Sea squirts might not look like much...they're simple, hermaphroditic creatures that barely even have a brain. But they have a particular knack for activating the enzyme telomerase, which protects DNA from degradation. That unexpected talent could help fight human aging. More »

It's been known for a while that restricting your diet will increase your lifespan, but now researchers have shown one reason why: Eating less causes your ribosomes (your cells' protein factories) to mutate. And it's looking like mutated ribosomes (pictured here) could be one key to life extension. The good news is that you may not have to starve yourself to mutate your ribosomes anymore. Biologists at the University of Washington have managed to induce the life-extending mutation in ribosomes with a drug that doubles the lifespan of yeast cells. More »

There is now a way to extend the lifespan of organisms so that humans could conceivably live to be 800 years old. In an amazing development, scientists at the University of Southern California have announced that they've extended the lifespan of yeast bacteria tenfold — and the recipe they used to do it might easily translate into humans. It involves tinkering with two genes, and cutting down your calorie intake. Tests have already started on people in Ecuador. More »
