A Canadian company has developed a wall-mounted device it claims can detect the presence of coronavirus in the air, and send an alert.#science #medicine #health #Covid-19 #CoronaVirus #pandemic
Kontrol Energy hopes its BioCloud devices could be used in hospitals, transport systems and schools - but has no orders as yet.
One expert, who independently tested the system, said he believed it worked.
But another told the BBC it would need many more tests before he was convinced of its efficacy.
Its makers say the BioCloud device could be installed in schools and offices to issue alerts.www.bbc.co.uk

Leaked documents reportedly show the government plans to carry out up to 10 million coronavirus tests a day by early next year, but critics say the proposals represent "waste/corruption on a cosmic scale".#science #medicine #health #Covid-19 #CoronaVirus #pandemic #UK #politics #corruption
The government's scientific advisory group earlier said mass testing could lead to a large number of false positive results.

The world-altering coronavirus behind the COVID-19 pandemic is thought to be just 60 nanometres to 120 nanometres in size. This is so mind bogglingly small that you could fit more than 400 of these virus particles into the width of a single hair on your head. In fact, coronaviruses are so small that we can’t see them with normal microscopes and require much fancier electron microscopes to study them.

We overuse pesticides at our own peril...
Neonicotinoids pose broader risks to biodiversity and food webs than previously recognized. Serious efforts must be made to decrease the scale of their use.Opinion: Neonicotinoids pose undocumented threats to food webs
One of the main lessons that emerged from Silent Spring (1) is that we overuse pesticides at our own peril because human and natural environments are unquestionably linked. It is time to revisit these lessons given current use patterns of neonicotinoid insecticides. Neonicotinoids pose broader risks to biodiversity and food webs than previously recognized. Serious efforts must be made to decrease the scale of their use. Image credit: Shutterstock/lantapix. Since their introduction in the early 1990s, neonicotinoids have become the most widely used insecticides in the world. Their toxicity allows less active ingredients to be used and, compared with older classes of insecticides, they appear to have relatively low toxicity to vertebrates, particularly mammals (2). Neonicotinoids have been repeatedly called “perfect” for use in crop protection (2). Yet recent research calls this perfection into doubt as neonicotinoids have become widespread environmental contaminants causing unexpected nontarget effects. In particular, researchers have found that neonicotinoids can move from treated plants to pollinators and from plants to pests to natural enemies. Worse, transmission through simple food chains portends widespread, undocumented transmission into entire food webs. We believe that neonicotinoids pose broader risks to biodiversity and food webs than previously recognized. Although further research is needed to document the ecosystem-wide transmission and consequences of neonicotinoids to establish their true costs and benefits, serious efforts must be made to decrease the scale of their use. In 2014, the neonicotinoid market exceeded $3 billion and accounted for about 25% of the global pesticide market (3). Neonicotinoids are popular in part because they are very good at what they do. In fact, they are among the most toxic insecticides ever developed. The active ingredient imidacloprid, for example, is 10,000 times more potent to insects than nicotine, the biological inspiration for neonicotinoids and a very toxic compound … [↵][1]1To whom correspondence may be addressed.

Vibration overcomes gravity on a levitating fluid
Strange floating
Volumes of fluid have previously been made to float above air by vibrating the air–fluid system vertically. It now emerges that an ‘antigravity’ effect enables objects to float upside down on the air–fluid interface.

The study, published in the New England Journal of Medicine on Tuesday, looked at blood samples collected from over 30,000 people in Iceland, a bit under 10% percent of the small Nordic country’s total population. These included more than 4,000 people who had either tested positive for the novel coronavirus, SARS-CoV-2, or were suspected to have been exposed to someone with the virus. The samples were tested for several different types of antibodies tailored specifically to the virus.#science #medicine #health #Covid-19 #CoronaVirus #pandemic

Étienne Klein : Oui, et c’est ce qui m’a incité à publier ce livre. J’avais été agacé par ces gens qui disaient « je ne suis pas médecin, mais je pense que… ». On voyait des personnes affirmer leur incompétence, ce qui est honnête de leur part, mais, une fois cette incompétence assumée, elles donnaient des leçons. Et il y a eu ce fameux sondage du 5 avril selon lequel 80 % des personnes interrogées avaient un avis sur le traitement contre le Covid. À ma connaissance, c’est la première fois qu’on demande aux gens de décider si un médicament est bon ou mauvais, indépendamment des études qui ont été faites !Étienne Klein, philosophe des sciences : « Si un chercheur honnête dit "je ne sais pas" à la télé, on ne va pas le réinviter » - Charlie Hebdo

Thousands of coronavirus-deniers have gathered in London’s Trafalgar Square to protest against lockdowns and vaccination programmes.Just like Berlin, London had its own Covid-19 suicide party in Trafalgar Square today. Banners were waved claiming that black is white, madness is sanity, and Covid-19 is fake. With such a large number of people, not only was the 'protest' an illegal meeting, it also significantly raises the chances of there being far fewer such 'protesters' in future.
The ‘Unite for Freedom’ rally started at noon and called for an ‘end to Government lies’ and the ‘restoration of all freedoms.’
Pictures from the demonstration showed a sizeable crowd gathered in the square, holding signs warning that coronavirus is a ‘scam’ and a ‘hoax.’
