Is Society in General Turning its Back on Intellectual Discussion and Scientific Discovery?
Posted by Len Rosen in categories: biotech/medical, existential risks
In our global struggle to deal with COVID-19 and the existential threat that is climate change, there is a growing anti-intellectual, anti-science movement afoot.
Is 21st-century civilization following Rome and China as we turn to disinformation delivered by the technologies science has fostered?

On Longevity Escape Velocity with Aubrey de Grey & Charles Brenner
Posted by Montie Adkins in categories: biotech/medical, life extension
For our inaugural episode of Let’s Talk Longevity, we want to figure out if we are anywhere near Longevity Escape Velocity. Defined as a hypothetical situation in which life expectancy is extended longer than the time that is passing, we decided the best conversation on it would be with its biggest advocate, Dr. Aubrey de Grey, and an equally well-known skeptic of the likelihood of it taking place, Dr. Charles Brenner. This debate did not need hosts!
Join us for the live Q&A on Twitter Spaces this Thursday, May 12th at 12 pm PDT

Cryostasis Revival: The Recovery of Cryonics Patients through Nanomedicine
Posted by Paul Battista in categories: biotech/medical, computing, cryonics, life extension, nanotechnology
Cryostasis Revival by Robert Freitas is the first comprehensive technical exposition how to revive cryonics patients in the future. This 700+ page book with thousands of references, and technical color illustrations, is now available on Amazon in a limited textbook hardcover edition.
Cryostasis is an emergency medical procedure in which a human patient is placed in biological stasis at cryogenic temperatures. A cryopreserved patient can be maintained in this condition indefinitely without suffering additional degradation, but cannot yet be revived using currently available technology. This book presents the first comprehensive conceptual protocol for revival from human cryopreservation, using medical nanorobots. The revival methods presented in this book involve three stages: collecting information from preserved structure, computing how to fix damaged structure, and implementing the repair procedure using nanorobots manufactured in a nanofactory – a system for atomically precise manufacturing that is now visible on the technological horizon.

Retinal Cell Map Could Advance Precise Therapies for Blinding Diseases
Posted by Genevieve Klien in categories: biotech/medical, health, robotics/AI
Researchers have identified distinct differences among the cells comprising a tissue in the retina that is vital to human visual perception. The scientists from the National Eye Institute (NEI) discovered five subpopulations of retinal pigment epithelium (RPE)—a layer of tissue that nourishes and supports the retina’s light-sensing photoreceptors. Using artificial intelligence, the researchers analyzed images of RPE at single-cell resolution to create a reference map that locates each subpopulation within the eye. A report on the research published in Proceedings of the National Academy of Sciences.
“These results provide a first-of-its-kind framework for understanding different RPE cell subpopulations and their vulnerability to retinal diseases, and for developing targeted therapies to treat them,” said Michael F. Chiang, M.D., director of the NEI, part of the National Institutes of Health.
“The findings will help us develop more precise cell and gene therapies for specific degenerative eye diseases,” said the study’s lead investigator, Kapil Bharti, Ph.D., who directs the NEI Ocular and Stem Cell Translational Research Section.

Does Earth Have a Mind and Agency of Its Own?
Posted by Alex Vikoulov in categories: biotech/medical, evolution, neuroscience
Does our planet have a mind and agency of its own? This is one of the main questions philosopher and mystic Oberon Zell illuminates in his latest masterpiece GaeaGenesis: Conception and Birth of the Living Earth. Just as we don’t see a bacterium with a naked eye, we don’t quite seem to have an innate ability to perceive the Gaian mind with a “naked” brain. As Dr. Ralph Metzner, Professor Emeritus of California Institute of Integral Studies and Founder-President of The Green Earth Foundation, writes: “Oberon Zell was the first person to conceive and publish the biological and metaphysical foundations of what has become known as the ‘Gaia Theory’ — the unified body and emergent soul of the living Earth… For over 50 years Oberon has been writing and lecturing on Gaian consciousness, and it is high time that he put it all together into a book!” And, indeed, he did.
The newly-released book takes the idea beyond the metaphorical realm postulated by James Lovelock in his “Gaia Hypothesis” and posits that the entire evolution of life on Earth is the literal embryology of a single vast living being — one replicating continuum of DNA and protoplasm. This distinction has significant implications for the subject of this book: The proposition that Mother Earth is a living, sentient being with a “soul” that humans can perceive if they are aware enough to sense it. In essence, the living beings that populate the Earth are cells within a greater macro-organism.
Here’s one of the revelatory passages from the book: To better understand the planet as a living system, we need to go beyond the time scales of human life to the planet’s own time scale, vastly greater than our own. Looked at in this way, the rhythm of day and night might be the pulse of the planet, one full cycle of every hundred thousand human heartbeats. Speeding up time appropriately, we would see the atmosphere and ocean currents swirling round the planet, circulating nutrients and carrying away waste products, much as the blood circulates nutrients and carries away waste in our own bodies.

Ancient Cave Art in Alabama May Be The Largest Ever Found in North America
Posted by Genevieve Klien in categories: biotech/medical, evolution
New details of our past are coming to light, hiding in the nooks and crannies of the world, as we refine our techniques to go looking for them. Most lauded is the reconstruction of the evolution of humanity since our African origins around 300,000 years ago, by analyzing our living and fossil DNA.
Replete with the ghosts of African and Eurasian populations of the deep past, these have been resurrected only through the ability of science to reach into the world of the minuscule by studying biomolecules.
Now, digital analysis of rock surfaces reveals how other ghosts of the deep past – this time from almost 2,000 years ago in North America – have been coaxed into the light.

Sirtuin 6 : Summary Of Key Points of Professor Cohen Interview | Modern Healthspan
Posted by Montie Adkins in categories: biotech/medical, life extension, media & arts
There is a SIRT6 activator on the market but it is very expensive at a few hundred dollars.
We have had requests for a summary of the interview with Prof Cohen. This video is a summary of the key points from the interviews. As I note in the introduction, this is my interpretation of what Prof Cohen said, please check the original interviews if you have any questions. And please do feel free to let me know if you think I got something wrong!

Longevity Research is an Economic Necessity
Posted by Kelvin Dafiaghor in categories: biotech/medical, genetics, life extension, neuroscience
It is vital to recognize the immediate economic importance of i nvesting in longevity and healthy-aging sciences.
Aging itself is a complex series of at least 300 biological processes involving more than 10% of our genetic makeup. It follows that methods to combat these effects must be a combination of sciences, from biotech to biophysics and pharmaceuticals. There is no single “silver bullet” solution.
Aging, along with the physical and mental decay that accompanies it, is still widely regarded as a natural and inevitable thing. It is not, it is a degenerative disease in which the physical integrity and structure of our cells decay each time they divide to replace old ones or as part of any healing process.
