Professor Marc Lipsitch, professor of epidemiology at the Harvard TH Chan School of Public Health, said the scientists signed a letter published in the journal Science to call for the attention of the scientific community. “What we’re saying is that the available evidence doesn’t rule out a laboratory origin of COVID-19, nor does it rule out a natural origin. And there’s really no solid evidence either. It’s just that. There’s quite a bit of evidence lacking right now, and we’re calling for it to be addressed because it’s such an important question,” said Prof. Meanwhile, the Business Standard on May 29 said that since last year, Professor Angus Dalgleish (British) and Norwegian scientist Birger Sorensen have come to a conclusion about the possibility that “the SARS-CoV-2 virus originated from To confirm their position, the two scientists published a 22-page paper in the journal Biophysical Discovery, explaining that, in the course of their research Researching the vaccine, they discovered “special traces” that the virus was not of natural origin.The clue was a row of four amino acids, which generate a positive charge and bind to negative human cells. . “The law of nature is that you can’t have four positive amino acids in a row. The only way to have this is to make it yourself,” commented Professor Angus Dalgleish. The article by these two scientists also affirms: “We now have no doubt that the SARS-CoV-2 virus was purposefully manipulated, forcing us to reconsider the We think there are retro-engineered viruses. They changed the virus, then tried to figure it out in sequence years ago. We’ve seen leaks. We know it’s happening in the lab, and we know it’s happening. We also know from the reports we’ve found that the coronavirus is studied in Biosafety Level 2 or 3 laboratories.” Both scientists are respected experts: Prof Angus Dalgleish is a professor of oncology in London known for his groundbreaking work on HIV vaccines while Birger Sorensen is a virologist and president of Immunor Pharmaceuticals, which is developing a COVID-19 vaccine called Biovacc-19. On May 26, US President Joe Biden ordered the country’s intelligence community to unravel the conspiracy theory that the virus leaked from a Chinese laboratory and must provide an answer within 90 days. Doubts Apparently, the hypothesis that the SARS-CoV-2 virus could be the result of a scientific experiment has heated up the debate among scientists about the operation of the safest biological laboratories in the world today. . The Wuhan Institute of Virology, which is suspected of leaking the virus, is a virology research institute managed by the Chinese Academy of Sciences (CAS). Located in Jiangxia District, Wuhan, Hubei, Wuhan Institute of Virology has China’s first biosafety level 4 (BSL – 4) laboratory and has close relations with the National Laboratory. Galveston in the US, the Center International de Recherche en Infectiologie in France, and the National Microbiology Laboratory in Canada. Gregory Koblentz, director of Biodefense Graduate, revealed that BSL-4 is built to work safely and securely against the most dangerous bacteria and viruses that can cause serious illnesses for which there is no treatment or vaccine. : “There’s an HVAC filtration system, so viruses can’t escape through the exhaust. Any wastewater that leaves the facility is treated with chemicals or high temperatures to ensure that nothing remains alive. The researchers themselves are highly trained and wear protective clothing.” Statistics show that there are 59 BSL-4s around the world but there are no binding international standards for safe, confidential and responsible work with pathogens. The report, Mapping Maximum Biological Containment Labs Globally, shows that accidents can happen, sometimes in top-tier facilities, and more often in lower-level labs. For example, the human H1N1 virus – the same flu that caused the 1918 pandemic, was leaked in 1977 in the Soviet Union (former) and China. In 2001, a mentally disturbed employee at a US laboratory sent anthrax spores across the country, killing five people. Two Chinese researchers exposed to SARS in 2004 spread the disease to others, resulting in one death. In 2014, a handful of vials of smallpox were discovered during an office move by the US Food and Drug Administration. Lynn Klotz, a senior scientist at the Centers for Non-Proliferation and Control, has been sounding the alarm for years about the public safety threats posed by such facilities. “Human error accounts for more than 70% of errors in laboratories, adding that US researchers must rely on data from freedom of information requests to learn about incidents.” hey,” Lynn Klotz said. These incidents do not mean that COVID-19 has leaked from a laboratory and the fact that there is no scientific evidence to support the scenario yet, said molecular biologist Richard Ebright of Rutgers University. laboratory accident for this pandemic.

Accordingly, the application can only use up to 5 GB of RAM on the latest iPad. According to the developers, trying to use more than this amount of space causes the application to crash. Photo: The Verge “There was a big problem with the iPad Pro running the M1 chip. After testing the pressure tests on an iPad Pro M1 with 16 GB of RAM, it turned out that the application could only use 5 GB of RAM or less. If used more, the application will crash. This limit is only 0.5 GB more RAM than the old iPads that only had 6 GB of RAM,” the programmer shared. Photo: The Verge Thus, with single applications, as is the case with Artstudio Pro, users do not seem to benefit too much even though the new iPad Pro has an increased RAM capacity. However, overall, with the increased amount of RAM, you can still open more applications to run in the background at the same time because iPadOS itself is not limited to the amount of RAM used. Photo: The Verge The iPad has long been criticized that iPadOS doesn’t allow users to take advantage of the device’s full hardware potential. Apple will hold this year’s WWDC event on June 7. Here, iPadOS 15 will certainly be introduced as well. Bloomberg previously said that iPadOS 15 will bring a completely redesigned Home screen.

Shadows are just random things you see on the road made by objects, however, if you have a chance to visit Redwood City, California, you will be amazed to realize that the shadow does not match. with shadow objects. Living in California, USA, Damon Belanger is an artist known for his diverse artworks. His recent project impresses with shading drawings of very ordinary objects that give a new picture to the street. The series of paintings is quite cheerful and humorous, at first glance everyone thinks it is just an ordinary object, but when you look closely, you will see many differences. Anyone who happens to come across a piece of shading art will feel confused and have to look back a second time to spot the difference. Damon Belanger has filled the streets of downtown Redwood, California, USA with his interesting works of art. The whole city seems to turn into a wonderland attracting tourists. Artist Damon Belanger was inspired by simple things like bicycle racks, benches, trash cans, etc., inanimate objects that can appear on any street. Damon created these beautiful shading artworks and breathed new life into many lifeless streets. That’s when the artist transforms the mailbox into a cartoonish, smiling monster, the city map into a robot, the road markers into flowers… To begin the process of creating a unique piece, Damon selects the object he wants to shade and then sketches a character or painting using chalk. The artist cleverly chooses the angle to place the work so that it resembles the shadow as much as possible. Damon’s pictures are playful and humorous. After painting, Damon will paint over it with gray paint to make the picture last longer. Damon hopes that he can bring this project to larger cities across the United States to bring joy to everyone. Damon’s artworks are proof that a very creative artist can turn any public place into his ‘playground’.

He added that the Abel Prize (considered the Nobel Prize for Mathematics) in 2021 was awarded to a pioneer in the field Zero Knowledge Proof – Scientist László Lovász (Mathematical Institute Alfréd Rényi and University of Eötvös Loránd in Budapest, Hungary), and Avi Wigderson (Institute for Advanced Study in Princeton, USA). The puzzle is as follows: Isla works in an office with 100 employees. One day, she discovered that her favorite paperclip was stolen by someone else. She identifies the suspicious object. Annabel, her colleague, said she was also suspicious of a person. Isla wants to know if she and Annabel are suspicious of the same person, but the two don’t want the other to know who they are doubting, in case they suspect different subjects. Isla thinks over and over how she and Annabel can check if they suspect the same person without revealing the information they find suspicious to the other party. The question is whether Isla and Annabel can find a way to reconcile their thoughts without letting the other know who they are doubting? This method should ensure that, after comparison, Isla knows whether she and Annabel are suspicious of the same person. Second, they need to make sure the other person doesn’t know they are distrusting. This verification is part of the protocol Zero-knowledge . At first glance, Alex Bellos judged that this was a puzzle without a solution. For example, Isla cannot say “The person I suspect was late for work on Monday” because it revealed some information about the other person. He also came up with a third party two-man solution, Dan, a good friend they trust a lot. Then, Isla and Annabel numbered the office staff from 1 to 100. Next, they write the number to replace the name of the suspect on a piece of paper and give it to Dan. If Dan confirms the two numbers are the same, they suspect the same person and vice versa. However, this solution is not perfect as no one can guarantee Dan from disclosing his number to the other person. Everything depends on the level of trustworthiness of the third party. Therefore, it cannot guarantee the non-disclosure of information as the quiz requires. Nearly 200 people participated in discussing Alex Bellos’s riddle and proposing measures to verify that Isla and Annabel were suspicious of the same person. Then, the author Alex Bellos together gave 3 relatively suitable methods. Can you take any measures to ensure the request of the assignment or not, ie Isla and Annabel know if they are suspicious of the same person and do not disclose information about the suspect to the other person?

Somali Government soldiers patrol the streets of Mogadishu. (Photo: AFP / VNA) Security Council United Nations On April 23, (UN Security Council) passed a statement calling on factions in Somalia to end the violence and immediately return to dialogue in the spirit of considering this as an urgent matter and not setting conditions. This move shows that the Security Council is very concerned about the crisis situation in Somalia. In the release released, members Security Council All expressed concern about the continued political stalemate here and disagreement among leaders of this country over the issue of electoral patterns. Before that, on March 31st, after the emergency meeting, the Security Council was call upon Somali government please resolve the issues related to the electoral process. The legitimate administration of President Mohamed Abdullahi Mohamed, more commonly known as Farmajo, has caused controversy since February when his term ended with a new presidential election still not being conducted. By early April, a bill to extend his presidency by two years was introduced, bypassing the Senate after it was passed by the House of Representatives. Government opposition parties have voiced their opposition because it is an unconstitutional act to cling to power and the bill itself has been criticized by the international community. Somalia’s president and leaders of the five semi-autonomous states in the country last September reached an agreement that paved the way for presidential and parliamentary elections in late 2020 and early 2021 but This plan was broken by controversy surrounding the voting process and since then many rounds of negotiations have not been held to resolve this deadlock issue.

In the long march version of the small knife national endurance challenge that has been launched in recent months, with the newly developed extended range system, the long march version of the small knife faces various uncontrollable weather environments, such as strong winds, rains, steep slopes, muddy, etc., refreshing again and again Endurance record, at the same time, the Xiaodao electric car also completed its original goal of 300 miles on a single charge and an 80% increase in endurance. Through this challenge, the small knife electric car allows consumers to see its powerful strength of “big power, energy saving, and long run”.

In fact, before this challenge, the Xiaodao electric car has not only been recognized by China Aerospace, but also won the title of a major country brand enterprise and a strategic partner of China Quality Miles. It has been recognized by many authoritative organizations, and the Xiaodao electric car is a powerful brand. The strength is obvious. In addition, at this year’s Tianjin Exhibition, Xiaodao Electric Vehicles and China Aerospace once again launched in-depth cooperation. With the formal preparations of the “Aerospace Technology Electric Vehicle Application Laboratory”, the Xiaodao Electric Vehicles will be responsible for power enhancement, battery life extension, and battery insulation. Heavy and long way!

While the technology is constantly innovating, the Xiaodao electric car has always not forgotten the improvement of its own brand influence. Since 2021, the Xiaodao electric car has not only been a special sponsor of Ace to Ace 6'', and a designated brand ofSister Riding the Waves 2”, it has frequently appeared in major variety shows, and it has also signed the female volleyball leader Zhu Ting as a brand friend and international football superstar C. Luo Wei’s brand spokesperson, after many big moves, let the brand image of the small knife electric car, which is already a household name, more popular.

With the blessing of China’s aerospace science and technology, the small knife electric car will inevitably gain greater development, which will have an extremely far-reaching impact on both the industry and consumers.The road is long and long. We believe that in the future, the small knife electric car will continue to uphold the original intention and continue to advance, bringing us

According to Politico, Pentagon officials have passed intelligence on the suspected attacks to US lawmakers. However, a Defense Department spokesperson told the site that the agency was ignorant of direct energy attacks against US troops in Syria. US military soldiers in Syria. Photo: US Army Even so, according to two former US national security officials involved in investigative efforts, direct energy attacks on US soldiers abroad, suspected of being behind by Russia, are becoming. of such concern that the Pentagon’s Office of Special Operations and low-intensity conflicts began an investigation last year. It is unclear exactly how many US soldiers were injured or how badly they were injured. Direct energy attacks are used to describe directing certain energy sources to a specific target, such as using lasers or microwave energy, to cause total harm to human health. The investigation is part of a broader effort to investigate direct energy attacks on US government officials and agencies, Politico said. Previously, many US officials in Cuba, China and Russia mysteriously fell ill, with the main reasons allegedly being affected by microwave radiation sources.

Specifically, speaking before the meeting of the Defense Sub-Committee of the European Parliament in Brussels – Belgium, Andrii Taran noted that he could not rule out the possibility that Russian forces in Crimea could “take provocative actions. military promotion “in 2021.

Earlier, Mr Taran said “Russian provocations” could exacerbate conflicts in the Donbass region of eastern Ukraine bordering Russia. Taran revealed that Russia concentrates 110,000 troops on the Ukrainian border.

According to Reuters, any decision by Russia to move nuclear weapons to Crimea will be a bad development in East-West tensions. That gesture would increase tensions for a newly renewed arms control treaty between the US and Russia.

Concerning developments, in a statement from the Ukrainian army, the Ukrainian armed forces have been rehearsing to increase their ability to respond to a tank and infantry attack near the Crimea border on April 14. The drills come the day after US President Joe Biden phoned Russian President Vladimir Putin to discuss Russia’s military build-up near eastern Ukraine and in Crimea.

On the Russian side, on April 14, the Russian navy began exercises in the Black Sea with exercises to fire targets on the ground and in the air. This exercise is to test combat readiness, readiness to react to threats from NATO. As planned, the rehearsal would end after 2 weeks.

Northern flow 2: Germany receives a request for a building permit, President Biden falls into a ‘dilemma’. (Source: The Brussels Times)

The website Tagesspiegel.de recently published an article titled “A guaranteed gas supply even without the Northern Stream 2 project”.

Accordingly, the Northern Flow 2 gas pipeline project not only supplies gas to Germany and the European Union (EU) but also has strategic implications for the transition of energy, the environment and political geography.

Once again, this has become a central issue in the context of Russia increasing its military forces on the Ukrainian border and US Defense Secretary Lloyd Austin making his first visit to Germany.

The question is, is this piping system really necessary? What would the consequences be if the pipeline didn’t go into service?

The opinions are mixed

Experts have many different opinions. Some people, like Jens Hobohm from Prognos Institute for Economic Research (Germany), believe that Northern Flow 2 from an energy point of view is necessary and meaningful.

In contrast, expert Claudia Kemfert from the German Institute for Economic Research (DIW) argues that the answer is “definitely not”.

According to Kemfert, it is not necessary to have any additional infrastructure for the transportation of natural gas from Russia. In addition, the plan to increase natural gas consumption will conflict with the discussed and agreed climate protection goals.

This expert said that there would be no serious problems if the Northern Flow 2 could not be completed and put into operation. If gas from Russia cannot reach Germany through this pipeline system, Germany and Europe will find other energy solutions.

In this regard, new US President Joe Biden has stated that, like his predecessor, Donald Trump, he wants to prevent the completion of the project through the threat of punishing companies involved in the project. .

Still many EU partners believe that, with the assistance of the Northern Flow 2, Germany is acting against the common interests of Europe.

Chairman of the European People’s Party (EPP) group at the European Parliament Manfred Weber said that the Northern Flow 2 project “will definitely not be feasible” if Russian President Vladimir Putin lets the conflict in the region. East Ukraine escalated.

Will the gas supply be at risk then? To answer this question, the forecasts of the amount of gas that Germany and Europe will need in the coming years are central.

From the outset, critics accused the conglomerates that built the pipeline project “inflated” the data on German and European gas demand, making the project indispensable. and completely overwhelmed the opposition.

However, Jens Hobohm believes that this criticism holds true only in previous years, but in recent years, gas consumption in Germany and Europe has increased more than expected due to the need for natural gas. as a bridge for energy transitions.

When countries like Germany give up nuclear power, Poland reduces its dependence on coal, while solar and wind energy are still unable to meet demand, gas is the optimal solution.

According to a study by the Prognos Research Institute, in 2014, the EU consumed 400 billion cubic meters of gas; in 2015, the figure was 419 billion cubic meters and in 2019 it was 470 billion cubic meters.

Consumption figures for 2020 have not been specifically calculated, but according to expert Hobohm, this number is expected to decrease due to the impact of the epidemic of acute respiratory infections Covid-19.

In Germany alone, gas consumption will also increase from 77 billion cubic meters in 2015 to 89 billion cubic meters in 2019, while in 2020 this figure will decrease by about 2.5 percent.

Is that a compelling argument for the construction of the Northern Flow 2 project or would the existing pipes be enough to meet demand?

Is the project really necessary?

If we compare the gas consumption figures for 2019 to 2006, when the first Northern Flow system was planned to be constructed, it can be seen that the consumption volume has never been as high as it was before. Meanwhile, the project construction consortium insists that pipelines are needed as gas consumption will increase continuously. In fact, in 2006, Germany consumed 92 billion cubic meters of gas, while in the EU it was 511 billion cubic meters.

Hobohm adds that Europe’s gas imports from outside Europe depend on how much the continent can produce and to what extent can it meet its own demand?

Currently, the amount of gas produced internally has decreased, partly due to the Netherlands cutting production share faster than planned.

The key point now, experts say, is that the Northern Flow 2 project is still under construction. And Europe has no problems with gas supplies. Whether this project can go into operation or not and never work is an open question.

The later this pipeline is completed, the less necessary it is to be, as the role of natural gas will decline more and more.

Along with that, security policy risks are also very concerned.

First, it is due to the dependence of Europe and Germany on gas from a Russia.

Second, additional risks come from this project because the pipeline runs from Russia through the Baltic Sea and then directly to Germany, not through intermediate states such as Ukraine, Belarus and Poland.

Critics of the project raise two questionable issues.

FirstlyMr. Putin wants free hands to implement his policies with neighboring countries without being afraid to depend on them (when gas exports no longer have to pass through these countries).

Monday, the operation of the Northern Flow 2 system leads to a decrease in the amount of gas flowing through the existing pipes, thereby reducing Ukraine’s income from allowing gas from Russia to transit through its territory. .

The national budget of Kiev will be more than 2 billion euros. Then, the pressure on the EU to increase its aid to Ukraine will grow.
