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)

Species named after celebrities receive more attention than others. Big effect for invertebrates!

🚨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.

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.

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.

A happy native Australian planaria culture I maintain in my lab.

Little freshwater planarian sampled in an urban pond in Australia. This one is an invasive species from North America.

Our new opinion paper on evolutionary mismatches in #aquaculture systems and how to address them to maintain good production is now published in Reviews in Aquaculture. A collaboration between the CANECEV and NuSea.Lab at Deakin University

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.

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

Sneak peak into an Australian freshwater hydra culture. We use those little jellyfish creatures to study the effect of cancer on ecosystems #SciSky

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.
