More #CT examples to close this January...and since #fungi are so beautiful seen from the outside, why don't you take a glance at their interior? CT scan of a mushroom (a destroying angel??? 100% wouldn't eat - correct, fungi people?) (1/2)

On the left, a cross-sectional image of a micro-CT scan of a sea urchin, showing the internal chamber of their skeleton, covered in spikes on the outside and with their buccal parts in the center. Four dashed lines (D E F G) are shown, which reflect the right four images. Those images are sequential sections of the buccal parts, showing the 5-fold symmetry and creating beautiful patterns.

The mummified remain of a snake, looking like a oval-shaoed wrap.
The micro-CT of the oval shaped wrap enclosing the mummified remains. The wrap is virtually cut in half to show the skeleton of the snake inside it.
#CTpost 🩻🐍
We can use #CT to gather info about the life and death of mummified remains! Here is an example of a snake! 🐍 By studying #μCT we know the snake was kept in poor condition before dying, leading to dehydration!

A close-up of a common fruit fly (Drosophila melanogaster) on a banana.
Longitudinal section of the Micro-CT of a common fruit fly (Drosophila melanogaster), shown white on black. The internal anatomy is visible. Thick thoracic muscles run from the back to the front of the thorax.

The 16th century Diss Heywood scroll, Norwich (UK). The scroll is severely charred and looks brownish with some parts highly blackened. A ruler and colour scale are shown around the scroll.
One slice of a Micro CT scan of a scroll showing a cross section of the scroll. The parchment rolled around itself is visible in white on a black background.
An ancient parchment scroll virtually unrolled from a micro CT scan. The ink is well visible from the background colour of the parchment.
#CTpost 🩻📜
This may be #μCT's greatest application! Once scanned, fragile ancient scrolls 📜 may be virtually unrolled and read! The ink and parchment absorb xrays differently depending on the ink composition, thus creating contrast! (1/2)

The four tiny and dark fragments of lunar rocks collected by the Apollo 11 and Apollo 17 mission. They are enclosed in a resin dome.
The 3D rendering of the materials distributed within one of the fragments, showing an abundant marix, with pores and ilmenite, a mineral relatively common on the moon.

A short-snouted seahorse on knotted wrack (algae). The seahorse is brown and it's holding onto the wrack by its tail. Photo by Hans Hillewaert.
The rendering of the scanned seahorse tail, showing the armored plates surrounding the vertebrae, with four interlocking plate elements constituting a section of the tail shown in different colours. Below, some theoretical models of the tail for simulation purposes.

The tail of a seahorse has a square section ⏹️, it's prehensile and covered in armored plates. If you #µCT scan it (rendering in right image), you'll see the plates interlock around the vertebrae. But why a square? (1/2) 🧪 #science #fish

Inside your cranium there are two large holes, one on each side of your nasal cavity 👃: the maxillary sinuses! We are not sure why they evolved, for warming air, biting mechanics, to make the cranium lighter or for other reasons (1/2) 🧪🏺
