Co-founder and CEO at OneAngstrom | I post about molecular design and #SAMSON, the integrative molecular design platform |

[Stephane Redon @StephaneRedon]

Big update from OneAngstrom: SAMSON 2026 R1 is here! This release brings powerful new capabilities: the Path Analyzer, the Strain Explorer, and integration of Meta’s UMA force fields - plus more improvements across the platform.

We’re excited to keep pushing SAMSON forward for the molecular modeling community!

Racks for the 32-tooth gear. There is a bushing on the other side as well, but it is a little too large. Making it smaller would be an excellent intro project for someone. https://t.co/Hba6jgBgLe

It's a pretty straightforward leap from this TX crossover to stapling together origami. Download here https://t.co/yiins74C5A

DAO crossover. Same as the double anti-parallel even (DAE) but now with an odd number of half-turns between crossovers. Got 10 crossovers to get though and then we'll put them together for more complex stuff. https://t.co/4LJtiX3I09

Let's soften things up some from diamond. I'm starting a new series and part repository for DNA structures, machines, and origami. DNA is what I worked on before I got into diamond machines. Here is the first tutorial. https://t.co/O12LjFVAO5

Good diamondoid-machine designer rule of thumb: adding 6 rings around the circumference increases the diameter by 0.5 nm. Download here https://t.co/mRRDPi3JCJ

On April 30, I’ll be hosting a webinar to introduce SAMSON 2026 - the new release of our platform for molecular modeling and simulation.

This version brings major improvements across SAMSON, including new tools to help researchers move faster from structure to insight. During the webinar, I’ll show in particular how to:

✅ use the new Path Analyzer to analyze paths and molecular dynamics trajectories and generate advanced plots in just a few clicks
✅ use UMA Force Fields in interactive simulations
✅ use the new Strain Explorer to analyze ligand poses

If you work in molecular design, computational chemistry, structural biology, materials science, or related fields, this session will give you a concrete look at what’s new and how it can accelerate your workflows.

If you’d like to follow along during the webinar, you can create a free account on SAMSON Connect and install SAMSON beforehand.

Excited to share what we’ve been building!

Just finished uploading 29 basic structural diamondback parts to #SAMSON Connect. If you build anything with them, please let me know so I can be excited for us. https://t.co/d7vBiGP99p #molecularmodeling
