Analysis of the mutation dynamics of SARS-CoV-2 reveals the spread history and emergence of RBD mutant with lower ACE2 binding affinity

Posted by in categories: biotech/medical, evolution, genetics

Via Harvard David A. Sinclair “The coronavirus is part bat & part human virus. A new study says the Frankenstein event happened well before its transmission to humans. Wait, what? Humans first infected bats?

The intermediate Frankenstein coronavirus has part human/part bat versions of the spike protein (the knobs on the outside of the virus & what COVID-19 vaccines target). Coronafrankenstein is formally called RaTG13, the name, rank & serial # of a horseshoe bat sample. If we gave bats coronavirus first, then people, including scientists, should stay away from bats especially if they don’t feel well. That’s why, as much as I like cats, I don’t like how they can catch it from us. It’s a potentially vicious cycle.

The new study says a mutation has changed the spike protein of an Indian strain of coronavirus that likely reduces its ability to transmit, but “raises the alarm that the ongoing vaccine development may become futile in future epidemics” like seasonal flu.”

Monitoring the mutation dynamics of SARS-CoV-2 is critical for the development of effective approaches to contain the pathogen. By analyzing 106 SARS-CoV-2 and 39 SARS genome sequences, we provided direct genetic evidence that SARS-CoV-2 has a much lower mutation rate than SARS. Minimum Evolution phylogeny analysis revealed the putative original status of SARS-CoV-2 and the early-stage spread history. The discrepant phylogenies for the spike protein and its receptor binding domain proved a previously reported structural rearrangement prior to the emergence of SARS-CoV-2. Despite that we found the spike glycoprotein of SARS-CoV-2 is particularly more conserved, we identified a mutation that leads to weaker receptor binding capability, which concerns a SARS-CoV-2 sample collected on 27th January 2020 from India. This represents the first report of a significant SARS-CoV-2 mutant, and raises the alarm that the ongoing vaccine development may become futile in future epidemic if more mutations were identified.

The Venus Project Plans to Bring Humanity to the Next Stage of Social Evolution. Here’s How

Posted by in categories: evolution, futurism

Since 1975, Roxanne Meadows has worked with renowned futurist Jacque Fresco to develop and promote The Venus Project. The function of this project is to find alternative solutions to the many problems that confront the world today. She participated in the exterior and interior design and construction of the buildings of The Venus Project’s 21-acre research and planning center.

15 Pictures From The Future Of Human Evolution

Posted by in categories: biological, evolution, transhumanism, wearables

For transhumanists, the possibilities of human interconnectivity via technology is only the beginning of how people may eventually transcend the limitations of their bodies. Photographer David Vintiner and art director Gem Fletcher set out to meet the innovators, artists, and dreamers within the transhumanism movement who are pushing the boundaries of their biology to become something more than human. Their project I Want to Believe consists of three chapters — the first touching on wearable technology, the second on individuals who have made permanent changes to their bodies, and the last on how some transhumanists plan to transcend the human condition.

“Science and human advancement has always been propelled forward by the people who do things differently and those who are not afraid to break the rules.”

Ancient tooth proteins reveal our relation to mysterious human species

Posted by in categories: biotech/medical, evolution

It’s hard to piece together the full history of human evolution from piles of old bones. But now, scientists have made use of a new method to study proteins in dental enamel of an 800,000-year-old human species, helping place it in the family tree.

Although Homo sapiens is the only human species still alive today, the road to get here is paved with extinct relatives. And untangling how they’re all related to each other is a task that scientists continue to wrestle with. The timeline is usually determined through various dating processes, both on the bones themselves and the sediment layers they’re found in. Relationships between species are then determined from this timeline, and by examining the structures and features of the bones to track the progress of evolution.

For the new study, researchers at the University of Copenhagen have used a new tool called palaeoproteomics to get a more precise picture. This involves sequencing proteins from ancient remains, and it works on samples that are far too old to have intact DNA. In this case, the team applied it to the 800,000-year-old teeth of a mysterious, archaic human species called Homo antecessor.

Does relativity lie at the source of quantum exoticism?

Posted by in categories: evolution, particle physics, quantum physics

Since its beginnings, quantum mechanics hasn’t ceased to amaze us with its peculiarity, so difficult to understand. Why does one particle seem to pass through two slits simultaneously? Why, instead of specific predictions, can we only talk about evolution of probabilities? According to theorists from universities in Warsaw and Oxford, the most important features of the quantum world may result from the special theory of relativity, which until now seemed to have little to do with quantum mechanics.

Since the arrival of and the theory of relativity, physicists have lost sleep over the incompatibility of these three concepts (three, since there are two theories of relativity: special and general). It has commonly been accepted that it is the description of quantum mechanics that is the more fundamental and that the theory of relativity that will have to be adjusted to it. Dr. Andrzej Dragan from the Faculty of Physics, University of Warsaw (FUW) and Prof. Artur Ekert from the University of Oxford (UO) have just presented their reasoning leading to a different conclusion. In the article “The Quantum Principle of Relativity,” published in the New Journal of Physics, they prove that the features of quantum mechanics determining its uniqueness and its non-intuitive exoticism—accepted, what’s more, on faith (as axioms)—can be explained within the framework of the . One only has to decide on a certain rather unorthodox step.

Albert Einstein based the special theory of relativity on two postulates. The first is known as the Galilean principle of relativity (which, please note, is a special case of the Copernican principle). This states that physics is the same in every inertial system (i.e., one that is either at rest or in a steady straight line motion). The second postulate, formulated on the result of the famous Michelson-Morley experiment, imposed the requirement of a constant velocity of light in every reference system.
