Researchers discover a biological signature that can be used to predict the maximum lifespan of mammals

With the multitude of anti-aging products on the market today, it may be hard to believe that humans are one of the longest-living mammals. Why organisms age and how to slow down this process, or at least ensure that organisms stay healthy as they age, has been on the minds of many researchers over the years. Now, an international team of researchers called the Mammalian Methylation Consortium, led by Dr. […]

Longevity of dogs

Dogs are weird when it comes to predicting longevity based on body size. For many species, small body size means higher metabolic rate and shorter lifespan. For dogs, smaller body size = longer lifespan. Dr. Ana Jimenez (Colgate University) presented research at the Comparative Physiology meeting this weekend showing that larger dogs do indeed develop more DNA damage with aging than smaller dogs.
