    Background on this question: CRISPR-Cas is a naturally occurring process in bacteria that is used to adapt to viral attacks. We've coopted the system for use in mammals. As far as …

    > I would deal with this by deciding how many cells I want to kill each day Yes, this is an approach. This starts to exceed my understanding of the problems the teams are facing - …

    > How much overall has this costed you? For this project, seed capital low six figures. I am collaborating with family and friends, non-profits, and using doubling mechanisms avail…

    > I don't think that more than sloppy accuracy is acceptable for any gene therapy Valid critiques of Cas12a2 must acknowledge the mechanistic differences between Cas9 and Cas12a2. …

    > Are there any plans to move to in vivo? Yes! That's the next step. There wasn't a mouse model for my variant so they're building that, too. But in vivo testing should be underway…

    Done! Wrote a bit more in a comment above. Thank you for the interest.

    Thank you. I want to make sure you see the comment above - I think it was your comment that nudged me into writing it :) Happy to answer any other questions, here or over email (in…

    > So how does Cas12a2 mitigate off-target effects? Others in this thread may be able to give a better analogy, but I'll try: Cas9 is like open heart surgery on millions of cells al…

    I haven't written about it publicly, but I can elaborate here. I don't mind answering further questions about it even if you believe they'd make me uncomfortable - they won't. I've…

    There are two major problems, delivery is one of them. Collateral damage of mass cell destruction leading to systemic inflammation is the other. The approach I'm reviewing now uses…

    You're correct about CRISPR Cas9. The off-target affects are difficult to manage. The paper describes Cas12a2. This is a different mechanism with discovery origins in - of all thin…

    The cost of cartridges are comparable to optical disks. However, LTO drives are non-trivial in terms of both mechanical complexity and cost. I can toss an optical tray into the rec…

    You would think they'd have lifetime appointments as other federal courts do, but it's important to note FISC (and its review process) isn't the final stop on some Orwellian and di…

    I question your assertion it is not an Article III [1] court. In fact, I think you are either wildly misinformed or being intentionally misleading. The FISA court of 11 judges is a…

    The argument for a persons "right to die" may hold up to some degree. However, I believe the spirit of that sort of protection applies to those who are terminally ill. The idea bei…

    Slightly off-topic. Years ago when I was working at a small ISP in Columbia, SC I had lunch with Austin Meyer. He came in to upload the latest release of X-Plane to his FTP servers…

    It isn't a problem if you're speaking specifically about Cloudant. They co-locate clusters next to your app as best they can (as Mike has mentioned elsewhere). That makes the netwo…
