... study now gives scientists the ability to identify those stem cells in the brains of living patients, and shows that these cells can be stimulated to turn into new neurons, principal author Dr. Steven A. Goldman told Reuters Health. In addition, it may lead to the development of drugs that would stimulate the formation of new brain cells in people with Alzheimer's or other diseases where brain cells degenerate, he commented. Goldman noted that the use of drugs to stimulate proliferation of new brain cells will probably re ...

Pollution And The Environment

... in the water is a very harmful tradition that people continue to do because it is putting a lot of sea life creatures in danger of being killed.

Oxygen

... to patients whose breathing is impaired and also to people in aircraft flying at high altitudes, where the poor oxygen concentration cannot support normal respiration. Oxygen-enriched air is used in open-hearth furnaces for steel manufacture. Most of the oxygen produced in the United States is used to make a mixture of carbon monoxide and hydrogen called synthesis gas, used for the synthesis of methanol and ammonia. High-purity oxygen is used also in the metal- fabrication industries; in liquid form it is of great importance as a p ...

Gold

... But other elements must be added to make gold hard. The purity of gold is measured in karats. Pure gold is 24-karats.

... Woolly Mammoth has, any known Ice Age temperatures would suffice since the thick fur protects the animal in any extreme temperatures. Large enclosures would not be needed as they would be for a normal elephant since the Woolly Mammoth is only three meters high. The huge tusks would allow it to scavenge for its own food, so no special feedings would be necessary. Feedings would also be needed on a less frequent basis since the Woolly Mammoth, much like today's camels, keeps under its sloping back a thick layer of blubber as nutrition when ...
