Stem cells for flu? For me, that idea is new. Some months back there was buzz about the stem cell biotech Longeveron related to its report on early trial data on testing infusions of mesenchymal stem cells for frailty in the aged. Frailty that pops up in some aging folks can manifest in a variety …

Young blood as anti-aging fountain of youth: hype or hope?

There’s an idea floating around out there called “young blood” to use donations from young folks to infuse older people to reverse aging. I’m skeptical. Imagine an old man and a teenager sitting side by side, with blood flowing from the kid to the oldster in a stab at anti-aging. Sort of like a one-way …

Is there a stem cell connection between the brain and aging? Could a type of brain stem cell or the exosomes it secretes control whole body aging? A recent big Nature article from the lab of Dongcheng Cai argues an emphatic “Yes” to these questions, at least in mice. In the Zhang, et al paper, entitled …

Has anti-aging finally come of age with Google’s Calico?

Can Google’s new anti-aging company, Calico, have you Googling at age 140? Don’t sell your burial plot just yet. The idea of anti-aging has been around for a very long time and efforts to combat aging have spanned millennia largely without any success so Calico (apparently short for California Life Company, which sounds more like …

Caloric restriction: dieting monkeys teach human scientists?

30monkey-popup

The notion of caloric restriction (CR) as a means to prolong human life is intriguing. The basic idea of CR is that if you eat a lot less than the average person you’ll live longer. You might even live a higher quality, healthier life. But is this true? (update: see my newer post on 5 …

Regenerative medicine is very exciting. But what’s even better than regenerative medicine? Preventative medicine. If one can prevent a problem for occurring in the first place, it is far better than trying to treat it after the fact. Of course in many cases we do not know the causes of diseases so it is difficult …
