Resurrecting Mammoths

by Justin

Hold on to your butts. University of Manitoba professor Kevin Campbell has ushered in an era of “virtual scientific time travel” by recreating the hemoglobin of the long extinct woolly mammoth. And if that immediately reminds you of Jurassic Park, it’s only going to get more uncanny:

Campbell and his team were able to extract DNA from three woolly mammoths preserved in the Siberian permafrost. And because mammoths are so similar to elephants, he was able to modify living elephant DNA, letter by letter, to make working mammoth genes. He inserted those genes into e. coli bacteria.

The Guardian covered it in an online gallery showcasing a good range of artistic skill and childlike insanity. Read the rest of this entry »

Iran and the Bomb

by Justin

When the Goldman Sachs trial first claimed the headlines I wrote something about it being an opportunity for the Obama administration to bill itself as the hero to the GS villain. The parts of me that want the Democrats to do well in November would love for Obama to generate some sort of unassailable momentum. Financial reform, as it turns out, hasn’t offered the populist rallying cry some may have hoped – even with the SEC charges and criminal probe.

So at what should the administration aim its cannon? Read the rest of this entry »
