Can genetically modified mosquitoes wipe out malaria?

In theory, if you could create a stronger mosquito that's unable to spread malaria and release them into the wild, they would replace the mosquitoes that can spread the disease. But until recently, there has been a major glitch in this concept.

How Hereditary Illnesses Work

Hereditary illnesses are passed down from parents to their children like gene traits, and children might inherit a disease even though their parents never suffered from its symptoms. Learn about hereditary illnesses.

How Cryonics Works

Dozens of people are frozen in cryogenic storage facilities, waiting to be revived when science is able to cure whatever killed them. But if they're dead, is revival from a frozen state even possible? Find out.

How Gene Pools Work

The physical you is a result of your DNA, and your DNA is part of the human gene pool. Find out what the "gene pool" really is and what happens when it shrinks.

How does your body know the difference between dominant and recessive genes?

Ever since I took biology in high school I have wondered -- why do humans (and plants and animals) have two of every gene, and why is one "dominant" and the other "recessive"? How does my body know which one is dominant? How does it pick between the

How Designer Children Work

Given the choice, would you rather have been born with a different eye color, hair color or skin tone? Of course, you didn't have these options, but could you have them for your own children?
