Editing Human Genes

Life Science DNA Biotechnology Cells

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 they also come with dangers. Editing human DNA can allow for the treatment and prevention of disease, but edited DNA can also be passed down from generation to generation, becoming a permanent part of human genes. The scientific community met to discuss these issues and clearly stated that creating a baby with edited DNA is dangerous and unsafe, but supported the basic research to see what is possible before taking any next steps. Listen to hear more about this issue and what scientists have concluded.

Henrietta Lacks and Patient Privacy

Life Science Cells

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.

The Smallest Genome

Life Science Cells

A group of synthetic biologists report they've created an organism with a minimum number of genes required for survival and reproduction. Humans have about 20,000 genes, and this new single-celled organism has only 473 genes. That makes it the smallest genome of any known living thing that can reproduce. The goal is to be able to design cells that could produce new industrial products such as chemicals and fuels from raw materials. Listen to hear more about the potential of this new creation.

Microbes are Still a Mystery to Scientists and the Diversity of Life

Life Science Genetics DNA Human body Cells

The study of genes is moving toward a new frontier. There is a new field studying the little known field of microorganisms. Microbes run every process on earth. And a human is made up of 90% bacteria, or microorganisms. And yet we know very little about microbes. This public radio story looks closely at the microscopic microbes.

Preventing Cancer at a Cellular Level

Life Science Health Genetics Human body Cells

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.
