On October 27, the French city of Cannes witnessed a symbolic ceremony for the opening of the Cannes International Film Festival.
Festival organizers said that its short program includes only 4 films. A short film competition will also be held as part of the festival.
The president of the festival, Pierre Lescourt, told the French "Agence France Presse" that the festival organizing committee has taken all possible precautions to prevent the spread of the Corona virus. All festival participants were informed of the need to wear face masks and adhere to social distancing measures, and the committee asked the guests not to stay for a long time on the ladder of the Festivals Palace.
The festival president explained that the achievement of the shortened program is a symbol of respect for film artists. At the opening ceremony of the festival's short program, he showed the film "Victory", directed by Amanuel Korcol. In the following two days, "Real Mothers", directed by the Japanese, Naomi Kawase, and "The Beginning", directed by Georgian Dia Columbegashvili, who entered the program of the "San Sebastian" International Film Festival, will also be shown.
As for the remaining films selected by the festival jury, they were awarded the status of "Honorary Participant" at the "Cannes" Film Festival.
It is noteworthy that the "Cannes" International Film Festival 2020 was postponed from last May to this October due to the spread of the Corona virus epidemic in the world.
Experts warn that an asteroid called "God of Chaos" is gaining speed as it moves on its path toward Earth, and it could strike our planet within 48 years.
Astronomers at the University of Hawaii confirmed that the huge asteroid, named after "Apophis" (the god of chaos), accelerated in its path due to the irregular radiation, which acts as a small nudge.
Prior to the discovery, impact was said to be impossible, but the new findings indicate the asteroid has a chance to collide with Earth on April 12, 2068 - and that could be catastrophic.
Apophis is more than 1,000 feet wide, and will have an impact of 880 million tons equivalent to a three-nitrotoluene (TNT) explosion in one go.
The asteroid was discovered on June 19, 2004 by astronomers, at the Kit Beck National Observatory in Arizona.
Since then, the asteroid has been tracked as it orbits around the sun, in a cycle that completes it with less than a year on Earth.
The researchers monitored "Apophis" with the "Subaru" telescope earlier this year, and determined that its speed increased after the analysis, known as the "Yarkovsky" effect.
When the asteroid body is heated in sunlight, it radiates energy away as heat, which acts as small nudges for the cosmic body.
Dave Thulin, one of the astronomers, said: “The new observations that we obtained with the Subaru telescope were good enough to detect Yarkovsky’s acceleration to Apophis, and showed that the asteroid is drifting away from a purely gravitational orbit, approximately 170 meters per year, which is what It suffices to continue the 2068 impact scenario.
Apophis has also been awarded the title of the third highest threat on NASA's Tracking Risk Table, according to Gizmodo reports.
The table estimates that there is a 1 in 150,000 chance of an asteroid colliding with Earth within 48 years, but Thulen told Gizmodo that the odds are closer to 1 in 530,000 - this number explains the Yarkovsky effect.
The asteroid contains nickel and iron, and radar images indicate that it is elongated, making it appear like a peanut.
The researchers noted that more observations must be made in order to fully understand the breadth of the Yarkovsky effect, and how it affects the orbit of Apophis. They plan to "see if there is any chance of an impact before 2068."
When Apophis was first discovered, experts said there was a 2.7% chance of a collision with Earth in 2029, but data now show that it will pass safely within 1,974 miles of Earth.

A multidisciplinary team has 3D printed a replica of a human tongue, complete with artificial soft surfaces and tongue-like tissues.
Scientists led by the University of Leeds, in collaboration with the University of Edinburgh, have accurately simulated the surface of the human tongue which plays an important role in how food tastes, the way food is spoken and swallowed, and nutrient absorption, among other functions.
The scientists claim that the biomimetic tongue accurately simulates structure, flexibility, and "wettability".
A synthetic silicone skeleton could play a game-changing role in examining new oral technologies, while improving nutritional technologies, drugs and treatments for dry mouth.
The team, made up of food scientists and experts in soft matter physics, dentistry and mechanical engineering as well as computer science, focused on the anterior dorsal segment (roughly the middle of the visible tongue, past the tip but before the base).
This region is partly covered by some papillae (small gaps spread across the tongue), which contain the taste receptors, although not all of them act as taste receptors. The team took molds for tongue roofs from 15 adult participants.
Lead author, Dr Evrin Andablo Reyes, who described the work as a "unique architectural challenge", said: "Hundreds of small bud-like structures called papillae give the tongue a distinctive rough texture, which, along with the soft nature of the tissues, creates a complex landscape. From a mechanical perspective. "
These impressions were then visually scanned with a 3D technique to map the dimensions of the papillae on the surface, in addition to their density and average total roughness of the human tongue. And it turns out the texture is a lot like a random plot.
A new study found that more than 80% of the 200 patients with "Covid-19" hospitalized in Spain had low levels of vitamin D.
The study, which was published in the Journal of Endocrinology and Metabolism, found that the majority of patients being treated for "Covid-19" in a hospital in the northern city of Santander suffer from vitamin D deficiency.
And researchers at the University of Cantabria determined that only 82% of the 216 patients had insufficient levels - compared to 47% of the people in the control group who did not have the virus.
This vitamin, which promotes bone health and supports the functions of the immune system, is produced naturally by the body when exposed to sunlight, and it can also be obtained from eating foods such as fatty fish, egg yolks, mushrooms and cheese.
Patients with a deficiency of the sun vitamin in the study were more likely to have high blood pressure and heart disease, as well as spend longer in the hospital.
However, researchers found no link between vitamin D deficiency and disease severity, with no significantly higher rates of ICU admission, ventilator use, or death, among those with insufficient levels of the sunshine vitamin.
The study represents the latest research that tries to determine whether vitamin D deficiency contributes to the exacerbation of "Covid-19" cases.
In the study, vitamin D supplementation was also given from the admission point of 19 patients, who were assessed separately from the rest of the group.
However, the group that took the supplement had a "somewhat slight drawback" compared to those who did not - they had low oxygen levels, needed more medication to help treat inflammation, and found that they were more likely to be admitted to the care unit.
But the researchers said the results could be explained by six out of 19 people who took the nutritional supplement who had recently taken corticosteroids or immunosuppressants in the previous three months, which could affect the severity of their disease.
Dr. Jose L. said. Hernandez, the co-author, continues to recommend nutritional supplements for patients with vitamin deficiency.
He said in a statement: "Vitamin D treatment should be recommended for Covid-19 patients who suffer from low levels of vitamin D in the blood, because this approach may have beneficial effects on both the musculoskeletal system and the immune system."
But other experts have previously warned that more research is needed before prescribing the vitamin to ward off serious conditions.
Previously, Carolyn Gregg told the Times of India: "Although there is some evidence that vitamin D deficiency is associated with acute respiratory infection, there is currently insufficient evidence for vitamin D as a treatment for" Covid-19 ", Excessive intake of supplements should be avoided as it may be harmful.

A passenger plane "Tu-154" of the Russian airline "Alrosa", today, Wednesday, carried out its last flight in Russia, as it made a flight in Siberia between Yakutia and Novosibirsk.
The Russian airline said, in a statement: "The only remaining plane in the civil aviation fleet, Tu-154, carried out its last flight today (October 28, 2020)."
According to the company, the plane carried out a two-hour flight from Mirny in Yakutia, and the city is the diamond capital in Russia, to Tolmachevo Airport in Novosibirsk, where it transported 140 passengers.
The director of the airline "Alrosa" Andrei Golov commented on that, saying that the plane carried out the last flight with the expiration of the airworthiness certificate, and work will be made to replace it with a modern, more efficient and more economical one, and after turning off the Tu154, the plane will remain at Tolmachevo airport until a decision is made Regarding her future fate.
The "Tu-154" is a jetliner with three medium-range engines and is classified within the narrow body aircraft designed and manufactured in the mid-1960s by the "Tupolev" Aircraft Company, and began carrying out flights since February 1972.
The model has a range of about 5,000 kilometers and is able to take off from an unpaved runway, and it has been widely used in airports in the far Arctic.
During the past five decades, this model carried millions of passengers and thousands of tons of cargo.
At the time of its production in the 1960s, it became the backbone of the Soviet airline "Aeroflot" and all the airlines operating in the USSR, with more than 1,000 aircraft of this type manufactured.
The administrators of the "YouTube" application for phones and smart devices announced a new package of modifications and features that will be introduced to the application soon to make it easier to use.
Among the important features that the application will get is a feature that will allow video makers to divide video clips into parts and name each section separately, which will make it easier for users to see the clip that will suit them without having to view the entire video.
As for the other feature that will interest many users, it is related to the way the videos are displayed. Currently, the videos can be viewed on the full screen through the "YouTube" application by either clicking on the zoom in the image button or rotating the phone or mobile device, but with the introduction of the new feature the user will be able to swipe his finger on a window The video from the bottom to the top to show the image on the full screen, and slide the finger from the top to the bottom to return the image to its normal size.
The modifications in the application will include the Enable Subtitle button, which will move from the settings menu to the main screen, as well as the automatic video playback button.
In the "YouTube" application for phones, there are currently many features that are unknown to many users, such as the advantage of passing video time back and forth by quickly clicking on the top of the display screen on the left or right.
Josep Bartomeu, before his resignation from the presidency of Barcelona, stated that the club had agreed to a proposal to participate in the new European Football Super League in a move that would guarantee the material future of the team.
"I can announce some exceptional news ... on Monday, the board of directors approved the requirements to participate in the European Super League in the future, a project supported by the big clubs in Europe," Bartomeu said.
The agreement to join the European Super League needs to be ratified by the members of the Catalan club.
Media reports said last week that six billion dollars had been allocated to launch the new competition, with the participation of 18 clubs from the five major leagues, and with the support of the giants Liverpool and Manchester United.
It is noteworthy that Bartomeu and the rest of Barcelona's board of directors resigned on Tuesday, before a vote of no-confidence that was scheduled for next month.
