LisaL Posted June 4, 2015 Report Share Posted June 4, 2015 (edited) She said human cells / metabolism cannot get hotter than 100 degrees C but I read about a boy (baby Rahul) who keeps catching fire due to his over active metabolism. Wasn't hard to miss considering this made headlines all over the world. Edited June 4, 2015 by LisaL Quote Link to comment Share on other sites More sharing options...
jerryan Posted June 4, 2015 Report Share Posted June 4, 2015 such stuff are deeply rooted into some religions. I have not heard such a thing in a muslim or christian religions. Quote Link to comment Share on other sites More sharing options...
pgrmdave Posted June 4, 2015 Report Share Posted June 4, 2015 No evidence of spontaneous combustion was found in his case. It's more likely that he was burned in the normal way. The only news sources that reported that he spontaneously combusted were low-quality sources that repeated the parents' story uncritically and without investigation.

CraigD Posted June 4, 2015 Report Share Posted June 4, 2015 [is My Biology Tutor Wrong?] She said human cells / metabolism cannot get hotter than 100 degrees CI guess you tutor reasoned that, because most cells, human or otherwise, are damaged so badly when the water in them approaches boiling temperature that they lose the ability to metabolize, we can safely say no organism’s metabolism can’t heat cells to 100 C. I think she’s correct. Most metabolic processes fail at much lower temperatures than this, so 100 C should be considered an upper limit. Human, for example, are seriously injured when their body temperature, measured in a usually way, such as orally, reaches about 55 C, and almost certainly die if it even briefly reaches 75 C. Some microorganism – thermophiles - can survive temperatures as great as 122 C. They don’t generate this heat metabolically, however, but rather thrive the water heated by hot springs or undersea hydrothermal vents. ... but I read about a boy (baby Rahul) who keeps catching fire due to his over active metabolism. Wasn't hard to miss considering this made headlines all over the world.I think you’re talking about the claims made by Rajeshwari Karnan that first one, then another, of her two infant children, caught fire, which we’ve discussed in the thread What Would Happen If The Sweat Gland Cells Produced A Large Amount Of Reactive Chemicals? I believe the consensus of the medical, social service, and law enforcement people involved in Karnan’s case is that she is scalding or burning her children to get money and attention. To the best of my knowledge, her children have not had any injuries since they were taken away from her, or been injured when they were not alone with her.

jerryan Posted June 5, 2015 Report Share Posted June 5, 2015 I love the explanation CraigD has given. But that stuff is just wied though Quote Link to comment Share on other sites More sharing options...
pgrmdave Posted June 5, 2015 Report Share Posted June 5, 2015 I love the explanation CraigD has given. But that stuff is just weird thoughPeople abusing their children often seems weird - it's one reason that some people will go to great lengths to try to not have to imagine a mother burning her own children.

fahrquad Posted December 23, 2015 Report Share Posted December 23, 2015 100`C is 212`F, or the boiling point of water. Human brain cells begin to die at 106`F. Paper burns at 451`F (hence the name of the book "Fahrenheit 451"). The crematoriums I have seen run at 1000`+F. Spontaneous human combustion is a myth.
