Mammal brain successfully returned from cryopreservation for the first time

Posted by in categories: biotech/medical, cryonics, life extension, neuroscience

A rabbit’s brain has been successfully returned from long-term cryogenic storage, marking the first time a whole mammalian brain has been recovered in near-perfect condition.

It marks a significant breakthrough in the field of cryonics and boosts the prospect of one day bringing frozen human brains back to life.

Researchers from 21st Century Medicine (21CM) used a new technique called Aldehyde-stabilized cryopreservation that filled the vascular system of the rabbit brain with chemicals that would allow it to be cooled to −211 degrees Fahrenheit (−135 degrees Celsius). When it was thawed, the cell membranes, synapses, and intracellular structures remained intact.

Brain Preservation Breakthrough Could Usher in a New Era in Cryonics

Posted by in categories: biotech/medical, cryonics, life extension, neuroscience

Researchers from 21st Century Medicine have developed a new technique to allow long term storage of a near-perfect mammalian brain. It’s a breakthrough that could have serious implications for cryonics, and the futuristic prospect of bringing the frozen dead back to life.

By using a chemical compound to turn a rabbit’s brain into a near glass-like state, and then cooling it to −211 degrees Fahrenheit (−135 degrees Celsius), a research team from California-based 21st Century Medicine (21CM) showed that it’s possible to enable near-perfect, long-term structural preservation of an intact mammalian brain. The achievement has earned not just accolades from the scientific community, but a prestigious award as well; the 21CM researchers are today being awarded the $26,735 Small Mammal Brain Preservation Prize, which is run by the Brain Preservation Foundation (BPF).

The Small Mammal Brain Preservation Prize Has Been Won

Posted by in categories: biotech/medical, cryonics, life extension, neuroscience

The Brain Preservation Foundation (BPF) announced that the Small Mammal Brain Preservation Prize has officially been won. The spectacular result achieved by 21st Century Medicine researchers provides the first demonstration that near-perfect, long-term structural preservation of an intact mammalian brain is achievable.

A team from 21st Century Medicine, spearheaded by recent MIT graduate Robert McIntyre, has discovered a way to preserve the delicate neural circuits of an intact rabbit brain for very long-term storage using a combination of chemical fixation and cryogenic cooling. Proof of this accomplishment, and the full “Aldehyde-Stabilized Cryopreservation” (ASC) protocol, was recently published in the journal Cryobiology and has been independently verified by the BPF through extensive electron microscopic examination conducted by the two official judges of the prize: BPF President Ken Hayworth and Princeton neuroscience professor Sebastian Seung, author of “Connectome: How the Brain’s Wiring Makes Us Who We Are.”

“Every neuron and synapse looks beautifully preserved across the entire brain,” said Hayworth. “Simply amazing given that I held in my hand this very same brain when it was frozen solid… This is not your father’s cryonics.”

Official Alcor Statement Concerning Marvin Minsky

Posted by in categories: cryonics, law, life extension, nanotechnology

The legal death of Marvin Minsky was publicly reported on Monday, January 25, 2016. There has been speculation on the part of numerous individuals and publications that he may have been cryopreserved by Alcor. This notice is Alcor’s formal response to inquiries on this issue.

In a public ceremony at the Extro-3 conference in 1997, nanotechnology pioneer Eric Drexler presented Prof. Minsky with a bracelet given to all new Alcor members. This bracelet provides emergency contact information and basic instructions. Minsky has spoken publicy many times about his advocacy of overcoming aging and the inevitability of death and about cryonics (human cryopreservation) as a last resort. He was also among the 67 signatories of the Scientists Open Letter on Cryonics and a member of Alcor’s Scientific Advisory Board. This much is public knowledge. None of this necessarily means that Prof. Minsky had cryopreservation arrangements at the time of legal death. Alcor neither confirms nor denies whether Prof. Minsky had such arrangements.

Alcor’s official response may puzzle some readers, so we would like to point out the privacy options that have been and currently are available to our members. When a member signs up for cryopreservation by Alcor, they have four options:

Company Aims To Bring Back The Dead Within 30 Years

Posted by in categories: cryonics, life extension, nanotechnology, robotics/AI

Humai, a Los Angeles-based tech company, is hoping to bring back the dead within 30 years. A Los Angeles-based technology company has a goal of bringing dead people back to life within the next 30 years. Humai’s official website states that artificial intelligence and nanotechnology are being used to analyze human processes, and the creation of “an artificial body” is in the works. Once the artificial body has been perfected, the member’s brain, which will have been preserved through cryonics after death, will be implanted to direct movement and function. Helping the integration will be the extensive information the company gained while tracking each person for years during his or her life, according to the company’s founder and CEO Josh Bocanegra. An artificial intelligence app will retain the voice, personality, and behavioral patterns of each person and deploy as needed. This app is expected to launch among the membership by 2017. Aiding in this pursuit is the nanotechnology Humai is assisting in developing, which “will repair the cells destroyed in the brain after death.” The company, which employs five people total, is thus far self-funded but may be open to investments in the near future.

Cryonics Is No Fantasy, Should We Be Taking It Seriously?

Posted by in categories: cryonics, life extension, materials, neuroscience

Most science starts off at the fringe and slowly makes it way to the mainstream. Cryopreservation is commonly achieved in a laboratory setting, but for many years serious applications remained confined to science fiction. Is it time to change how we see cryonics?

The science of freezing things

Scientific research requires great storage, and huge amounts of material including cells are frozen every day to be used at the later date. If you follow the correct protocols, many forms of life can be re-awakened after their cryogenic sleep. DMSO, propylene glycol and glycerol help abolish problems like ice crystals which can rupture cells, and storage temperatures can drop to below −120 °C. At these levels biological reactions are essentially halted.

Scientists’ Open Letter on Cryonics

Posted by in categories: biotech/medical, cryonics, health, life extension, neuroscience

To whom it may concern,

Cryonics is a legitimate science-based endeavor that seeks to preserve human beings, especially the human brain, by the best technology available. Future technologies for resuscitation can be envisioned that involve molecular repair by nanomedicine, highly advanced computation, detailed control of cell growth, and tissue regeneration.

With a view toward these developments, there is a credible possibility that cryonics performed under the best conditions achievable today can preserve sufficient neurological information to permit eventual restoration of a person to full health.
