Abstract

One thing that all living things have in common is that they grow through cell division. How is this growth regulated? Sometimes growth occurs when it is not supposed to, leading to cancer. Scientists are trying to discover how growth is regulated, hoping to find potential cures for cancer. One idea is that cells keep track of growth using special regions of the chromosome called "telomeres" that count how many divisions a cell has made. If this is true, then growth, cell division and age are all potentially related. Do organisms grow at the same rate throughout their lifetimes? Are there periods of rapid growth or regulated growth? Are there patterns in the rate of growth between different individuals? You can get your medical records to find out your growth history. Calculate the rate of growth by dividing the amount of growth by the time period during which the growth was measured. What periods of your life had the most rapid growth? When has there been little growth? Try to get similar data from different individuals in as many different age groups possible. Do you notice a relationship between the rate of growth and age?

Biologist

Life is all around you in beauty, abundance, and complexity. Biologists are the scientists who study life in all its forms and try to understand fundamental life processes, and how life relates to its environment. They answer basic questions, like how do fireflies create light? Why do grunion fish lay their eggs based on the moon and tides? What genes control deafness? Why don't cancer cells die? How do plants respond to ultraviolet light? Beyond basic research, biologists might also apply their research and create new biotechnology. There are endless discoveries waiting to be found in the field of biology! Read more

Physician

Physicians work to ease physical and mental suffering due to injury and disease. They diagnose medical conditions and then prescribe or administer appropriate treatments. Physicians also seek to prevent medical problems in their patients by advising preventative care. Ultimately, physicians try to help people live and feel better at every age. Read more
