long telomeres

Are long telomeres better than short ones? What about older folks lengthening their telomeres somewhat or stabilizing the length? Could this counter aging? As with many things, the story is far more complicated than we might hope. For background, telomeres are special structures protecting the ends of chromosomes. I remember as a young student that […]

Oliver Zolman, Bryan Johnson

Near-billionaire Bryan Johnson apparently does not like getting old and he’s trying to do something transformative about it. He and his team are experimenting in a big way.  As a 55-year-old myself, I can’t blame him for wanting to fight aging in general. However, his anti-aging project includes some extreme stuff.

Senolytics Steve Horvath

When we hear the word senile we might think stereotypically of an older person who has cognitive impairment, but some argue that senility can apply to cells too as they age and that such cells can be targeted by drugs called senolytics. Unfortunately, the supplements industry has picked up on this idea to sell iffy

Boning up on stem cells for osteoporosis: good idea, little data so far

osteoporosis, stem cells for osteoporosis

It’s great when an idea like stem cells for osteoporosis just makes so much common sense, but it still requires data. A logical hypothesis is not enough. The point of today’s post is to fact-check the idea of using stem cells for such bone loss. A femur to stand on? Unfortunately, the take-home message is
