Plastic Red Blood Cells

03 May 2008 05:14 pm

William Saletan's thoughts on research into artificial blood cells:

The idea of having little plastic sacks pumped into your bloodstream sounds pretty freaky. We're talking about filling you with petroleum products in a way that challenges the meaning of "flesh and blood." For all I know, further animal or human testing may find unforeseen health risks from this kind of mixture, particularly at such a small scale and with such pervasion of the body. But if the technology turns out to be safe, it'll go a long way toward loosening our concept of ourselves as biological creatures.

Pardoning War Criminals
America doesn't pardon war criminals. It prosecutes and, in the past, has even executed them for the same techniques that Bush and Rumsfeld and Cheney endorsed.
The HIV Travel Ban Is Repealed
I've lived with this awful sense of insecurity, of fear of leaving the country, of visiting my family, of the lingering sense that my virus rendered me potentially deportable, that any roots I put down might be dug up suddenly one day - for fifteen years. The lifting of this threat - the sense that I now have a home I know will be secure for me and my husband - is indescribable.
Obama On Foreign Policy
What's interesting to me is how the speech is about much more than Iraq. It's about focusing on Pakistan, on energy independence, and on Iran. It's a speech that might have been given by the first president Bush.
Judge Judy Republicans
The problem with the working poor, as GNP has it, is not that they're capable of finding shopping bargains and living within their means. It's that they're sinking in a welter of family dysfunction and economic distress - and end up like the plaintiffs on Judge Judy.
Staying
Occupations are like government programs. Once instituted, it seems they can never be abolished.
