With many of our events going virtual (yay!), we think our team deserves a big round of virtual applause 👏. We are working hard behind the scenes so you can advance your virtual training, be it attending a virtual conference or a virtual course – yes, you read correctly – courses! We are super excited to bring them to life, but more on that in another post😉.
Meet Elisabeth “Liz” Wintersteller. She is the Course and Conference Officer who turned this year’s BioMalPar conference into a hugely successful virtual event. We admit it was a bit stressful to organise an event with more than 400 participants in a completely new format in such a short time, but Liz’s light-hearted and cheerful personality made it all possible.

What are the challenges/differences of organising a virtual conference?
I miss seeing the excited faces of the participants upon arrival.
How have you adapted your role during lockdown?
It wasn’t too difficult to adapt to working from home, but I miss the team lunches!
Upcoming virtual events in 2020 Liz is organising:
Virtual meetings are rapidly gaining popularity, due largely to the necessity of continuing knowledge exchange during the social isolation brought on by the Corona pandemic.
Even before the pandemic, EMBL´s Course and Conference Office was already exploring options to improve our services and the event experience on-site, including the option of digital poster presentations.
Our software provider iPosterSessions comes with easy to use WYSIWYG templates. Users can display high-resolution images, videos & animations, and the content can be updated at any time right throughout the conference – allowing poster presenters to present their research digitally and dynamically.
If you are presenting a digital poster at an upcoming (virtual!) meeting, here are eight tips to help you on your way:
Download the official template from the software provider
Most digital software providers have an official template that you can download – use it! This will reduce the risk of glitches, resolution problems and sizing issues in the final product, and you know from the outset what you have to work with.
Check out the tutorials
No two digital poster tools are the same, so take the time to browse through the online tips and tutorials to make sure you are comfortable with the software before starting. It will save you a lot of frustration in the long run!
Make your design eye-catching – it should stand out from the crowd
This is the same principle as creating a printed scientific poster – there are so many of them, so make sure yours stands out! It should be eye-catching and visually appealing. Include clear data representations, and make sure the text is to the point. It should grab attention but not explain every little thing about your results – that’s your job during the discussion.
Use media – images, sounds, video. Check that they work and display properly
Graphics and media can express details more quickly and memorably than paragraphs of text, so have a think about how you can present your work in this way and put some time into it. Be sure to check that the media files work with the software, and test every file to make sure they display or play properly.
Link to external resources
Digital posters differ from printed posters in that you can generally link to other pages online – so if there is a great external paper or online source you want to link to in order to explain your point in more detail, do it! Your audience will be grateful to have further reading handed to them on a plate if they want to find out more after the poster session.
Check your work
This should really be a no-brainer. Check your work is complete, correct and final before publishing your poster! Silly mistakes only show that you haven’t put as much time and effort into the work as you probably should have, so get someone else to go over your poster before you release it to the conference community.
Practice your presentation
Yes, it’s a digital poster presentation, and no, you won’t be talking face-to-face with your audience as you normally would, but you still need to practice your presentation beforehand and know exactly what you want to say and how you want to say it. It may feel strange online, so try presenting the poster online with a colleague or your boss (e.g. with Skype, Zoom, Google Hangouts) and get them to give you feedback and pointers.
Stick to the publishing deadline
There are deadlines for a reason, so please stick to them! You don’t want to risk your poster being excluded from the poster presentation because of tardiness. Give yourself plenty of time in case of any issues that may arise with uploading or compatibility (this shouldn’t be an issue if you followed the template and guidelines, but sometimes computers have a mind of their own!).
By guest bloggers and EMBL AV experts Christopher Höhmann and Jan Abda
Virtual events are on the rise, largely due to the necessity to adapt to the physical distancing enforcements and travel restrictions brought on by the COVID-19 pandemic.
EMBL is continuing to offer advanced training for the scientific community as safely as we can, with many events pivoting to virtual. With speakers spread all over the world with different internet connection speeds, technical support and varying levels of experience with virtual presenting, the EMBL Audiovisual team have put together a guide on how to make sure your presentation is smooth and you come across as professionally as possible for your digital lecture.
Choose your location wisely
Make sure you choose a location without a window in the background, as this will result in a high contrast, causing you to appear dark and hard to see. Make sure the background isn’t too busy, or has anything that might draw the attention away from your talk.
Pick a quiet room
When selecting the location for your presentation, make sure there is no loud background noise and that you won’t be disturbed. Who can forget Prof. Robert Kelly’s live BBC broadcast starring his adorable children as unexpected guests!
Use a headset
Ideally, use a headset in order to ensure the best possible sound. It may feel a bit strange at first, but your audience will thank you for it!
Check out a review of some of the best options here.
Use a wired connection if possible
If you have the option, connect your device directly rather than relying on a wireless internet connection. This will help avoid any possibly wireless instability or network breaks.
Avoid using the web browser
There are many different streaming software options out there. If there is a video conferencing app available for the event you are presenting at, for best results download this in advance to use for the live stream rather than relying on the less reliable web browser version.
Close other programmes
In order to save bandwidth and processing power, close all unnecessary applications on your device before your presentation starts. This will result in a smoother streaming of your talk.
Share your entire screen – carefully!
It always comes across better if you share your entire screen rather than just your keynote or PowerPoint presentation. Just be sure to keep in mind that as soon as you share your screen, everything that you can see can be seen by your audience, so be aware of what you have visible!
Troubleshooting on Macs
If you have a Mac (running Mac OS Catalina 10.15), you may have some initial problems with sharing your screen. If this is the case, try the following:
Go to System Preference → choose Security & Privacy → select the relevant app under Screen Recording and tick the box.
The (VC) app will have to be restarted in order for the changes to take effect.
Unshare before question time
When you have finished your presentation, end your screen sharing before the Q&A session starts. Your audience wants to see YOU when they are asking questions about your presentation, not the final slide of your talk.
Make it readable
Remember, people will be watching your presentation on different devices with different-sized screens. Make sure your digital presentation is clear and that the font is readable – if you can’t read it easily, neither can your audience.
Test, test, test!
At EMBL, our AV team will test the setup and conditions with you before the live event. Make sure that you carry out the test with exactly the same set-up as you plan to use on the day to eliminate the risk of any nasty surprises.
So now there’s nothing stopping you from giving a smooth and polished presentation at your next virtual conference. Take the time to get familiar with your streaming applications, practice and test the software in advance, and you shouldn’t have anything to worry about!
Jan Abda and Christopher Hoehmann are dedicated Audiovisual Technicians in the EMBL Photolab, and are responsible for ensuring the technical aspects of our onsite and virtual conferences and courses run as smoothly as possible. We would be lost without them!
June 5th is World Environment Day, and this year there is a clear message – that society should take “urgent action to protect biodiversity”[i]. But what does this mean in practice? If, like me, you feel that we are on the cusp of a sea change when it comes to talking about environmental issues, you may also spend a lot of time thinking about what on earth society can do to respond to the challenges of climate change or mass extinction.
It was, therefore, with interest that I came across the publication of the World Scientists’ Warning of a Climate Emergency[ii] (the ‘Warning’) in the journal of the American Institute of Biological Sciences (“BioScience”), which demands that scientists give their name to a “clear and unequivocal declaration that a climate emergency exists on planet Earth”. Published exactly 40 years after the first World Climate Conference in Geneva, the Warning now has over 13,500 signatories, who commit to the principle that scientists “have a moral obligation to clearly warn humanity of any catastrophic threat”, and to “tell it like it is”.
The Warning not only provides us with statistics, policy suggestions and solutions, but it is a rallying cry for society (and particularly scientists!) to take action. What I find so fascinating about this initiative is that it causes us to stop and think about our role in this debate. What part could, or should we play in issues affecting the future health of planet Earth? How does one reconcile or balance individual action with national or global priorities and policy decisions?
The Science & Society Programme provides a vehicle to explore exactly these kinds of issues through an EMBL lens – we seek to provide a neutral platform for multi-disciplinary dialogue on the ethical, legal and social implications of the life sciences, and in particular, of EMBL’s research.
In fact, the Science & Society 2020 Conference, “Our House is Burning: Scientific & Societal Responses to Mass Extinction”, will specifically address the topic of biodiversity. It will consider the impact of environmental changes on biodiversity, ecosystem services, and human well-being from a societal perspective. Crucially, focus will be placed on potential solutions and types of action: from activism to political strategies, and from local grass-roots conservation groups to global youth movements. It will also evaluate the application of intervention methods, from sustainability solutions to data science and beyond. And, this year, it will take place as a virtual event, with a flat fee of 20 Euros (and free to students under 18). Click here to sign up!
The issues in our upcoming Conference are clearly topical, and the Warning itself also focuses on ‘Nature’ as one of the six key steps for action – to “protect and restore Earth’s ecosystems”. EMBL’s activities and research also directly intersect with five of the six steps for action outlined in the Warning; Energy, Short-lived pollutants, Nature, Food and the Economy. As an organisation, it is, therefore, clear that EMBL has a part to play in this debate. The Green EMBL group was set up last year to lead EMBL’s activities in addressing its environmental impact. The group is bottom-up, and open to all EMBL scientists and staff who have an opinion, idea or desire to act to reduce the environmental impact of EMBL.
I am keen to hear from you. Did you sign the Warning yourself? How do you view your role as a scientist in this issue, and do you consider yourself a ‘Science Activist’? If you are willing to share your view on these questions, or want to know more about the Conference or other Science & Society events, please get in touch.
Despite the coronavirus pandemic, EMBL’s BioMalPar conference could still take place online. Nearly 400 participants from around the world attended the virtual meeting to share the latest research into Plasmodium, the malaria-causing parasite.
From onsite to digital
There were both benefits and drawbacks to hosting the conference online. On the plus side, the conference’s barrier to entry was significantly reduced, allowing for a higher-than-usual number of participants to attend, from all over the world and at different stages of career. There was more interaction between speakers and the audience and those who would not normally feel comfortable asking a question in a conference hall could do so more comfortably online. The conference was slightly shorter than usual – just two half days – so there were fewer talks overall and no possibility for workshops; however ‘special interest’ lectures were held instead. Poster sessions could still take place with posters remaining online after the session for more leisurely viewing. On a more specific note, Dr Julian Rayner, a member of the BioMalPar Emeritus Steering Committee, remarked that he missed the asparagus stalls in the streets of Heidelberg, where the conference normally takes place. Asparagus or not, it’s remarkable that, in the face of real challenge and uncertainty, the EMBL BioMalPar conference could still take place, now sixteen years in the running.
The conference began with opening remarks from co-chairs Alfred Cortes of ISGlobal in Spain, Silvia Portugal of the Medical University Heidelberg in Germany and Sam Wassmer of the London School of Hygiene and Tropical Medicine in the UK. They emphasised the novelty of the online conference and outlined some ground rules.
Emerging Challenges and New Tools
The first session of the day was on ‘emerging challenges and new tools’ and was chaired by Andy Waters.
Laurent Dembele of the University of Bamako, Ghana, spoke on the subject of artemisinin resistance. Mutations to a protein called Kelch13 prevent the antimalarial from working, allowing the parasite to become dormant in the blood and to ‘reactivate’ when the drug is no longer in the system. Dembele evaluated two antimalarial drugs (KDU691 and GNF179) in vitro which target P14K, a protein that mediates the aforementioned dormancy. He concluded that KDU691 can selectively kill the dormant Plasmodium rings after treatment with artemisinin, but that GNF179 can kill both dormant and non-dormant rings and was active at multiple stages of the malaria parasite life cycle. A combination of artemisinin and GNF179 could mitigate the risk of artemisinin resistance, it was suggested. This has direct applications to SE Asia, where artemisinin resistance is particularly prevalent.
Simone Reber of the Humboldt University of Berlin spoke about her research into Plasmodium tubulin, a potential target for drug development. Tubulin is a ubiquitous protein that controls cell proliferation and so has direct applications to the treatment of malaria, a disease that depends upon cell replication. Simone characterised tubulin in the malaria parasite and considered drugs that could inhibit it and compared Plasmodium tubulin to a similar shaped human tubulin. A concentration of 2.5 micromoles of inhibitor could kill the Plasmodium tubulin but not the human tubulin, for which 20 micromoles were needed. Tubulin is a promising target for malaria treatment but research into it is limited by the protein’s small size. For 150 micrograms of tubulin – in itself, a rather small sample – 5 litres of blood is needed.
Regina Rabinovich of ISGlobal gave her special interest lecture on COVID-19 and its impact on ‘research and beyond’. She took a step back from the specific biology of malaria to consider global public health in general; ‘from the mitotic spindle to global malaria strategy’, as she called it. She offered a concise history of malaria eradication and addressed recent developments in strategy: a shift away from blanket solutions to region-specific programmes. She also shared the broad public health lessons that we can learn from COVID-19, with particular emphasis on accelerating R&D efforts and cultivating a sense of urgency. She concluded with remarks on the potential impact of the coronavirus in Africa both socially and epidemiologically, with reference to data modelling from the WHO and Imperial College London.
Alfred Cortes introduced the second session on ‘parasite biology’.
First to speak was ManojDuraisingh of the Harvard TH Chan School of Public Health. He spoke on how the P. falciparum egresses from red blood cells. He detailed that the PfPP1 protein is essential for such egress and that it coordinates multiple signals early in egress. He also outlined the role for Hect E3 ligase in egrees and that PfPP1 regulated cGMP levels through PLT-GCalpha.
MathieuBrochet of the University of Geneva spoke on his work into the Plasmodium protein, PKG. This protein was previously known to control calcium signals called Ca2+ which, in turn, are critical for Plasmodium life cycle stages in the human and mosquito, namely erythrocytic egress and gametocyte development. How PKG influenced these Ca2+ signals was previously unknown, however, so his research sought to identify a partner protein. He identified ICM1 as this partner protein, finding that when ICM1 was distributed, so was egress, invasion and Ca2+ mobilisation.
FranckDumetz of the University of Cambridge spoke about his investigations into the presence of ‘G4’ proteins in the P. falciparum genome and whether they play a role in post-transcriptional regulation. He first identified 681 ‘rG4s’ in the transcriptome and used both in vitro and in vivo approaches to find that rG4s can have a regressive impact on translation when they appear on the transcribed strand of a gene. He continued to suggest that there may be novel RNA-binding proteins in Plasmodium that are involved in regulating rG4 motifs.
Venessa Zuzarte-Luis shared her research into why Plasmodium replication in the liver of mammals is particularly high, producing tens of thousands of parasites, compared to replication in reptile and avian species, which only produce dozens of parasites. Vanessa states that this disparity is caused by the parasite’s utilisation of liver-specific methionine adenosyltransferase enzyme (MAT1), and the capacity of that enzyme to generate unlimited amounts of S-adenosylmethionine (SAM). SAM is capable of reverting the impairment of infection, suggesting that the parasites use this abundant resource.
“Omics” Approaches and Evolution
After a poster session on Slack, Julian Rayner began the third session on “omics” approaches and evolution.
Franziska Hentzschel of the University of Glasgow presented her research into the parasite-host interplay in vivo at the single-cell level. She used flow cytometry and single-cell RNAseq to characterise parasite and host cells in circulating blood, bone marrow and the spleen of P. berghei-infected mice. She found that the spleen was preferred as the extravascular site for Plasmodium reservoirs, with the earliest ring stages enriched in putative reticulocytes found there.
LianneLansink of the Queensland University of Technology and the University of Melbourne detailed her research into how the malaria parasite adapts in the human host to changes in the environment. She created an environment of lipopolysaccharide, a condition which causes low blood pressure. She reported that this impaired the maturation of the parasites in vivo. The condition also affected parasitic gene expression; ribosome genes were down-regulated and other genes were perturbed in single parasites in a life-stage dependent manner.
Epidemiology and Surveillance
The second day of the BioMalPar conference began with a virtual pub quiz. Sam Wassmer then introduced the fourth virtual session of the event: ‘epidemiology and surveillance’.
ChrisDrakeley of the London School of Hygiene and Tropical Medicine gave a talk on the use of serology in understanding malaria transmission dynamics. He outlined several use cases of serology in malaria-endemic regions and emphasised the advancements in serological technologies; multiplex bead assays and protein/peptide microarrays allow for the assessment of proteome-wide immune responses which allows for greater granularity of analysis, looking at specific antigens or antigen combinations that cause specific immune responses.
MarioRecker of the University of Exeter spoke about understanding individual-level variations in malaria susceptibility and acquisition of clinical protection. His study sought to identify robust inferences of individual-level protection or susceptibility to malaria by analysing a longitudinal systems-immunological cohort study of Junju, a region of Kenya. He found that one of the most important risk factors to malaria is the number of previously experienced episodes which correlates positively with probability and number of clinical episodes during the upcoming transmission season. He also found that birth year can also have a significant and lasting impact on a child’s susceptibility to clinical malaria, due to the child’s exposure to Plasmodium early on in life.
ManuelaCarrasquilla spoke about her research into genome sequencing in Colombia to determine the history of P. falciparum. She analysed 151 clinical samples of the parasite collected in a regional hotspot during a 2016 outbreak linked to mining activities. She determined that the Colombian P. falciparum populations show high levels of genetic structuring and confirmed the presence of five major parasite lineages overlapping in time and space which have been shown to have important functional variation, including drug-resistance genes. Then, combining epidemiological data over a two-year period, she found that almost a third of infections show evidence of shared recent common ancestry, suggesting that increasing mining activities created an opportunity for polyclonal infections and outcrossing.
SimonKigozi of the London School of Hygiene and Tropical Medicines presented the results of his analysis of outpatient surveillance data from four health facilities in Uganda. The malaria burden had shifted from younger to older individuals as a result of malaria control methods including long-lasting insecticidal nets (LLINs) and indoor residual spraying of insecticide (IRS).
Pathogenesis and Immunology
SamWassmer began the fifth virtual session of the conference on ‘pathogenesis & immunology’.
BrittanyRiggle of the NIH was first to speak on the subject of pathogenesis and her work into CD8+ T cells as a potential avenue for treating cerebral malaria. Using multiplex immunohistochemistry in post-mortem brain samples from children with or without cerebral malaria and with HIV. Diagnosis of cerebral malaria increased the number of CD3+CD8+ T cells engaging the cerebrovasculature. HIV co-infection further increased this engagement. Riggle suggests that CD3+CD8+ T cells could be a promising target for adjunctive therapy for cerebral malaria.
HannahFleckenstein of Heidelberg University Hospital spoke about her research into how P. falciparum malaria parasites persist at low parasitemia for months in the human host in the absence of the Anopheles mosquito vector, a poorly understood phenomenon. In the dry season in Mali, the parasites spent longer in circulation before adhering to the endothelium. This adhesion is mediated by knob-like structures on the surface of infected red blood cells which allows for the avoidance of splenic clearance. She found that, in dry season parasites, decreased adhesion resulted in higher levels of splenic clearance which was sufficient to maintain low parasitemia.
Speaking on the subject of monoclonal antibodies, LawrenceWang of the NIH presented his findings into a sporozoite-neutralising monoclonal antibody called L9. The mAb could immobilise sporozoites in the skin and the liver and cause a phenomenon called ‘dotty death’. When asked why monoclonal antibodies would be preferred over mass-market drugs, which are cheaper and less laborious to produce, Lawrence responded by saying that some mAbs can offer potentially life-long protection and are a halfway house between a drug and a vaccine.
EmiliePollenus of KU Leuven spoke about the role of CCR2 in the resolution of MA-ARDS (malaria-associated acute respiratory distress syndrome). This condition is one of the health complications that malaria can cause, contributing to its 400,000 annual death toll. Those with the condition who do not have access to mechanical ventilation have an 80% risk of death, while those with it have a 10-40% risk. Pollenus found that the number of CCR2 monocytes increased during resolution after treatment with antimalarial medicine. In mice where the CCR2 protein was silenced – known as CCR2 KO (knock out) mice – there was a reduction in the number of inflammatory monocytes in the lungs and the spleen, however, this did not affect the resolution of the alveolar edema. Eosinophils – a type of white blood cell – completely disappeared from the lungs upon infection and reappeared with resolution but not in CCR2 KO mice.
CarolaSchaefer of the Seattle Children’s Research Institute spoke about creating a laboratory model for P. vivax infection to test interventions against the disease. Using the P.vivax liver humanised mouse model, with the addition of human reticulocytes, parasites were able to invade and replicate Schaefer could also observe gametocytes that were transmitted to mosquitoes in preliminary experiments.. She then tested the in vivo model with P. vivax Duffy Binding Protein (PvDBP) antibodies, an antibody that could potentially inhibit parasite invasion of red blood cells. 95% protection was observed, providing evidence that PvDBP is a promising target for future therapies.
SilviaPortugal opened the final virtual session of the conference on transmission biology.
DennisKlug of Inserm in France presented his research into the function of the protein TEP12 in antiparasitic immunity in Anopheles mosquitoes. When the protein was silenced, there was an increased parasitic load in P. berghei infections in An. gambiae and An. stephensi mosquitoes. However, there was a lower parasitic load with P. falciparum infection, suggesting an unknown adaptation of this parasite species.
AureliaBalestra of the University of Geneva discussed her identification of CDK-related kinase 5 (CRK5) as a critical regulator of atypical mitosis in the gametogony[KC1] which is required for mosquito transmission. This kinase interacts with a single Plasmodium-specific cyclin (SOC2), suggesting this cyclin/CDK pair controls DNA replication and M-phase progression.
InesBento of the University of Texas Southwestern Medical Centre presented her findings into mosquito-human sporozoite transmission. She found that sporozoites in the salivary glands of the mosquito are in synchrony with the vector’s behaviour, leading to lower parasitic load in the day compared to the night, when the mosquito is more prone to bite.
Bento’s talk concluded the session and was the last talk of the conference. AndyWaters then gave a memorial presentation on Shahid Khan, a malariologist who passed away in late 2019. He began his career with a degree in Parasitology from the University of Glasgow and then worked as a technician at the University of Oxford. He completed a PhD at Cambridge and a Postdoc at NIMR in London. Tributes were made to Shahid by his colleagues; he was described as the ‘sunshine’ of the laboratory and recently wrote a children’s bedtime story entitled ‘There’s a mosquito in my room’, which is available to download here.
The conference was formally closed with remarks from AndyWaters and JulianRayner. They called the virtual meeting a successful and ‘wonderful experiment’.
