Irish DNA database … Хаджи-Мурат … Diapedesis, Extravasation 23rd of November, 2008 POST·MERIDIEM 10:45
We’re lucky enough to have Orna Tighe as one of our molecular medicine lecturers, and in the course of a lecture on methods of DNA and RNA analysis, she mentioned that the Republic of Ireland has a database of the DNA of everyone born in the country since 1970, stored at Temple Street Children’s Hospital. This came about because of two reasonable and not-very-shocking developments:
Because Australia is the most competent of the post-death-of-the-British-Empire states, this has come up in discussion (and in use) there, but it doesn’t look like they’ve actually resolved it. I would be shocked to my core if the Republic has digitised the Guthrie cards or otherwise made them workable in the direction of a police state, but the data are there, it would be constructive to work out exactly what we’re going to do with them.
Chadschi Murat, Leo Tolstoy, autorisierte Übertragung von August Scholz. This is a German translation of one of Tolstoy’s last novels, about a Chechen rebel leader (and eventual supporter of the Russians) in the mid-nineteenth century. I bought it because I had seen it recommended for its action and the plot, but I was most impressed (probably in the matter of someone who has never read War and Peace!) by Tolstoy’s interpretation of the motivation and thoughts of the protagonists. It can’t really give much insight into Chechnya today—as far as I can tell, the Chechens today are like the Basques today, totally comfortable in the culture of the wider nation, but believing themselves different despite that, whereas the Chechens of the 1850s were like the Bantu at the same point or the Highland Scots in the 1650s; culturally very different in practice, very ill-at-ease with the wider society they were coming into contact with. I liked it; I’m not sure I’d recommend it to many people, it would depend on their own interests; reading the beautiful Fraktur it was printed in (first time I’ve read a book in Fraktur) was enjoyable, though.
