1/ Ever needed to annotate TEs in a fungal genome, but didn't know where to start?

We have released #MycoMobilome, a community-focused non-redundant database of transposable element consensus sequences for the fungal kingdom, constructed from >4,000 fungal genomes!

STEPS To It Announcing a new program, called STEPS, to simulate the dynamics of evolving microbial populations.

Excited to share new #program, STEPS, which can simulate #dynamics of the E. coli Long-Term Evolution Experiment (#LTEE) or other microbes in serial transfer regime.

STEPS developed by @devinmlake.bsky.social, Zachary Matson, Minako Izutsu, and me.

Tn7 family transposons that include all of the guide RNA-directed transposons (CAST) are common in bacteria. We now find diverse representatives across archaea, with many in the Asgard group. Reviving an Asgard element confirmed the exciting behaviors of the family #MicroSky #TESky

We made structural predictions of representatives of each #PHROG from #phage genomes, and put the whole lot online. You can browse through montages or go to your favourite phrog directly and download its PDB.

A @csisingapore.bsky.social team showed D-I-Tasser can outperform AlphaFold2/3, elevating high-accuracy protein structure & function predictions. We wonder if this moves us closer to resolving protein–protein complex structure prediction? @natbiotech.nature.com

Fig. 3 from the paper, showing that model performance levels off around 300M parameters and ESM C variants tend to outperform the other available protein language models.

Figure 5 from the paper, showing a wide range of model performance across datasets, with R^2 values ranging from 0.1 to 0.8. Only a small fraction of this variation is explained by either dataset size or protein length.

Now published: Systematic comparison of protein language models for transfer learning.

Key points:
- You don't need gigantic models. The two smaller ESM C variants work great.
- There is huge variability in performance across datasets. We have no idea why.

An assessment of DNA language models concludes:
◼️ They do not offer compelling gains over baseline models

Their performance is inconsistent and requires much more compute.
