I'll be honest, my understanding of the procedure is that it's just building on techniques that have been around for decades - the first somatic cell cloning was in the fifties, after all. You take an egg cell from a woman without mitochondrial diseases, remove the nucleus, and pop in the nucleus from either the egg… » 2/03/15 11:21am 2/03/15 11:21am

More hands-on experiments. You can lecture or show diagrams until you're blue in the face, but the parts of high school science I remember best are the demonstrations and experiments, from using small catapults in physics to setting things on fire in chem to blood typing in bio. Why yes, this will require more… » 11/10/14 7:26am 11/10/14 7:26am

I just finished reading The Ghost Map and am profoundly reminded of Edwin Chadwick's claims that dumping sewage into the Thames would be good for fish and field, because after all farmers used manure to nourish their fields. Logically, the argument went, in repeating the experiment on a larger scale London's waste… » 10/06/14 12:03pm 10/06/14 12:03pm
