“Coming Back from the Dead” Is No Longer Science Fiction
Last year, there were widespread reports of a 53-year-old Frenchman who had suffered a cardiac arrest and "died," but was then resuscitated back to life 18 hours after his heart had stopped.
The once black-and-white line between life and death is now blurrier than ever.
This was thought to have been possible in part because his body had progressively cooled down naturally after his heart had stopped, through exposure to the outside cold. The medical team who revived him were reported as being "stupefied" that they had been able to bring him back to life, in particular since he had not even suffered brain damage.
Interestingly, this man represents one of a growing number of extraordinary cases in which people who would otherwise be declared dead have now been revived. It is a testament to the incredible impact of resuscitation science -- a science that is providing opportunities to literally reverse death, and in doing so, shedding light on the age-old question of what happens when we die.
Death: Past and Present
Throughout history, the boundary between life and death was marked by the moment a person's heart stopped, breathing ceased, and brain function shut down. A person became motionless, lifeless, and was deemed irreversibly dead. This is because once the heart stops beating, blood flow stops and oxygen is cut off from all the body's organs, including the brain. Consequently, within seconds, breathing stops and brain activity comes to a halt. Since the cessation of the heart literally occurs in a "moment," the philosophical notion of a specific point in time of "irreversible" death still pervades society today. The law, for example, relies on "time of death," which corresponds to when the heart stops beating.
The advent of cardiopulmonary resuscitation (CPR) in the 1960s was revolutionary, demonstrating that the heart could potentially be restarted after it had stopped, and what had been a clear black-and-white line was shown to be potentially reversible in some people. What was once called death—the ultimate end point— was now widely called cardiac arrest, and became a starting point.
From then on, it was only if somebody had requested not to be resuscitated or when CPR was deemed to have failed that people would be declared dead by "cardiopulmonary criteria." Biologically, cardiac arrest and death by cardiopulmonary criteria are the same process, albeit marked at different points in time depending on when a declaration of death is made.
The apparent irreversibility of death as we know it may not necessarily reflect true irretrievable cellular damage inside the body.
Clearly, contrary to many people's perceptions, cardiac arrest is not a heart attack; it is the final step in death irrespective of cause, whether it be a stroke, a heart attack, a car accident, an overwhelming infection or cancer. This is how roughly 95 percent of the population are declared dead.
The only exception is the small proportion of people who may have suffered catastrophic brain injuries, but whose hearts can be artificially kept beating for a period of time on life-support machines. These people can be legally declared dead based on brain death criteria before their hearts have stopped. This is because the brain can die either from oxygen starvation after cardiac arrest or from massive trauma and internal bleeding. Either way, the brain dies hours or possibly longer after these injuries have taken place and not just minutes.
A Profound Realization
What has become increasingly clear is that the apparent irreversibility of death as we know it may not necessarily reflect true irretrievable cellular damage inside the body. This is consistent with a mounting understanding: it is only after a person actually dies that the cells in the body start to undergo their own process of death. Intriguingly, this process is something that can now be manipulated through medical intervention. Being cold is one of the factors that slows down the rate of cellular decay. The 53-year-old Frenchman's case and the other recent cases of resuscitation after prolonged periods of time illustrate this new understanding.
Last week's earth-shattering announcement by neuroscientist Dr. Nenad Sestan and his team out of Yale, published in the prestigious scientific journal Nature, provides further evidence that a time gap exists between actual death and cellular death in cadavers. In this seminal study, these researchers were able to restore partial function in pig brains four hours after their heads were severed from their bodies. These results follow from the pioneering work in 2001 of geneticist Fred Gage and colleagues from the Salk Institute, also published in Nature, which demonstrated the possibility of growing human brain cells in the laboratory by taking brain biopsies from cadavers in the mortuary up to 21 hours post-mortem.
The once black-and-white line between life and death is now blurrier than ever. Some people may argue this means these humans and pigs weren't truly "dead." However, that is like saying the people who were guillotined during the French Revolution were also not dead. Clearly, that is not the case. They were all dead. The problem is not death; it's our reliance on an outdated philosophical, rather than biological, notion of death.
Death can no longer be considered an absolute moment but rather a process that can be reversed even many hours after it has taken place.
But the distinction between irreversibility from a medical perspective and biological irreversibility may not matter much from a pragmatic perspective today. If medical interventions do not exist at any given time or place, then of course death cannot be reversed.
However, it is crucial to distinguish between biologically and medically: When "irreversible" loss of function arises due to inadequate treatment, then a person could be potentially brought back in the future when an alternative therapy becomes available, or even today if he or she dies in a location where novel treatments can slow down the rate of cell death. However, when true irreversible loss of function arises from a biological perspective, then no treatment will ever be able to reverse the process, whether today, tomorrow, or in a hundred years.
Probing the "Grey Zone"
Today, thanks to modern resuscitation science, death can no longer be considered an absolute moment but rather a process that can be reversed even many hours after it has taken place. How many hours? We don't really know.
One of the wider implications of our medical advances is that we can now study what happens to the human mind and consciousness after people enter the "grey zone," which marks the time after the heart stops, but before irreversible and irretrievable cell damage occurs, and people are then brought back to life. Millions have been successfully revived and many have reported experiencing a unique, universal, and transformative mental state.
Were they "dead"? Yes, according to all the criteria we have ever used. But they were able to be brought back before their "dead" bodies had reached the point of permanent, irreversible cellular damage. This reflects the period of death for all of us. So rather than a "near-death experience," I prefer a new terminology to describe these cases -- "an actual-death experience." These survivors' unique experiences are providing eyewitness testimonies of what we will all be likely to experience when we die.
Such an experience reportedly includes seeing a warm light, the presence of a compassionate perfect individual, deceased relatives, a review of their lives, a judgment of their actions and intentions as they pertain to their humanity, and in some cases a sensation of seeing doctors and nurses working to resuscitate them.
Are these experiences compatible with hallucinations or illusions? No -- in part, because these people have described real, verifiable events, which, by definition are not hallucinations, and in part, because their experiences are not compatible with confused and delirious memories that characterize oxygen deprivation.
The challenge for us scientifically is understanding how this is possible at a time when all our science tells us the brain shuts down.
For instance, it is hard to classify a structured meaningful review of one's life and one's humanity as hallucinatory or illusory. Instead, these experiences represent a new understanding of the overall human experience of death. As an intensive care unit physician for more than 10 years, I have seen numerous cases where these reports have been corroborated by my colleagues. In short, these survivors have been known to come back with reports of full consciousness, with lucid, well-structured thought processes and memory formation.
The challenge for us scientifically is understanding how this is possible at a time when all our science tells us the brain shuts down. The fact that these experiences occur is a paradox and suggests the undiscovered entity we call the "self," "consciousness," or "psyche" – the thing that makes us who we are - may not become annihilated at the point of so-called death.
At New York University, the State University of New York, and across 20 hospitals in the U.S. and Europe, we have brought together a new multi-disciplinary team of experts across many specialties, including neurology, cardiology, and intensive care. Together, we hope to improve cardiac arrest prevention and treatment, as well as to address the impact of new scientific discoveries on our understanding of what happens at death.
One of our first studies, Awareness during Resuscitation (AWARE), published in the medical journal Resuscitation in 2014, confirmed that some cardiac arrest patients report a perception of awareness without recall; others report detailed memories and experiences; and a few report full auditory and visual awareness and consciousness of their experience, from a time when brain function would be expected to have ceased.
While you probably have some opinion or belief about this based upon your own philosophical, religious, or cultural background, you may not realize that exploring what happens when we die is now a subject that science is beginning to investigate.
There is no question more intriguing to humankind. And for the first time in our history, we may finally uncover some real answers.
A ‘Press Release from the Future’ Announces Service for Parents to Genetically Engineer Their Kids
Most people don't recognize how significantly and soon the genetic revolution will transform healthcare, the way we make babies, and the nature of the babies we make. The press release below is a thought experiment today. Within a decade, it won't be. * * *
Genomix Launches uDarwin, a New Business to Help Parents Optimize the Health, Well-Being, and Beneficial Traits of their Future Offspring
NEW YORK, July 29, 2029 /PRMediawire/ -- Genomix, a Caribbean-based health and wellness company, today announced the launch of uDarwin, a discrete, confidential service helping parents select and edit the pre-implanted embryos of their future children.
"Our mission is to help prospective parents realize their dream of parenthood in the safest manner possible while helping them optimize their future children's potential."
"We often fetishize nature," said Genomix Medical Director and Co-Founder Dr. Noam Heller, "but the traditional process of conception through sex confers risks on future children that can be significantly reduced through the careful and safe application of powerful new technologies."
Approximately three percent of all children are born with some type of harmful genetic mutation. Through its patented process of extracting eggs from the prospective mother, fertilizing these eggs with sperm from the intended father or from one of the superstar donor samples in the proprietary uDarwin gene bank, and screening up to twenty of these embryos prior to implantation, this risk can be brought down to under one percent.
"Having a baby is the most intimate and important experience in most people's lives," said Genomix CEO and co-founder Rich Azadian. "Our mission is to help prospective parents realize their dream of parenthood in the safest manner possible while helping them optimize their future children's potential."
In addition to screening pre-implanted embryos to significantly reduce disease risk, uDarwin uses its proprietary algorithm for the "polygenic scoring" of embryos to directionally predict potential future attributes including healthspan, height, IQ, personality style, and other complex genetic traits. Attributes once accepted as being the result of fate or chance can now increasingly be selected by parents from among their own natural embryos using this entirely safe process.
A premium product offering, uDarwin+, provides parents the opportunity to make up to three single gene mutations to their selected embryo to reduce a risk or confer a particular benefit. Among the most popular options for this service include increased resistance to HIV and other viruses, a greater ability to build muscle mass, and enhanced cognition. Additional edits will be made available as the science of human genome editing further advances.
Jamie Metzl's new book, Hacking Darwin: Genetic Engineering and the Future of Humanity, explores how the genetic revolution is transforming our healthcare, the way we make babies, and the nature of and babies we make, what this means for each of us, and what we must all do now to prepare for what's coming.
"uDarwin is proud to be the first company in the world offering the highest level of reproductive choice to parents," Mr. Azadian continued. "Genetic technologies are allowing us for the first time to crack the code of our health and identity. As pioneers in applying the most advanced genetic technologies to human reproduction, we recognize that prospective parents' desire for the services we offer exceeds societal levels of comfort with this technology. Our highest levels of customer service, comfort, and confidentiality ensure parents can secure massive benefits for their future children while avoiding unnecessary attention or any compromise of privacy."
All uDarwin services will be carried out in the company's state-of-the-art clinic aboard a super-luxury 500-foot yacht operating in international waters. After applying on the secure uDarwin website and gaining approval, clients are provided a date, time, and location to meet a company representative at a conveniently located Caribbean marina from where they will be shuttled to the uDarwin clinic. "Pioneers have always traveled beyond boundaries to create new possibilities," Mr. Azadian added. "Conceiving a child in a location where it can receive the greatest benefits of advanced science is no different."
"Pioneers have always traveled beyond boundaries to create new possibilities."
The cost of the basic uDawin service is $5 million, with half paid up front and half paid following the successful birth of a baby. Charges for uDarwin+, premium sperm or egg donors, surrogates, and other services are additional. "uDarwin is not for everyone," Mr. Azadian said, "but most parents of significant means understand that the benefits of optimal genetics far exceed almost any monetary cost."
"The genetic revolution has already begun," Medical Director Heller added. "The question for prospective parents is whether they want to be the last parents who left the health and identity of their future children to chance or the first to give their future children the greatest chance of optimal health and maximal fulfillment in the new reality that will arrive far sooner than most people appreciate."

30 Million People Are Uninsured. New Startup Wants to Connect Them Directly to Doctors.
When Eli Hall was in his thirties, he had a kidney stone that needed surgery. Despite having medical insurance, his out-of-pocket costs for the procedure came to $4,000.
Mira promises that most routine visits will cost around $99 or slightly above.
Hall, an Arizona-based small business owner soon discovered that such costs were proving to be the norm. As a result, he stopped buying insurance altogether. Now he pays in to a subscription-based model of healthcare where $300 per month will get him, his wife, and two children unlimited access (either over the phone or through in-office visits) to doctors in the Redirect Health network. This subscription also meets the Affordable Care Act insurance mandate.
Hall's move away from the traditional insurance care model might have been deliberate, but not everyone is as lucky. In 2018, the Centers for Disease Control and Prevention reported that 30.1 million people under the age of 65 were uninsured in the United States. Now, a new startup called TalktoMira is helping those without insurance access doctors for routine visits — affordably.
The service, accessed through the website (or phone or text), evaluates a user's symptoms and returns recommendations for specific doctors that factor in wait times, traffic conditions, and pricing. Khang T. Vuong, the founder and CEO, expects that doctors will be willing to provide discounts through this model, as they're eliminating the administrative costs associated with the insurance middleman. Some discounts can be as high as 50 percent, according to the website.
Mira promises that most routine visits will cost around $99 or slightly above. "This provides people who can't afford paying $3,000 to $4,000 per year in insurance premiums an alternative to access basic healthcare," Vuong says.
As of press time, Mira is available in the Washington D.C., Northern Virginia, and Dallas, and will soon expand across the country via a partnership with a national network of healthcare providers.
"For those who live in places where we don't have a presence, users can still search for the nearest and least busy urgent cares. The goal is to build a national database of walk-in clinics with straightforward upfront pricing so the 30 million uninsured and 56 million underinsured have access to same or next day primary care at an upfront affordable cost," Vuong says.
Getting Around Traditional Insurance
Mira caters to the uninsured by helping them navigate the healthcare system the moment they need it. "Currently cash patients have to rely mainly on Google for searching for options," Vuong says, adding that patients do also occasionally work with the app ZocDoc for booking. "However [ZocDoc] info has no pricing information; we fill in that much-needed gap," Vuong says. In focus groups TalktoMira conducted, a majority (70 percent) reported cost of service as their main barrier to healthcare.
As Hall's subscription-based model proves, cash-driven access like TalktoMira is not the only option for the uninsured. Direct primary care like the kind that Redirect Health delivers is another way to get around high premiums. It does so by effectively eliminating the administrative costs associated with the middleman, says David Slepak, the director of business development at Redirect. Doctors who are tired of packed schedules and the administrative headaches involved with the insurance model are only too happy to be a part of subscription or cash-based models, explains Vuong.
But TalktoMira and direct primary care models don't resolve the challenges of insurance related to catastrophic events.
James Corbett, Principal at Initium Health, points out the uninsured can also access federally qualified health centers across the country or a free clinic, but these might have problems of long wait times.
"Not a Cure-All"
TalktoMira might not provide the same level of consistency that seeing a primary care doctor does, though Vuong says there are ways to see the same doctor again by choosing them through the system. He adds that TalkToMira also empowers patients by asking them about their satisfaction after the visit and to see if any further checkups might be warranted, thus enabling patients to rate their doctors just like they would any other service provider.
"I might not have one primary care doctor, but I have the entire system behind me," says Hall.
But TalktoMira and direct primary care models don't resolve the challenges of insurance related to catastrophic events. The subscription model won't kick in if the patient has a heart attack and needs to be hospitalized, for example. So patients are also encouraged to purchase a high-deductible, low-premium plan for such contingencies.
"We're spending so much on insurance for the car that we can't afford the gas to drive the car."
Vuong recognizes TalktoMira doesn't solve all the problems related to insurance, but it can at least start by helping to facilitate access to routine visits. Even the insured don't always seek out a doctor because of copays and high deductibles, Slepak says. "We're spending so much on insurance for the car that we can't afford the gas to drive the car," he says.
TalktoMira is hoping that by making routine care accessible, it might both lessen the crunch in emergency rooms where many people don't really belong, and also nip problems in the bud.
"It's not a cure-all, not a panacea," admits Vuong. "It won't get you a knee replacement. But at least I can get you in the system so you might not have to get to that point."
