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.
Geneticists try to understand and identify how these different outcomes result in shared or unique features. In humans about 100,000 genes are thought to be required for the development of a full grown adult from a single cell. This is an exciting year for geneticists because we are about to know the sequence of each gene that is present in a human cell. The sequencing of the human genome (see the Human Genome Project for more information) will help us to better understand how different physical traits are passed from parents to their children.
