Venki Ramakrishnan: Aging is an accumulation of chemical damage to the molecules inside our cells, which damages the cells themselves, and therefore the tissue, and then eventually us as an ...
Venki Ramakrishnan, a Nobel laureate and former president of the world's oldest scientific academy, the Royal Society, has been watching as aging science and the hype around it has exploded.
Venkatraman Ramakrishnan (born 1952) is a British-American structural biologist. He shared the 2009 Nobel Prize in Chemistry with Thomas A. Steitz and Ada Yonath for research on the structure and function of ribosomes .
Venkatraman (Venki) Ramakrishnan (Indian-born American and British, 1952– ) — winner of 2009 Nobel Prize in Chemistry (with Steitz and Yonath) for crystal structure of the 30S subunit of the bacterial ribosome; Ayyalusamy Ramamoorthy — solid-state NMR; John Randall — X-ray and neutron diffraction of proteins and DNA
Biogerontology should not be confused with geriatrics, which is a field of medicine that studies the treatment of existing disease in aging people, rather than the treatment of aging itself. There are numerous theories of aging, and no one theory has been entirely accepted.
The somatic mutation theory of ageing states that accumulation of mutations in somatic cells is the primary cause of aging. A comparison of somatic mutation rate across several mammal species found that the total number of accumulated mutations at the end of lifespan was roughly equal across a broad range of lifespans.

A Stanford Medicine study found that human aging speeds up at 44 and 60. Here, doctors share how to quell it by cutting alcohol, strength training, and more. Your Body Ages Rapidly In Your 40s And ...
In 1968 it took the form and became known as the neuroendocrine theory of aging. [38] [39] [40] 1956 Denham Harman proposed the free-radical theory of aging and demonstrated that free radical reactions contribute to the degradation of biological systems. [41] The theory is based on the ideas of Rebeca Gerschman and her colleagues put forward in ...
