US elections 2016: John McAfee and Zoltan Istvan debate cybersecurity, immortality and sexbots
Posted by Zoltan Istvan in categories: geopolitics, life extension, policy, transhumanism
This tongue-in-cheek article highlights an interesting experience I had a few days ago on the Immortality Bus in North Carolina:
One wants to live forever, the other wants to push reset on the US Constitution. Both are running for president in 2016. As Republican and Democrat presidential candidates prepare for December’s debates, pioneering Transhumanist Zoltan Istvan and cybersecurity legend John McAfee met for the first time this week for their own debate, over several large drinks in a motel bar.
Istvan, who is currently touring the US aboard a coffin-shaped campaign bus, and McAfee both have technology at the core of their campaign policies, but in terms of specific policy this is where the similarities end.

The First Human Life Extension Trial
Posted by Roy in categories: biotech/medical, life extension
Last week the FDA announced that they have granted permission for the TAME trial. The Targeting Aging with Metformin (TAME) trial is the first human trial specifically looking at an anti-aging drug in humans.
Repurposing An Old Medicine
Metformin is an old drug, first approved in France in 1957, for the treatment of type 2 diabetes and polycystic ovary syndrome (PCOS). However extracts from the French liliac (Galega officinalis), the plant containing a precursor of metformin, has been used to treat frequent urination, a symptom of diabetes, since the Middle Ages. In 2012 in the US about 60 million prescriptions for metformin were written, making metformin the most used antidiabetic drug. Amazingly, every year about 37,000 metric tons of metformin are produced! Metformin is also a super-cheap drug, costing only cents per dose.

Worm research in life extension leads scientists to discover new metric to track aging

C. elegans roundworm (credit: The Goldstein Lab)
When researchers at The Scripps Research Institute (TSRI) in California administered an antidepressant called mianserin to the Caenorhabditis elegans roundworm in 2007, they discovered the drug increased the lifespan of the “young adulthood” of roundworms by 30–40 per cent.
So, does that mean it will work in humans? Not necessarily. “There are millions of years of evolution between worms and humans,” says TSRI researcher Michael Petrascheck. “We may have done this in worms, but we don’t want people to get the impression they can take the drug we used in our study to extend their own teens or early twenties.”

Gene therapies to reverse human aging – Interview with entrepreneur Elizabeth Parrish
Posted by Shailesh Prasad in categories: biotech/medical, life extension
This article is based on my skype conversation with Elizabeth Parrish, founder and CEO of BioViva. BioViva is a biotech company in the Seattle area focused on developing gene therapies to mitigate the diseases of aging. Liz is currently experimenting these therapies on herself. Her research was recently covered in a MIT Technology Review article and she did an AMA on Reddit you may want to check out.

Scores of Labs Should be Gearing Up to Work on Glucosepane Cross-Link Breakers, But Are They?
Posted by Steve Hill in categories: biotech/medical, chemistry, health, life extension, neuroscience
Glucosepane is one of the most significant mechanisms of aging and yet very few people are working on it!
As we age skin and blood vessels lose their elasticity. People care too much about the skin and too little about the blood vessels, but that is always the way of it. Appearance first and substance later, if at all. Yet you can live inside an aged skin; beyond the raised risk of skin cancer its damaged state arguably only makes life less pleasant, and the present state of medical science can ensure that the numerous age-related dermatological dysfunctions can be kept to a state of minor inconvenience. Loss of blood vessel elasticity, on the other hand, will steadily destroy your health and then kill you. Arterial stiffening causes remodeling of the cardiovascular system and hypertension. The biological systems that regulate blood pressure become dysfunctional as blood vessels depart from ideal youthful behavior, creating a downward spiral of increasing blood pressure and reactions to that increase. Small blood vessels fail under the strain in ever larger numbers, damaging surrounding tissue. In the brain this damage contributes to age-related cognitive decline by creating countless tiny, unnoticed strokes. Ultimately this process leads to dementia. More important parts of the cardiovascular system are likely to fail first, however, perhaps causing a stroke, or a heart attack, or the slower decline of congestive heart failure.
From what is known today, it is reasonable to propose that the two main culprits driving loss of tissue elasticity are sugary cross-links generated as a byproduct of the normal operation of cellular metabolism and growing numbers of senescent cells. Elasticity is a property of the extracellular matrix, an intricate structure of collagens and other proteins created by cells. Different arrangements of these molecules produce very different structures, ranging from load-bearing tissues such as bone and cartilage to elastic tissues such as skin and blood vessel walls. Disrupting the arrangement and interaction of molecules in the extracellular matrix also disrupts its properties. Persistent cross-links achieve this by linking proteins together and restricting their normal range of motion. Senescent cells, on the other hand, secrete a range of proteins capable of breaking down or remodeling portions of the surrounding extracellular matrix, and altering the behavior of nearby cells for the worse.

Transhumanism Solving Violence and Improving the Human Condition: IQ, EQi, and Intelligence Upgrades
Posted by Shailesh Prasad in categories: biotech/medical, business, computing, cyborgs, life extension, neuroscience, robotics/AI, transhumanism
Can we end violence? Can we create greater emotional well being and intellectual equality for the greater well being of humanity? Will we be able to keep up with machines? How can we augment our intelligence? Could we cure mental illness? After advancements in aging the next major area of research from a standpoint of eliminating personal and global suffering would be upgrades in intelligence. Transhumanist values at their core want to eliminate suffering and existential risk to people’s lives. With well founded logic, these goals are not completely out of reach, it is possible but as usual, we will have to take the complex issue from many angles and from the standpoint of a systems engineer, but let’s look at some fun stuff before we get into the heavy stuff.

Telomerase Therapy to Reverse Cardiovascular Senescence
Posted by Steve Hill in categories: biotech/medical, life extension
Exciting news as another group proposes to explore telomerase therapy for the Cardio Vascular system. This no doubt follows on from DePhino et al work on the P53-telomerase-PCG-1 aging axis work which showed the effects of short telomeres on vascular aging (and other organs) and its direct link to Mitochondrial function and Stem cell Decline via the P53-telomerase-PCG-1 aging axis.
