    • expert reaction to people who think 5G causes coronavirus April 4, 2020 There have been reports of  people who think 5G mobile networks have caused the coronavirus outbreak. Prof Malcolm Sperrin, Director of the Department of Medical Physics and Clinical Engineering, Oxford University Hospitals NHS Trust, said: “There is no sensible link between the use of 5G frequencies and COVID-19 or any other biological virus or bacteria.  This sort of conjecture only contributes to the risk to individuals who are prepared to believe such non-science as opposed to the considerable efforts being made by medical science to enable the population to protect themselves in an informed manner.  “The energy of the 5G wave is insufficient to break bonds and hence it is called ‘non-ionising’ as opposed to ‘ionising’ radiation such as X-rays.  Furthermore, the intensity transmitted from the masts is extremely low.  The risk from jeopardising a means of communication at the current time is of concern and is entirely unwarranted. “The supposed correlation between 5G and its development in China reveals a complete lack of understanding of the difference between cause and coincidence.  In the simplest terms there might have been a train leaving Wuhan station during 5G development, but the train departure was not caused by 5G.” Dr Simon Clarke, Associate Professor in Cellular Microbiology, University of Reading, said: “The idea that COVID19 is caused by 5G mobile phone signals is complete rubbish.  This is a disease which numerous doctors and scientists around the world have said is caused by a virus, something completely different to a mobile phone signal.  “Viruses are tiny particles made up of genetic material, wrapped in a layer of proteins and fats.  They have no metabolism and can’t reproduce without causing an infection.  In the case of this coronavirus, it infects cells in human lungs in order to replicate, damaging them and also causing a harmful immune reaction in the process.  5G radio signals are electromagnetic waves, very similar to those already used by mobile phones.  Electromagnetic waves are one thing, viruses are another, and you can’t get a virus off a phone mast.” Prof Adam Finn, Professor of Paediatrics, University of Bristol, said:  “The present epidemic is caused by a virus that is passed from one infected person to another. We know this is true. We even have the virus growing in our lab, obtained from a person with the illness. Viruses and electromagnetic waves that make mobile phones and internet connections work are different things. As different as chalk and cheese. The internet connections these networks give us are one of the most important tools we are using to coordinate our response to the epidemic and efforts to do research to overcome it. Damaging phone masts is like knocking holes in your lifeboats while your ship sinks.” Dr Michael Head, Senior Research Fellow in Global Health, University of Southampton, said: “Virus experts have looked at the genetic code of the virus to track its origins. Epidemiologists have tracked the spread of the virus around the world, identifying risk factors to advise policy. Diagnostics researchers are developing tests to identify those with the infection and those who have been infected. Collectively, we know how infectious diseases spread. Scientific papers are published, new knowledge is generated. That is what experts do. “Conspiracy theorists are a public health danger who once read a Facebook page. Anti-vaccination activists have consistently shown their capabilities to harm child health with numerous baseless claims. Here, we also see similar groups of people keen to show their ignorance on a topic where they have no helpful expertise, nor any inclination to post useful public health messages. The celebrities fanning the flames of these conspiracy theorists should be ashamed. They have large followings and thus a mandate to act responsibly. They may have noticed that there’s currently a pandemic going on. Now is a very good time indeed to listen to the experts on infectious disease epidemiology and public health.” Prof Brendan Wren, Professor of Microbial Pathogenesis, London School of Hygiene & Tropical Medicine, said: “There is no scientifically credible evidence to link the introduction of 5G masts with the COVID-19 outbreak. This would be both a physical and biological impossibility.” All our previous output on this subject can be seen at this weblink: www.sciencemediacentre.org/tag/covid-19 Declared interests None received.
    • You know how charitable organizations work right? Least you see Ravi's books.  Which group do you recommend we support? Can we see their books?
    • Came across this video on youtube.   
    • Fair enough. I do enjoy a good conspiracy! 😁😅
    • The coronavirus did not escape from a lab. Here's how we know. By Jeanna Bryner - Live Science Editor-in-Chief 15 days ago   Viruses like the novel coronavirus are shells holding genetic material. (Image: © Andriy Onufriyenko/Getty Images) As the novel coronavirus causing COVID-19 spreads across the globe, with cases surpassing 284,000 worldwide today (March 20), misinformation is spreading almost as fast.  One persistent myth is that this virus, called SARS-CoV-2, was made by scientists and escaped from a lab in Wuhan, China, where the outbreak began. A new analysis of SARS-CoV-2 may finally put that latter idea to bed. A group of researchers compared the genome of this novel coronavirus with the seven other coronaviruses known to infect humans: SARS, MERS and SARS-CoV-2, which can cause severe disease; along with HKU1, NL63, OC43 and 229E, which typically cause just mild symptoms, the researchers wrote March 17 in the journal Nature Medicine. "Our analyses clearly show that SARS-CoV-2 is not a laboratory construct or a purposefully manipulated virus," they write in the journal article.  Related: 13 coronavirus myths busted by science Kristian Andersen, an associate professor of immunology and microbiology at Scripps Research, and his colleagues looked at the genetic template for the spike proteins that protrude from the surface of the virus. The coronavirus uses these spikes to grab the outer walls of its host's cells and then enter those cells. They specifically looked at the gene sequences responsible for two key features of these spike proteins: the grabber, called the receptor-binding domain, that hooks onto host cells; and the so-called cleavage site that allows the virus to open and enter those cells.  That analysis showed that the "hook" part of the spike had evolved to target a receptor on the outside of human cells called ACE2, which is involved in blood pressure regulation. It is so effective at attaching to human cells that the researchers said the spike proteins were the result of natural selection and not genetic engineering. The Coronavirus Did Not Escape From A Lab. Here's How We Know. The persistent myth can be put to bed. Here's why: SARS-CoV-2 is very closely related to the virus that causes severe acute respiratory syndrome (SARS), which fanned across the globe nearly 20 years ago. Scientists have studied how SARS-CoV differs from SARS-CoV-2 — with several key letter changes in the genetic code. Yet in computer simulations, the mutations in SARS-CoV-2 don't seem to work very well at helping the virus bind to human cells. If scientists had deliberately engineered this virus, they wouldn't have chosen mutations that computer models suggest won't work. But it turns out, nature is smarter than scientists, and the novel coronavirus found a way to mutate that was better — and completely different— from anything scientists could have created, the study found.  Another nail in the "escaped from evil lab" theory?  The overall molecular structure of this virus is distinct from the known coronaviruses and instead most closely resembles viruses found in bats and pangolins that had been little studied and never known to cause humans any harm.  "If someone were seeking to engineer a new coronavirus as a pathogen, they would have constructed it from the backbone of a virus known to cause illness," according to a statement from Scripps.  Where did the virus come from? The research group came up with two possible scenarios for the origin of SARS-CoV-2 in humans. One scenario follows the origin stories for a few other recent coronaviruses that have wreaked havoc in human populations. In that scenario, we contracted the virus directly from an animal — civets in the case of SARS and camels in the case of Middle East respiratory syndrome (MERS). In the case of SARS-CoV-2, the researchers suggest that animal was a bat, which transmitted the virus to another intermediate animal (possibly a pangolin, some scientists have said) that brought the virus to humans. Related: 20 of the worst epidemics and pandemics in history In that possible scenario, the genetic features that make the new coronavirus so effective at infecting human cells (its pathogenic powers) would have been in place before hopping to humans. In the other scenario, those pathogenic features would have evolved only after the virus jumped from its animal host to humans. Some coronaviruses that originated in pangolins have a "hook structure" (that receptor binding domain) similar to that of SARS-CoV-2. In that way, a pangolin either directly or indirectly passed its virus onto a human host. Then, once inside a human host, the virus could have evolved to have its other stealth feature — the cleavage site that lets it easily break into human cells. Once it developed that capacity, the researchers said, the coronavirus would be even more capable of spreading between people. All of this technical detail could help scientists forecast the future of this pandemic. If the virus did enter human cells in a pathogenic form, that raises the probability of future outbreaks. The virus could still be circulating in the animal population and might again jump to humans, ready to cause an outbreak. But the chances of such future outbreaks are lower if the virus must first enter the human population and then evolve the pathogenic properties, the researchers said.
