Google's "tech giant" is facing one of the biggest antitrust lawsuits in two decades, with the US Department of Justice suing the flagship company for "anti-competitive behavior".

The US Department of Justice has filed a lawsuit against Google, accusing it of using anti-competitive methods to maintain its position and monopolize the Internet search engine market and related advertising activities.

In fact, Google acquires more than 92 percent of the global search engine market, and in order to reach this position, it has made exclusive deals to control the market and block the way for any company trying to compete in the same field.

In the smartphone market, Google acquires 95 percent of the search engine market by placing its main search engine, whether on its operating systems, Android, or iPhone operating systems, as Google pays up to $ 8 billion annually to Apple for this Franchise.

As is the case for computers, where Google is the main engine on most different browsers, with a share of 87 percent globally.

From the US government's point of view, allowing Google to continue its anti-competitive paths would lose the next wave of innovators, and Americans may never benefit from the emergence of a similar company to Google in the future.

As for the company itself, the government’s move is deeply flawed, and would actually harm consumers, because it would artificially support low-quality search options and raise the prices of phones.

Overall, this issue may lead to the division of the company, by separating search engines from advertising activities, and it may open the door to enacting legislation that would reduce the dominance of the giants of US technology companies in the digital economy, including Facebook, Apple and Amazon.

Arsenal makes a "tough decision" on Ozil


In a move that would enhance the possibility of his departure, Arsenal excluded their German playmaker Mesut Ozil from his squad that competes in the English Premier League.

The 32-year-old is the highest-paid player in the history of "The Gunners", estimated at 350 thousand pounds (450 thousand US dollars) per week, but he was also excluded from the squad that will compete in the European Football League, "Europa League," according to France Press ".

The German star has not played a single minute in the Spanish coach Mikel Arteta's squad since March 7.

Ozil will be able to participate only with the U-23 squad, until at least 2021.

The Turkish-born player has reached his last season with Arsenal, and he will likely not be able to carry his colors officially anymore.

Ozil had insisted last August that he was the only person who would decide when he would leave, despite his removal from the squad.

Last September, the Arsenal coach considered it difficult for Ozil to find his way into the starting line-up in his team, which he described as "developing".

It is reported that Ozil, whose contract expires in June, did not play at the end of last season, and was out of the squad for Arsenal's first three games in the new season.

Barcelona renews contracts for "four stars"


Barcelona announced the renewal of contracts for four of its players, namely Gerard Pique, Dutchman Frankie de Jong, German goalkeeper Marc-Andre ter Stegen and French defender Clement Langley, adding that they had reached an agreement on a "temporary salary adjustment".

"The agreements were reached after weeks of negotiations and include a temporary salary adjustment due to the current conditions caused by the Covid-19 crisis," the Catalan club said in a statement.

Pique renewed his contract until 2024 on the condition that the defender play a certain number of matches in the 2021-2022 season, AFP reported.

In the event that the Spanish international stayed at the "Camp Nou" stadium until the end of the contract, which includes a penalty clause worth 500 million euros, he will be 37 years old.

The renewal of Ter Stegen's contract until 2025 will bring reassurance to Barcelona, ​​especially after the distinguished levels he has provided with the team in the past two seasons, as the value of the penalty clause also reached 500 million euros.

While De Young and Langley renewed their contracts until 2026, where the value of the penalty clause amounts to 400 million euros for the first and 300 for the second.

A team of German scientists managed to record the shortest time interval ever, which helped them measure the time it takes for a molecule of light to pass through only one molecule of hydrogen.

According to CNBC, this very short interval took 247 "zeptoseconds", and what is known in physics is that "zeptoseconds" are a fraction of many milliseconds.

According to physics, a “zepto-second” is equal to one trillion billionth of a second, equivalent to a number followed by 20 zeros.

Experts believe that this discovery culminates in a global effort to measure infinitely short time intervals in physics, which have not been recorded before.

Some may wonder about the benefit of these measurements, and here experts say that they benefit from the results in order to more accurately measure the changes of the atom through what is known as the "photoelectric" effect.

The German genius, Albert Einstein, presented his famous theory on the effect of "photoelectricity" in 1905, providing a description of the phenomenon that occurs when electrons are emitted from an atom, as a result of its exposure to light.

In 1999, the Egyptian scientist, Ahmed Zewail, used ultrafine "laser" pulses to observe how the particles undergo a change in shape.

After that, Zewail, who won the Nobel Prize in Chemistry, was able to measure slight changes in a time unit known as "femtosecond", which is a million billionth of a second.

The most recent achievement is currently by researchers from the Goethe University in Frankfurt, the Max Planck Foundation in Berlin and the DESY Research Center in Hamburg.

And these scientists were able to measure a shorter interval in time, and the results of the study were published in the scientific journal "Science", on the sixteenth of October.

The researchers shed rays from an accelerator device on a molecule of hydrogen, and the latter includes two protons as well as two electrons.

These protons and electrons are very small particles that move in the core of the atom, which have an electrical charge.

The scientists explained that they used only one particle of light, that is, one photon, to stimulate the electrons, and in a later stage, they used rapid reactions by an infrared "laser" to monitor what happened next.

When a photon was shone on the hydrogen molecule, an electron was released first, and a second later, waves occurred that allowed the scientists to complete the measurement.

Researcher Steve Grundman, an academic who completed the most important part of the study, said, "Since we knew the spatial orientation of the hydrogen molecule, we relied on the interference of the two electron waves to more accurately record the moment of arrival of the photon, as well as monitor the moment of arrival at the second hydrogen atom."

The scientists reported that this whole process required 247 "zeptoseconds" of the photon to pass through the hydrogen molecule, but things change according to the time separating the atoms in the hydrogen molecule when the photon is shed.

The "Burger King" restaurant chain in Japan is set to launch a secretive fast food known as "Fake Burger", starting October 23.

Fox News stated that the "fake burger" will be available for only two weeks in some of the "Burgerking" branches in Japan.

According to a poster, which the restaurant posted on its official Twitter account, the burgers appear to be golden or yellow in color. Therefore, it is possible that a "bergra" is not real at all.

The picture was attached to a tweet, in which it said: "We cannot tell you the details of the taste and contents yet ... But once you eat it, you will definitely be addicted to its delicious taste," according to the American Fox News website.

It is believed that the cost of a secret "fake burger" will be cheaper than a "Whopper" meal.

Two months ago, Burger King faced strong criticism because one of the outlets of the American fast food giant in China used expired ingredients.

A fast, reliable and cheap test to detect infection with the emerging coronavirus, consisting of a thin strip made of interactive paper, will soon be available in India, after it was developed by scientists in this country to help curb the spread of the pandemic.

The examination was named "Veloda", after the hugely popular investigative figure composed by the famous Indian filmmaker Satyajit Rai (1921-1992).

This Covid-19 test uses the "molecular scissors" technique known as "CRISPR Cas9", developed by French geneticists Emmanuel Charpantier and American Jennifer Doudna, and the two scientists were awarded this year with the Nobel Prize for Chemistry for their work in this field.

For this examination, samples are taken from the nose, which is very similar to the pregnancy tests that are conducted at home, with a paper strip that shows two colored lines in case the result is positive, knowing that this examination provides the result within one hour.

"This examination does not require any advanced equipment or highly qualified personnel," said one of the developers of the test, Sofik Mighty, from the CSIR Institute of Genomics and Integrative Biology of the Council for Scientific and Industrial Research in New Delhi.

"Many remote areas of India lack sophisticated laboratories," Maiti said, adding that the test "will be distributed more easily and will reach a greater number of people," according to "AFP".

India has recorded more than 7.5 million injuries, and is the second most affected country in the world after the United States.

And the new Corona virus infection has spread from cities with a large population such as Bombay, to rural areas where the availability of health services is limited.

Scientists running this test hope that this rapid test will allow the virus to be detected in the poorest areas of the country.

India is currently using RT-PCR virus detection tests, which require sophisticated laboratory equipment as well as antigen tests, are much faster and do not require in vitro analysis, but are much less accurate.

The "BCR" tests reveal the genetic fingerprints of the emerging corona virus, while the antigen test detects the presence of proteins specific to this virus.

The "Veloda" examination is considered a major advance in India, as are other tests developed in various countries, because its result is reliable, such as the "PCR" examination, with its availability much more easily, according to what the administrators confirm.

It received the green light from the Indian authorities controlling the sector, and Indian Health Minister Harsh Vardan confirmed last week that it could be distributed across the country by the large "Tata" group in the coming weeks.

And if that happens, India will be one of the first countries to make widespread use of such tests.

There was no information about its price, but local media indicated that it cost approximately 500 rupees (5.8 euros). On the other hand, a PCR test may cost 2,400 rupees in a private laboratory in New Delhi.

The French anti-terrorism prosecutor, Jean-Francois Ricard, said, Wednesday, that the authorities have arrested 16 people, including 5 minors, in the file of the murder of the professor of history, who was massacred in Conflans-Saint-Honorine.

Ricard explained in a press conference that students in the middle school where the professor was teaching had directed the terrorist to the location of the victim in exchange for a sum of money.

He added, "Two students at the school provided information to the perpetrator of the attack about the identity of the teacher in exchange for an amount ranging between 300 and 350 euros."

He added, "Abdel-Hakim Safriwi was known to the security services and accused of inciting hatred."

The Public Prosecutor for Combating Terrorism in France announced Friday that it had opened an investigation following the beheading of a history professor at Conflans Saint-Honorine.

The Public Prosecution stated that the investigation into the events that took place around five in the afternoon near a school was opened on charges of committing a "crime related to a terrorist act" and a "terrorist criminal group."

Police officers in the criminal department in Conflans-Saint-Honorine, 50 km northwest of Paris, received a call to pursue a suspect wandering around an educational institution, according to the prosecution.

At the scene, the police found the victim, two hundred meters away, in the locality of Iranians, and tried to stop a man carrying a white weapon and threatening them, then they shot and killed him.

The place was cordoned off and the demining department personnel were brought in on suspicion of an explosive belt, and after the incident, Interior Minister Gerald Darmanan, who was in Morocco, decided to return immediately to Paris.

And the French police indicated that the man who was attacked was a history professor who recently showed cartoons of the Prophet Muhammad in a class on freedom of expression.

For his part, French President Emmanuel Macron said that a man slaughtered a history teacher who showed his students in preparatory school caricatures of the Prophet Muhammad. This attack was aimed at striking freedom of expression.

"The citizen was killed today because he was a teacher and because he was teaching the students freedom of expression. The whole country stands with the teachers. The terrorists will not divide France ... obscurantism will not win," Macron continued, saying, near the school where the teacher was killed.
