Planaria: A Model for Immortality

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Immortality.

“Is death necessary?“, asked biologist G. R. Taylor and stated that in 1968 in the USA alone more than a thousand teams of scientists were working on the issue of growing old and the problem of death. Some people are frozen at their death. They want to be revived as soon as a cure for their disease or the aging process has been found. Most of humanity seems to have the desire to live forever. M...

A New Immortality?

This paper was first published as ‘A New Immortality? Reflections on Genetics, Human Aging and the Possibility of Unlimited Lifespan’ in Evangelical Review of Theology: Journal of the World Evangelical Fellowship Vol. 23 No 4, (1999) 363-382. It was subsequently awarded a John M Templeton Award for Writing on Science-Religion and was republished in Robert L Herrmann (ed), Expanding Humanity’s V...

Aging and immortality in a cell proliferation model.

We investigate a model of cell division in which the length of telomeres within a cell regulates its proliferative potential. At each division, telomeres undergo a systematic length decrease as well as a superimposed fluctuation due to exchange of telomere DNA between the two daughter cells. A cell becomes senescent when one or more of its telomeres become shorter than a critical length. We map...
