Fantastic academic jobs and how to find them 🪄

Posted by , on 10 October 2024

At preLights, the preprint highlighting service run by early-career researchers, we recently launched ‘spotLights’: a podcast series where we delve deeper into exciting preprints, featuring interviews with the scientists behind the research. These conversations allow you to hear the stories, challenges, and motivations that go into producing impactful scientific work. All episodes so far can be found here.

In episode three of spotLights, we explore a topic that’s highly relevant for early-career researchers: An updated and expanded characterization of the biological sciences academic job market. If you’re on the academic job hunt or thinking about your next steps in academia, this episode is full of valuable insights!

It goes beyond the accompanying preLight post that describes the key findings. You’ll get the chance to hear from two of the preprint authors, Dr Nafisa Jadavji and Dr Chris Smith, who share the background, process, and motivations behind their study. Don’t miss out on this insightful discussion! Tune in now and get the inside scoop directly from the experts.

Note: spotLights episodes 1 and 2 both revolve around preprinted work that describes the cephalic furrow as a “crumble zone” between head and trunk tissues (see related preLight post). Episode 1 features Bruno Vellutini, the first author of the preprint “Patterned embryonic invagination evolved in response to mechanical instability.” Episode 2 highlights the work led by Bipasha Dey, Verena Kaul, and Girish Kale, resulting in the preprint “Divergent evolutionary strategies preempt tissue collision in fly gastrulation.”

Counterpoint in Science: Power of Tandem talks at the Interfaces between Physics and Biology

Posted by , on 26 September 2024

HFSPUnistra Symposium available online featuring Eric Wieschaus and William Bialek, Anthony Hyman and Frank Jülicher, Donatas Zigmantas and Thomas Renger, musical duo from the Philharmonic Orchestra of Strasbourg and more

Daniel Riveline,1 Karsten Kruse,2 Mukund Thattai,3 Guntram Bauer4

Scientific communication was pioneered in the 17th century (Ref. 1). Scientists were called ‘sçavans’ and had to embrace the humanities and the sciences to present their discoveries with clarity. These achievements are difficult nowadays, with the detailed technical knowledge involved in biology, physics, chemistry and mathematics research. In this context, it is challenging to present the depth of each side of an interdisciplinary scientific question, and often one field is featured more prominently, to the detriment of the other. To address this issue, we organised a Symposium in which presentations were given as tandem talks, with participants from biology and physics or from chemistry and biology. Topics ranged from cell positioning in the embryo (Eric Wieschaus and William Bialek), to liquid condensates (Anthony Hyman and Frank Jülicher), to the physics of photosynthesis (Donatas Zigmantas and Thomas Renger). We found this tandem format to be extremely successful (see Symposium online Ref. 2). Concepts from physics, biology and chemistry were explained in accessible yet informative language, and the audience could see how interdisciplinary engagements developed. Importantly, the speakers highlighted active points of debate and articulated unresolved issues, leaving space for new breakthroughs and scientific directions. As a metaphor for collaboration, a musical duo on the violin and cello illustrated how each voice in a partnership could be heard. Using a Bach counterpoint as the paradigm, the musicians from the Philharmonic Orchestra of Strasbourg explained how their pieces were harmonious only with shared and alternating voices.

Bringing Science to Life: IDRM at Oxford Open Doors

Posted by , on 26 September 2024

Oxford Open Doors is an annual event that offers the public a unique opportunity to explore the historic and modern buildings of Oxford, many of which are normally closed to the public. Organized by Oxford Preservation Trust, the event takes place over a weekend in September and allows visitors to experience the architectural and cultural heritage of the city first hand.

As part of this year’s Oxford Open Doors event, researchers from the Institute for Developmental and Regenerative Medicine (IDRM) invited the public into their labs, offering a rare glimpse into their cutting-edge research. Visitors were guided through research areas and imaging facilities by enthusiastic staff eager to share their work.

The IDRM is a unique flagship institution at the University of Oxford, dedicated to meeting an ambitious challenge: two thirds of all deaths world-wide are due to non-communicable diseases, many of which are cardiovascular, neurological or immune system disorders that have a developmental origin, representing an urgent unmet clinical need.  The mission of the IDRM is the development of new drugs and therapeutic strategies to tackle these chronic illnesses.

At its core is a formal merger of developmental biology and regenerative medicine in the form of over 200 cardiovascular, neuroscience and immunology scientists, integrating their expertise to foster multidisciplinary collaborations. 

Under this research interest, we’ve developed a number of initiatives for Public Engagement that we deployed at this Open Day: the first, Synchrony, is a unique science-art project created in collaboration with computational artist Andy Lomas. Part of the public engagement efforts of the Wellcome funded Human Developmental Biology Initiative, Synchrony brings the complex world of developmental biology to life.

Synchrony allowed attendees to interact with a 3D artificial simulation of growth and pattern formation, changing the rules that govern the formation of some of the fascinating shapes that we can observe during embryonic development. This immersive experience captured visitors’ curiosity and sparked conversations about the intricate biological processes that direct embryo development and organ formation with Matthew Stower who represented the HDBI researchers. The creative process itself involved lengthy discussions between Andy and researchers Matthew Stower, Shifaan Thowfeequ, Claudio Cortes, Tomoko Watanabe and Shankar Srinivas.

In addition to Synchrony, visitors also engaged with scientific discovery through SyGlass, a virtual reality software for exploring, annotating and sharing 3D data. SyGlass allows users to fully immerse themselves in stunning microscopy images, rendered in interactive 3D in a VR environment. A breath-taking image of the embryonic thymus, contributed by David Grainger, enabled attendees to explore the beauty and intricacies of the 3D structure of this organ. Both children and adults delighted in slicing through the tissue sections and navigating the complexities of the thymus in real time.

We would like to thank The Node for their support. Your extremely popular postcards gave us the perfect ‘hook’, to talk about the wonders of development and how it takes place across species. These visuals helped visitors connect the beauty and complexity of developmental biology with the cutting-edge research happening within IDRM, while at the same time sparking very interesting conversations about research and ethics.

“Environmental Cues for Life Cycle Transitions” symposium – a perspective from EuroEvoDevo 2024

Posted by , on 25 September 2024

Núria Ros-Rocher1, Júlia Ramon Mateu2, Elizabeth Williams3

1 Institut Pasteur, Université Paris-Cité, CNRS UMR3691, Evolutionary Cell Biology and Evolution of Morphogenesis Unit, 25-28 Rue du Dr. Roux, 75015 Paris (France)

2 Laboratoire de Biologie du Développement de Villefranche-sur-mer (LBDV), UMR7009 CNRS/UPMC, Institut de la mer de Villefranche, Quai de la Darse, 06234 Villefranche-sur-Mer Cedex, France

3 University of Exeter Biosciences, Streatham Campus, Stocker Rd, Exeter EX4 4QD, UK

With some beautifully warm and sunny mid-summer weather, attendees of the EuroEvoDevo2024 gathered on Friday morning 28th June at the University of Helsinki for a symposium on ‘Environmental cues for life cycle transitions’. This was one of twenty-four symposia at this year’s meeting, with a record attendance of over 600 people. It was co-organized by Vincent Laudet (Okinawa Institute of Science and Technology, Japan and Academia Sinica, Taiwan) and Elizabeth Williams (University of Exeter, UK) and involved ten presenters. This symposium aimed to examine life cycle transitions and the influence of the environment on them from a broad perspective across organisms from different kingdoms of life. What aspects of the environment trigger changes in an organism’s form and physiology and how do organisms sense these?

Although starting early on the final morning of the conference, our enthusiastic late-night discussions at the nearby conference pub, the ‘Thirsty Scholar’, were offset by strong Finnish coffee, a selection of fresh vegetarian foods, the promise of the conference dinner and party later that evening, and our shared interest in the evolution of complex life cycles. The symposium brought together diverse researchers and topics, with study organisms ranging from liverwort to diatoms, choanoflagellates, insects, marine invertebrates, and fish. Environmental cues discussed ranged from abiotic factors such as light, temperature and salinity, to biotic cues including microbial biofilms, coralline algae, and food type and availability.    

The symposium’s introductory slide included example images of the diverse organisms studied by presenters.

Overall, five different types of life cycle transition were discussed. Arild Husby, from Uppsala University (Sweden), presented recent work on morphological polyphenism in water striders, which is induced by changes in photoperiod. When exposed to more hours of light in the day, water striders will develop short-wing phenotype and under short day lengths will develop long-winged phenotypes. RNA sequencing followed by RNAi knockdown and ELISA measurements of the insect moulting hormone ecdysone indicated that this polyphenism is regulated by the Fat/Hippo pathway (Gudmunds et al. 2024), with a possible role for ecdysone signalling. The Fat/Hippo pathway controls organ size in animals and relates to a fundamental question in developmental biology: how does an organ know when to stop growing after reaching a particular size? The ecdysone signalling pathway was also the focus of work presented by Giulia Campli, from the University of Lausanne, Switzerland, who investigated the moulting gene repertoire across an impressive 153 proteome dataset, comprehensive of insect, crustacean and chelicerate arthropod species, highlighting changes and novelties in the molecular machinery driving the moulting process, a second type of life cycle transition for exoskeleton renewal (Campli et al. 2024). 

A third common type of life cycle transition among animals is metamorphosis from a larval to a juvenile form. Several speakers focused on this transition across a wide range of animals, from sponges to fish. Océane Blard, PhD student at the University of Queensland (Australia), presented remarkable brightfield timelapses and fluorescent confocal images illustrating the morphological and cellular changes observed during the first 6 hours of metamorphosis in the marine sponge Amphimedon queenslandica. She also tracked the fate of larval sensory-secretory cells, known as flask cells, which are proposed to detect cues from coralline algae to initiate settlement and metamorphosis (Nakanishi et al. 2015). These cells appear to be able to transdifferentiate, and future research will focus on understanding the molecular mechanisms underlying this process using single cell transcriptomics. Elizabeth Williams, research fellow at the University of Exeter (UK), focused on understanding how free-living larvae settle and metamorphose to become seafloor-dwelling juveniles. Elizabeth and colleagues found that microalgae biofilms, notably diatoms, induce a settlement response in the marine worm Platynereis dumerilii (Hird et al. 2024), they described similar sensory-neurosecretory cells across polychaete, cnidarian and mollusc larvae, potentially responsible for timing metamorphosis according to external environmental conditions. In future work, Elizabeth and colleagues will focus on the morphology, function and molecular signalling mechanisms of these cells.

Júlia Ramon Mateu, PhD student at the Laboratoire de Biologie du Développement (LBDV) in Villefranche-sur-mer, presented her PhD work on the cellular and molecular mechanisms of cnidarian settlement. She identified and characterized the cell types forming the aboral end (head) of the planula larva of three cnidarian species belonging to the two main clades of Cnidaria: the jellyfish Clytia hemisphaerica and the corals Astroides calycularis and Pocillopora acuta. To do so, she generated bulk RNA-seq data from the planula aboral end and single-cell RNA-seq data from the same larval stage for each species. Through a comparative analysis of transcriptomic profiles, morphology and distribution of aboral cell types between the larvae of Clytia and the two coral species, she defined the common cellular architecture of the planula aboral end featuring two broad cell-type classes: secretory-like and neural-like. Of particular interest, she identified genes related to taurine uptake and catabolism as a shared feature of specialized cells in the planula aboral end: associated with a neural cell type in Clytia and a specialized epidermal cell type in the two coral species. Using settlement assays developed for both Clytia and Astroides planulae, she could show that exogenous taurine delays or prevents settlement in both species. Júlia concluded her presentation with an updated model of the cells and molecules involved in cnidarian larval settlement, proposing taurine uptake as a key factor in the regulation of the settlement response.

Vincent Laudet (Okinawa Institute of Science & Technology, Japan and Academia Sinica, Taiwan) also investigates the environmental influences of larval metamorphosis and phenotypic disparity in coral reef fish. Like marine invertebrates, the environment can also modulate different aspects of fish metamorphosis from pelagic larvae to reef-associated juveniles. Vincent presented a case of environmental acclimation in fish populations living in the enclosed lagoon of Taiaro Atoll, an extreme environment in French Polynesia, (Reynaud et al. 2023). Compared to their natural habitat (beaches and mangroves), the lagoon displays higher salinity and temperature. Interestingly, fish living in the lagoon and their counterparts living in oceanic reefs were identical at the genetic level, despite differences in their habitat. To understand the molecular mechanisms of fish acclimation to high salinity, Vincent and colleagues compared their transcriptomic profiles and found that each population had particular differences in thyroid hormone regulation. Thyroid hormones are central hormone regulators triggering metamorphosis in vertebrates (Zwahlen et al. 2024). In fish, they regulate a major metabolic shift during metamorphosis from the juvenile to the adult phase, including changes in pigmentation and maturation of the nervous/sensory and digestive systems. Vincent and colleagues proposed a new view of the role of thyroid hormones: rather than functioning independently in metamorphosis, metabolism and seasonality, thyroid hormones perform a 3-in-1 function of timing a biphasic life cycle transition. Thus, local acclimation to the environment is an endocrine-driven process, conferring plasticity on fish from the time they undergo metamorphosis and enabling them to adapt to high salinity conditions.

Núria Ros-Rocher, postdoctoral researcher at Institute Pasteur (Paris, France), presented another case of salinity-dependent life cycle transition in a microeukaryote. Núria showed that Choanoeca flexa, a facultatively multicellular choanoflagellate (Brunet et al. 2019;Reyes-Rivera et al. 2022), develops colonies by an unconventional mixed mode of clonal-aggregative multicellularity (Ros-Rocher and Reyes-Rivera et al. 2024). To further explore the ecological determinants of C. flexa clonal-aggregative multicellularity, Núria, Josean, and colleagues combined cell biology approaches in the laboratory with fieldwork experiments in the Caribbean island of Curaçao, the original site where this species was discovered (see Brunet et al. 2019). In the field, they surveyed 150 seawater-filled splash pools, the natural habitat of C. flexa, and explored the impact of splash pool evaporation and refilling cycles on C. flexa multicellularity. C. flexa colonies could only be observed in a narrow range of salinity and were never observed in higher salinities in the field, yet sometimes appeared in splash pools that got refilled by waves or splash after complete desiccation.

Surprisingly, multicellular C. flexa colonies could be recovered from soil samples collected from dry splash pools upon rehydration with seawater in the lab. Later experiments in the lab mimicking the evaporation of splash pools showed that colonies dissociate into quiescent single cells in high salinities, losing multicellularity. In those conditions, some single cells transitioned into a desiccation-resistant form, losing some of the stereotypical choanoflagellate features (a collar and a flagellum). Repeating similar rehydration experiments, Núria showed that those cells could return to their multicellular form upon rehydration. The authors hypothesized that this mixed clonal-aggregative strategy might represent a versatile adaptation to the ephemeral nature of splash pools where the simultaneous action of both mechanisms could allow for a faster re-establishment of multicellularity. In ongoing work, Núria, Josean and colleagues are exploring the genetic diversity of newly isolated strains from distinct splash pools. They are focusing on kin recognition capacities that may impact choanoflagellate survival in the field and provide insights into the adaptation of this organism in a highly fluctuating environment.

In addition to metamorphoses and multicellularity, three presenters also discussed later-in-life transitions related to reproduction. Mariella Ferrante, researcher at the Stazione Zoologica Anton Dohrn (Italy), presented recent work on centric and pennate diatoms exploring how these different single-celled microalgae switch between sexual and asexual reproduction. While sexual reproduction in centric diatoms can be triggered by environmental cues such as light and salinity, pennate diatoms do not appear to have a specific trigger for initiating sexual reproduction. However, planktonic pennate diatoms need to solve the challenging problem of locating a mate within the vast 3D ocean to undergo sexual reproduction before they drop below a critical size due to several rounds of asexual reproduction which cause them to decrease in size with each asexual division. Mariella and colleagues are using RNA-Seq and single-cell RNA-seq in different diatom species and reproductive stages to explore heterogeneity in diatom populations as well as to identify a panel of molecular markers for detecting diatom sex events at sea (Annunziata et al. 2022).

 Alexandre Alié, researcher at the Laboratoire de Biologie du Développement (LBDV) in Villefranche-sur-Mer, is also using scRNA-Seq to understand asexual reproductive transitions in another organism that inhabits the pelagic oceans – Mediterranean salps, planktonic tunicates that form large chains through asexual reproduction. Alexandre and colleagues hope to use this information to understand more about how the stem cells in the stolons of the salps can bud off dozens of new individuals and how this process is influenced by environmental factors such as temperature and food availability. Finally, David Hoey introduced us to the molecular regulation of transformations for reproduction in the liverwort Marchantia polymorpha, which switches between sexual and asexual reproduction throughout the year depending on light quality, day length and drought conditions (Duckett et al. 2024). David generated knockout lines of a RAS gene and found that it is a regulator of asexual reproductive development in M. polymorpha. Remarkably, this gene is responsive to both light and drought cues.

Overall, a strong theme running through the symposium was the development of molecular lab techniques such as gene knockout and single-cell RNA-Seq for application in a variety of non-model organisms. Ongoing studies on all of these emerging models are advancing our understanding of how environmental cues are detected and lead to important transitions in a life cycle. We also found inspiration in the examples from several researchers of combining their molecular lab studies with field studies of their organism of interest, to place our understanding of organismal and life cycle diversity back into a broader ecological context. We anticipate that this will be a strong theme going forwards, and aligns with the emphasis on eco-evo-devo that was highlighted at this year’s conference by keynote speaker Scott Gilbert, who also drew attention to the importance of microbial ecology in shaping animal life cycles and symbioses. Could inter-species or inter-kingdom interactions be a future focal area to further inform life cycle evolution?

London EvoDevo meeting (LED)

Posted by , on 25 September 2024

London EvoDevo meeting (LED)

Dear colleagues,

Given all the outstanding evo-devo work going on in the London area, we feel that a regular gathering to share recent discoveries and to network would be a real asset. Not too long ago there was such a meeting, and we are aiming to revive the spirit of it.

Our hope is to arrange a sustainable meeting that would occur once or twice a year. The current plan is to have half-day events that include short presentations/feedback (15 min + 5 min Qs) and socialization. Ideally, the location of these meetings will rotate among the organizer’s campuses. We wish to cast a wide net by defining “evo-devo” broadly and attract researchers working directly in the area but also those working on evolutionary or developmental biology looking to bridge to the other side.

We have arranged the rebooting of London EvoDevo to be November 8th on Queen Mary’s campus from 13:00 – 17:00. We hope that you or people in your group will join and potentially be willing to either apply for a talk for this meeting or the future ones.

For more information and to register, please follow this LINK.

We hope to see you in November!

London EvoDevo Organizers,

SciArt profile: Yoshinari Yoshida

Posted by , on 25 September 2024

In this SciArt profile, we meet Yoshinari Yoshida, a philosopher of science focusing on the conceptual and historical issues in developmental biology. Yoshinari enjoys drawing animals and plants, and have recently got into drawing primates, such as gibbons and orangutans, because of his research into in vitro models in comparative biology.

Can you tell us about your background and what you work on now?

I was born in Milton Keynes, UK, and grew up in Japan. I did my undergrad and Master’s in Philosophy and History of Science at Kyoto University, Japan, and Ph.D. in Philosophy at the University of Minnesota, USA. I am currently a postdoctoral fellow at the University of Exeter, UK. Throughout this academic career, I have studied philosophy of science, with a special focus on conceptual and historical issues in developmental biology. My central philosophical interest is in how various models and representations (e.g., “living models” such as model organisms and cell culture systems, and visual models such as diagrams and illustrations) play their roles in the production of knowledge about generality and diversity in developmental processes. My current project focuses on the prospects and limitations of in vitro models in comparative biology. I try to clarify how in vitro systems, such as organoids, play their roles as models in the context of cross-species comparison and reconstruction of evolutionary history. I examine experimental and inferential practices as well as interdisciplinary interactions among experts to tackle this philosophical question.

Were you always going to be a philosopher of science?

When I was younger, I was rather going to be a scientist. I was a kid who loved insects and extinct animals, and in my teenage era, I enjoyed learning about evolution and embryonic development. But I also liked the philosophical discussions about conceptual questions. When I was in the second year of my undergrad, I took the courses “philosophy of science” and “history of science.” I enjoyed these courses so much, and started thinking that studying these fields would allow me to fulfill both my interest in science and my love of philosophical discussions. I decided to major in philosophy of science, and since then, I’ve been in this field.

And what about art – have you always enjoyed it?

Almost yes. I was already into art when I was very little. I was a kid who kept drawing during lunch break in elementary school as well as after school. My favorite objects were monsters, robots, and manga characters. There were periods in my life when I was a bit away from doing art, such as during high school. But I’ve maintained my interest in art. Several years ago, when I was in my Ph.D., I bought a tablet and started drawing digitally. Until then, drawing had been a private hobby just for myself. But I began posting my artwork on social media and also drawing more constantly.

What or who are your most important artistic influences?

It’s not easy to name one specific artist. (I still lack systematic knowledge of art history.) But I’m often inspired by realistic oil paintings from the modern and early modern periods. My favorite is those paintings that are so realistic that they look as if they are photographs from distance, but consist of explicit strokes when seen closely. Those paintings make me think about how we see the world.

Orangutan – digital illustration. It was really fun to draw the unique three-dimensional shape of the face. I used a photo by Hollasue in Pixabay as a reference.

How do you make your art?

Currently I do everything using a painting app called Procreate in my tablet. When I see an object or scene whose shapes, colors, textures, or patterns I find interesting, I take pictures, which I may use as a reference later. Or, sometimes I become interested in a certain animal or plant, and search for images of the animal or plant and then start drawing it.

Radishes – digital illustration.

Does your research influence your art at all (or vice versa), or are they separate worlds?

Art is my major hobby that is a source of joy distinct from research in my life. But I think there are some connections between the two. For instance, I am interested in the role of images in science. I have some articles (one published, one currently under review) about how the use of specific types of diagrammatic representations contribute to knowledge production in science. I am also working on a side project with my colleagues about the role of speculation in evolutionary thinking, in which we discuss the power of illustrations. I think this philosophical interest of mine in images in science has a common root with my artistic interest in drawing and painting. My art is also sometimes influenced by my academic interests. For example, I’ve recently been into drawing primates, such as gibbons and orangutans. This was triggered by my current research project on in vitro models in comparative biology. I’ve read studies that apply advanced in vitro technologies to primates to elucidate human evolution, which made me interested in primates themselves.

What are you thinking of working on next?

There are a few ideas. I want to keep working on primates and drawing as many primate species as possible. That would become an interesting series! I’m also interested in making art that is related to developmental biology. Even though my primary philosophical focus has always been on developmental biology, I’ve not made art about this field. It would be fun to make drawings inspired by the normal developmental stages of chick embryos, mechanisms of collective cell migration, or tissue movements in gastrulation. Finally, I’m interested in trying oil painting. While I’ve drawn only digitally over the last several years, I love seeing oil paintings at museums. That would be an interesting new step.
