While DNA is the building block of life, its cousin RNA keeps the show running smoothly, as it carries the information from DNA that allow genes to be expressed. RNA's ability to increase or decrease the expression of genes means it has huge potential to treat diseases at the genetic level, including tumors and…

Pandas aren't exactly renowned for their health and hardiness — if anything, they've earned a reputation as a fragile, sex-averse species that needs constant human conservation just to keep from going extinct. Well, they might be about to repay the favor in a big way, thanks to a powerful antibiotic locked inside their …

The drug rapamycin comes from bacteria found in the soils of Easter Island. It's helped save lives for over a decade by preventing rejection in organ transplants, but that might just be scratching the surface of what it can do.

Some laboratory mice were given specially engineered insuling-producing genes. These genes were then remotely activated using radio waves. This could mean a whole new field of medical procedures in which we turn genes on and off at will.

Chocolate, like any other candy, makes you fat. That's such a basic and well-known fact that it's easily taken for granted... but it could be wrong. New research reveals that people who regularly eat chocolate are thinner than those who don't.

The gene PTEN is a tumor suppressor, making it one of the best genes to have in the fight against cancer. But the latest research suggests that preventing cancer is just the beginning of all the amazing things this gene can do.

An exciting new finding suggests that a specific enzyme in the brain is responsible for blocking the creation of new memories in Alzheimer's patients. And stopping that enzyme has already reversed Alzheimer's symptoms in mice. This could be a major breakthrough.

Because flu viruses mutate so fast, the only way to stop them is to destroy their ability to evolve. That's the key to creating a universal flu vaccine... and now we may have found the secret to creating one, and wiping out the flu.

Some of the most deadly human diseases work by worming their way inside your DNA, attaching themselves to the cell's chromosomes. This makes them almost impossible to remove. But a new molecule designed to bamboozle rogue DNA could change everything.

Scientists have long searched unsuccessfully for the genetic factors that cause schizophrenia. Now we know why: the disorder is actually caused by what happens in cells around the genes. That knowledge could give us our best treatment yet for schizophrenia.
