Why did we use a hot dog roller for this? Did the ladybirds just enjoy it like a fairground ride? I explain here:

The work reports on abiotic factors influencing the parasite-host interactions of a microfungus & the invasive harlequin ladybird (#Harmonia axyridis).

That's a really weird one! I've been in Oldrich Nedved's lab for a while where they cross various strains of H. axy., but never seen this. You could shoot him an email about it, he might be interested.

🍄Microfungi on insects🍄
Fungi in the genus Hesperomyces are associated exclusively with ladybirds, visible as yellowish-greenish elongated balloons. We aim to map them in Europe and describe #newspecies. Join the #FunDive campaign! #Biodiversa fun-dive.eu/en/get-invol...

We made a few terabytes of images, which were reconstructed to create 3D images over the past couple of years by Michel back in Paris, resulting in this paper!

Doesn't it still look like he has the ~99 million year old wind blowing through his antennae?

Also, the synchrotron makes you look like the most sciency scientist ever.

The technique to create 3D image out of the microscopy is called micro-tomography, which was what we spent most our time doing. It is useful if you want to look at fragile fossil beetles trapped in amber! Michel Perreau, a French beetle and fossil expert, asked us to image them for him.

It's a massive complex with a big particle accelerator, which takes a long time to get around - many people had little mopeds or bikes. Particle accelerators produce extremely bright, focused, and tunable X-ray beams, which can be used to "see through" objects and reconstruct the details inside.

Back in 2022, @dhaelewa.bsky.social, Iva Njunjić (@taxonexpeditions.bsky.social), Warre van Caenegem and I went to the Synchrotron in Grenoble to image very small fossil beetles in very small pieces of amber. The resulting paper is now out! (With more to come)
