Whether you think limiting student visas to 4 years is a good or bad thing, please comment. Be heard.

Dr. Kat Napaaqtuk❄️ @napaaqtuk.bsky.social · 11d

Comment period ends on Monday for a proposed rule change that would terminate student visas after 4 years. It also puts limits on exchange visitors and reps of foreign media, and shortens the length of time at the end of the visa from 60 days to 30 days.

Image credit: DALL-E. Not long ago I wouldn't have imagined my lab making our own nanobodies, the same way that I wouldn't have imagined myself making any image worth posting. Grateful to stand on the shoulders of so many protein designers.

t.co/UmbCz8ajMD Spearheaded by Santi, it’s a tremendous team effort with John, Claudia, Haoyu, Talal, and Xiaowei, and a close collaboration between @brianhie.bsky.social’s and my labs. Can’t wait to see what binders everyone will design with it!

Xiaojing Gao @synbiogaolab.bsky.social · 14d

Having often dealt with the frustration of binder-limited projects, we sought a more accessible source for nanobodies than yeast display or llama. Here we introduce Germinal, computationally designing antibody-like binders with such a hit rate that only tens need to be screened for each target.

We previously built programmable RNA sensors based on editing by housekeeping ADAR enzymes. But they can't sense arbitrary sequences due to design constraints (analogous to PAM for CRISPR). With our new "modulADAR", we overcome that constraint by leveraging ADAR's modularity.

Thank you, Scott! We certainly hope we could go that far...

Thank you, Sai!

More importantly, for diseases that have to be addressed using nucleic acid therapies, such as some recalcitrant cancers, RNA offers the safer option than the more conventional DNA vectors, because RNA is less likely to leave permanent marks in the patients' cells.

Xiaojing Gao @synbiogaolab.bsky.social · Apr 3

If I might clumsily point out the economic impact: our project germinated from Impetus Grants @norngroup.bsky.social and an NIH trailblazer grant that add up to ~$0.5M, and now our company supports a dozen employees.

Grateful for the recognition and for my team's dedication. When I wrote it in Oct, I didn't anticipate that the title would feel defiant. The original draft even had a now quaint reference to "the comparative comfort of the ivory tower", which was wisely removed.

We were inspired by pioneering humanization works from Roybal and @chembiobryan.bsky.social labs. We especially stood on the shoulders of @mokhalil.bsky.social lab's synZiFTRs.

As is typical of such works, we built on what came before us, esp. the ZF programming model developed by @hsnajafabadi.bsky.social et al, and the protein language model-guided optimization demonstrated by @brianhie.bsky.social et al and others.

So we beat on. Gene/cell therapies would benefit many patients, but often use proteins that could be recognized as non-self by our immune system and cause problems. We combine algorithms to build proteins that are therapeutically relevant and can masquerade as our own parts doi.org/10.1101/2025...
