I am a bit late for Ides of March, but let's speak about stabbing mineralogy.
Julius Caesar was stabbed using pugiones - type of daggers.
Not mineral was name after a pugio (yet), but there is a mineral Gladiusite named after gladius.

Gladiusite
Note: Gladiusite contains both Fe3+ and Fe2+ in the (ideal) ratio of 2:1. The colour of the type material is described as "dark green, almost black". The ...

I accidentally made a Halloween decoration - a TA asked to print a cyclodextrin with a guest molecule for school activities. But the pumpkin style was accidental, I picked colours randomly.

Had a very long social media break after the last #SynchrotronMugMadness and the bird site's decent into horror.

So hello bluesky, I'm a staff structural biologist helping @imperiallifesci.bsky.social solve protein structures with #crystallography and #CryoEM.

Please enjoy these protein crystals 💎

I'll soon share a nice #singlecrystal #MOF #totalscattering work I've been hatching for a while with some great scientists... but since it's taking a while for seeing it online I thought I'd treat you all with an artistic collage of the data 😏 ...stay tuned! #BraggYourPattern #crystallography
Seven single crystal diffuse scattering patterns are arranged in an hexagonal grid (experimental data): one pattern in the middle, six surrounding it.

No contest for #crystallography for today's #MinCup26 battle - we have 'I don't know my crystal structure' #Chrysocolla vs 'First crystal structure EVER determined' of #Halite. So though it is a boring structure - #Halite gets my vote today
Image representing the crystal structure of halite. Yellow spheres represent sodium atoms, green spheres represent chlorine atoms. The representation is drawn in VESTA from entry #641 in the American mineralogist database.

Diamond Cubic by elkement 2026. Crystal structure of diamond, colored pencils drawing (construction) on black paper. Two face-centered cubic lattices, shifted by one fourth of the space diagonals of one of the cubes. The atoms on the shifted positions become the centers of tetrahedrons formed by four atoms of the unshifted part. Showing the tetrahedrons (edges highlighted in yellow, orange, and red), and the two "sub-lattices" have blue and green atoms, respectively.

Casual reminder that what many consider 'information' from #crystallography is actually a model. That is why structure factors must *always* be published, so that reviewers and anyone can see what lies behind the model. Without them, crystal structures are nothing more than 'pictures' in 3D.
The difference between a model and the underlying crystallographic information is shown for the disordered MOF published in this paper: https://pubs.acs.org/doi/10.1021/jacs.2c13731. The model shows a ball&stick atomic structure, whereas the information (electron density calculated from structure factors) is displayed as density map with coloured contours.

Tiling of tilted squares in black, yellow, blue and grey. The empty spaces, with shape of horizontally and vertically oriented rhombuses, are reminiscent of the orthorhombic structure of CsPbBr3 perovskite.

Great work highlighting how important it is to carry out experimental structure determination instead relying on AlphaFold predictions. #crystallography #structure #biology #chemistry

AlphaFold predictions are valuable hypotheses and accelerate but do not replace experimental structure determination - Nature Methods
An analysis of AlphaFold protein structure predictions shows that while in many cases the predictions are highly accurate, there are also many instances where the predicted structures or parts of pred...
