Approximately 100 mice were killed because of a clerical error at the Medical School on Tuesday, according to the Harvard University Police Department (HUPD...
...mice were part of an experiment that belonged to a Medical School researcher who has the same name as a second researcher...
...medication that is essentially lifelong and, in the view that many physicians are coming to accept, this is the model that will be needed for obesity. At the same time, scientists are beginning to unravel the biological basis of overweight. Molecular biologists, for example, have identified five genes in mice that control food metabolism and that, if damaged, can lead to chubby rodents. In humans, physiologists are beginning to track the multiple hormones that conspire to keep fat people fat and thin people thin. And as Redux and fen/phen demonstrate, neurologists are beginning to sort out the brain chemistry involved...
Does that mean that taking DHEA can somehow stave off the aging process? When scientists tested this proposition on animals, they found to their astonishment that it seemed to do just that. When older, slower mice were given DHEA, they became more active and learned as easily as younger rodents to run mazes. Other studies suggested that the hormone may help fight cancer, diabetes and heart disease...
...these effects were found in laboratory animals, not humans. Generalizing from mice to men is always risky, and it's even more so in this case because unlike humans, rats and mice make little or no DHEA on their own. Without conducting large studies of DHEA's effects on human subjects, nothing definitive can really be said...
