For the first time ever, biologists have regenerated an organ in a living animal. They did so by manipulating a single protein in elderly mice that makes their bodies rebuild their thymuses, an organ of the immune system. It's the first time an organ has been repaired with a chemical trigger and not via stem cell… » 4/10/14 9:30am 4/10/14 9:30am

Why Supercentenarians Hold the Key to Extended Life

Supercentenarians are rare people who have reached the age of 110 and remain fit. Amazingly, many of them never get sick, despite having some bad health habits in some cases. Scientists say it all comes down to genetics — which could lead to a gene therapy that promotes longevity. Here's how super-c's will help us… » 1/03/14 11:27am 1/03/14 11:27am

Scientists develop an 'elixir' that reverses a known cause of aging

To date, we know of only two things that can reverse the effects of aging: caloric restriction and extensive exercise. But in a recent experiment, researchers applied a new compound to 2-year old mice, causing their muscles to regenerate to 6-month old levels. Incredibly, human trials may start next year. » 12/20/13 8:40am 12/20/13 8:40am

What will jail terms be like when humans can live for centuries?

Radical life extension is coming. That means future societies will have to do a dramatic rethink of our ideas about how long offenders should be imprisoned and — more crucially — the ways they'll be rehabilitated. » 11/11/13 11:03am 11/11/13 11:03am

Scientists Discover Parts of Our Bodies Age at Different Rates

Some people age faster than others, but the discovery of a DNA body clock by UCLA researchers now shows that different parts of our bodies age faster than others. The discovery offers important insights into the aging process — and what we might be able to do about it. » 10/21/13 8:13am 10/21/13 8:13am

No, Extreme Human Longevity Won’t Destroy the Planet

It’s only a matter of time before humanity solves the aging problem. And resistance to radical life extension has already begun, driven by fears of overpopulation and the exhaustion of our planet's resources. Here’s why the critics are wrong. » 10/02/13 11:52am 10/02/13 11:52am

The first evidence that lifestyle changes can reverse aging

A new five-year pilot study has shown that lifestyle changes, like an improved diet, exercise, and stress management, may help reverse aging processes at the cellular level. But as exciting as this finding is, we’re still far from the proverbial fountain of youth. » 9/17/13 8:00am 9/17/13 8:00am

People who age prematurely could soon benefit from rejuvenation…

Humans age at different rates, as a result of various factors like lifestyle and genetics. Now, a new study from the ENGAGE Consortium suggests that people who age faster are at an increased risk of developing age-related diseases like heart disease, multiple sclerosis, and various cancers. The researchers suggest that … » 3/29/13 3:40pm 3/29/13 3:40pm

Transplanted Brain Cells Can Outlast The Body's Biological Clock

The problem with cells is that they have an expiry date. They can only replicate so many times before they hit a biologically predetermined limit and sputter out. But a recent study by neuroscientist Lorenzo Magrassi from the University of Pavia in Italy shows that mammalian neurons are not subject to this kind of… » 2/26/13 8:00am 2/26/13 8:00am

Could this immortal hydra polyp inspire advanced rejuvenation…

A tiny freshwater polyp called the hydra has a rather neat trick: It can't die. These polyps are able to accomplish this remarkable feat of apparent immorality by reproducing through budding rather than mating. But as geneticists from Kiel University in Germany recently discovered, the same longevity gene that makes… » 11/14/12 2:30pm 11/14/12 2:30pm

How to Live Forever By Turning Your Brain Into Plastic

We may never be able to freeze you at the moment of death and then reanimate you. But the good news is, there may be another way to keep your brain viable. A group of scientists have come up with a process called "chemical fixation and plastic embedding" — which essentially turns your brain into a hunk of exquisitely… » 9/14/12 11:13am 9/14/12 11:13am

Giving an old bee a youngster's job causes brain rejuvenation

Researchers at Arizona State University have successfully reversed brain aging in honeybees, by giving them responsibilities that are typically handled by much younger members of the hive. The change in occupation appeared to trigger a series of youth-restoring chemical processes in the bees' brain —processes that the … » 7/05/12 2:43pm 7/05/12 2:43pm
