Depressed Metabolism

Brownian motion started when Robert Brown looked into his microscope and observed that pollen suspended in water moved around in a continuous random motion. Wanting to rule out some “vital life force,” Brown also  investigated dead things such as sand and metals but he observed the same jittery motion. The dead danced as well. Or [...]

“On November 15-16, 2008, the world’s most dangerous ideas will collide in Mountain View, California. Convergence08 examines the world-changing possibilities of nanotech and the life-changing promises of biotech. It is the premier forum for debate and exploration of cogtech ethics, and ground zero of the past and future infotech revolution. Convergence08 is an innovative, lively [...]

Ever since humans imagined the ability to deliberately manipulate matter on the atomic scale, they have glimpsed the boundless possibilities of the science of nanotechnology. And for almost as long, they have disputed whether molecular machines should be built using a “hard” (physical engineering) or “soft” (biology-based) approach. On his blog, Richard Jones, author of [...]

Immortality as a zero probability of information-theoretic death may not be possible or realistic. A more practical (and less controversial) objective of radical life extension would be to minimize the chance of information-theoretic death. In analogy with Aubrey de Grey’s objective to cure human aging by engineering negligible senescence (SENS), the objective of radical life [...]

One concern about chemical fixation as a low cost alternative to cryonics is that current fixatives may not be able to permanently fix all biomolecules that are important to preserve the identity of the person. A related concern is that postmortem delays may not permit adequate perfusion of the brain, resulting in pockets of [...]

Twenty years ago, Charles B. Olson published an article called “A Possible Cure for Death” in the journal Medical Hypotheses. In it, he favorably compares methods of chemical preservation to cryogenic preservation. Unfortunately, this article provoked no wide discussion or attempts at implementation. As the author notes on his website, other than requests for [...]
