They attack cells that display foreign antigens on their cell surface, often including the cells of a transplanted transplanted organ or a donated skin graft. T cells are believed to be the lymphocytes (white blood cells), ordinarily responsible for preventing the development of cancer. Cancer Cancer cells are abnormal cells that most likely display altered altered antigens. As long as T cells are capable of recognizing newly developed cancer cells, a cancerous growth cannot begin. Therefore when cancer is present, it most likely signifies signifies a failure of the immune system, which stress can sometimes be responsible. Interferon is a chemical that is produced by T cells as well as most other cells. In the past it was noted that interferon entered noninfected cells and in some way still to be determined, determined, prevented viral invasion of those cells. Recently it has been found that interferon also stimulated the immune system, and preliminary preliminary studies have suggested suggested that it might by helpful in treating cancer patients. ASTRONOMY The Earth dates back to 4.6 billion years. It took three billion years to pass before intelligent life appeared. A prime requisite for habitable planets is from 1 -100 Billion years. In May 1960, Frank Drake, a renowned astronomer astronomer used an 85-foot radio- telescope of the National Radio Astronomy Observatory Observatory at Green Bank, West Virginia to send radio messages into space in search of other intelligent extra tres- trials! Now many radio observatories observatories are constantly searching searching the cosmos for forms of life. In our Milkyway Galaxy there are billion of stars, and it is estimated that 100 thousand thousand of those stars have suitable suitable planets for intelligent life forms. There are billions of other galaxies besides our own, each having the possibility possibility of having 100's of thousands of intelligent "beings." To send a radio message to the closest star to our sun which is Proxima Centauri, 4.2 light years away, it 'would take 4.2 years (light and radio waves travel at the same speed - 186,283 miles per second). To travel this distance at the fastest rate now available to man would take 24,000 years for a one way trip - pack a lunch Mom.

COMMON COLD The common cold is a general inflammation of the mucous membranes of the respiratory passages caused by a variety of viruses. Colds are highly contagious. On the average, Americans contact two or three colds per year. Factors that lower the body's resistance to virus infection are fatigue, overexposure to cold, recent or present infections, infections, allergic reactions, and inhalation of irritation dust or gas. The virus is spread about two days before the symptoms appear. Prevention of colds includes adequate sleep and a well-balanced diet. Treatment includes adequate fluid and protein intake to sustain the losses that occur with fever. Vitamin B6 helps in the production of antibodies that defend the body against infection. infection. Vitamin A is necessary to maintain the health of the mucous membrane of the respiratory passages. Some individuals have found that vitamin D is also helpful in the prevention of colds.
