The tragedy that happened on the night of April 14-15, 1912, is remembered to this day. On that day, after hitting an iceberg about 600 kilometers off the coast of Canada, the British transatlantic liner Titanic sank.

To date, the sinking of the Titanic remains the largest disaster in terms of the number of deaths at sea in peacetime. She, according to various sources, claimed the lives of 1495 to 1635 people.

For many years, experts have tried to figure out whether the iceberg was the reason why the liner sank. Watch the video to find out the answer to this question.

The media reported that anti-hypersonic military exercises were held in Russia. The Russian military learned to repel attacks with cruise and hypersonic missiles of a potential enemy. At the same time, the United States, for example, does not have such full-fledged complexes.

The exercises were held by anti-aircraft and anti-missile defense troops. The military checked the capabilities of the air defense forces to repel a simultaneous massive strike of a potential enemy from several directions. The emphasis was on combating promising hypersonic weapons and cruise missiles. The exercises were successful.

As the former deputy chief of the Air Force for the unified air defense system of the CIS countries, Lieutenant General of the Reserve Aytech Bizhev, noted, here it is necessary to “act in anticipation.” Potential foreign adversaries do not even have suitable weapons yet, but Russia is already learning how to repel them.

In Russia, the first domestic robotic dog was presented, which was created by engineers from the Research Institute of Mechanics of Moscow State University.

According to Moscow State University, the novelty received mechanics, drives, electronics and software developed by specialists from Moscow State University.

“There are not so many laboratories dealing with walking robotics in the world, and the appearance in Russia of prototypes of such devices creates the scientific and engineering potential of the Russian engineering school,” noted Anton Rogachev, leading engineer of the General Mechanics Laboratory of the Research Institute of Mechanics of Moscow State University. will give a serious impetus to the development of four-legged robots in our country. “

The 15-kilogram robot, which was developed over two years, received 12 drives with a total power of more than 3 kW. Some of the components are 3D printed from anisotropic composite materials and aluminum alloys. The development is currently being tested. The timing of the appearance of serial Russian-made robotic dogs is not named.

The activity of the human immune system changes depending on the time of day. According to the conclusion of scientists from the University of Geneva (UNIGE) in Switzerland and the Ludwig-Maximilian University (LMU) in Germany, when vaccinating against coronavirus, the time of day at which the injection is given may matter.

The studies were carried out on mice. Scientists monitored dendritic cells that actively recognize antigens – specific fragments of pathogens. Fragments usually allow vaccines to “train” the immune system to fight the virus and fight it without getting infected.

Experiments on mice have shown that dendritic cells move most actively at the end of the resting stage of the body, before resuming activity. For mice, this is the day, and for the human body – early morning before waking up.

Scientists are confident that in this way the time of day must be taken into account during vaccination and during anticancer immunotherapy, as this can increase the effectiveness of the procedures.

The General Director of Clinical Excellence Group, PhD in Medicine, immunologist Nikolai Kryuchkov said that correct timing is important to get the maximum effect from the re-vaccination against coronavirus.

He said this on the air of Sputnik radio.

“For now, the main criterion that it is time to revaccine against COVID-19 is the period from the disease or from vaccination. Regulators in different countries have a similar opinion. In the United States, revaccination should be done in eight months, in Israel – from five months, in the European Union – from six months. Approximately in the period from six to eight months from the moment of the last contact with the virus (or after the previous vaccination – RT ), the optimal terms of revaccination fit into, “the specialist said.

Earlier, Nikolai Kryuchkov, in an interview with FAN, gave recommendations on vaccinations against influenza and coronavirus.

The State Intellectual Property Office of the People's Republic of China (CNIPA) has prevented Apple from banning Huawei from using the MatePod trademark. Earlier, the American company said that the name is similar to one of those that belong to it.

Apple worried about its brands: iPod, EarPods and AirPods. The Cupertino-based company argued that Huawei “maliciously copied” the trademark, and that it could have a negative impact on society.

These arguments were not convinced by CNIPA, which ruled in Huawei's favor. The regulator added that there is “not enough evidence” to confirm that Huawei copied something. CNIPA recognized the similarities between companies in terms of “functionality, sales channel and target customers.” However, “the spelling of trademarks is different,” so their existence will not cause confusion among consumers.

Military expert Alexei Leonkov said that the Russian fifth-generation fighter Su-57 is ahead of its competitors from the United States in weapons systems, robotization, radar surveillance systems and electronic warfare (EW).

The expert said that the Su-57 is ahead of American aircraft in the number and variety of weapons already now. In addition, the fighter uses the latest technology that competitors from the United States do not have.

Leonkov noted that earlier only American F-22 and F-35 were ranked as the fifth generation of aircraft, but these fighters are not inconspicuous. At the same time, Russia, according to the expert, has obvious progress both in twin-engine cars and in single-engine ones.

The first Su-57 entered the Russian troops in 2020.

The launch of the Soyuz-2.1a rocket, which was decorated under Khokhloma, will take place at 03:00 Moscow time on 28 October. On October 25, the rocket will be taken to the launch site of Baikonur, reports the radio “Moscow speaking” with reference to “Roskosmos”.

The launch vehicle will launch the Progress MS-18 cargo vehicle into orbit. Its docking with the ISS is expected on October 30.

Earlier, the state corporation published on its website images of the package of the first and second stages of the rocket, on which stickers with Khokhloma patterns were visible. In addition, symbols in honor of the 800th anniversary of Nizhny Novgorod were seen there.

Let us recall that on October 17 the Soyuz MS-18 spacecraft with actress Yulia Peresild, director Klim Shipenko and cosmonaut Oleg Novitsky on board successfully landed on Earth. Peresild and Shipenko stayed at the station for 12 days, during which the “cinema crew” filmed footage for the film “Challenge” in orbit. The film tells the story of a woman doctor who is preparing for a flight into space on a tight schedule to carry out an emergency operation for an astronaut.

On October 22, it became known that the actors and the astronaut had completed a course of rehabilitation to the conditions of the Earth.

Young scientists from the Institute of Physical Chemistry and Electrochemistry. A.N. Frumkina, together with colleagues from the Kurnakov Institute of General and Inorganic Chemistry of the Russian Academy of Sciences, as well as from the Moscow State University. M.V. Lomonosov have developed a method for obtaining conducting nanostructures (“nanowires”), which allows you to solve all these problems. The article was published in the journal Inorganic Chemistry. The authors use the ability of organic molecules to spontaneously, the so-called supramolecular assembly using weak intermolecular bonds that hold molecules together due to a large number of contacts. It is this principle that underlies the self-assembly of complex biological objects: membranes, cells, tissues.

The nanowires were assembled from ready-made supramolecular blocks 2 nm in size synthesized from phthalocyanines – synthetic dyes of cyclic structure with semiconducting properties and widely used in organic electronics. Crown ether groups (cyclic molecules-“traps” for metal cations) were added to the phthalocyanines and coupled together in pairs with rare-earth ions. Despite the complexity of the molecular structure of an individual block, the process of obtaining nanowires from them is very simple – it is enough to add a potassium salt to them. Potassium cations bind to crown ether traps of neighboring blocks and collect them in one-dimensional stacks up to 100 microns in length. Such nanowires are practically free of defects and conduct electric current 50 times more efficiently than other known materials based on phthalocyanines.

The simplicity of the method opens up the possibility for its adaptation to the real production of new compact optoelectronic devices. “In order to connect the elements of an electrical circuit in a device for organic electronics, it is necessary to be able to lay nanowires in the desired configuration on the surface of a silicon chip,” says Alexandra Zvyagina, head of the Russian Science Foundation grant for young scientists, within the framework of which this work was carried out (Grant No. 19- 73-00025). “We found that our nanowires align themselves along the lines of force in an external electric field, and due to this effect, we easily and quickly get films with nanowires laid on the surface in a given direction.”

Self-assembly and orientation in an electric field are not all the advantages of supramolecular nanowires over traditional conductive polymers. The comparative “weakness” of bonds between molecules in nanowires becomes their strength, allowing one to solve one of the most difficult problems of modern chemistry, associated with the prevention of the release of microplastics into the environment during the disposal of polymers. Scientists from the Institute of Physics and Chemistry of Economics of the Russian Academy of Sciences have shown that ready-made supramolecular nanowires, which are stable under normal operating conditions of electronic devices, can be quickly disassembled to the original molecules in a special solvent without the formation of by-products that could damage the environment. The technology makes it possible to preserve valuable compounds containing rare earth metals in the process of recycling a spent chip and use them again to assemble a new device. Young researchers are confident that technologies based on supramolecular assembly can provide future progress in the field of “green” waste-free microelectronics, and conductive nanostructures obtained using this technology will become a reliable alternative for difficult-to-decompose conductive polymers.
