Our latest SciArt profile features Arpan Parichha, a PhD student in Shubha Tole’s lab in Mumbai. Arpan told us about his passion for using art to address important issues in science, such as gender equity, as well as communicating science to the general public.

Where are you originally from and what do you work on now?

I was born in Kolkata, India, and I now work at Tata Institute of Fundamental Research, Mumbai as a grad student in the lab of Prof. Shubha Tole. My thesis work involves understanding the role of canonical Wnt signaling in the developing telencephalic midline. I am examining how Wnt signaling dynamics are essential for several dorsal midline brain structures like choroid plexus, Cajal Retzius cells (CR cells), and fimbrial scaffold.

Were you always going to be a scientist?

Not at all. I always wanted to become a doctor and had zero clue about the life of a scientist. The society where I grew up imposed two choices for my career: becoming a doctor or an engineer. During my college days, I had an opportunity to live the life of a grad student for two months (when I was a summer research fellow), and it was when I decided to explore the world of academia. I found the life of a researcher to be cool and much more interesting than the conventional 9-to-5 job.

And what about art – have you always enjoyed it?

I have been passionate about art since childhood and joined an art school when I was eight years old. I am formally trained in landscape art and abstract oil painting. Now, I want to fuse abstract art with science to create something insightful.

What or who are your most important artistic influences?

I was deeply influenced by the scientifically precise artworks of David Goodsell. These paintings are mesmerizing and capture the intricate details of molecular and cellular processes inside the cell.

How do you make your art?

I use all kinds of media (digital, pencil sketch, oil, and watercolor) to create my artwork. These days I use an iPad to create my digital drawings. Sometimes I combine these two styles to create a hybrid approach. I try to make my abstract artwork in a way that it remains open to interpretation. Many of my paintings voice the importance of gender equality in science and the importance of women in STEM education.

I post my paintings and artwork on Instagram, YouTube, and Twitter. Besides abstract art, I make animated videos (using vector graphics) on PowerPoint, which explain a biology concept or increase public awareness of research.

Does your art influence your science at all, or are they separate worlds?

During my college time, I was fascinated by microscopy. Notably, I perceive confocal microscopy images as artworks. Art is really an integral part of my science. The artistic mindset helps me conceptualize biological questions and design new experiments for my research. As a grad student, I always scribble in my notebook when I’m designing experiments or have exciting results. Putting down my thoughts as drawings really helps me to think like a scientist. I always find it easy to communicate my science by drawing models, cartoons, and flowcharts.

What are you thinking of working on next?

I want to promote science and concepts of biology using Instagram, YouTube, and Twitter.

I have realized students and the young generation should be exposed to the fascinating life of scientists. Hence in many of my YouTube videos, I wish to highlight the person behind the science. Getting to know the scientists, along with their science, always gives that personal touch. After all, science is done by people for people. Unfortunately, the young generation is not as influenced by the life of a scientist compared to a Hollywood film star. Hence I strongly feel that science needs to be popularized in a creative way that attracts young minds.

 I have started posting a 1-minute video summary on YouTube of papers I read or hear in a journal club. These one-minute videos give the audience a flavor of exciting discoveries by scientists worldwide. For example, I explained how a scientist could study the neanderthal brain in a dish in a “YouTube Short” video. Moreover, I aim to spread awareness about public health by using animated YouTube videos. For example, in a recent video, I explained how alcohol can affect our brain and why we should say no to alcohol

In the future, I wish to make podcasts on my youtube channel where I can ask scientists about their life and how they got interested in science.

Thanks to Arpan and all the other SciArtists we have featured so far. We’re looking for new people to feature in this series – whatever kind of art you do, from sculpture to embroidery to music to drawing, if you want to share it with the community just email thenode@biologists.com (nominations are also welcome!)

I guess I am speaking for everyone when I say that the ISDB 2021 conference was a much-needed source of serendipity. Although postponed by a year, the conference brought together an excellent line-up of speakers with four keynote lectures, a Harrison medal lecture, a closing plenary lecture, along with 10 scientific symposia; all centered on developmental biology. It was a feast!! Oh, did I mention the nearly 400 posters? This is where we test the limits of how much knowledge one can acquire in a short amount of time.

In my view, this meeting was a great amalgamation of what we are doing, as a scientific community, to get a global understanding of the journey of life, starting from a single cell to the formation of the entire organism. Speaking of single cells; it became abundantly clear that single cell -omics techniques, like ‘single cell RNAseq’, are becoming mainstream bread-and-butter for understanding developmental processes. Each of the symposia I managed to attend had at least one talk where the technique was used to test and/or construct scientific hypotheses. We were joking that anyone playing a drinking-game, having to drink every time ‘single cell RNAseq’ was mentioned, would be, at the very least, unsafe for driving.

In the past, I have been skeptical about the utility of in vitro experiments in developmental systems: I mean, why would you use an in vitro cell/tissue culture system to understand what’s happening in vivo? in vivo systems are so beautiful to begin with!! I would say, this meeting changed my mind. For one, that’s probably the only way we can experiment with rhinoceros; but more importantly, I got the impression that we, as a scientific community, are reaching a critical mass of research and researchers who know the in-and-out of modelling in vivo processes in vitro. With organoids, gastruloids, axioloids, segmentoids, intestinoids, etc. leading the way, the era of -oids is upon us, and one can only imagine the endless possibilities it presents.

Here I have to mention a couple of personal highlights. The location: it was my first time at the Atlantic Ocean (I know I am a bit lazy that way), and this was one thing I am sure everyone at the meeting enjoyed thoroughly. A short walk from the beaches was a nature reserve that hosted flamingos, along with plenty of other interesting fauna. Also, meeting the speakers was a great opportunity to learn how one can shape their thinking to be a great scientist, as well as become an interesting human being. Exchanging ideas, while sitting on the lawn by the pool, made this one of the best meet-the-speakers session I have experienced.

Of course, the most natural thing that happens at conferences happened here as well, meeting old colleagues and friends, and making new connection with peers, despite all the corona-worries. Also, I hope every foodie got the opportunity to try out the amazing fish food in restaurants around the conference venue. I guess the conference organizers had realized the importance of networking, and pushed us to arrange for dinner on three out of five conference evenings, giving us additional social and informal bonding opportunities.

If you are curious about the study involving rhinoceros, and many other unpublished data, we have also compiled a list of various preprints discussed during the ISDB2021 meeting. So, feel free to check our preList for the meeting as well.

Niveda Udaykumar, Indian Institute of Technology Kanpur (IITK), Kanpur. India

This year’s ISDB meeting was one filled with exciting opportunities to dive into the fascinating field of developmental biology. I was looking forward to this conference from the moment I submitted my abstract!

My experience at this conference was very fulfilling with scientific and personal realizations. I have very fond memories and experiences of this conference, which was my first solo international trip!

I liked several aspects of this conference, the first being the diverse speaker line-up, from the Harrison Medal lecture, the Keystone lectures, symposium speakers, and the oral presentations. The line-up of speakers catered to the scientific interests of most of the attendees, if not all! The talks ranged from trying to recapitulate human somitogenesis in vitro to evo-devo and metabolism. I was impressed with the poster session, with about 400 posters that showcased exciting ideas and hypotheses from all around the world.

Another great aspect was the ample time for the participants to interact with each other. This time was particularly useful as I got to discuss my research with several people, get feedback and talk about potential future positions with PIs. On some days, this time was spent catching up with old colleagues and friends. I appreciated the organizers’ efforts in the networking sessions, ‘Meet the Speakers’, where the participants could interact with any speaker of their choice. The parallel session of ‘Meet the Editors’ too well-received, where the Editors of prominent journals such as ‘Development’ and ‘Cells and Development’ interacted with the participants and familiarized them with their potential manuscript submissions.

Finally, I felt that the choice of location for the conference was perfect. We were privileged to have clear beautiful blue skies with sunny weather on most days, and the serene beaches of the Algarve were breathtaking. As an attendee of the conference, I know that I came back home refreshed and motivated, caught up with old friends, and made new friends, and I thank the organizers for their efforts in organizing such a fantastic conference.

Girish and I (read mostly Girish) have prepared a preList of the preprints that were mentioned in the ISDB conference. Please take a look at it, and if we have missed any, please don’t hesitate to contact either of us.

There have been long-standing debates around the risk of selective serotonin uptake inhibitor (SSRI) use during pregnancy due to the potential effects on fetal brain development. Our studies, which have been recently published in Development, identify an essential role of transient serotonin uptake transporter (SERT) expression in non-serotonergic neurons during neural circuit development in the hippocampus, and disrupting this SERT function leads to sex-biased deficits in hippocampal electrophysiology and behaviors. This suggests that cataloguing the risks of SSRI exposure during particular timing of human fetal brain development could be critical to enhance the sensitivity of the investigations. Differences in cognitive behaviors in the male versus female mice imply that certain neural circuit dysfunctions, particularly in females, resulting from early life SSRI exposure may not manifest until later life and under certain environmental conditions. An outstanding question is how the findings in mouse models may help refine SSRI uses, to safeguard the mother and the offspring. We would appreciate comments and suggestions on our work.

“One of the things that we’re really interested in is whether or not we can take these genes that are used in carnivory and pop them into crop plants”

Dr Tanya Renner

In the latest episode of the Genetics Unzipped podcast, we’re looking at the gruesome world of plants eating animals. There’s something unnatural about carnivorous plants. We’re so used to plants being at the bottom of the food chain, that to see them trapping, killing and eating animals seems to go against the laws of nature. But of course, carnivory in plants is very real and has evolved multiple times in response to a lack of nutrients. We speak with Dr Ulrike Bauer about the biomechanics of how pitcher plants make their surfaces so slippery, Dr Kadeem Gilbert tells us about what is able to survive inside a pitcher plant’s death trap, and Dr Tanya Renner talks about how she’s trying to put sundew genes into crops.

Dear Node Colleagues,

This is my inaugural Node post. Around 1990, Stephen Jay Gould dedicated my copy of his Ontogeny and Phylogeny (1979), writing, “Thank you for tackling my real book.” As a chemical engineer, I took it seriously when Gould whispered that development is not encoded in the genes and to forget natural selection.

The succeeding thirty years of lab work by scientists and scientific artists attributing morphogenesis to mechanical causes has garnered many papers and hundreds of illustrations covering most complex taxa. Recently, we demonstrated vertebrate origins in self-organized patterns that occur in the predictable geometry of serial, sequential cell division.

The authors hope that the many facets of our work will inspire further investigation. We invite comments and possible collaboration.

13–14 September 2022, University College London

The Symposium was organised by Alison Hawkes, Jonathan Slack, Jim Smith, Claudio Stern, Cheryll Tickle and Neil Vargesson. Kindly supported by the British Society for Developmental Biology, Oxford University Press and UCL.

To many readers of the Node, Lewis Wolpert, who died on 28^th January 2021, was above all a developmental biologist—one of the most distinguished and influential of his generation (Figure 1). But of course he was much more than this, and the organisers of this meeting in his memory devoted the first day to Lewis the man (Figure 2). We heard from his cousin Frances Jowell about his early life in South Africa, about his aunt Helen Suzman (the politician and anti-apartheid activist), and about Lewis’s own hatred of apartheid. Frances also explained how Lewis arrived in London, having hitch-hiked up Africa and spent some time working as a soil mechanic in Israel. Cheryll Tickle continued the story of Lewis’s early life by recounting how his friend Wilfred Stein introduced him to the mechanics of cell division and how this kindled his interest in developmental biology, leading to the articulation of the French Flag problem and his work on hydra and the chick limb.

Lewis was a charismatic speaker, performer, and communicator, and Jim Smith spoke about Lewis’s contributions to the public understanding of science, illustrating his points with clips from Wolpert’s Medawar lecture of 1999. He was followed by Robert McCrum, former editor-in-chief of Faber and Faber, who discussed Lewis’s writing, and then John Geddes, Professor of Psychiatry in Oxford, who explained how Lewis’s book on depression, Malignant Sadness, had had such an influence on both public understanding and on the field of mental health research. The day finished with Lewis’s stepson Luke Leitch speaking about Lewis’s forays into journalism, with Tim Arnett speaking about Lewis’s sporting life, and especially tennis on Parliament Hill Fields, and then with Lewis’s daughter Miranda speaking about Lewis at home. Finally, Nigel Townsend spoke about one of Lewis’s lesser-known activities, his support for the Y Touring theatre company, which produces plays that encourage schoolchildren to explore the social, moral, scientific, and political questions raised by areas such as stem cell research.

The second day of the meeting focussed on the science in which Wolpert was interested, and speakers included colleagues and collaborators as well as young scientists who had been influenced by Lewis and his work, many of whom said how much they would have liked to have met him. The speakers would have graced any major scientific meeting, and included Claudio Stern, Maria Leptin, Alfonso Martinez-Arias, Lara Busby (recipient of the Summerbell award and introduced by Amata Hornbruch), Cliff Tabin, Neil Vargesson (Lewis’s last PhD student), James Sharpe, Kristina Stapornwongkul, Brigitte Galliot, Elly Tanaka, Peter Holland and Denis Duboule (Figure 3). Areas of research included gastrulation, limb development, modelling, regeneration and evolution, and each speaker described how Lewis had influenced their work and their thinking.

The Symposium made clear Lewis’s influence on the field of developmental biology, his ability to transcend his field and, through his charismatic performances, his power to inspire and inform both scientists and non-scientists. When video clips of him were played at the end of the first day, the audience leant forward as one, listening intently to what he had to say. We also heard that Lewis loved discussing science, especially with the young, and was never slow to explain exactly what your data really meant. As a self-confessed ‘contradictor’ he was always questioning and challenging others, encouraging them to think more deeply about their views and why they differed from his!

We’d like to think Lewis would have enjoyed the meeting. He would have been pleased that his ideas are still informing our experiments and he would have asked lots of questions (something he always asked his PhD students to do). Most importantly, we think he would have been pleased by the great affection in which he was held, and by how pleased we all are that he made the move from soil mechanics to developmental biology.

5 simple tips to make sure people love rather than loathe your next presentation.

All too often you find yourself in the audience, watching a scientific presentation with a fully-scrunched grimacing face as you despair slightly at the torrent of PowerPoint slides being projected into your eyeholes. 

Whether it’s the classic forty slides for a ten-minute talk, the essay being read aloud to you or the dreaded illegible yellow text, presentation disasters are everywhere. 

But it doesn’t have to be like this. You can break the trend. You can be better. You just have to follow a few simple rules.

1. Tell a story

This is super clichéd, but it still seems to be rarer than a paper returned without revisions. You have to tell your audience a story. Have a clear beginning, middle and end. Don’t just rattle through every single experiment you’ve done over the past few months and bombard your audience with every shred of data: tell them a story. Bring them along for the emotional ride we all know lab work is. Research is full of ups and downs, repetitive little failures and surprise successes. Expand on those. Tell people what you were hoping for, what you ended up with and how you felt about that. 

When it comes to crafting your science story, here are some helpful prompts:

• What’s the question or problem you’re addressing?
• Why should anyone care?
• What did you do to answer that question?
• Were there problems you had to overcome? How did you manage that? (People love a tale of conquered adversity)
• Got data? Awesome! What are the main findings?
• No data? Awesome? Here’s your chance to open the floor up to troubleshooting (Okay okay, I know it’s not awesome but quite often you’re going to lack data, so here’s a chance to explain what you did and I bet there’s someone who has an idea about why didn’t get the data you expected. Also, unexpected data are the basis of discovery — remember that).
• If you’ve thought about what research comes next, leave people with a taster of what you have planned. They’ll be excited by the prospect of a sequel – who doesn’t love a sequel? 
• And what did you conclude from all this amazing work? Wrap it up in one slide. ONE SLIDE — YEAH YOU HEARD! ONE SINGLE SLIDE.

2. Keep it minimal

This is not your thesis — do not have a ton of text on your slides. You’ll just end up reading it aloud and the audience won’t be listening to you because they’ll either be reading the essay you slapped in front of them or on their phones tweeting about the terrible talk they’re stuck in. 

Instead, have a title, a few supporting bullet points and a visual. Talk about what’s on each slide: explain graphs, images and diagrams. You know the data inside out but your audience doesn’t. So walk people through your thinking. Explain what it all means – it keeps them engaged and actively listening to you.

3. Make it pretty

This isn’t superficial: it matters. If your text changes size on every slide, your titles are in a new position every time you hit ‘next’ and your images are blurry, people will be distracted. 

An aesthetically pleasing, neat and well-formatted (i.e., consistent!) presentation helps to keep people focused on what you’re saying. It also says you care about the experience of the people looking at your work. 

The layout of a pretty presentation may go unnoticed, but the layout of an eye-wateringly ugly presentation is often the only thing people will see.

BONUS PRO POINTS: skip slides altogether. Everyone hates PowerPoint really, so bin it. Rise above it. Try giving your talk with just a blackboard or whiteboard. Stand in front of it. Gesticulate wildly. Draw the data you need to enhance your points. Tell your story. Own that board! This means you really need to know your stuff. But you do. Right? Be the blackboard talk person that everyone remembers.

4. Have a point

This ties in with my first rule about telling a story, but it’s worth reiterating. 

What’s the point of your presentation? 

Are you talking about one key new finding? 

Summing up your last six months of work? 

Presenting a problem that you hope to troubleshoot? 

Whatever it is, make it the focus of your presentation; don’t try to do everything at once. Again, this isn’t your thesis. You want to leave people with a clear take-home message. You don’t want them coming out, scratching their heads, wondering what just happened and if they can somehow reclaim the last hour of their lives.

5. Be a human

Presentations can be daunting, but if you relax and learn to present with a little bit of personality, maybe even some humour, you’ll find they go a lot smoother. 

Take your time. Take longer than you think you need. 

Breathe. 

Think about the points you’re making. Talk to your audience like you would a friend in the office or the lab. There’s no need to plough through a talk, eyes down, like a robot reading a script.

Get excited by your results. Get exasperated by your failures. A little bit of empathy goes a long way. You can be sure almost everyone in that audience has been through a similar experience, so sharing your feelings here gets them on board. They’ll care. And if they care, they’ll listen and remember your talk. 

You might even find you actually end up enjoying it because, all of a sudden, people are enjoying your talk! You’re the expert! And you’re crushing it!

Okay, you got all that? Here’s a summary just in case:

• Tell a story with a beginning, middle and end — keep people engaged
• Only include essential info on your slides
• Make your presentation pretty and consistent
• Address one main point
• Be a human — be a friendly, potentially entertaining, human if at all possible

There you go: just a few simple rules to make sure your presentations don’t inadvertently bore people to death.
