Chocolate (specifically cocoa butter) actually has multiple crystalographic forms (polymorphs), tempering is all about controlling which one (the hard shiny one is β(V)). But since it's crystals, we have the technology to resolve their stractures!

"#Nobel laureate Dorothy Crowfoot Hodgkin was born 116 years ago today. The legend among legends in #crystallography, she cracked the 27 atom structure of penicillin, and then the 181 atom structure of vitamin B12, and THEN the 788 atom structure of insulin. "

Two scientists.Two crystallographers.Both successful, but one died young after her most significant discovery was snatched from her, while the other lived to a ripe old age after a string of ground-breaking discoveries and a Nobel Prize. The former, Rosalind Franklin, is a household name. But the latter, in spite of the foundational importance of her work, has always remained on the fringe of our cultural perception: Dorothy Crowfoot Hodgkin (1910-1994). It is one of the truly frustrating thing

@sflorg #Structuralbiology is an important #basicresearch direction that aims to gain information about dynamics and interactions of #biological molecules. This research relies on high-tech, including #cryoelectronmicroscopy (EM), nuclear magnetic resonance (#NMR) spectroscopy, and X-ray #crystallography. Goals are a better understanding and e.g. the creation of #molecular #dynamicssimulations.

How do molecular machines work, interact and harmonize their activities to give rise to a fully functional cell? How are these processes regulated and how are they compromised in human disease? The Structural Biology Research Centre aims at answering these questions by gaining precise knowledge of the structure of macromolecules and macromolecular complexes, which is essential to understand how they function.
My friend and colleague recognised for his work!
Installation of tRNA modifications is key to protein synthesis.
In her presentation at #Biochemistry2026, Carine Tisné presented her group's in depth work on structural and functional studies to understand the underlying processes on the example of m1A.

The final STOE User Talk of the 2025/2026 season is coming!
Prof. Constantin Hoch (LMU Munich) will explore whether laboratory powder diffraction can be as accurate as synchrotron measurements, using amalgams as model systems. Practical insights for data quality and Rietveld refinements included.
