Amenacier writes: "Recent studies by Finnish and Swedish researchers have shown that drinking moderate amounts of coffee can reduce the risk of people getting Alzheimer's disease. The reason for this is as yet unknown, although it has been hypothesised that the high levels of antioxidants found in coffee may play a role in preventing dementia and Alzheimer's. Alternatively, some studies have shown that coffee can protect nerves, which may help prevent Alzheimer's. Other studies have shown that coffee may also help to protect against diabetes, another disease which has been shown to have links to Alzheimer's disease. However, researchers warn against drinking too much coffee, as 3 cups or more may cause hallucinations."
Amenacier writes: Melbourne scientists recently made the discovery that stem cells isolated from adult fat cells could be made to turn into beating heart muscle cells when cultured with rat heart cells. This discovery may lead to the usage of fat stem cells in the reparation of cardiac damage, or to fix such cardiac problems as holes in the heart.
It is proposed that culturing the stem cells with rat heart cells allows them to differentiate into heart muscle cells through the action of signals from the heart cells. In the future it may be possible to inject/transplant the stem cells into the damaged area and have them naturally differentiate into the type of cell required, with only the natural stimuli provided by surrounding cells required to effect the process, without any danger of rejection by the body.
