More money is spent on treating cancer than preventing it within the United States. However, scientists are getting closer to finding out if cell growth within our bodies promotes already existing cancer. Scientists are examining microscopic cells to test if certain spices and foods affect the reduction of cell growth. Listen to learn about the budget behind cancer research and how human behavior can increase the chance of cancer.

America's dairy farms today have fewer cows, but those cows are producing more milk than ever before. The dairy cows are being bred to be larger, hungrier, and more productive. The focus on genetics to produce more milk has raised concern among livestock advocates. There are criticisms that the trade-offs are not worth it. Some think that finding ways to keep the cows content will increase milk production. Listen to learn more about the debate about genetics and dairy cows.

Cells are used in research to make scientific discoveries. A certain set of cells are among the most widely used in biomedical research worldwide. These HeLa cells have been used to research almost every disease and have played an important role in many scientific breakthroughs including the development of the polio vaccine. The cells come from a woman named Henrietta Lacks who has been mentioned in more than 70,000 published scientific papers. Listen to hear more about how these cells are used and the issues of privacy with her family.

Human embryonic stem cells are able to become any kind of tissue in the body. Because of this, many researchers see huge potential for curing and preventing disease. Up until now this has been theory, but a new study has had early success in using stem cells to improve the eyesight of the blind. This sound-rich story takes you into the operating room to hear the eye surgery and meet someone whose life was changed by the procedure.

Scientists are experimenting with genetically modifying mosquitoes to wipe out some diseases like malaria. Every year malaria kills a million people. This new technique uses genetic engineering to alter mosquitoes genes. It’s a practice called “gene drive” and it’s controversial because it can be use to eradicate disease but could also be used as a weapon. This audio story explores the science behind gene drives and the controversy surrounding the technique.

We live in an age when genetic engineering has the capacity to affect the course of human evolution. Scientists can edit human DNA, which could have profound benefits for society, but this ability also comes with dangers. Editing human DNA can allow for the treatment and prevention of disease, but this modified DNA can also become a permanent part of human genes, passed down from generation to generation. The scientific community met to discuss these issues. While experts agreed that creating a baby with edited DNA is unsafe, the support continued research to see what is possible. Listen to hear more about this issue and what scientists have concluded.

Scientists say that in the future they will be able to make modifications to human DNA that can be passed down to subsequent generations. These same scientists say that such genetic modifications should only occur in cases of serious disease or disability and must be tightly regulated. However, there is fear around the idea of scientists altering the course of evolution and creating “genetically superior” humans. Listen to learn more about developments in genetic modification and debate: Should we make changes to human DNA?

New technology can help athletes gain a deeper understanding of how their bodies work. By submitting their DNA, athletes can see the results of their genetic fitness assessment. This can help athletes personalize their training routine, gain information about their ability to build muscle, or find out how prone they are to joint injuries. The results are organized in categories to let people know what they need to work on. Listen to learn more about this new technology and then debate: Should DNA determine the sport you play?

A team of scientists has genetically engineered pigs to be resistant to a widespread disease. Science can engineer an animal’s DNA to introduce desirable traits and get rid of negative traits or sickness. These pigs are not being raised on farms yet, but the plan is to have food from these animals available in stores in the next five years.This technology is still new, and the Food and Drug Administration has strict guidelines that have to be met before these animals will be available to the public. Listen to hear more about genetically engineered animals and then debate with your class whether you think genetically engineered animals will be safe to eat.
