About "Ask A Scientist!"
On September 17th, 1998 the Ithaca Journal ran its first "Ask A Scientist!" article in which Professor Neil Ashcroft , who was then the director of CCMR, answered the question "What is Jupiter made of?" Since then, we have received over 1,000 questions from students and adults from all over the world. Select questions are answered weekly and published in the Ithaca Journal and on our web site. "Ask A Scientist!" reaches more than 21,000 Central New York residents through the Ithaca Journal and countless others around the world throught the "Ask a Scientist!" web site.
Across disciplines and across the state, from Nobel Prize winning scientist David Lee to notable science education advocate Bill Nye, researchers and scientists have been called on to respond to these questions. For more than seven years, kids - and a few adults - have been submitting their queries to find out the answer to life's everyday questions.
There are also many kinds of diseases that are not caused by infections. Many of these can be treated with medicines so that people who have them feel better or live longer, but this does not mean that they are cured. For example, diabetes (high blood sugar) can be improved by diet and exercise, and also by medicines such as insulin. However, diabetes is not cured completely by any of these treatments. Patients who have diabetes need to stick to their diets and keep taking their medicines, or the symptoms of diabetes come back.
Some infections that used to be incurable now can be cured with medicines. Hepatitis B, a liver infection, can be cured in some cases using a combination of medicines that fight the virus and stimulate the body's immune system. Unfortunately, we don't know today whether a similar cure for HIV/AIDS will ever be discovered, or how long it might take.
