Brave New World Watch

24 Mar 2008 02:26 pm

A tissue-engineering group has created functional blood vessels and cardiac tissue by "using a 'printer' that dispenses cells instead of ink":

What makes this work different from that done in most other tissue-engineering labs is that Forgacs's team does everything without a scaffold — they don't start with an object shaped like the tissue or organ they are aiming to create, but instead plan to print the whole thing from scratch, from the vasculature up. This should make it easier to print any type of organ, they say, as they don't have to develop different scaffolds for each tissue type.

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The HIV Travel Ban Is Repealed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.
