Evolution: Escaping the Inevitability of Ageing

William Hamilton argued that even species inhabiting the farthest flung corners of the universe should age. However, a recent study shows that to find a species that escapes ageing, you only need to look as far as your local pond.

The Inevitability of Xen

Xen is a virtual machine monitor (VMM) that we have developed at the University of Cambridge over the past 5 years. As a VMM, Xen allows a single physical computer to be partitioned into a set of isolated virtual computers, each running their own operating system and applications. Xen has received a fair bit of attention recently and we have even spun out a company to support the commercial use...

Evolution and ageing.

Did senescence evolve as a direct result of natural selection in order to limit the life-span or did increases in longevity evolve in the face of random events that ordinarily limit the life-span? The adaptive hypothesis is that senescence is a programmed process which appeared in evolution because a limited life-span has selective advantages for certain species. Non-adaptive theorists hold tha...
