Successful Stem Cell Replacement of Windpipe 116

thepacketmaster writes "In what is being hailed as a medical milestone, CNN reports a woman suffering from long-term tuberculosis had her lower trachea and bronchial tube replaced by tissue grown from her own stem cells. A team from the universities of Barcelona, Spain; Bristol, England; and Padua and Milan, Italy, decided to go ahead with the surgery instead of having to remove her left lung. The operation, reported Wednesday in the British medical journal The Lancet, has been hailed as a major leap for medicine that could offer new hope for patients suffering from serious illness."

'These are truly massive cyclones, hundreds of times stronger than the most giant hurricanes on Earth,' said one mission scientist. Cumulus clouds twirl around the vortices, betraying the presence of giant thunderstorms lurking beneath. But the storms do not disturb the bizarre hexagonal cloud formation previously reported."
