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)

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.

The Role of Selection for Function in Aging and Chronic Diseases: A Novel Evolutionary Perspective
This conceptual diagram shows how aging alters selection within the body: strong early-life Darwinian selection prevents aberrant structures, while weakened selective pressure in later life allows pe...

Towards a more robust comparative oncology: a Bayesian reanalysis of Peto’s paradox and discussion of comparative cancer risk studies in vertebrates | Royal Society Open Science
The multistage carcinogenesis model predicts that cancer risk should increase with
body size and longevity owing to greater cell numbers and divisions, which provide
more opportunities for mutations. ...

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.

A nice short paper arguing that a small significant trend between body size and cancer risk is not enough to disprove Peto's paradox. I agree with the author we need null models when we test the effect of a risk factor on cancer in comparative studies

In this study, we found that transmissible tumours, much like some parasites, can change the way their host looks and behaves to benefit themselves.

Hey #SciSky, what are good alternatives to BLAST to find a given gene in a published unannotated genome. Like when the genome is provided at the contig or scaffold level for example? Something that runs with R or Python would be cool, but open to alternatives.

Can individuals with tumours serve as potential vectors for symbiont spread in an ecosystem? We found that lab freshwater hydra with tumours caused their commensal ciliates to spill over onto neighbouring hydra from the same or different species.

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).
