at the Institut Pasteur in Paris, France, where he works on choanoflagellates (known as 'choanos' for short). These unicellular organisms are close relatives of animals that have the potential to form multicellular assemblies under certain conditions, and Thibaut's lab are leveraging them to gain insights into how animal morphogenesis evolved. We met with Thibaut over Zoom to discuss his career path so far, and learnt how an early interest in dinosaurs contributed to his life-long fascination with evolutionary biology.

Pathway to Independence - an interview with Eirini Maniou.

Eirini Maniou completed her undergraduate degree at the University of Patras, Greece, before moving to the UK to complete a Master's at the University of Bath and a PhD at the University of Dundee. For her postdoctoral work at University College London, Eirini turned her attention to neural tube morphogenesis, and she is now employing engineering principles to explore this developmental process at the University of Padua, Italy, where she is a Marie Sklodowska-Curie Actions postdoctoral fellow. Eirini was selected as one of our 2024 PI fellows, a group of researchers who will be supported by Development's Pathway to Independence Programme as they aim to secure independent positions. We spoke to Eirini to hear more about her career so far, why she decided to apply to the programme and what research questions she would like to address with her own group.

Clémentine Villeneuve is a Postdoctoral Researcher at the Max Planck Institute for Molecular Biomedicine, Germany, where her research focuses on the role of mechanobiology in driving stem cell fate specification and tissue patterning during development. Clémentine is one of the fellows of Development's Pathway to Independence Programme, and we caught up with her over Zoom to find out more about her research background, her hopes for the programme and her future research questions.

Human developmental biology - a global perspective.

In the companion Perspective 'Past and future of human developmental biology' (Hopwood, 2024), historian Nick Hopwood proposes that the field of human developmental biology has gone through periods of attention and neglect. Development invited researchers from the field to respond to this idea. In this article, published to coincide with the 10th anniversary of Development's 'From Stem Cells to Human Development' meeting, researchers from eight countries comment on how they believe their local legal, political, regulatory, societal and technological frameworks are influencing the field's trajectory.

Karen is a Guest Editor for Development's Special Issue on Uncovering Developmental Diversity, which highlights how unconventional model organisms are advancing our understanding of developmental biology. We caught up with Karen to find out more about her research, the importance of public engagement and the challenges of working with unusual organisms in the lab.

The people behind the papers - Bridget Ostrem, Nuria Domínguez-Iturza and Paola Arlotta.

Maternal immune activation can affect the development of embryos, but the underlying mechanisms have been unclear. In a new study, Bridget Ostrem and colleagues show that embryonic microglia detect maternal inflammation, resulting in transcriptional changes in neighbouring brain-cell types. To find out more about the behind the paper story, we caught up with the first authors, Bridget Ostrem and Nuria Domínguez-Iturza, and corresponding author Paola Arlotta, Chair of the Department of Stem Cell and Regenerative Biology at Harvard University, USA.

The people behind the papers - Paul Huber and Carole LaBonne.

The bromodomain and extra-terminal (BET) family of proteins reads epigenetic histone acetylation marks on the genome and regulates the transcriptional machinery. In their study, Carole LaBonne and colleagues reveal the role of BET protein activity in the maintenance of pluripotency and establishment of the neural crest in Xenopus laevis. To know more about their work, we spoke to the first author Paul Huber and the corresponding author Carole LaBonne, Developmental and Stem Cell Biologist at Northwestern University.

Pathway to Independence - an interview with Keaton Schuster.

Keaton Schuster completed his PhD in the lab of Rachel Smith-Bolton at the University of Illinois, USA, investigating Drosophila wing disc regeneration before joining Lionel Christiaen's lab at New York University, USA, for his postdoc studying heart regeneration in the chordate tunicate Ciona robusta (formerly Ciona intestinalis type A). Keaton is part of the second cohort of Development's Pathway to Independence Programme fellows and we spoke to him over Teams to learn more about his career to date and his future plans for starting his own group continuing to use emerging model systems to study cardiac regeneration.

An interview with Liam Dolan.

The people behind the papers - Denis Faerberg and Ilya Ruvinsky.

Male pheromones accelerate the development of hermaphrodite larvae in Caenorhabditis elegans, but the importance of this phenomenon is not well understood. A new paper in Development shows that pheromone exposure during larval stage 3 helps coordinate behaviour and development by modulating the timing of the transition to larval stage 4. To learn more about the story behind the paper, we caught up with first author Denis Faerberg who carried out the work in the lab of the corresponding author Ilya Ruvinsky at Northwestern University, USA.

The people behind the papers - J. Guillermo Sanchez and Jim Wells.

During development, the gastrointestinal tract undergoes patterning along its anterior-posterior axis to define regions with distinct organs and functions. A new paper in Development derives human intestinal organoids from an individual with duodenal defects and a compound heterozygous variant in the gene encoding the transcription factor RFX6. By studying these organoids, the authors identify novel roles for RFX6 in intestinal patterning. To learn more about the story behind the paper, we caught up with first author J. Guillermo Sanchez and corresponding author Jim Wells, an endowed professor in the Division of Developmental Biology at Cincinnati Children's Hospital, USA, where he is also the Director for Basic Research in the Division of Endocrinology.

The people behind the papers - Yongjun Yin and David Ornitz.

During alveologenesis, multiple mesenchymal cell types play crucial roles in maximising the lung surface area. In their study, David Ornitz and colleagues define the repertoire of lung fibroblasts, with a particular focus on alveolar myofibroblasts. To know more about their work, we spoke to the first author, Yongjun Yin, and the corresponding author, David Ornitz, Alumni Endowed Professor at the Department of Developmental Biology, Washington University School of Medicine, St. Louis.

The people behind the papers - Tiffany Roach and Kari Lenhart.

Germ stem cells in Drosophila reside within a specialized stem cell niche, but the effects of stress on these stem cell populations have been elusive. In a new study, Roach and Lenhart show that repeated mating stress induces reversible changes in the germ stem cell niche. To know more about their work, we spoke to first author, Tiffany Roach, and corresponding author, Kari Lenhart, Principal Investigator at Drexel University in Philadelphia, USA.

The people behind the papers - Douglas Terry and Kenneth Moberg.

The steroid hormone ecdysone (Ec) is secreted from the prothoracic gland for growth in the developing Drosophila larva. How Ec-dependent regeneration can occur despite a drop in circulating Ec in the injured developing larvae remains unclear. In a new study in Development, Kenneth Moberg and colleagues find that injury induces local Ec synthesis at the wounded site to delay development and promote tissue repair in Drosophila. To learn more about the story behind the paper, we caught up with first author Douglas Terry and corresponding author Kenneth Moberg, Professor of Cell Biology at Emory University School of Medicine, USA.

The people behind the papers - Sangeeta Ghuwalewala, David Shalloway and Tudorita (Doina) Tumbar.

Skin renewal is characterised by progenitor cells at the epidermal basal layer dividing and differentiating, yet the identity and properties of these progenitors remain poorly understood. In a new study, Tudorita Tumbar and colleagues identify, for the first time in vivo in the mouse epidermis, a distinct population of non-self-renewing progenitor cells that exhibit biphasic transit-amplifying behaviour. To find out more about the story behind the paper, we caught up with first author Sangeeta Ghuwalewala, penultimate author David Shalloway and corresponding author Tudorita (Doina) Tumbar, Professor of Molecular Biology and Genetics at Cornell University, USA.

The people behind the papers - James O'Sullivan and Zoë Mann.

To build a functional inner ear, hair cell morphology must be precisely controlled along the proximo-distal axis. A new paper in Development shows that differential mitochondrial dynamics in proximal versus distal cells impacts on the apical cell surface area - a key aspect of morphology. To find out more about this work, we spoke to first author James O'Sullivan and senior author Zoë Mann, both at King's College London, UK.
