Antibodies are one of the major players in the immune system’s attack against germs. Learn what they are, what they do and how they keep us healthy.
A technique inspired by how cotton candy is spun could help produce lab-grown meat at a lower cost and on a bigger scale.
How do we learn what a particular molecule does in the body? To find out, scientists often 'knock out' the gene that makes it. Here’s how.
Scientists are using a tool called CRISPR to edit DNA in all types of cells.
Scientists combined an egg, sperm and some donor DNA: The end result: what appears to be healthy babies.
Scientists have recently been reporting big advances in the ability to tweak the genes of living organisms, including people. But some question the ethics of doing that. A panel of experts now says such research can go ahead — with one major exception.
Former President Jimmy Carter has a potentially lethal type of skin cancer that has already spread to his liver and brain. Recent improvements in medicine may help him fight it.
Hijacking a cell process called RNA interference can let scientists turn off a selected gene. Its silencing can point to what genes do when they’re on — and may lead to new treatments for disease.
When a baby frog develops from an egg that’s never been fertilized, we call that parthenogenesis.
