EXCLUSIVE: COVID-19 ‚has NO credible natural ancestor‘ and WAS created by Chinese scientists who then tried to cover their tracks with ‚retro-engineering‘ to make it seem like it naturally arose from bats, explosive new study claims

– An explosive new study claims researchers found ‚unique fingerprints‚ in COVID-19 samples that they say could only have arisen from manipulation in a laboratory

– DailyMail.com exclusively obtained the new 22-page paper authored by British Professor Angus Dalgleish and Norwegian scientist Dr. Birger Sørensen set to be published in the Quarterly Review of Biophysics Discovery

– The study showed there’s evidence to suggest Chinese scientists created the virus while working on a Gain of Function project in a Wuhan lab

– Gain of Function research, which was temporarily outlawed in the US, involves altering naturally-occurring viruses to make them more infectious in order to study their potential effects on humans
According to the paper, Chinese scientists took a natural coronavirus ‚backbone‘ found in Chinese cave bats and spliced onto it a new ’spike‘, turning it into the deadly and highly transmissible COVID-19

– The researchers, who concluded that COVID-19 ‚has no credible natural ancestor‚, also believe scientists reverse-engineered versions of the virus to cover up their tracks.

‚We think that there have been retro-engineered viruses created,‘ Dalgleish told DailyMail.com. ‚They’ve changed the virus, then tried to make out it was in a sequence years ago.‘

How Nanotechnology Helped Create mRNA COVID-19 Vaccines

(04.12.2020)

Vaccines that employ mRNA were in early development before COVID-19 brought the world to its knees, and nanotech has been central to these efforts — unsurprisingly, as viruses are just naturally occurring nanoparticles themselves.

The key to making effective nanoparticle vaccines, and medicines in general, lies in mimicking the natural behaviors and tricks that make viruses so successful, and dangerous, in the first place.

Fact check: Lipid nanoparticles in a COVID-19 vaccine are there to transport RNA molecules

False. The lipid nanoparticles in the Pfizer-BioNTech COVID-19 vaccine protect and transport the vaccine component. They do not contain little computers or robots.

Video shares false claim that Pfizer-BioNTech Covid-19 vaccine contains ’nanotechnology‘

A video viewed thousands of times in multiple posts on Facebook claims Pfizer-BioNTech’s Covid-19 mRNA vaccine contains lipid nanoparticles that could be concealing „little computers”. The claims are false; nanoparticles are microscopic particles that measure less than 100 nanometres, which have no relation to nanocomputers; an infectious diseases expert told AFP no technology currently exists by which computers could be inserted into an mRNA vaccine.

Genome editing wins Nobel chemistry prize

Her work showed that tracrRNA is part of the organism’s immune defences.

This system, known as CRISPR/Cas, disarms viruses by cleaving their DNA.

In 2011, the same year she published this work, Charpentier began a collaboration with Doudna to recreate the bacterium’s genetic scissors in a test tube. They also worked on simplifying the scissors‘ molecular components so they were easier to use.

Researchers assumed CRISPR-mediated disruption of genes was turning them off – but they were wrong

A new study reveals yet another major unintended effect from the CRISPR-Cas9 gene editing tool – with potentially serious implications for the food safety of gene-edited plants. The study found that CRISPR-Cas9 edits intended to knockout the function of a gene fail to do so. Instead, proteins are still produced from the damaged genes, many of which are still functional. The result could be the production of gene-edited plants that are toxic or allergenic.

Gene-editing damages DNA more than previously thought: study

They found „large genetic rearrangements such as DNA deletions and insertions“ in cells, which could lead to important genes being switched on or off and causing dangerous changes.

The research also showed that standard tests do not pick up damage to DNA caused by CRISPR-Cas9.

Experts not involved in the study said it was unclear how such large, unintended changes were not noticed before.

CRISPR/Cas-Methode

Die CRISPR/Cas-Methode (Clustered Regularly Interspaced Short Palindromic Repeats) ist eine biochemische Methode, um DNA gezielt zu schneiden und zu verändern (Genome Editing). Gene können mit dem CRISPR/Cas-System eingefügt, entfernt oder ausgeschaltet werden,[1] auch Nukleotide in einem Gen können geändert werden.[2]

Kein CRISPR bei Demeter

Gentechnisch veränderte Pflanzen haben in der Bio-Landwirtschaft nichts zu suchen – auch dann nicht, wenn es um ganz neue Gentech-Verfahren wie CRISPR/Cas, Zinkfingernuklease-Technik oder Oligonukleotid-gesteuerte Mutagenese geht. Daran ließen die Delegierten des Anbauverbandes Demeter bei ihrer jährlichen Versammlung keinen Zweifel.

Chinese scientists are changing what it means to be human. We need to think about the downsides.

Still, this experiment and last year’s are a proof of concept: CRISPR could be used to introduce desired genetic mutations into a human embryo. And if that embryo was viable and was implanted into a uterus and carried to term, the resulting child would be something out of science fiction: a genetically-enhanced human being.
