...common feature he saw in fast-growing tumors: unlike healthy cells, which generate energy by metabolizing sugar in their mitochondria, cancer cells appeared to fuel themselves exclusively through glycolysis, a less-efficient means of creating energy through the fermentation of sugar in the cytoplasm. Warburg believed that this metabolic switch was the primary cause of cancer, a theory that he strove, unsuccessfully, to establish until his death...
...therapeutically exploited. The theory is simple: If most aggressive cancers rely on the fermentation of sugar for growing and dividing, then take away the sugar and they should stop spreading. Meanwhile, normal body and brain cells should be able to handle the sugar starvation; they can switch to generating energy from fatty molecules called ketone bodies - the body's main source of energy on a fat-rich diet - an ability that some or most fast-growing and invasive cancers seem to lack...
...apartment less than half a mile from the Yard. The UC leader and former Quincy House resident, who stayed in the apartment while doing coursework and attending to UC business this summer, cited a desire to live with two of his best friends as the reason for making the switch. In an interview yesterday, he said that he did not believe the move would affect his work with the student government, and that he in no way felt he was distancing himself from the campus residents who elected him last fall. “I was aware that...

The sleep/wake switch is in the brainstem, which helps control the body's most basic functions and stays active for longer than the higher brain in cardiac arrest. "It's likely that the transition to brain death is, in fact, gradual," says Mahowald, "and NDEs occur during this transition." As for people reporting accurately on events that went on around them while they were apparently unconscious, Nelson says "they may be seemingly out of it but still processing in a very...
