Did Top Medical Journal Help Cover Up Origins of SARS-CoV-2?


– According to Alina Chan, a molecular biologist at the Broad Institute of Harvard and MIT, SARS-CoV-2 did not evolve in a manner you’d expect, had it jumped from an animal to a human. It sprang into action fully evolved for human transmission
– It appears Nature, a top medical journal, has allowed authors to secretly alter data sets in their papers without publishing notices of correction
– Chan’s investigation reveals authors have renamed samples, failed to attribute them properly, and produced a genomic profile that doesn’t match the samples in their paper. Others are missing data
– RaTG13 — the coronavirus that most resembles SARS-CoV-2, being 96% identical — is actually btCoV-4991, a virus found in samples collected in 2013 and published in 2016
– If SARS-CoV-2, the virus responsible for COVID-19 and the subsequent response to it, came from a lab, then we need to reassess the future of gain-of-function research that allows for the weaponization of viruses

Get ready. This is going to be an important thread. Election season will be over soon and hopefully more people will devote some attention to this… I’m going to walk through a timeline of SARS2-related virus data published in the months after the outbreak. (1/30)

(25 Oct 20)

Since the outbreak in late 2019, events have been unfolding at such a fast pace that it is difficult to keep track of what happened and in what order.

I use visualizations of the timeline to follow key events relating to the search for the animal host of SARS2. (2/30)

Even today, I still hear people saying that SARS-CoV-2 came from pangolins and a Seafood market in Wuhan. I hope this analysis will help to clear things up. It will refresh us on significant early pandemic events and major publications discussing the origins of the virus (3/30).

Scientific history of RaTG13

(Jul 07, 2020)

In early February 2019, Dr. Shi’s team suddenly tossed a brand new genome online and published a paper, citing that hCoV-2019 must come from (horseshoe) Bats because it is so similar to this other sample obtained from Bats in July 2013.

*If an existing genome was already in the system and the new data was uploaded we would expect to see reference notes and that the previous listing had been removed or updated.

*The scientists were forcing an argument that this newly published genome (RaTG13) came from a Bat and is the closest relative to hCoV-2019, therefore our pandemic virus more than likely came from a bat.

At the time of this publication, there is quite literally zero record or publication referencing this sudden new virus that they designated as Bat SL-CoV RaTG13 (Ra being Rhinolophus affinis, 13 being sampling year). How could this new virus have been just ABSENT from the scientific community for SEVEN YEARS?!

In fact, there are (comparatively) barely any Rhinolophus Affinis Samples in our databases. Meaning there is a small pool or Bat viruses from this specific species. The team simply renamed the sample and maybe forgot that 4991 was already in GenBank?! Because 4991 is actually RaTG13, yet this super important publication which was read by all of the top scientists in the world makes zero mention of this important fact.

SARS-CoV-2 is well adapted for humans. What does this mean for re-emergence?

(May 02, 2020)

Abstract: In a side-by-side comparison of evolutionary dynamics between the 2019/2020 SARS-CoV-2 and the 2003 SARS-CoV, we were surprised to find that SARS-CoV-2 resembles SARS-CoV in the late phase of the 2003 epidemic after SARS-CoV had developed several advantageous adaptations for human transmission. Our observations suggest that by the time SARS-CoV-2 was first detected in late 2019, it was already pre-adapted to human transmission to an extent similar to late epidemic SARS-CoV. However, no precursors or branches of evolution stemming from a less human-adapted SARS-CoV-2-like virus have been detected. The sudden appearance of a highly infectious SARS-CoV-2 presents a major cause for concern that should motivate stronger international efforts to identify the source and prevent near future re-emergence.

Boris Johnson hails Oxford vaccine as a ‚triumph for British science‘ and says he is ‚confident this is the year we will defeat coronavirus‘

The initial supplies of Oxford-AstraZeneca vaccine have been produced by a company called Halix in the Netherlands.

Once produced in bulk, the vaccine goes to a plant in Wrexham, run by an Indian company called Wockhardt, where it is decanted into vials in a process known as ‚fill and finish‘. The plant can bottle at least 150,000 doses a day.

How did Covid REALLY spread around the world? As damning test results show antibodies were in US in December – WEEKS before China raised the alarm – growing global evidence points to a cover-up

– Blood samples unveiled this week show people in California, Oregon and Washington infected in December
– Further tests on blood taken in mid-to-late December and into early January found virus in six more states
– Italy, Brazil and France have all since found traces of the virus before China even acknowledged it existed
– Evidence has emerged in Spain and the UK suggesting that Covid-19 was around before testing was possible
– Claims the virus emerged in a market in Wuhan last winter have crumbled in the face of scientific evidence

Covid-19: politicisation, “corruption,” and suppression of science

Science is being suppressed for political and financial gain. Covid-19 has unleashed state corruption on a grand scale, and it is harmful to public health.1 Politicians and industry are responsible for this opportunistic embezzlement. So too are scientists and health experts. The pandemic has revealed how the medical-political complex can be manipulated in an emergency—a time when it is even more important to safeguard science.

The UK’s pandemic response provides at least four examples of suppression of science or scientists. First, the membership, research, and deliberations of the Scientific Advisory Group for Emergencies (SAGE) were initially secret until a press leak forced transparency.

Secrets for Solar Orbiter to solve


The Sun’s magnetic field is responsible for all the solar activity we see; it drives the 11-year ebb and flow in the number of sunspots, and dominates the behaviour of the solar atmosphere. Furthermore, this magnetic field surrounds the entire solar system, creating a giant bubble known as the heliosphere that is filled with electrified gas known as plasma. Disturbances in this plasma can affect the planets, creating aurorae and interfering with the behaviour of technology. Yet the details of the magnetic field’s initial generation inside the Sun are not yet understood.

Periodic variations of solar radiation – a possible source of solar activity-weather effects

(May 1979)

It is suggested that long-lasting co-rotating active longitudes on the Sun may be associated with small variations of the solar radiation reaching the Earth. The oscillations have a basic period of about 27 days and are not expected to have amplitudes greater than 0.1%. They result in a time-varying heat input to the Earth’s continents and, since the land exchanges heat with the overlying atmosphere, this oscillatory heating process generates large-scale planetary waves, mainly of the Rossby-Haurwitz type, in the atmosphere.

The effect of the 11-year solar-cycle on the temperature in the upper-stratosphere and mesosphere: Part II numerical simulations and the role of planetary waves

(July 2005)

The numerical simulations presented here suggest a mechanism by which a small change induced by the solar forcing can generate a large atmospheric response.

Rapid geomagnetic changes inferred from Earth observations and numerical simulations


Rapid changes in field direction have also attracted significant attention, particularly in the context of polarity reversals18. Historically, the fastest directional changes were attributed to lava flows at Steens Mountain, though these results are now thought to be untenable19. Currently, the fastest directional changes noted are those recorded by sediments in central Italy20, where angular changes in the Virtual Geomagnetic Pole position (P^V) reach values of ∂P^V/∂t∼1∘yr−1. These rates are about a factor of 10 faster than values of ∂P^V/∂t∼0.1∘yr−1 for the modern field, similar to the difference in rates of intensity change between the modern field and spikes.

Earth’s magnetic field can change 10 times faster than previously thought


The clearest example of this in their study is a sharp change in the geomagnetic field direction of roughly 2.5 degrees per year 39,000 years ago. This shift was associated with a locally weak field strength, in a confined spatial region just off the west coast of Central America, and followed the global Laschamp excursion — a short reversal of the Earth’s magnetic field roughly 41,000 years ago.

Venus clouds ‚might harbour life‘


„Current theories suggest that Venus and the Earth may have started out alike. There might have been a lot of water on Venus and there might have been a lot of carbon dioxide on Earth,“ Professor Ingersoll explained.

But all that was to change. On Earth, life in the oceans took in carbon dioxide and turned it into limestone. On Venus, 30% closer to the Sun, any oceans boiled away and the water vapour added to the runaway greenhouse effect.

Life in the Clouds of Venus?


WHILE the surface conditions of Venus make the hypothesis of life there implausible, the clouds of Venus are a different story altogether. As was pointed out some years ago, water, carbon dioxide and sunlight—the prerequisites for photosynthesis—are plentiful in the vicinity of the clouds. Since then, good additional evidence has been provided that the clouds are composed of ice crystals at their tops and it seems likely that there are water droplets toward their bottoms. Independent evidence for water vapour also exists5.

Water vapor in the atmosphere of Venus

(December 1972)

Infrared spectra of Venus produced by a Fourier spectrometer flown aboard the NASA CV 990 jet aircraft were analyzed for water-vapor content by comparison with calculated model spectra. The reflecting layer model gave an abundance of 1.6 ± 0.4 μ of precipitable water for the two-way transmission of the Venus atmosphere. The scattering model resulted in a value of 0.25 ± 0.10 μ of water per scattering mean free path.

“This is an astonishing and ‘out of the blue’ finding,” said Sara Seager, a planetary scientist at the Massachusetts Institute of Technology and an author of the papers (one published in Nature Astronomy and another submitted to the journal Astrobiology). “It will definitely fuel more research into the possibilities for life in Venus’s atmosphere.”

Detection of phosphine: new aspects of the phosphorus cycle in the hydrosphere


According to our measurements and calculations, about 5g of phosphorus per day was released as phosphine from an Imhoff tank settling 2,000 m3 per day of raw sewage. Under laboratory conditions, it was also demonstrated that phosphine is released by bacterial reduction from a medium containing inorganic phosphorus.

Phosphine gas in the cloud decks of Venus


Here we report the apparent presence of phosphine (PH3) gas in Venus’s atmosphere, where any phosphorus should be in oxidized forms. Single-line millimetre-waveband spectral detections (quality up to ~15σ) from the JCMT and ALMA telescopes have no other plausible identification.

Meteorite study suggests Earth may have always been wet


A new study finds that Earth’s water may have come from materials that were present in the inner solar system at the time the planet formed — instead of far-reaching comets or asteroids delivering such water.

Earth’s water may have been inherited from material similar to enstatite chondrite meteorites


The origin of Earth’s water remains unknown. Enstatite chondrite (EC) meteorites have similar isotopic composition to terrestrial rocks and thus may be representative of the material that formed Earth. ECs are presumed to be devoid of water because they formed in the inner Solar System. Earth’s water is therefore generally attributed to the late addition of a small fraction of hydrated materials, such as carbonaceous chondrite meteorites, which originated in the outer Solar System where water was more abundant. We show that EC meteorites contain sufficient hydrogen to have delivered to Earth at least three times the mass of water in its oceans.
