Citrus CT work.
And we published a virtual issue, Fruit in Focus. Check out the Editorial by @zoemig, @phylofeast, and @ewarschefsky 👇

ALT Depiction of a citrus scanning, data acquisition and image processing pipeline.
Is this some weird alien landscape? The surface of an asteroid? Nope, this is a CT scan of a Brazil nut. I love how the crevasses in the nut really show in the scan.
CT scan of an almond. The fibrous material in the shell shows up very nicely. There is also a double nut in this almond. Almonds are not true nuts, but drupes.
CT scan of a hazelnut, one of my favorite nuts. Much to my disappointment, this nut failed to develop.
In the language of flowers, a dark crimson rose is a sign of mourning. Classes may have restarted, but we are still mourning. The three lives needlessly cut short. Our sense of normalcy. The students who may never come back.
ALT CT scan of a rose, false colored dark crimson on a background that is green on the top and then fades to white on the bottom.
A CT scan of a nut that out of its shell looks very similar to a walnut, the pecan. Inside their shells, there is no mistaking a walnut and a pecan.
I just finished spending a large amount of time looking at walnuts scanned via CT for a project with Pat Brown at UC Davis. Although this walnut is a higher resolution scan than the ones I was looking at and I got to eat this one after it was scanned.
CT scan of a sprouting potato. In the scan you can see where the new sprouts and roots growing along with how the potato is shrinking as resources are being used to feed the new growth.
Tried scanning a pair of sunglasses for fun and this was the result when I tried to see the plastic and metal at the same time. Lots of x-rays reflecting of the surfaces. Looks pretty cool, though.
What thresholded for just the metal frames looks like for comparison.

On Friday, Nov. 4, a sale funding the MSU Horticulture Gardens will be held at the Plant and Soil Sciences building at 1066 Bogue St., from 8 a.m. to 4 p.m. statenews.com/article/2022/1…
Found a leaf with galls on the sidewalk and CT scanned it. You can see on the video of the scan how the galls grew from the underside of the leaf. What the objects next to the gall are? I really do not know.

Citrus fruits come in a huge array of sizes and shapes and are intrinsically connected to human health and culture.
Modelling fruit shape and oil gland distribution can provide insights into fruit development and domestication 🍋

New paper from our scans of citrus fruits 🍊🍋. Thanks so much to @danelleseymour for sending us citrus to scan.

Super cool gall I found and scanned in the CT. This oak now has leaves that do not look like normal oak leaves, but sepals of a flower. All extending from the gall, like a flower.
Is this some weird rotating alien brain? No, just the flesh of a walnut rotating as isolated from a CT scan of the entire walnut.
A new paper using CT images of soil obtained using our instrument.

CT of a unknown gall on an oak. On the scan you can see the veins of the gall converging on the growing insect to provide nutrients.
Scanning a lot of soils lately, but this small (2.5 cm) core is very strange. There is a shift of either texture or compaction in the middle of this particular core, which is strange for the soil texture and the sample site. From research with @JamesOSoilivan .
