Depressed Metabolism

In 2005 the American heart association revised its standards for CPR increasing the number of compressions from 80 cpm to 100 cpm, eliminating pauses for ventilation, and urging that focus be shifted to compressions (perfusion) rather than ventilation. This latter change is more profound than it might seem at [...]

If conventional cardiopulmonary support (CPS) in cryonics is difficult to perform adequately, and impossible to sustain for more than brief periods (30-60 min) before exhausting even a 3-man standby team, this is even more the case for active compression-decompression CPS (ACD-CPS) using the ResQPump (formerly the Ambu CardioPump). Even in the conventional medical setting of [...]

According to this news item the Alcor Life Extension Foundation is taking legal action against the brother and sister of an Alcor member who “denied the foundation’s request for his body and didn’t notify them of their brother’s death until months after he was buried.” Although some may question the wisdom of pursuing this case [...]

Hans Reichenbach’s The Rise of Scientific Philosophy is among the most accessible and illuminating statements of logical empiricism. Although the book can be read as an introduction to philosophy, the central message of the work is that most of what constitutes philosophy is either (outdated) pre-scientific speculation or incoherent reasoning.
One of the most powerful chapters [...]

Why the much anticipated medical breakthroughs of the early 21st century are failing to materialize
Saturday 30th May 2009, 2pm-4pm. Room 403 (fourth floor), Birkbeck College, Torrington Square, London WC1E 7HX. There’s no charge to attend, and everyone is welcome.

Mike Darwin has 30 years experience in cutting edge medical research. Co-founder of the Institute for [...]

In “Ice Baby” by Tom Mueller, the May 2009 issue of National Geographic announces the recent discovery of a 40,000 year old baby mammoth in Sibera. She is called Lyuba, named after the wife of the Nenet reindeer herder who found her, and is in near-pristine condition, having even her eyelashes. In fact, besides most [...]

At the hospital where Linda works, nurses and other employees swap many ‘helpful hints’ via email, and one of these ideas recently circulated seemed to be a technique cryonicists could use to increase the chances that their suspension organizations would find out quickly about their situations, in case of an emergency.
The way it works is [...]

In his article entitled ‘Evidence Based Cryonics’ Aschwin de Wolf unassailably argues that: “There is an urgent need to move from extrapolation based cryonics to evidence based cryonics. This will require a comprehensive research program aimed at creating realistic cryonics research models. It will also require vast improvements in the monitoring and evaluation of cryonics [...]

Basile J. Luyet (1897-1974) can be considered the father of modern cryobiology. His book “Life and Death at Low Temperatures” is a classic in the field and his journal “Biodynamica” evolved into a publication solely dedicated to the study of low temperature biology. Luyet identified the possibility of solidification without crystallization at low temperatures (vitrification) [...]

Less Wrong is a community blog devoted to refining the art of human rationality:
Over the last decades, new experiments have changed science’s picture of the way we think – the ways we succeed or fail to obtain the truth, or fulfill our goals.  The heuristics and biases program, in cognitive psychology, has exposed dozens of [...]

I realized recently that this year marks the 40th anniversary of the first manned landing on the moon.
The irony strikes me, for the Apollo missions did not lead to any follow-up in manned space travel. Nobody anticipated that we’d send men to the moon just a few times to establish dominance over the Soviet Union [...]

The philosopher Karl Popper has published on a wide variety of subjects but his most lasting contribution is his answer to the problem of induction by drawing attention to the asymmetry between verification and falsification. A theory can never be proven, but it can be falsified. Popper’s falsification criterion can also be used  to distinguish [...]

When I was in New Zealand in 1999, CI Member Cam Christie told me that one of his co-workers was against cryonics because she was a Jehovah’s  Witness and her church had a position against cryonics. I recently found an article about cryonics on the Jehovah’s Witnesses website:
The piece contains the statement:
“…the use of nanotechnology [...]

The cryonics organizations Alcor and the Cryonics Institute have taken great care to correct some of the persistent myths about cryonics. With so much widespread misinformation being circulated in the media it seems trivial to pay attention to some of the misconceptions that some people who are sympathetic to cryonics hold. But the price of [...]

Various approaches are available to investigate cryoprotectant toxicity, ranging from theoretical work in organic chemistry to  cryopreservation of complete animals. Because resuscitation of complex organisms after cryopreservation is not feasible at the moment, such investigations need to be confined to viability assays of individual cells and tissues or ultrastructural  studies.
One simple model that allows for [...]
