Hope you had a good valentine's Day (although St Dwynwen's Day 🏴󠁧󠁢󠁷󠁬󠁳󠁿 is really where it's at)
From and X-ray machine, with love ♥️

Some blue woodlice for #BlueBugs #BlueMonday

Infected with iridovirus, which makes them appear blue. More info on what's going on in the video

Ayyy, TJ, you're here on Bluesky too. Is there a tomography community yet, I wonder

Favourite bit of any x-ray conf is the weird sample setup chats!

For those who have joined semi-recently - here is a starter pack of Materials Scientists & Engineers.

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

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

An oldie but a goodie, and a useful demonstration of the power of 3D X-ray microCT for generating real-life geometries and morphologies for finite element analysis that I can roll out for both Christmas and Thanksgiving!

The complex network of calcareous tunnels left by colonising tube worms on this whelk shell.

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

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 🧪

Cheers Chris. I'm just working out what to do and how to do things. Surprisingly different but also same :-/

*Crawls up to the BlueSky door*
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?
