U.S. Transhumanist Party Virtual Meeting and Q&A – Saturday, February 23, 2019, at 6 p.m. U.S. Pacific Time. Join us for an extensive 2-hour discussion! Watch it and view the agenda here:
The U.S. Transhumanist Party invites many of its Officers and Ambassadors to discuss recent activities and plans for 2019, including the upcoming Presidential nomination process. The meeting will include a question-and-answer portion where inquiries from members and the general public will be addressed.
Agenda
Foreword to the Syntellect Hypothesis.
I had the honour of writing the foreword of Alex Vikoulov’s recently published masterpiece and bestseller “The Syntellect Hypothesis”. Hereunder you can read my foreword:
“If you picked up this book, it is not unlikely that you may have heard of the early 20th century philosophical movement of Cosmism. This movement, which originated in Russia, was striving for conquering the planets and stars, for radical life extension, immortality and resurrection of our loved ones by the means of technology. Perhaps one of its most important pioneers was Konstantin Tsiolkovsky, whose aspirations did not only venture into the realm of the Macro, but also explored the Micro. He spoke of the atomic world as being animated and can thus be considered a kind of cosmist-panpsychist.
The foundational work of the cosmic aspirations of man by the Russian Cosmists soon reverberated through the intellectual world of the early 20th century and found a resonance and fertile ground in the works of Pierre Teilhard de Chardin. Teilhard saw evolution as having a direction, namely the direction of concentrating consciousness in form, striving towards accumulation of knowledge, which gradually is attained by the formation of the Noosphere and which will culminate in the apotheosis of the Omega Point. Teilhard de Chardin considered that Omega Point is not necessarily merely a future construct, but in a sense is already here as the ”Great Presence.” Thus, his pantheism is more panentheism in which God has both an immanent and transcendent aspect.
Researchers in the US have built an “alien” DNA system from eight building block letters, so expanding the genetic code from four and doubling its information density. The new system meets all of the requirements for Darwinian evolution and can also be transcribed to RNA. It will be important for future synthetic biology applications and expands the scope of molecular structures that might be capable of supporting life, both here on Earth and more widely in the universe.
One of the main characteristics of life is that it can store and pass on genetic information. In modern-day organisms, this is done by DNA using just four building blocks: guanine, cytosine, adenine and thymine (G, A, C and T). Pairs of DNA strands form a double helix with A bonding to T and C bonding to G.

A black, thumb-sized missile sails through the jungle air, a thunderous buzzing announcing its arrival. The massive insect lands heavily on a tree-bound termite nest, taking a moment to fold its brassy wings and stretch its humongous, curved jaws. This is Wallace’s giant bee, the beefiest and bumbliest bee on Earth. After going missing for nearly four decades, the species has just been rediscovered in its native Indonesia.
Wallace’s giant bee (Megachile pluto) gets its name from its original discoverer, Alfred Russel Wallace, the British naturalist famous for independently conceiving the theory of evolution through natural selection alongside Charles Darwin. Wallace collected the bee while on an expedition in Indonesia’s North Moluccas islands in 1858, describing it as a “large black wasp-like insect, with immense jaws like a stag-beetle.” The tiny titan then went more than a century without being spotted by Western scientists, only seen again by entomologist Adam Messer in 1981, who was able to observe some of its behavior on a number of small islands. But since then, no one had documented any encounters with the huge bee.

Firstly, it greatly depends on how you define immortality. If you define it as living forever and being indestructible as in a comic book, then, no, it is highly unlikely. However, if you define it in terms of showing no decline in survival characteristics, no increase in disease incidence and no increase in mortality with advancing age, then yes. The first is a science-fiction fantasy; the second is based on real-world biology that evolution has already selected for in certain species. We call this state negligible senescence.
Senescence and negligible senescence
Senescence refers to the gradual deterioration of aging and is typically very obvious in almost every species. More accurately, senescence refers to a decline of survival characteristics, such as strength, mobility, senses, and age-related increases in mortality along with a decrease in reproductive capability. Mortality rates for humans and most animals increase dramatically with age beyond reaching reproductive maturity.

Scientists have discovered that grasses are able to short cut evolution by taking genes from their neighbours. The findings suggest wild grasses are naturally genetically modifying themselves to gain a competitive advantage.
Understanding how this is happening may also help scientists reduce the risk of genes escaping from GM crops and creating so called super-weeds—which can happen when genes from GM crops transfer into local wild plants, making them herbicide resistant.
Since Darwin, much of the theory of evolution has been based on common descent, where natural selection acts on the genes passed from parent to offspring. However, researchers from the Department of Animal and Plant Sciences at the University of Sheffield have found that grasses are breaking these rules. Lateral gene transfer allows organisms to bypass evolution and skip to the front of the queue by using genes that they acquire from distantly related species.
