Biopharma companies and CEOs are keeping their heads down at their own peril. They should speak up about what’s happening to the NIH and other science agencies before it’s too late.

Silence gives consent. And no one should consent to this.

Protein backbone diffusion models consistently undersample catalytically important motifs, and oversample idealized helices, raising questions about the appropriateness of these methods in designing starting points for enzyme design & evolution. From www.biorxiv.org/content/10.1...
Protein structure embeddings reveal undersampled and de novo structure space. (B) First two principal components of mean-pooled ESM3 embeddings colored by helix content determined by DSSP. The indicated dashed guide lines denote visual boundaries of native structure space not sampled (Undersampled) and novel regions of protein structure for this space only observed in samples but not in native structures (De novo). (C) Rasterized visualization of panel B with 16 equally spaced grid squares in each principal component axis. A representative structure from each grid was chosen at random. Empty grid squares indicate the absence of any structure in the enclosed region. De novo alpha helices are shaded along the lower-right diagonal and the structures from CATH which do not have corresponding structures in the samples are shaded along the left and top rims. The structures are displayed in CATH raster plot are given in the Supplementary Information.

Analysis of the oldest-known genomes from early modern humans in Europe, who lived around 45,000 years ago, helps to provide a more precise date for when Neanderthals and modern humans mixed, according to research published in Nature. https://go.nature.com/3ZR8Kh1 🧪 🏺
This is figure 1, which shows the geographical distribution of modern human specimens older than 40 ky that produced genome wide data

new preprint on chemical synthesis ML models

- showing how to combine multiple models in a principled way
- modern Transformers + GNN to featurize chemical reaction:
- new insights in where the models shine
+ bonus: find the quirky named reaction!

Feedback welcome!

Chimera: Accurate retrosynthesis prediction by ensembling models with diverse inductive biases
Planning and conducting chemical syntheses remains a major bottleneck in the discovery of functional small molecules, and prevents fully leveraging generative AI for molecular inverse design. While ea...

We keep getting messages saying climate change is a hoax and the world is flat. Is it 2024?!

The first paper from the Small Molecule Steering Committee at Polaris introduced practical guidelines for method comparison in ML-driven drug discovery.

We'll be discussing this live on Dec 5th from 11 - 12 PM ET.

More generally (not for HIV protease case specifically) I would propose to consider 4-5 options:

What to do with waters in drug discovery is one of the most important decisions that drug designers need to make. What would you do with the FLAP water on HIV protease? Address or Replace?
