Happy St. David’s day

a scan of a frog shown from the top with all of its tiny bones showing and some soft tissue in its abdomen in purple
four views of a thick lizard specimen with rows of angular scales on its body shown in golden and each view showing either bones, circulatory, nervous system or digestive oranges in bright colors
the skeleton and some scales of a large almond shaped fish are scanned in dark blue with some fin spines highlighted in rainbow of colors

Some blue woodlice for #BlueBugs #BlueMonday
Infected with iridovirus, which makes them appear blue. More info on what's going on in the video
Amazing!!! Just clicked 'follow all'!

Favourite bit of any x-ray conf is the weird sample setup chats!
Classic Swansea dampness here 😞

I am happy to add folks if you just reply to a thread where I mention it.

Cactus spines and a polystyrene ball ojna green cutting mat

First day back in the lab & returning to a very tricky sample for x-ray imaging.
*Through gritted teeth* it just keeps ******* moving!
So today I made a little cage from cactus spines on top of a small polystyrene ball to keep the head of a tiiiny deceased beetle stationary in ethanol during scans
It's happening! #Xrays

Collected on the Swansea Uni campus beach as part of an undergrad materials science bioprospecting class then X-ray imaged at the lab 100 yards from the shoreline
This kinda sums up what I do as a researcher working on materials ranging from ocean organisms to space alloys, volcanoes to meteorites, jet engines to insects. With a leaning towards bioinspiration/biomimicry.
This is me in VR crawling through the coiled proboscis of a moth we imaged using X-rays
Haha ok thanks Ben 🤣
I’m noob’ing my way through Bluesky at the mo!
Similar to others, there are some cheapish all in one options: amzn.eu/d/h44IEOS
But if they already have a good microscope with optics, a slide-in camera or a phone mount (as others have suggested) may be better. Phone cameras a more generally better than consumer microscope cameras
I'm looking to grow some connectivity for materials scientists & engineers on BlueSky - if you identify in this grouping, I'd be happy to add you to this starter pack 🧪

Please let me in, out here has been completely festooned with weak-ass billionaire shit-memes, and filled with fawning bin people.
Are, are there scientists in there?
