Can young blood stem the ravages of old age? – Jess Zimmerman. Saul Villeda, who leads a stem-cell research lab at the University of California, San Francisco, is not concerned about a black market for baby blood.
‘You sound like my mother,’ he told an anxious reporter for the New York public radio station WNYC’s science programme Radiolab in an interview last year. ‘She’s worried that all of a sudden 16-year-olds are going to go missing.’ Villeda’s mother has reason to worry, sort of. Her son’s research has found that blood from young mice can improve the learning and memory of old ones, and she’s certainly not the only one to wonder what this could mean for humans. In his lab at UCSF and his postdoc lab at Stanford, Villeda and colleagues injected old mice with blood plasma from young mice, and vice versa.

Dr. Clyde Yancy, a professor of medicine and chief of cardiology at the Northerwestern University’s Feinberg School of Medicine, said a sharpended focus on health prevention — including seven steps to a healthy lifespan — could add a decade or more to the average person’s life. "Achieving these seven simple lifestyle factors gives people a 90 per cent chance of living to the age of 90 or 100, free of not only heart disease and stroke but from a number of other chronic illnesses including cancer," Yancy said. Yancy will deliver the Heart and Stroke Foundation of Canada Lecture at the opening ceremonies of the Canadian Cardiovascular Congress in Vancouver Sunday. Does Life End at 35? Do you sometimes lie awake worrying that you aren't succeeding fast enough? Are you tortured by younger peers who have global businesses, penned acclaimed books and a string of iron-man medals? Do you count down the years until you can no longer make the 30 under 30 list?
Take a deep breath. Google’s New Company Calico To Try to Cheat Death. A joke about Silicon Valley is that entrepreneurs always seem to focus on the problems facing people of their own age.
That’s why young programmers have endless ideas for websites that will tell them what bar to hang out in. Then, in middle age and with marriage, it’s onto inventing fertility apps (see “Three Questions for Max Levchin About His New Startup”). Eventually, as your hair goes gray, you have to fix death itself. Today, Time magazine broke the news that Google and its CEO Larry Page are funding a company that will try to extend human lifespan and solve the diseases of aging.
The weekly’s next newsstand cover asks, in huge letters, “Can Google Solve Death?” Pretty obviously, Google isn’t going to solve death. The Time article—and a Google blog post released at the same time—provided scant detail about what the new company, called Calico, will actually do. “OK … so you’re probably thinking wow! Ca.news.yahoo.com-removing-old-cells-could-extend-human-life-213606774.html.url. The old adage "Out with the old and in with the new" could help prevent age-related diseases if applied to certain cells, new research on mice suggests.
By removing the body's worn-out cells, called senescent cells, several times during the lifetime of aging-accelerated mice, researchers were able to spare the mice of cataracts, aging skin and muscle loss. "We started treating animals when they were really young, before they started to establish these senescent cells," study researcher Darren Baker, of the Mayo Clinic College of Medicine in Minnesota, told LiveScience. "As a cell became senescent we would remove it; we saw a really profound effect. " Senescent cells These cells were once important contributors to their cellular community.
For some reason, the ones that stick around start pumping out odd proteins. The number of senescent cells increases as tissues age; at most they will make up 15 percent of cells in mammalian tissues, the researchers said. Out with the old Healthy aging.

Bill Andrews is deadly serious. He wants to live forever, and he's definitely not crazy. The more you know about him and his quest the more you realize he's actually on to something really big. Chinese "mushroom of immortality" genome mapped. By Dan Vergano, USA TODAY Updated 2012-06-26 6:04 PM A medical mushroom has joined the modern age, added to the ranks of gene-mapped organisms.
Genome sequence of Ganoderma lucidum illustration Used in Chinese medicine for centuries, the Lingzhi "mushroom of immortality" or Ganoderma lucidum, has "antitumour, antihypertensive, antiviral and immunomodulatory," properties, notes the Nature Communications study led by Shilin Chen of the Chinese Academy of Medical Sciences & Peking Union Medical College. Some 400 medically-active compounds are made by the mushroom, the study authors note.
