Researchers at Stanford University just published a study in Nature that may give new hope to those looking to stop the effects of aging on the brain. The study found that when blood from a young mouse was injected into an older mouse, that older mouse enjoyed what could almost be termed a "rejuvenation effect": it began producing more neurons, firing more activity across synapses, and even suffered less inflammation.
Bill Andrews has spent two decades unlocking the molecular mechanisms of aging. His mission: to extend the human life span to 150 years--or die trying

Bill Andrews's feet are so large, he tells me, that back when he was 20 he was able to break the Southern California barefoot-waterskiing distance record the first time he put skin to water. Then he got ambitious and went for the world speed record. When the towrope broke at 80 mph, he says, "they pulled me out of the water on a stretcher."
Remember last year’s death-predicting longevity-gene study, estimating who is likely to live to 100 and who will not be so lucky? Well, the authors of the study have retracted their paper. But there’s a catch: They claim they were still right.
Harvard scientists may be a step closer to a medical fountain of youth after figuring out how to reverse the aging process in mice. The breakthrough could lead to a way to slow the aging process in humans which in turn could extend quality of life by reducing the impact of age-related ailments like heart disease or dementia. That is, if it doesn’t kill them first.
Scottish researchers may have found a key to preventing senior moments, by blocking a stress hormone that interferes with memory. The treatment works surprisingly fast in mice, improving their memory within a few days, and the researchers say it might be a good treatment for elderly people who want to stay sharp. They want to start human trials soon.
Humanity's search for the secrets to immortality has inspired Ray Kurzweil's Singularity vision and DARPA's hunt for ageless synthetic beings. Now scientists have discovered a single gene that appears to control how quickly individuals will biologically age, The Telegraph reports. The discovery could not only encourage people to adopt healthier lifestyles earlier, but may eventually help people live longer if scientists can figure out how to manipulate the gene.
A new genetic database for 100,000 elderly Californians is slated to come online within two years, and marks the first time that genetic data becomes available for such a large and diverse group.
Health-care provider Kaiser Permanente will hand over patient data that includes electronic health records, lifestyle surveys, and info on air and water quality in patients' neighborhoods. The effort draws on $25 million from the National Institutes of Health, and also involves researchers from the University of California, San Francisco.
Military leaders throughout history have supposedly goaded on their troops with the phrase, "You wanna live forever?" In 2009, the answer for many people is "Yes, please," and the Nobel Committee has today honored three U.S. scientists for discovering the genetic code that regulates aging in cells.
Along with flying cars and underwater bubble cities, pills curing every ill are a staple of science fiction. But while aero-autobahns and submerged metropolises have not moved any closer to reality, medical science has advanced to the point where pills once considering miraculous may soon be a reality. Popular Science has a rundown of the top future pills that may one day change your life. Launch it here.
Scientists find the stuff that makes bread oh-so-tasty also may cure everything from Lou Gehrig's disease to aging

You know that humans have used yeast for thousands of years for baking and brewing, but did you know that it’s also prized for its applications in medical research?
The metabolic processes of yeast cells are similar to mammal cells, and since yeast reproduces quickly, experimental results can be obtained much faster than they would using animals. Yeast’s rapid reaction time has allowed scientists to put all sorts of research in fast-forward, with the aim of efficiently developing new disease treatments.
