Playing around with quantum-styled math on trivial biological problems before tackling the really hard questions. Initial signs are good, with the math behaving as expected. Next leg would be using a non-trivial dataset like missense variants.

Within Tagetes lemmonii, (Lemmon’s marigold) are defence molecules called thiophenes which become highly toxic when exposed to sunlight, damaging pests at the cellular level. An elegant example of how plants weaponize light to survive.

Tagetes lemmonii, also known as Lemmon’s marigold (or mountain marigold according to Google's Brisbane result) is shown against a blurred background (bokeh).

If you do deep evolutionary analysis - structure-aware characters can help. To ensure correct alignments - give it a try: biosig.lab.uq.edu.au/structome_al...

If you would like any features added, drop a message and will give it a shot.

🕰️ Let these structure-aware sequence alignments reveal a distant past that amino acid sequences alone couldn’t reach.

Using pairwise structure-aware character substitution scores across your proteins, the app computes per-column confidence, maps it to B-factors, and visualizes it in Mol*. You can spot conserved cores.

But structure-aware alignments can mislead if divergent folds cause misalignments. That’s where Structome-AlignViewer comes in — it helps you evaluate how reliable each alignment column is, and where structural consistency holds up.

What are structure-aware characters?

Structure-aware characters describe 3D conformation. Each residue gets a label (by Foldseek) based on its spatial context — enabling compact, alignment-ready strings from protein structures.

In a talk today thinking that science isn’t just a collection of facts it’s a method and sometimes, a philosophical tightrope.

Emeritus Professor Ross Bernard at #UQ exploring how science proceeds - via falsifiability. Not everyone agrees but a conversation worth having.

#DecodingEvolution The Molecular Story of Life’s Transformations

#Evolution is often seen in grand transformations dinosaurs into birds, fish onto land. Uncover how tiny changes drive life’s biggest adaptations, revealing evolution’s true blueprint.

Oldest reference I’ve ever seen while reviewing — 1667, Antonie van Leeuwenhoek.

From the first observation of bacteria under a handcrafted microscope to modern phylogenetics. Science stands on the shoulders of giants — even from 400 years ago.

“Bringing Quantum to Life: How Quantum technologies may shape the future of society”.

Exciting times ahead as quantum algorithm unravel mysteries of life.

For better analysis of drug binding profiles - we integrated ligand related information as well. Would love to hear thoughts from the community! Any suggestions for improvement on this database while we work on the meta predictor?

Mutation impact isn’t just about sequence—it’s about where the mutation occurs in 3D space. #MissenseViewer links missense effect predictions to protein structures, helping extract structural features that can improve predictive models and deepen our understanding of mutation effects.

#AI #science
proteinmechanic.bsky.social
Each predictor has strengths and weaknesses—some overpredict #pathogenicity, others miss functionally critical sites. A meta-predictor that synergizes these methods could help improve accuracy. #MissenseViewer is a first step in enabling this by providing comparative insights across predictors.

#AI

Missense mutations impact protein function, but no single predictor is perfect. MissenseViewer integrates AlphaMissense, ESM1b, and VESPA predictions, mapping them onto protein structures to provide a richer, more interpretable view of mutation effects.
