An interesting paper that uses ALA to shore up telomerase activity, loss of telomeres inhibition of P53 expression and mitochondrial dysfunction in one go. They use ALA (alpha lipoic acid) to induce PGC-1α in this case though PGC1-alpha seems to be a potential target for intervention as I understand that ALA is difficult to deliver to cells. In this case this involves the vascular system and atherosclerosis.

Short telomeres and Mitochondrial dysfunction are increasingly implicated as being closely linked as this 2012 Dephino paper demonstrates in the aging heart:

It’s not every day you get to sit down and have a one-on-one conversation with a United States presidential candidate, let alone one who is also a Transhumanist. TechEmergence recently had the opportunity to do just that during an interview with Zoltan Istvan, the 2016 presidential candidate for the newly formed Transhumanist party and author of the 2013 published The Transhumanist Wager.

If you follow the emerging trends in artificial intelligence, then you have already likely heard of “Transhumanism.” Oxford’s Nick Bostrom, in his 2003 book Ethical Issues for the 21st Century, defined Transhumanism as “a loosely defined movement…that promotes an interdisciplinary approach to understanding and evaluating the opportunities for enhancing the human condition and the human organism opened up by the advancement of technology.”

This philosophy could be a turning point in human evolution. But like all great movements, this one is seemingly slow to pick up a serious following (though perhaps in retrospect, we will comment on how quickly this direction moved society forward). Regardless, Zoltan Istvan is determined to usher in this transitional philosophy as a political player and advocate for human enhancement.

Fighting for Our Lives

How do you get the populace, and other governments, to listen to ideas that, by mainstream standards, buck tradition and fall on the extreme side of the socially-acceptable spectrum?

As regenerative medicine expands, our ability to engineer organs is growing with it. Researchers can now grow a number of so called ‘organoids’ — mini-organs which can teach us more about developmental biology and enable vastly improved testing. In the latest addition to the bunch, a team from Ohio State University has successfully engineered the most complete model yet of a human brain, with a similar maturity to a 5 week old fetus.

Containing 99% of the genes present in the human fetal brain, and about the size of an eraser, the organoid was developed from transformed adult human skin. This method could allow more ethical and precise clinical trials, both speeding up and enabling more rigorous, personalized testing. As animal testing frequently fails to predict varied human responses, these organoid models offer an alternative approach which could revolutionize clinical trial methodology.

“It not only looks like the developing brain, its diverse cell types express nearly all genes like a brain. We’ve struggled for a long time trying to solve complex brain disease problems that cause tremendous pain and suffering. The power of this brain model bodes very well for human health because it gives us better and more relevant options to test and develop therapeutics other than rodents.”

If cancer is predominantly a random process, then why don’t organisms with thousands of times more cells suffer more from cancer? Large species like whales and elephants generally live longer, not shorter lives, so how are they protected against the threat of cancer?

While we have a great deal more to learn when it comes to cancer biology, the general belief is that it arises first from mutation. It’s becoming clear it’s actually an incredibly complicated process, requiring a range of variable factors such as mutation, epigenetic alteration and local environment change (like inflammation). While some students may have spent sleepless nights wondering how many mutated cells they contain after learning the fallibility of our replication mechanisms, the reality is that with such an error rate we should all be ridden with cancer in childhood — but we’re not. Our canine companions sadly often succumb around their 1st decade, but humans are actually comparatively good at dealing with cancer. We live a relatively long time in the mammal kingdom for our size and even in a modern environment, it’s predominantly an age-related disease.

While evolution may have honed replication accuracy, life itself requires ‘imperfection’ to evolve. We needed those occasional errors in germ cells to allow evolution. If keeping the odd error is either preferable or essentially not worth the energy tackling when you’re dealing with tens of trillions of cells, then clearly there is more to the story than mutation. In order to maintain a multi-cellular organism for a long enough period, considering that errors are essentially inevitable, other mechanisms must be in place to remove or quarantine problematic cells.
