One of the earliest observations in gerontology was the correlation of increased size with a longer lifespan. Presumably, being large makes one less prone to predators and allows better coping to starvation thereby decreasing your extrinsic mortality rate. At the same time, metabolic rate decreases when size increases and this could lower the extent of…… Continue reading Are cell membranes the pacemakers of metabolism?

The 8 frequently asked questions on telomerase and aging
Ever since the cellular clock called telomerase was discovered, it was hailed as the next big thing in anti-aging research. And the science world has been divided in two. One side evoked unlimited cell regeneration that might make degenerative diseases a memory of the past. The other side cautioned us that cancer cells unlock telomerase…… Continue reading The 8 frequently asked questions on telomerase and aging
3 simple things you must do to stop the aging clock
The dose makes the poison. In large doses, a stressor can kill you. In low doses, it can make you stronger. The specific adaptation that a cell derives from being exposed to a low dose of some stressor is called hormesis. And this concept is central to understanding aging. Because if cells – for whatever…… Continue reading 3 simple things you must do to stop the aging clock
10 animal species that made cancer a thing of the past
Although physicians have better technologies today to uproot cancer from the human body, receiving a diagnosis of cancer is still a very stressful ordeal, even when it is cured in the end or even when the tumor is not proved to be malignant in the first place! Lifestyle is important in preventing cancer, but at…… Continue reading 10 animal species that made cancer a thing of the past
