A Genetic Entrepreneur Sets His Sights on Aging and Death
On March 4th, Dr. J. Craig Venter announced that he was starting a new company, Human Longevity, which will focus on figuring out how people can live longer and healthier lives. The company will build the largest human DNA sequencing operation in the world, capable of processing 40,000 human genomes a year. This DNA data will be combined with other health data, in the hopes of gaining insight into the molecular causes of aging and age-related illnesses. Read this news story for more information.
Eat Plants And Prosper: For Longevity, Go Easy On The Meat, Study Says
New research suggests that Americans who eat a diet rich in red meat and cheese during middle age are significantly more likely to die when compared to people who consume smaller amounts of these foods. The study, published March 5th in the journal Cell Metabolism, was based on an analysis of data from NHANES, an ongoing study that surveys Americans about their eating habits and behaviors. The researchers tracked thousands of older adults to find connections between dietary patterns, disease, and death. The research shows that a low-protein diet in middle age is useful for preventing cancer and overall mortality. Read more here.
Drug Therapy Could Eventually Reverse Memory Decline in Seniors
Many people view memory loss as a normal part of aging- but researchers at the University of Florida say memory trouble doesn't have to be inevitable. Theirfindings, published in the Journal of Neuroscience on March 5th, suggest a drug therapy that could potentially reverse this type of memory decline. The drug can't yet be used in humans, but the researchers are pursuing formulas that could someday help aging adults who have trouble remembering daily items. Click here to read more.
Researchers Rejuvenate Stem Cell Population From Elderly Mice, Enabling Muscle Recovery
Researchers at the Stanford University School of Medicine have pinpointed why normal aging is accompanied by a diminished ability to regain strength and mobility after muscle injury. According to a study published in Nature Medicine on February 16th, over time, stem cells within muscle tissues dedicated to repairing damage struggle to generate new muscle fibers and replicate. Scientists identified for the first time a process by which the older muscle stem cells are rejuvenated to function like younger cells. Click here for more information.

Researchers had one group meditate, one exercise, and one as a control. Those who meditated missed 76% fewer days of work, those who exercised missed 48% fewer. -Sci Am. Mind Nov/Dec '12
