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.

Scientists have come up with a new technique to modify the genes of plants, insects and animals. This “gene drive” technique may be able to stop the spread of diseases that insects carry, such as Malaria and Zika, but also has some dangers. For example, releasing genetically modified species could lead to an unbalanced ecosystem, destroy other species, or spread other diseases. Listen to the story to hear more about why this technique is controversial.

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.

Potatoes are a staple in many households. So it’s natural researchers have worked to create a better potato with genetic modification. Geneticists have been able to change and improve potatoes to make them safer and cut down on waste, but potato buyers are refusing to buy them. Listen to learn more about how the potato has been improved, but why many food manufacturers don’t want to use them.

Illness can be caused by viruses and bacteria, but some very serious illnesses come from your actual genes, your DNA. Scientist have been able to identify genes that cause illness but until now they haven’t been able to fix them. A new discovery creates the framework for editing these problematic genes. This public radio story tells the unlikely story of this discovery and discusses its potential.
