Tested AMADEUS free tracking software developed by jpmyrmecol by simply throwing some of my planaria in a plate and recording a video, and it seems to work pretty nicely. The only thing I had to change in the workflow was the threshold for segmentation, everything else it did itself.

A reproduction–cancer trade-off has long been hypothesised in animals: greater reproductive effort may increase tumor risk. In our new paper, we find evidence for this trade-off in the cnidarian Hydra oligactis. @RSocPublishing doi.org/10.1098/rspb...

It seems there is a problem in the form when trying to rate the bowers. I cannot give the same note twice in a row for two bowers. it just skips a line and delete the answer to the previous bower when I try to do it. I am using google chrome as a browser.

New IScience paper (link to the article bellow): Invasive species that are really good with dealing with DNA damages and repairing them are a problem for our ecosystems and we tested this using freshwater planaria. (1/4)

🚨In our latest preprint 🚨 we discovered that tumour prevalence is higher among captive species that enjoy greater public and scientific popularity and this is creating serious bias in comparative oncology studies (link to the paper bellow). Here is what we found 👇👇👇

A tumoural hydra from my laboratory with a lot of supernumerary tentacles (only tumoural individuals develop that many tentacles), and a little bud growing on top of it. We nickname those hydras "pumpkin" because the tumour grow so big it turns hydras into a pumpkin shape.

A freshwater Hydra from my lab with a tumour so big it looks like more a pumpkin with tentacles rather than an hydra. It's more a tumour than anything else yet it can still eat.

Are small trends observed between body mass and longevity enough to refute Peto's paradox? I don't think so, and in my new paper I show that those trends are so uncertain that we cannot conclude much from them. We need better stats in those studies. royalsocietypublishing.org/doi/epdf/10....

I would be shame if funding to study tumoral processes in hydra gets discontinued. I am really keen to know why so far only one species of hydra develop tumours and not the others!

📰 ❤️ 🦠 New paper out! In this study, we found that transmissible tumours, much like some parasites, can change the way their host looks and behaves to benefit themselves. Link to the paper: elifesciences.org/articles/97271

If you're an Australian student interested in exploring the impact of human activities on wildlife and considering an honours project in 2025, I have a couple of exciting opportunities you might want to check out! Send me an email! #scisky #cancer #evolution #Australia

They are Cura pinguis. I have had issues taking good pictures because they move too fast under my dissecting microscope (nearly all of them are blurry). Any advice on prevent them to move too much without killing them? I need better pics for my talks and would be happy to send them to you.

The development is abnormal, as this species typically has only one head (unless it is producing a bud). An abnormal tree-like hydra can appear as shown in the picture below. Bottom right is a healthy normal hydra.

Check out our new publication in STOTEN ! Hydra oligactis show widespread vulnerability to tumours! In our lab, we use them as a model to understand how tumour progression affects the ecology of species and ecosystem functioning. Link: doi.org/10.1016/j.sc...

Turns out you can create XKCD style plots with R. Here I used the data of a very serious competition. The farthest distance for periwinkle spitting is 10.4 m and is held by Alain Jourden (France).

New study on how placentation is linked to #cancer risk in mammals. Placentation can be an invasive process with foetal cells invading maternal tissues, and we think that cancer cells may be able to use pathways responsible for that invasiveness to become more malignant (1/5) #SciSky

I am looking for one or two Australian Honours students for 2024. If you have interests in cancer, behavioural ecology, statistical modelling… come study with me to understand how cancer affects the ecology of species at Deakin University, Waurn Ponds campus in Victoria. #SciSky

Cool paper! Authors compared reviews from humans to reviews generated by ChatGPT. They observed that 57.4% of the users found GPT-4 generated feedback helpful/very helpful and 82.4% found it more beneficial than feedback from at least some human reviewers. #SciSky arxiv.org/pdf/2310.017...

On the right is a hydra with a tumour. It's a jellyfish like creature that lives in streams and ponds on the vegetation and rocks. The tumour alters their biology, changing their reproduction and they vulnerability to predation. Bellow on the left a healthy hydra and on the right one with a tumour.

Hello #HiSciSky, moving from the blue bird app. I am a scientist working at Deakin University and the French CNRS and focusing on how cancer is shaping the evolution of species, how humans are increasing the risk wildlife develop cancer, and what will be the ecological implications.
