A new treatment that blocks an aging-related protein restored lost cartilage in old mice and helped prevent arthritis after knee injuries. Human cartilage samples showed similar signs of regeneration, raising hopes for a future drug that could repair joints instead of replacing them.
it’s always seemed weird to me that aging takes 20 years in dogs but 80 years in humans. i mean, if it’s a physical hardware failure, then you would expect it to be independent of age and only dependent on past physical load.
Not a scientist, but from what I know it’s all linked and proportional to a species’ lifespan, so dogs are growing up faster, but also aging faster than humans in general. If a human reaches sexual maturity at 15, a dog does so at 1 or 2.
