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.
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 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.”
Researchers at Sanford Burnham Prebys Medical Research Institute (SBP) have conclusively identified the protein complex that controls the genes needed to repair skeletal muscle. The discovery clears up deep-rooted conflicting data and will now help streamline efforts towards boosting stem cell-mediated muscle regeneration. Such strategies could treat muscle degenerative diseases such as muscular dystrophies, and those associated with aging and cancer.
The research, published today in eLife, describes the essential role of a TBP-containing TFIID-protein complex in activating genes that regenerate muscle tissue, and shows that an alternative protein called TBP2 is not involved in this task in adult muscles.
“Our discovery clarifies the identity of the ‘molecular switches’ that control the activation of muscle genes in muscle stem cells (MuSCs),” said Barbora Malecova, Ph.D., postdoctoral fellow in the laboratory of Pier Lorenzo Puri, M.D., professor in the Development, Aging and Regeneration Program at SBP, and first author of the article. “Understanding what drives muscle gene expression gives us insights into molecular targets for regenerative medicine-based interventions (drugs) to treat muscle degenerative disorders.”
The Rise of the Rest and Mars Colonization
The Chinese word for crisis has two characters (危機). The first character represents danger and the second can be interpreted as opportunity, change of time, moment or chance. Even though the meaning of these Chinese characters can vary according to the context and nearby characters, the understanding of crisis (危機) as danger (危) plus opportunity (機) can help us think about the challenges faced by humanity in 2030.
In the coming years, China will have the largest economy of the planet, dethroning the USA to number two, both economically and scientifically. India will also be catching up fast as the third largest economy in the world, and its population will continue increasing after overtaking that of China in 2025. The re-emergence of Asia, as represented by China and India, will create a dramatic shift in power and geopolitics from what has been called the West to the East. The international hegemony enjoyed by the West during the last half millennium will move back to the East, which already led the world in many areas before the European Renaissance.
Fortunately, during the next two decades, the world economy will keep expanding and human conditions will get better throughout the whole planet. Indeed, a rising tide lifts all boats. Poverty will be substantially reduced and the environment will be significantly improved thanks to a growing global conscience and continuous advances in technology. Even Africa, the historic cradle of civilization, but considered a basket case during the last few centuries, will experience its own re-emergence in the world stage. After experiencing growth of 5% during the 2010s, and even higher during the 2020s, most African countries will be joining the rapid development of China and India, like most of the rest of the world.
Count of St. Germain; a mystery to still be solved. Ever since I was 7 yrs old, I have found this man as a great mystery. He was a true Renaissance man like Di Vinci; however, know one knew his real age, where he truly came from, and his real story. I hope to pick up my own research again on this man; I have always loved solving puzzles and mysteries.
IS IT POSSIBLE that a man can achieve immortality – to live forever? That is the startling claim of a historical figure known as Count de Saint-Germain. Records date his birth to the late 1600s, although some believe that his longevity reaches back to the time of Christ. He has appeared many times throughout history – even as recently as the 1970s – always appearing to be about 45 years old. He was known by many of the most famous figures of European history, including Casanova, Madame de Pampadour, Voltaire, King Louis XV, Catherine the Great, Anton Mesmer and others. Who was this mysterious man? Are the stories of his immortality mere legend and folklore? Or is it possible that he really did discover the secret of defeating death?
ORIGINS
When the man who first became known as Saint-Germain was born is unknown, although most accounts say he was born in the 1690s. A genealogy compiled by Annie Besant for her co-authored book, The Comte De St. Germain: The Secret of Kings, asserts that he was born the son of Francis Racoczi II, Prince of Transylvania in 1690. Other accounts, taken less seriously by most, say he was alive in the time of Jesus and attended the wedding at Cana, where the young Jesus turned water into wine. He was also said to be present at the council of Nicaea in 325 A.D. What is almost unanimously agreed on, however, is that Saint-Germain became accomplished in the art of alchemy, the mystical “science” that strives to control the elements. The foremost goal of this practice was the creation of “projection powder” or the elusive “philosopher’s stone,” which, it was claimed, when added to the molten form of such base metals as lead could turn them into pure silver or gold. Furthermore, this magical power could be used in an elixir that would impart immortality on those who drank it. Count de Saint-Germain, it is believed, discovered this secret of alchemy.
I have nothing against the idea of designer babies. Why not better ourselves through science? There will always be a baseline version of humanity kicking around, even if it’s in cold storage,thus ensuring that any mistakes made early on don’t destroy the species. Besides, the same technology that allows us to make ourselves better could just as easily be used to repair us if we do make a mistake of some kind. TOO much red-tape, as always.

Recent discoveries and advances in medicine are setting the bioethical world on fire. Some technologies, such as CRISPR-Cas9 and fast DNA sequencing techniques, have tremendously increased our control over our own genome. GMOs, Gene Therapy and life extension are examples of applications of our new gained knowledge in genetics. For more than a few, the thought of scientists playing with the fundamental building blocks of life brings an uneasy feeling. Yet, what are the scientists really doing?
