Sick Kids Researchers Confirm That Cancer Stem Cells Initiate And Grow Researchers at The Hospital for Sick Children (Sick Kids) and the University of Toronto (U of T) have confirmed that childhood and adult brain tumours originate from cancer stem cells and that these stem cells fuel and maintain tumour growth.

Sweet Solution To Energy Production Sugarcane biomass, a significant waste product from sugar production, could be a renewable energy source for electricity production, according to researchers. Could The Exploitation Of Space Solve The Earth's Environmental Crises Could the industrialization of space could help solve environmental problems here on earth? Ecologism offers a solution by emphasizing the need for major socioeconomic reform aimed at a post-industrial era. Environmentalism, in contrast, focuses on the preservation, restoration, and improvement of the natural environment within the present framework. Now a pundit suggests that there is a third approach to sustainable development that has until now been excluded from the agenda - namely a large-scale industrial expansion into space.

[Scary] Pregnant woman says 'maternal instinct' helped her kill attack FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind."

The key is to weed out potentially destructive forms of iron that generate harmful free radicals while leaving benign forms of iron alone to carry out vital functions in the body.
