Comment Waste heat recovery (Score 4, Interesting) 79

by Rauser (#65003309) Attached to: Microsoft Unveils Zero-Water Data Centers To Reduce AI Climate Impact
Current water-cooling typically dumps the waste heat either to the atmosphere (via evaporation of water) or directly into a body of water such as a lake, river, ocean or holding ponds. This is true of most large heat generating facilities such as power plants, as well as data center. Having a closed loop secondary cooling circuit opens up options to recover the heat for other uses like municipal heating or cogeneration of power. Whether Microsoft is interested or positioned to do this is another question.

Child Receives Trachea Grown From Own Stem Cells 103

Posted by samzenpus from the just-add-oxygen dept.
kkleiner writes "Doctors at the Great Ormond Street Hospital (GOSH) along with colleagues at the University College London, the Royal Free Hospital, and Careggi University Hospital in Florence have successfully transplanted a trachea into a 10 year old boy using his own stem cells. A donor trachea was taken, stripped of its cells into a collagen-like scaffold, and then infused with the boy's stem cells. The trachea was surgically placed into the boy and allowed to develop in place. Because his own cells were used, there was little to no risk of rejection. This was the first time a child had received such a stem cell augmented transplant and the first time that a complete trachea had been used."
