Available without a prescription and reimbursed at 100% by the Social Security, they are very popular with the population. But the strategy is extremely expensive.
By Marie-Cecile Renault
While the accounts of Social Security were to become surplus again, they will plunge back into the red this year, with an abysmal deficit of more than 50 billion euros, a record. The health crisis has brought down contributions entering the funds, while expenses soared on the side of Medicare: it is necessary to finance care, overtime for carers, equipment (masks, gowns, respirators, etc. drugs, etc.) To which must now be added the millions of screening tests.
And the bill for Social Security promises to be steep, since it is “open bar”: anyone can do an RT-PCR virological test, without a prescription and 100% reimbursed by Social Security. “Tourists, foreign seasonal workers can get tested, people who want to fly even take the exam in several labs to be sure to get the results on time.», Indicates François Blanchecotte, president of the National Union of Biologists. And this, even

An international team of researchers has discovered what may be the first survivor planet in the universe. The Jupiter-sized celestial body with the name WD 1856 b orbits its white dwarf, a star corpse, in a very close orbit – and thus would have miraculously survived the violent death of its mother star.

WD 1856 b could the first discovered “survivor” planet our universe. It is called the “survivor” planet by its discoverers: He has the death of his mother star – in this case a white dwarf named WD 1856 + 534 – survived. The results were published in the magazine “Nature”.
One White dwarf emerges, when a normal star his Has run out of fuel. It then inflates extremely and its gas envelope devours all planets in the near orbit. Finally, it sheds its shell, losing around 80 percent of its mass and finally ending up as a starry corpse.
WD 1856 b puzzles researchers: How did planet explosion survive?
This process makes WD 1856 b so special and puzzles researchersAs Andrew Vanderburg, assistant professor at the University of Wisconsin-Madison and co-author of the study, explains: “The process of birth of a white dwarf destroys all surrounding planets and everything that comes too close to the star’s corpse is actually torn apart by immense gravity Therefore the question arises: How did WD 1856 b get into its current orbit without suffering this fate? “
So far were about star corpses only fragments, comets and dust discs detected. One intact planet to find was therefore one surprise – but is but explainable. According to the scientists’ calculations, the celestial body must have emerged about 50 times further than from its current position. It is now orbiting its star in a 34-hour orbit. This corresponds to 60 times the orbital speed of Mercury around our sun. The researchers have several theories as to how this came about:
For one, there could be more big planets caused the orbit to spiral inward. Similar effects are known from other extrasolar solar systems.
That would also be possible Other stars fly by. Since the white dwarf WD 1856 + 534 is also part of a triple star system, corresponding constellations could have led to the migration of the planet.
Discovered the planet was through Data of Transiting Exoplanet Survey Satellite (TESS) NASA. The satellite examines the light from the stars and pays attention to fluctuations in brightness. These can be clues to an exoplanet if it moves in front of its star during a so-called transit.
So far have been no other worlds in the system around the star WD 1856 + 534 discovered. On the one hand, this can be due to the fact that the star is very faint, and on the other hand, it would also be possible that the plane in which other planets orbit the star is tilted so that their orbit does not cross the line of sight from Earth. It is also possible that there are simply no other planets.
Further investigations of the TESS data should provide new insights.

THE CHEKING PROCESS – The Marseille professor assured the senators that 4.6 billion people live in a country where this treatment is recommended against Covid. Really ?
THE QUESTION. As he had already done in June before the parliamentary committee on the management of the health crisis, Professor Didier Raoult again defended the interest of hydroxychloroquine against Covid-19 during his hearing in the Senate on Tuesday , even though the vast majority of doctors today agree that the molecule is not effective against the disease.
In response to senator and doctor Bernard Jomier, who gave a long list of countries now advising against the use of this treatment against Covid – a list that the Marseille researcher rejected – he thus argued that “4.6 billion people live in countries where hydroxychloroquine is recommended“. Before launching shortly after: “publications on the use of hydroxychloroquine show that it reduces mortality between 30 and 50%; they are accumulating, it keeps coming out, it comes out every day, you will see!»What is it?

After more than two years of reflection and studies, air quality experts in France have finally adopted a new index. It will come into force on January 1, 2021. It will integrate a family of additional fine particles, PM2.5 (which are 2.5 microns in diameter) and which are already measured by the 18 Air Quality Agencies in France.
In addition, the main alert thresholds for qualifying the air of poor quality will be lowered. They will concern PM10 (10 microns in diameter), ozone, nitrogen dioxide and sulfur dioxide, to align the French levels, which date back to the 1996 air law, with the thresholds Europeans. The six levels selected will be in line with those taken into account by the European Environment Agency (good, average, degraded, bad, very bad and extremely bad) which are already accessible online (airindex.eea.europa.eu ) for Europe.
The level announced daily for the current day and the next will correspond to the worst index of one of the five pollutants measured. It will be a “New communication tool for the general public, but which will not be binding”, explains Marine Tondelier, general delegate of Atmo-France, which federates the air quality agencies.
Sharp increase in the number of poor quality days
It will therefore not be possible to say that the air is degrading, compared to what is currently measured, since the scales are modified. However, the number of days with poor quality is expected to increase with the new index. For example, according to estimates made by Atmo-France in conjunction with the Ministry of Ecological and Inclusive Transition, the number of days of poor air quality will drop from 6 (with the current index) to 109 (with that of 2021 ) in Grenoble, from 14 to 108 in Lyon, from 10 to 83 in Paris and from 13 to 109 in Strasbourg.
Moreover, taking PM2.5 into account makes it possible to indicate a family of very fine particles which sink very deeply into the lungs. They, along with PM1 and those of smaller sizes, cause the most premature deaths in Europe. However, over twenty years, the concentration of PM2.5 has decreased in France and in Europe.
Decrease in PM2.5
“The annual average of PM2.5 fell by 46% between 2009 and 2019 on average in France. 5% of the territory’s surface remains exposed in 2019 to values above the threshold of the World Health Organization (10 µg / m3), or 28% of the population ”, notes Ineris (National Institute for the Industrial Environment and Risks) in a study on air quality in France.
Finally, the measurements on ultrafine particles are currently being assessed by the Central Air Quality Monitoring Laboratory, in conjunction with the Ministry of Ecological Transition and associations. For PM1s, the European Union does not yet take them into account in its index.
Venus returns to ignite the curiosity of researchers, space agencies and individuals, after the discovery in its atmosphere of phosphine gas, considered as a possible indicator of the presence of life. After the announcement made by the Royal Astronomical Society, NASA chief Jim Bridenstine himself wrote on Twitter that “it’s time to prioritize Venus”. And if in about thirty days the Bepi Colombo probe of the European Space Agency (ESA) will ‘touch’ the planet in its long run towards Mercury, a mission entirely dedicated to the atmosphere of Venus is scheduled for 2023, organized by the company US private Rocket Lab.
Currently there is only one probe in orbit around the planet, the Japanese Akatsuki: this is the second launched for a specific mission to Venus in the last thirty years. First there was the European mission Venus Express, which remained in orbit between 2006 and 2014. In both cases the main objective was the study of the atmosphere. Of the surface of Venus, on the other hand, there is a topographical study carried out in the 1990s by the Magellan probe of NASA, with an obsolete resolution. The last landing, on the other hand, dates back to the 1980s.
Things could change in the near future, in light of the different robotic missions that have recently been proposed to space agencies in the United States, Europe, Russia and India. Their approval, however, is not obvious, or at least it has not been so far: NASA, for example, has rejected several projects for Venus in past selections, favoring the exploration of asteroids and other planets, primarily Mars. These hesitations could favor private individuals in the race, such as Peter Beck’s Rocket Lab, which just a few days ago during a press conference said that the exploration of Venus represents “the definitive treasure hunt: in an area of about 50 kilometers l ‘Venusian atmosphere is relatively temperate and, at least in theory, could host life, although perhaps not as we understand it today “.
As the epidemic continues to recover, new restrictive measures have been taken by two large metropolises, Bordeaux and Marseilles. At the national level, the government is focusing on improving the efficiency of screening system weighed down by the congestion of laboratories. The urgency is great, as the clusters multiply in theHigher Education. However, everything must be done to avoid re-containment, in particular Ehpad, already severely tested. In Israel, it’s already decided. The country is reconfigured for three weeks.
Camille Lestienne, journalist at Figaro.
1. Local rather than national restrictions
Marseille and Bordeaux on the alert. Against all expectations, the government last Friday did not announce any new restriction measures. Jean Castex preferred to appeal to the responsibility of the French and to respect barrier gestures. “The state of mind is not to constraint, to prohibition, the objective is on the other hand to provoke an electroshock among the French», Commented the entourage of the Prime Minister. It is up to local authorities to make unpopular decisions. Marseille and Bordeaux, on alert, announced on Monday several provisions: early closing of bars in the evening, sale of alcohol prohibited after 8 p.m., canceled events, gauge for public events lowered to 1000 spectators, limitation of visits to nursing homes, etc. The situation of hospitals in the two metropolises is worrying. “We currently have 25 patients with Covid in intensive care, when there were none in early August», Indicates the management of the Bordeaux University Hospital. Faced with this rise in the epidemic, hospital services could be overcrowded again in a few weeks, further analyzes the Science department of Figaro. With 9,784 new cases detected in the past 24 hours, the epidemic is indeed continuing its recovery. The number of patients entering intensive care has increased further, with 508 new patients hospitalized in the last 7 days, 29 more than the day before.
Improved testing is still eagerly awaited. This afternoon at 5 p.m., the Minister of Health Olivier Véran will resume his weekly updates on the government’s strategy in the face of Covid-19. On the menu in particular, the tests whose implementation is so much maligned and whose failures, like those of the StopCovid application, angered the Head of State. “A million tests a week is all well and good, but if the results arrive too late, it is useless”, Emmanuel Macron would have lost his temper. Massive screening seems to find its limits in the embolization of the system. A pace difficult to keep up and denounced by the employees of the 20 Biofusion laboratories in Tarn-et-Garonne, Haute-Garonne and Lot. They went on strike to denounce the insufficient amount, 250 euros, of the “Covid bonus” granted to them. As for saliva tests, simpler and less unpleasant, they should be implemented in early October.
We don’t decide anything, it’s the politician who decides.
Jean-François Delfraissy, Chairman of the Scientific Council
Raoult, Delfraissy in the Senate. Didier Raoult got carried away in front of the senators. Heard before the commission of inquiry, the Marseille professor denied having ever defrauded. Heard before him, Professor Delfraissy, President of the Scientific Council recalled in the preamble that the Council was in no way a new “Medical power”. “We don’t decide anything, it’s the politician who decides”, he hammered, way of responding to the accusations made in particular by Yannick Jadot. The EELV MEP had declared the day before that the Scientific Council “Through the voice of its president[…], morning, noon and night, especially trying to scare the French “. In the hearts of the French too, the balance tilts in favor of Professor Raoult. According to a survey, one in two French people (52%) today looks positively on Professor Didier Raoult and 49% of them say they trust the Marseille doctor in the face of the 46% who say they trust in the speeches of the Scientific Council.
2. Clusters in universities, re-containment in nursing homes
The fear of confinement in nursing homes. Reduced visits to some cities, banned in Nice in municipal establishments, nursing homes face a new dilemma. While clusters appear as in Sévérac-d’Aveyron where 5 residents died, retirement homes fear a new confinement so deleterious for the elderly. “My hundred-year-old grandmother, who lives in a private nursing home, has been re-defined since mid-August. She hasn’t been out since February. Since the start of the epidemic, there have only been six weeks where visits have been allowed, confides to Figaro, Hélène, a Parisian executive. I’m afraid she’ll die alone, abandoned, with no one by her side.The staff of nursing homes is not spared by the crisis either. Anxiety, fear, professional exhaustion and even depression push them to consult via the psychological help devices deployed in force.
Clusters in universities and schools. At the other end of the generational spectrum, students are tackling a start to school year shaken by the Covid. At the Faculty of Medicine of Montpellier, a third of the students in a promotion have tested positive. In Toulouse, 127 students from an engineering school. All contaminated during outdoor evenings. With the proliferation of clusters, some establishments are falling into “all distancing”. In primary and secondary education, 81 schools and just over 2,100 classes have been closed, said Jean-Michel Blanquer. The management of the health crisis turns into a headache for school directors, doctors or parents who are asked for medical certificates or certificates on honor. “The minister may minimize the situation, the fact remains that many students follow a dotted education, says Guislaine David, at Snuipp, the first primary school union. We close a class for a week and a few days later, it’s the one next door. It is endless.»
3. Draconian measures in Israel and Cuba
Israel is reconfiguring itself. With 4,000 cases of contamination per day, the Hebrew state has become, according to the population, one of the countries in the world most affected by the epidemic. The death toll rose from 322 dead in early July to 1108 on Sunday. These figures are worrying enough for the government to decide on a three-week re-containment from next Friday. In the midst of religious holidays, the decision divides and offends the ultra-Orthodox. “There is no alternative to confinement, warned Minister of Health Yuli Edelstein. The coronavirus is not about populism, it is about life and death. I invite those who claim the contrary to visit the care units.»
Cubans are also in despair. Faced with the rebound of contaminations, Havana was placed under curfew from 7 p.m. to 5 a.m. “The measures are draconian, relates the correspondent of Figaro. Public transport is at a standstill. The shops lower their blinds at 4 p.m. Non-essential businesses are closed. Children must stay at home. Havanese are now prohibited from buying food anywhere other than their arrondissement. When they go there, it’s fear in the stomach. ” A crisis managed with an iron fist, but which, since the spring, has recorded tangible health successes.
4. Reflexes to keep
A few simple actions can limit the spread of the virus. Here they are :
Wash your hands every hour
Cough or sneeze into the crease of your elbow
Use disposable tissues
Avoid kissing or shaking hands
Wear a mask in public spaces when respect for physical distances is not guaranteed.
Covid-19 is transmitted by droplets (respiratory secretions), by close contact with an infected person, especially when the latter coughs or sneezes. But it could also be transmitted through the air. The virus also remains viable for a few hours on different surfaces.
The disease manifests itself in several symptoms. In 9 out of 10 cases, this results in a fever below 39 ° C. According to the World Health Organization, this fever is most often accompanied by fatigue, signs of shortness of breath and a dry cough. Often a loss of smell and taste.
5. What to do in case of symptoms?
The most important thing is to get tested. According to the recommendations of the Ministry of Health, you should, in case of symptoms, stay at home and contact your doctor who will order a test. While waiting for the result, you must isolate yourself, wear a mask and prepare a list of people you could have infected.
If the test is positive, the Primary Health Insurance Fund will contact people likely to be infected. You must then remain isolated for at least 8 days, taking care not to infect your loved ones. Watch your health. In case of fever, take paracetamol. Plan a follow-up remote consultation with your doctor if necessary. If you feel that you are having difficulty breathing, call 15.
If the test is negative, contact your doctor and follow his instructions.
Donald Trump has placed a new climate skeptic in an administration that funds a lot of environmental research. David Legates, a professor of climatology at the University of Delaware who does not attribute the warming of the Earth to the combustion of fossil fuels, has become an official of NOAA, the administration in charge of the ocean and the atmosphere. If he does not become the director general either, the revelation of this appointment last weekend by the public radio station NPR has provoked a new outcry against the environmental policies of the President of the United States.
The appointment of David Legates comes, in the midst of the campaign for the election of the President of the United States, at a time when California and Oregon are suffering the most important forest fires since 1987. And Donald Trump assures us that these disasters have not nothing to do with climate change …
A “Appointment that undermines the scientific integrity of NOAA”, the American Geophysical Union
The American Geophysical Union (AGU), a powerful learned society that chaperones, among other things, climatology, deplored an appointment whose “consequences will be felt around the world». Car «with climate change causing wildfires in the western United States and devastating hurricanes in the Atlantic, our nation – and the world – cannot afford for our federal government to undermine the important work of climate scientists. The Legates appointment not only threatens our ability to fight the climate crisis and protect our planet for future generations, it undermines the scientific integrity of NOAALaments the AGU. Scientists are thus calling for therevocation» de David Legates.
In the meantime, the scientist becomes the assistant of Neil Jacobs, who was notably in charge of airborne measurements at the World Meteorological Organization, and who oversees strategic research directions and annual investments of over 5.5 billion dollars.
Links with the oil industry
David Legates is linked to the interests of the oil lobby in the United States. In 2011, he had had to give up his role as chief climatologist for the State of Delaware, under pressure from the Democratic governor, because he had doubted the impact of fossil fuels, in particular in the rise in sea levels, Washington Post reports. Additionally, the scientist is linked to the Heartland Institute, a think tank funded by the oil industry. The “think tank” vigorously attacked the NPR article. The latter calls into question the skills of its author, qualified as“Ignorant journalist, funded by taxpayers, who ignores the scientific method” and who confuses “Science and dogma”.
The position to which David Legates has been appointed does not require the approval of the United States Senate, as is the case with some key positions in several administrations.
In 2017, the senators had for example retested the appointment of Andrew Wheeler, at the head of the EPA (US Agency for Environmental Protection). But his appointment was finally accepted a year later thanks to the support of senators from the Democratic Party, as deputy director and then director general in 2019. The latter, “lobbyistFor the coal industry, he and his predecessor Scott Pruitt had helped unravel the Obama administration’s air quality law.
THE CHEKING PROCESS – Last April, the influx of patients in serious condition had put hospitals in difficulty. With the resumption of the epidemic, could we experience a similar situation?
THE QUESTION. After a summer truce, the virus is back: the number of cases is increasing in most French metropolitan areas, as are hospitalizations. In the last seven days, 2,561 people have been admitted to hospital, including 448 in intensive care, against respectively 1,704 admissions (including 288 in intensive care) the week of August 31, according to Public Health France.
This brings the total to just over 5,479 patients hospitalized in medical service because of Covid-19, to which are added 705 patients in intensive care or intensive care. Faced with this rise in the epidemic, are hospital services at risk of being congested again in a few weeks?
CHECKS. As in the first phase of the epidemic, it all depends on the “height»Of the wave, ie the number of patients in serious condition simultaneously requiring hospitalization in intensive care. Last April, this number had exceeded the capacity of some establishments in the zones

DECRYPTION – This type of wave, constantly present in the world and in the human body, returns to the table as a report discusses the effects of 5G on health.
The debate on 5G has revived the controversies over electromagnetic waves, and their supposed dangers. But what exactly are we talking about? Throw a pebble in the water, it deforms around the point of fall; you created a wave. Take an electron, apply an energy to it; by vibrating it will deform its electric and magnetic fields. Congratulations, you have created an electromagnetic wave!
Do not boast too much: like any object whose temperature is above absolute zero, your body constantly produces it. Visible light is also an electromagnetic wave. In fact, the world is constantly bathed in a cloud of electromagnetic waves … Huge advantage of these waves: they propagate at the speed of light (300,000 km / s), can travel in a vacuum and cross all kinds of obstacles .
Their two important characteristics are their frequency (measured in Hertz, Hz) and their amplitude. Grab the end of a rope, then make a wide gesture of high

Stopping the traffic reduced the concentration of the smallest soot by 40%.
The confinement, from March 17 to May 11, 2020, had an indirect positive impact in the capital. A fall in air pollution would have helped to reduce the number of premature deaths.
“We were able to count particles larger than 0.2 micrometers in diameter up to an altitude of 300 meters, in the air column above Parc André Citroën in Paris using the Generali balloon, explains Jean-Baptiste Renard, researcher at the CNRS environmental and space physics and chemistry laboratory in Orléans. The day after confinement, there was a marked drop in the total number of particles measured in the air. We then noted a 40% drop in the number of these very fine particles, due to a sudden stop in road traffic ”.
AirParif, the association that measures air quality in Île-de-France, has a slightly different assessment. “During confinement, we measured a 30% decrease in ultrafine particles (PM 0.1), and a 7% decrease in fine particles
