One in five Americans wants to live forever

Posted by in categories: life extension, materials

While it might not be quite as big a concern, the environmental impact of death care is also something Americans are paying attention to. Around four in ten (41%) Americans are somewhat or very concerned about the environmental impact of traditional burial methods.

On a similar note, 45% agreed with the statement, “People need to rethink the way we currently deal with ‘death care’ in regard to the environment.” And 11% said that they would like to have a green burial with shrouds and biodegradable material after they die.

Some of the possible environmental impacts of a traditional burial include embalming fluid leaking into the soil, large amounts of water being used for cemetery maintenance, and wood and metal caskets leaving behind toxic residue.

A high-carb diet may explain why Okinawans live so long

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

A very good article on the studies on centenarians of Okinawa, on the importance of carbohydrate / protein ratio in diet, genes, calorie restriction and more: “… Genetic good fortune could be one important factor. Thanks to the geography of the islands, Okinawa’s populations have spent large chunks of their history in relative isolation, which may has given them a unique genetic profile. Preliminary studies suggest this may include a reduced prevalence of a gene variant – APOE4 – that appears to increase the risk of heart disease and Alzheimer’s. They may also be more likely to carry a protective variant of the FOXO3 gene involved in regulating metabolism and cell growth. This results in a shorter stature but also appears to reduce the risk of various age-related diseases, including cancer. Even so, it seems unlikely that good genes would fully explain the Okinawans’ longevity, and lifestyle factors will also be important…”


Emerging evidence suggests a 10:1 ratio of carbohydrates to proteins may protect the body from the ravages of ageing.

Gum Disease Bacteria May Contribute to Alzheimer’s Disease

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

The complex relationship between the microbiome and the rest of the body has only recently started to become truly appreciated. The bacteria of the gut are increasingly looking like a potential player in aging, and some bacteria in the mouth associated with chronic periodontitis may be linked to Alzheimer’s disease [1].

University of Louisville researcher Jan Potempa from the Department of Oral Immunology and Infectious Diseases in the School of Dentistry led a team of scientists in a new study, which demonstrated that the bacteria Porphyromonas gingivalis (P. gingivalis), the main pathogen involved in chronic periodontitis, is also found in the brains of Alzheimer’s disease patients. Chronic periodontitis is a common oral disease that is characterized by the chronic inflammation of periodontal tissues, which is provoked by the accumulation of excessive dental plaque.

It has been suggested before that there may be an infectious element to Alzheimer’s disease, but, until recently, the evidence has been limited [2]. These researchers suggest that their study is strong evidence for a connection between the presence of P. gingivalis and the onset of Alzheimer’s disease.

Teaching human cells to clean house to delay aging and fight neurodegeneration

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

Monash researchers have unlocked a key process in all human cells that contributes to diseases like cancer and neurodegenerative diseases as well as ageing. The discovery reveals how cells efficiently get rid of cellular junk, which when it accumulates, can trigger death and the health problems associated with getting older.

Autophagy is the ‘clean-up crew’ of the cell—used by cells to break-down debris like broken proteins, bits of cell , viruses or bacteria. To capture this trash, cells use specialised membranes to trap the cargo for recycling into new parts and energy. Without efficient autophagy cells become choked by their own damaged components, which can contribute to the development of a range of diseases, including diabetes, muscular dystrophy, Parkinson’s and Alzheimer’s disease.

Dr. Michael Lazarou’s laboratory from the Monash Biomedicine Discovery Institute have today published data in Nature Communications that debunks previously held beliefs about how cells target their trash. Cells target different types of cargo by using ‘autophagy receptors’, which can bind the cargo as well as the ensnaring membranes. Until recently these autophagy receptors were thought to recruit the membranes to the cargo, but research led by Dr. Benjamin Padman from the Lazarou lab now shows that this is not the case.

Steve Perry presents GDF11 with an Age Reversal update

Posted by in categories: biotech/medical, life extension

GDF11 is an endogenous (meaning it’s natural, and you have it in you) signaling molecule whose primary mechanism of action is stem cell DNA repair. Most of the aging is likely caused by the atrophy of your stem cell populations due to declining GDF11 levels, and many believe this is natural selection’s way of programming lifespan. Fortunately, adding exogenous GDF11 can generally repair enough of senescent stem cells to reverse your age 5 to 10 years.

Steve will take some time providing information on the topic and answering questions.

Machine Learning and Medicine: Is AI the Future of Psychiatry?

Posted by in categories: bioengineering, biotech/medical, life extension, robotics/AI

Artificial intelligence, or AI is something we hear a lot about today. In this interview with Life.

Extension’s Michael A. Smith, MD, Kristen Willeumier, PhD, provides some insight into AI technology and its relationship with psychiatry which, along with neurology, studies and treats diseases of the brain. Dr. Smith predicts that AI will soon be an important part of how we understand and treat disease. According to Dr. Willeumier, some of that technology is now “ready for prime time.” Download this Live Foreverish podcast episode for FREE on iTunes!

Artificial intelligence is, simply, the intelligence of machines as opposed to human or animal intelligence. According to the New World Encyclopedia™, “Artificial intelligence (AI) is a branch of computer science and engineering that deals with intelligent behavior, learning, and adaptation in machines. John McCarthy coined the term to mean ‘the science and engineering of making intelligent machines.’”.

Meanwhile, in the 1600s…

Posted by in categories: biotech/medical, life extension

Many people are at the very least iffy about the idea of extending human healthy lifespan through medical biotechnologies that prevent age-related diseases essentially by rejuvenating the body. Even people who accept the possibility that such therapies can be developed are not convinced that developing them is a good idea, and there are only a few arguments that most people use. These arguments can actually be easily adapted to make a case against the medicine that already exists, which the vast majority of people on the planet currently benefit from—and the consensus is virtually universal that people who do not yet benefit from it should be given this opportunity as soon as possible.

The question is: would people who accept these arguments as valid objections to rejuvenation accept them also as valid objections against “normal” medicine? For example, how many present-day people would agree with what these two people from the 1600s are talking about?

Timeline of cryonics

Posted by in categories: cryonics, life extension, neuroscience

This is a timeline of cryonics.

Cryonics is the attempt to preserve a human or non-human animal using low-temperature with the hope that partial or complete resuscitation may be possible in the future.

While cryonics is currently the most popular brain preservation method, other methods are being used and developed, notably plastination. This page treats about all brain preservation methods.

In surprising reversal, scientists find a cellular process that stops cancer before it starts

Posted by in categories: biotech/medical, life extension

Just as plastic tips protect the ends of shoelaces and keep them from fraying when we tie them, molecular tips called telomeres protect the ends of chromosomes and keep them from fusing when cells continually divide and duplicate their DNA. But while losing the plastic tips may lead to messy laces, telomere loss may lead to cancer.

Salk Institute scientists studying the relationship of telomeres to cancer made a surprising discovery: a cellular recycling process called autophagy—generally thought of as a —actually promotes the death of cells, thereby preventing cancer initiation.

The work, which appeared in the journal Nature on January 23, 2019, reveals autophagy to be a completely novel tumor-suppressing pathway and suggests that treatments to block the process in an effort to curb cancer may unintentionally promote it very early on.
