Wilderness Required
Number of pages: 4 | Number of words: 938.... to life. Colin Fletcher was one to claim that wilderness is needed:
“And when at last I walked on past the two juniper trees
toward the far side of the plateau I found I was feeling sorry
for any man who was not free to abandon whatever futility
detained him and to walk away into the desert morning with

within us, we may not always be sure that heat is given off. Our bodies
do not burst into flames but the perspiration on our skin is a clue to
what is happening.
The movement of the windsurfer has a different explanation.
The windsurfer is propelled along by a sail which collects mechanical
energy from the winds that sweep along the water. This energy has been
produced by the sun which warms the earth's surface and sets the air above
in motion. The sun's heat comes to the earth as a form of radiant energy.
When the heat reaches the sur .....

Gene Therapy 2
Number of pages: 14 | Number of words: 3631.... Possession of a normal gene leads to the continuous, regular production of ADA in cells throughout the body. Without at least one properly functioning gene, children have no way of converting deoxyadenosine (a waste product) into inosine. This leads to the rapid build-up of deoxyadenosine in the system, which becomes phosphorlyzed into a toxic triphosphate, which kills T-cells. The result is an almost complete failure of the immune system and early death.
Previous treatment options included bone marrow transplants, which worked well with matched donors. A major breakthro .....
