Tell HN: Claude flags biology / biotech questions
I was reading the news about a capsule designed to deliver drugs via the GI tract, https://news.mit.edu/2024/bioinspired-capsule-can-pump-drugs-directly-walls-gi-tract-1120
And remembered prior reading that no system has ever been approved to deliver antigens via the GI tract. So I asked Claude Opus 4.5,
Have any antigen molecules ever been delivered via the digestive tract? Not to targets in the digestive track but elsewhere.

AFAICT, these restrictions didn't exist before. This extends to alien bio as well. I took a lengthy write-up from reddit about supposed alien physiology and asked Claude to summarize it for me. It was flagged. It went thru when I added a text about how it was speculative and not at all illegal.
