The cloned piglets PPL introduced to the world last week were created in just this way, though for this first experiment in pig replication, the scientists left the sugar genes intact. "We wanted to work with pristine cells to make sure our cloning technique would indeed work," says Ayares. Now...
Despite this recent success, PPL is not likely to be setting up its organ shop anytime soon. Knocking out the key sugar gene solves only the problem of short-term rejection. Long-term rejection, caused by blood coagulating around the new organ, requires that researchers re-engineer an entirely different...
Do flies sleep? after prodding and tapping fruit flies, measuring their activity with ultrasound and infrared detectors, blasting them with sound waves and monitoring their genes, researchers at the Neurosciences Institute in San Diego have come to a definitive conclusion: the flies actually doze off in slumber patterns that are...
Perhaps most significant, many of the fly genes that turn off during sleep and on when the insects are active proved to be identical to those that regulate mammalian slumber. That means researchers can use flies to test potential drugs and genetic treatments for aiding sleep and preventing drowsiness, rather...
And Dolly begat Millie, Christa, Alexis, Carrel and Dotcom... The British company that shocked the world by producing the first cloned sheep announced Tuesday that it had produced five cloned piglets - and not only that, certain genes had been "knocked out" of some organ cells of the above-named piglets...
