The fruit fly, from egg through larva and pupa to adult, lives for a mere 14 days, while the world’s oldest known terrestrial animal, This startling variation in lifespans raises a fundamental question, however: why do some animals and plants live to a ripe old age while other, apparently very similar, lifeforms spend dramatically short times on Earth?

It included a multidisciplinary research team from the former Institute for Ageing and Health at Newcastle University and a participant cohort of more than 1,000 85-year olds from Newcastle and North Tyneside.

Thomas Burton Loram Kirkwood CBE FMedSci (6 July 1951, Durban, South Africa) is an English biologist who made his contribution to the biology of ageing by proposing the disposable soma theory of aging. Episode 3 of 5 4 0 obj
A chance encounter with Robin Holliday at the NIMR sparked a collaboration on the cell and molecular mechanisms of ageing. “One has wings and the other does not. The big questions now are: How do we address the awesome complexity of a process that is driven by so many elements working and interacting together? endstream
The study began in 2006 and was led by Professor Tom Kirkwood. He is the author of Time of Our Lives: The Science of Human Aging (1999), The End of Age: Why Everything About Aging Is Changing (2… Join Facebook to connect with Tom Kirkwood and others you may know.

And, at a deeper level of biological curiosity, what are the mechanisms that sustain the ‘immortality’ of the germ line – the essential lineage of reproductive cells that carries life onward from generation to generation?The fact we are living longer is in many ways humanity's greatest success but there is a sting in the tail.
