A facile chemical strategy to synthesize precise AAV-protein conjugates for targeted gene delivery
cell.com
A strategy to site-specifically attach recombinant proteins onto AAV capsids was developed using noncanonical amino acid mutagenesis and bioorthogonal conjugation reactions. An optimized AAV-anti-H...

1/ After residency at Mass General Hospital, I reported to Atlanta to meet my fellow CDC Epidemic Intelligence Service Officers. I have never felt so intimidated by my peers The best and the brightest, they were star clinicians, had served in disaster zones; MD/PhDs and MSF.

Thrilled (and relieved) to finally have this review by Arianna, Zeyi, and Kaitlyn out! Everything you've ever wanted to know about genetic code expansion in mammalian cells!
pubs.acs.org
Genetic code expansion (GCE) in mammalian cells has emerged as a powerful technology for investigating and engineering protein function. This method allows for the precise incorporation of a rapidly...

It’s been a tough few weeks. My 10yo daughter was diagnosed with a very rare, aggressive cancer called interdigitating dendritic cell sarcoma (IDCS). I’m reaching out to identify clinicians/patients who have encountered pediatric IDCS, indeterminate dendritic cell histiocytosis

Last year, $9B of the $35B that the National Institutes of Health (NIH) granted for research was used for administrative overhead, what is known as “indirect costs.” Today, NIH lowered the maximum indirect cost rate research institutions can charge the government to 15%, above
