By flushing out cells worn with age, researchers from the Mayo Clinic have extended the lifespans of mice by as much as 35 percent. It’s an encouraging finding that could eventually lead to similar therapies in humans.
Since the time of Darwin, evolutionary biologists have wondered why the lifespans of different species vary so significantly. A new model now suggests that the life expectancy of any given species is a function of evolutionary pressures — a conclusion that hints at the potential for powerful anti-aging interventions…
Researchers from the Scripps Research Institute and the Mayo Clinic have developed a new class of drugs that were shown to significantly slow the aging process in animal models. Remarkably, dramatic improvements were noticeable just days after treatment.
Scientists from Stanford Medical Center have devised a technique for extending the length of human telomeres. It's a breakthrough that could eventually result in therapies to treat a host of age-related diseases, including heart disease and diabetes. It could also result in longer, healthier lives.
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…
Nathan Rich of the New York Times has put together an article about the apparent "immortal" jellyfish, Turritopsis dohrnii, and how insights into its lifecycle could eventually lead to powerful rejuvenation therapies for humans. Not only is this article a must-read from the perspective of radical life extension, it's…
At first glance, the fact that we grow old and die seems like one massive evolutionary mistake. After all, if evolution is all about survival of the fittest, wouldn't the fittest individuals be those that can stay healthy and keep reproducing forever?
All animals eventually grow old and die. It's an inevitable fact of life - except when it isn't. Some animals, like tortoises and lobsters, never grow old, and learning their secrets could let humans live as long as they want.
One of the great mysteries of plant biology is a seemingly immortal tree called the Trembling Aspen (Populus tremuloides), which reproduces by growing clones from its root system. A new study suggests that the trees live for 20,000 years.
