Survival curve shows increase in average lifespan, and now Sima has become the longest-lived Sprague Dawley rat
Heart muscle aging reversed (in mice)
An interesting article in New Scientist this week regarding using the blood of younger mice to reverse the signs of aging in older mice - full article here - using daily injections of the protein GDF11. Not only could this help prevent early deaths in humans (by repairing damaged heart muscle after a cardiac arrest) but is an apparent demonstration that rejuvenation will one day be possible - its hard to argue that you couldn't choose to live forever if your body could be continually rejuvenated. Let's stay healthy out there to make sure we get over the finishing line!
