The RhinoChill: A New Way to Cool the Brain Quickly

We scientists are difficult, cranky, and above all, maddeningly frustrating people. Want to turn lead into gold? No problem, we can tell you how to do that, and in fact have even done it already: the only catch is that … Continue reading

At last, a sure-cold way to sell cryonics with guaranteed success!

A humorous romp through a promising new technique in aesthetic medicine from one cryonicist’s (warped) point of view. Figure 1: Before cryopreservation (L) and after cryopreservation (R). As everyone involved in cryonics for more than a fortnight is sadly aware, … Continue reading

Response to Aschwin de Wolf’s ‘Evidence Based Cryonics’

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 … Continue reading

A simple method to resuscitate rats from cold circulatory arrest

This is the eighth entry in a series about resuscitation of non-hibernating rodents from circulatory arrest at ultraprofound hypothermic and high subzero temperatures. In 1982, P.D. Rogers and G.P. Webb published some of their observations (based on previous papers and … Continue reading

Cryonics sets example for emergency medicine

One of the most neglected aspects of cryonics is that its procedures, and the research to support them, can have important practical applications in mainstream fields such as organ preservation and emergency medicine. Contrary to popular opinion, cryonics does not … Continue reading

Early total body washout experiments in cryonics

The question of whether cryonics “works” or not is too general and hides the  point that progressive breakthroughs can make the concept more plausible. Human cryopreservation consists of a number of procedures culminating in long term care at cryogenic temperatures. … Continue reading

D(+)-Lactose and other sugars in organ preservation and cryonics

A PDF file of this document is available with images and structural visualization of various sugars. D(+) lactose monohydrate is the principal sugar in mammalian milks. The monohydrate part is easiest to explain; it simply means that the lactose molecule … Continue reading

Dogs resuscitated after 3 hours of cardiac arrest from exsanguination

Despite sensational news items about “zombie dogs,” biomedical researchers and clinicians have known for a long time that interruptions in consciousness and blood circulation can be reversed without neurological deficits, provided such events do not produce ischemic injury. There are … Continue reading

Induction of hypothermia before CPR improves survival

It is difficult to match concerns about reperfusion injury during cardiopulmonary resuscitation (CPR) with specific proposals for alternative interventions. After all, no matter how harmful the effects of oxygenation may be, not restoring circulation in a patient in cardiac arrest … Continue reading

Critical cooling rate to prevent ischemic brain injury

Induction of hypothermia can reduce injury to the brain when it is deprived of oxygen. How fast do we need to cool a patient during cardiac arrest or stroke to prevent irreversible injury to the brain? It is an established … Continue reading

H.P. Lovecraft’s “Cool Air” and cryonics

In “Heritage of Horror,” Lovecraft scholar S.T. Joshi writes that Lovecraft’s short story “Cool Air” “anticipates cryogenic research.” We can forgive Joshi the common mistake of writing “cryogenics” when he means “cryonics,” but how much cryonics is there really in … Continue reading

Liquid ventilation in cryonics

After legal pronouncement of death, cryonics patients benefit from rapid stabilization to protect the brain from injury. The most fundamental intervention is induction of hypothermia. Unlike other interventions such as cardiopulmonary support (CPS) and administration of neuroprotective medications, induction of … Continue reading

Hypothermia, shivering and cryonics

The objective of cryonics stabilization is to arrest metabolism of the patient so that he can be preserved indefinitely until resuscitation and rejuvenation technologies are available. Induction of hypothermia is the principal method employed in cryonics to reduce metabolism, thereby … Continue reading

Fever and brain injury

Elevation of body temperature occurring as a result of hypothalamic coordination of autonomic, neuroendocrine, and behavioral responses in reaction to physiological injury or invasion is generally known as fever. Traditional thought is that the “febrile response” is beneficial in preventing … Continue reading
