.... the possibility that scientists can develop medical treatments to enhance cell division and restore healthy heart muscle. It is too soon, however, to know to what extent such treatments might repair damaged hearts, such as those suffering congenital heart disease. Scientist and researchers at the University of Udine in Italy, studied hearts removed from 27 people who had received transplants. The researchers stained slices of heart tissue half a micrometer thick and used a confocal microscope to count the individual cell nuclei caught in the process of division. Jud .....

.... vital organs like the brain], serves as a complex lever system, acts as a storage area for calcium which is vital for human metabolism, houses the bone marrow within its mid cavity and to top it all it is capable of changing its architecture and mass in response to outside and inner stress. It is this dynamic remodeling of bone which is of primary interest in microgravity. To feel the impact of this dynamicity it should be noted that a bone remodeling unit [a coupled phenomena of bone reabsorption and bone formation] is initiated and another finished about every ten seco .....

.... (Young 25- 27) Take this for example; Say a woman is walking down the street carrying a child in her arms.

.... (Acquired ImmunoDifficiency Syndrome) weakens the body¹s immune system so it is sensitive to infection. The AIDS virus primarily attacks the T lymphocytes, which are a main part of the immune system. The virus is also incubated in cells called macrophages, where it is accidentally sent to other, healthy cells in the body like neurons and lymphatic cells. After HIV is contracted, the person looks and feels healthy for up to 20 years before symptoms start occurring. During this time, the person can give the virus to another even though it cannot be detected by sight or .....

.... a message of how much sunlight they see, and when it's dark. The sunlight prohibits the gland from producing melatonin, so at night, when there's no sun, the sleep-inducing hormone is released into our bodies. Because of the pineal gland and melatonin, humans have known to sleep at night and wake during the day since long before the age of alarm clocks. Humans don't produce melatotin right from birth; it is transfered in utero to babies through the placenta. For their first few days of life, babies still have to receive it from breast milk. Our levels of melatonin pea .....
