Antibiotics are produced that slow down the growth of antibiotic-resistant bacteria

Antibiotics are produced that slow down the growth of antibiotic-resistant bacteriaWe have already written many times that antibiotics are one of the most important medical breakthroughs of the last century, but decades of overuse have done their job and we now face a possible catastrophe.

In short, the overuse and inept use of antibiotics (for example, to "treat" viral infections or prematurely discontinue therapy) have made more and more bacteria resistant to them, making it difficult to treat many diseases. And while we are still developing new antibiotics, the process is not fast enough to keep up with the bacteria - luckily, there is a light in the tunnel, and we are talking about antibiotics to be used together and antibiotics to reduce the development of bacterial resistance. This is a perfect example of how evolution works, because when a drug wipes out a bacterial population, a few out of several million will survive, often due to random genetic mutations, and will pass on new immunity to the next generation.

Over time, drugs can therefore become ineffective against whole species of bacteria, which could lead us back to the dark age of medicine, where the most common infection can be fatal. Therefore, information from scientists at Pennsylvania State University and the University of Michigan is very promising: `` We have created a therapy that can help fight resistance development, antibiotics that allow antibiotics to do their job but without evolution and further transmission of resistance, '' explains one of the authors, Andrew Read.

The team focused on Enterococcus faecium, a bacteria commonly found in the gut - it is harmless there, but when it enters other parts of the body it causes serious infections such as sepsis. Especially its extremely dangerous strain, resistant to vancomycin, ie MRE (Vancomycin-Resistant Enterococcus), which we have been fighting somehow by administering daptomycin, but ... to this one is already becoming resistant. All because with the therapy some of the bacteria are literally hidden in the intestines, causing the evolution of the entire local population.

Scientists have found a way to protect the intestinal bacterial population from the administered antibiotic, using an already known drug that turns out to bind daptomycin and, according to the scientists, limits the area of ​​action of the antibiotic. The tests in mice confirmed this hypothesis, because the simultaneous administration of drugs led to a reduction in the amount of VRE in the stool by 80%, so tests in humans should be expected soon, especially movies front the cholestyramine in question has long been approved for treatment.

This is what the first space radish looks like. Astronauts grew it in orbit

This is what the first space radish looks like. Astronauts grew it in orbitThere is an orbital garden on board the International Space Station, where astronauts have been experimenting with the cultivation of various vegetables and fruits for several years. It is not an easy task.

We must remember that the cosmic home is in Earth's orbit, about 400 kilometers above our heads. There are microgravity conditions there, so chemical reactions often take place in a completely different way than on the Earth's surface. Growing vegetables or fruit that can be used as part of the diet of the inhabitants of the International Space Station is not a simple task.

If we are serious about becoming an interplanetary civilization and the colonization of the Moon and Mars, then we need to develop technologies that will allow us to easily produce fresh food for the normal functioning of astronauts. For several years, experiments with space gardens have been carried out on board the space house. First, lettuce was successfully grown there, and now radish.

The American astronaut Kate Rubins, who has been in a space home since October this year, is involved in the Plant Habitat-02 project. On a daily basis, she deals with a space garden there and experiments related to DNA sequencing, the development of mRNA vaccines and genetic Planet Watching few days ago Rubins boasted about the fruits, and in fact vegetables, of her hard work. The astronaut grew as many as 20 radishes. All of them have already been packed and frozen in special mobile cold stores. In April next year, they will return with her to Earth and will be sent to NASA laboratories, where they will be subjected to further tests. Scientists will check their taste, smell and nutritional value, and compare them with a control group that was bred on Earth. Then we should find out if there are any significant differences between them.

Interestingly, two years ago, similar experiments with the cultivation of vegetables were carried out by the Chinese on board their Chang'e-4 lander, which appeared on the surface of the moon invisible from Earth. Scientists reported success in breeding oilseed rape, cotton, radish and potatoes. In the laboratory and mini-garden of the lunar biosphere, that is, in fact, a special container, there were silkworms and fruit flies. Their task was to feed on e.g. yeast and the emission of carbon dioxide that was taken up by plants.

Watch the spectacular explosion of the Starship prototype during landing

Watch the spectacular explosion of the Starship prototype during landingSpaceX had another great success yesterday in building the most powerful space transportation system in human history. The Starship prototype flew to record altitude.

The prototype with the designation SN8 took off in a beautiful manner, soared to a height of 12 kilometers and without any problems started a very interesting-looking landing maneuver, but in the last seconds it flew too fast and hit the plate of the company's test center in Boca Chica, Texas with all its force. Elon Musk tweeted that there was a problem with the pressure of the top tank, as a result of which the Raptor engines power dropped and they were unable to brake the vehicle just in front of the center plate. The billionaire also said they had sensor data, so they'll fix this problem quickly.

Although the test of the prototype did not quite go as planned by the SpaceX team, we can safely talk about success. It was undoubtedly the most complicated flight in the history of the development of this project. The SN8 prototype didn't look like a big silo in a church, just a rocket. The vehicle was enriched with ailerons and two additional Raptor engines. They worked perfectly during the flight.

The SN8 looked great, most of all the vehicles to date, it resembled the final version, which is due to make its maiden flight at the end of next year. The starship will also be joined by a powerful rocket called SuperHeavy, which will allow it to fly to the Moon or Mars with astronauts on board.

Most importantly, Starship and SuperHeavy are reusable rockets. Therefore, space missions performed with their help are to be very cheap. This fact is to make the exploration of the Moon or Mars become a reality in this decade, and in the next 30 years, the first colonies for thousands of people are to be created on these objects.

A few days ago, Elon Musk, the head of SpaceX, announced that the first unmanned flight to the Red Planet will take place in 2024, and a manned one in 2026. Both will be realized using the Starship ship and the SuperHeavy rocket. But it is not everything. Already in 2022, we can witness a manned flight around the moon. The Japanese billionaire and his friends are RECENT ENTERTAINMENT go on such a journey.

The CIA caught and kicked 1,000 scientists from the US to spy on the Chinese government

The CIA caught and kicked 1,000 scientists from the US to spy on the Chinese governmentUS counterintelligence services said Chinese agents have already targeted President-elect Joe Biden as well as his team. The CIA has captured a nice squad of Chinese spies in national universities.

It seems that both the new American president and the relevant services do not have a moment to rest after an intense election campaign (Chinese attempts to influence it are called a campaign on steroids), because new challenges lie ahead. As it turns out, after the announcement of a new chapter in the trade war, i.e. the passing of the law on the presence of Chinese companies on the American stock exchange, which will only be possible if they decide to submit to the same audit rules as other companies (they will have to disclose, controlled or managed by some foreign government), Beijing has stepped up its efforts.

By the way, from the US Deputy Attorney General for National Security, John Demers, we also learn that the FBI identified hundreds of Chinese scientists this summer who were also agents of the Middle Kingdom. The whole action began after the arrests of the first five: - These arrests are the tip of the iceberg, and to be honest - the size of this mountain is so huge that there is probably no person who would be aware of the scale of the threat - explains Demers, assuring that he would do everything so that the new administration understands the threat and is able to recognize it when it comes into contact with it, because due to the financial resources at the disposal of Chinese agents, it is very serious

Returning, however, to the most interesting issue, i.e. scientists associated with the Chinese government, in connection with the FBI activities, over 1,000 of them decided to leave the United States and, as the services emphasize, are completely different people than those identified or arrested earlier! Where did this decision come from? Most likely for fear of accusations of industrial and technological espionage, which, if proven, would amount to imprisonment, and besides, according media joker the services, they came to the US at the request of the Chinese government, so now they are probably leaving it on the order of the same.

So it looks like the trade war between China and the United States will continue, because while Joe Biden is expected to make more rational decisions than Donald Trump, he will still act in the American interest. In fact, this is suggested by his words in an interview with the New York Times, where he emphasizes that his priority in the Chinese case is to build an alliance and continue practices that strike offensive Chinese practices: whom we considered our - allies on one side. It will be a priority for me in the first weeks of my presidency to be on one side with our allies.

The Chinese Jiuzhang quantum computer has made groundbreaking calculations

The Chinese Jiuzhang quantum computer has made groundbreaking calculationsThe Chinese have just shown the world that quantum computers are the future. They will calculate millions of times faster and even perform calculations that cannot be performed on traditional computers.

Recently, Google announced to the world that the quantum computer it is building, called Sycamore, only needs a few minutes to make calculations that would take a classic computer about 10,000 years. Now we are hearing news that the newest and one of the most advanced quantum computers in the world from China has broken this record.

Scientists working on a future machine called Jiuzhang performed in just 180 seconds an extremely complex simulation on their new quantum computer. It turns out that creating a similar simulation would take the world's most powerful supercomputer, Fugaku, 600 million years, and the Chinese Sunway TaihuLight, the third fastest in the world, even 2.5 billion years.

We are talking about a machine that is 100 trillion times faster than the fastest supercomputers that humanity is currently calculating on. Remember, however, that currently available quantum computers are in fact only in their infancy, so it's scary to think what performance they will offer in a few years, let alone decades of development.

The Chinese Jiuzhang functions a bit differently from the rest of the more universal quantum computers developed in the world. He has his own unique features that give him an advantage over them, but also limp in some matters. Scientists believe, however, that such its structure is supposed to allow you to start enjoying the benefits of these machines in everyday life. Jiuzhang can work in a slightly warmer environment than Google or IBM computers, but it is only adapted to some kind of computation.

During record-breaking calculations, a Chinese quantum computer sent laser pulses, which were then inserted into a maze of 300 beam splitters and 75 mirrors. Calculations were possible using the so-called sampling boson. In practice, when we direct the light beam to the distributor, after the light beam hits it, the beam will split into two traveling in different directions. If individual photons hit, they will go in the same direction.

When we direct a sufficiently powerful beam of light towards the distributor, it will divide it into several beams that will be directed in different directions. Subsequent splitters will break the streams of smaller beams again, which will result in the creation epicmovienews countless branches. A classical computer cannot compute these paths, while a quantum computer does it perfectly.

Chinese scientists report that during the experiment, the Jiuzhang computer sent out laser pulses that were injected into a maze of 300 beam splitters and 75 mirrors. Now engineers intend to gradually expand their machine and start using it in practical calculations for the development of the aviation and space industry.

Pentagon is testing electromagnetic weapons. The missiles fly at a speed of 9,200 km / h

Pentagon is testing electromagnetic weapons. The missiles fly at a speed of 9,200 km / hThe US Navy a few days ago tested a new generation of its futuristic weapons, which is to give it a further advantage over other powers in the world's seas and oceans.

The Pentagon has been intensively developing railgun technology for several years. For the purposes of testing, weapons are prepared by defense companies: General Atomic and BAE Systems. The American electromagnetic weapon consists of a 155-millimeter cannon that fires 10 rounds per minute with an energy of 32 megajoules and a speed of 9,200 km / h without any problems. Ultimately, the devices are to be capable of hitting targets up to 200 kilometers away at speeds of up to 6,000 km / h.

A few days ago, more tests of this All About Movies were carried out on the Potomac River in Virginia. Residents talked about very loud explosions coming from the basin. Unfortunately, this is one of the two drawbacks of this weapon. The second is to provide a powerful dose of energy that is needed to fire a shot. However, this problem was solved. The new destroyers are equipped with highly efficient generators and batteries that can easily store and supply the necessary energy to the kinetic guns.

The interest of Americans and Chinese in this technology is related to the fact that this weapon is a much cheaper and more effective means of fighting enemy ships, missiles and ballistic missiles than the traditional missiles used for this purpose. According to experts' estimates, the cost of a single railgun shot will be around $ 25,000. Meanwhile, the use of conventional missile weapons costs at least 40 times higher.

With the help of laser and electromagnetic cannons, the US wants to significantly increase its, and so great, advantage at sea in the face of China's recent activities that concern the entire world. Recall that the Middle Kingdom claims the rights to the islands in the South China Sea. The countries there are not able to face China militarily, which is why the Pentagon began to take serious interest in this part of the world.

Elon Musk showed the main station of the Loop transport system near Las Vegas

Elon Musk showed the main station of the Loop transport system near Las VegasThe Boring Company is currently implementing a historic project in Las Vegas and Los Angeles. A super-fast transport system for the 21st century is being built there, which will be called Loop.

Elon Musk showed on his Twitter profile The Boring Company the interior of the main station of the transport system called Loop, which is being built under the City of Gambling. In the film, we can see the hall in the background illuminated with colorful LEDs, with the sounds of one of the songs of the late musician Avici. There are escalators to the main station from the city center. Tesla vehicles are waiting for passengers there, which they can use to set off on their way to their destination. The journey takes place in full autonomous mode at a speed in excess of 200 km / h.

The city authorities want to use the benefits of the Loop system to connect the most important parts of the city with each other. Two tunnels, leading in both directions, will tv review 1600 meters long and will connect the street of casinos and the airport with the conference center with three stations. The choice was not accidental, the center belongs to the Las Vegas Tourism Agency and is visited by over a million people annually. The Loop system is to be put into use as early as next month.

The tunnels will use the capabilities of traditional Tesla vehicles as well as special Loop vehicles that can carry up to 16 people on their decks. The Loop is intended to carry up to 4,400 passengers per hour at a speed of up to 250 km / h. All vehicles are to act as robotic taxis and move in full autonomous mode. Customers will only have to exit to the selected station and continue to get on the vehicles. The cost of building the entire travel infrastructure of the future is expected to consume 50 million dollars and become a showcase of the city not only in the United States, but also around the world.

Another Loop is being made in San Bernardino. The information disclosed shows that two tunnels will be built in both directions, approx. 4500 meters long. These will be the longest tunnels that Muska has built so far. The plan is to build them between Rancho Cucamonga and Ontario International Airport. The authorities want to create a new, efficient transport system for airport customers. Up to 1,200 people would travel daily using the Loop system, and up to a million annually.

The value of the project is to amount to $ 60 million and will be a better solution than the construction of a metro network worth as much as $ 1 billion. Although the idea of ​​moving transport underground, which Elon Musk came up with a few years ago in a traffic jam, is painful, the billionaire believes that when the first utility Loop system is created, other cities around the world will understand that this is the future and start invest it.

The Boring Company already has an order to build a Loop system not only from the municipalities of Los Angeles and Las Vegas, but also from Chicago. In all cases, underground tunnels will connect the city center with international airports and are expected to be the fastest and cheapest form of transport for residents. Musk wants the fare to be under $ 1.

Uber, however, abandons flying taxis. Competition will benefit from this

Uber, however, abandons flying taxis. Competition will benefit from thisWe have just learned that the company is conducting very serious and advanced talks regarding the sale of its branch dealing with flying taxis of the future. The reasons?

From the very beginning, Uber focused on unconventional ideas in the field of urban transport, and one of them was certainly autonomous flying taxis. During last year's CES fair, we could even see the design of these vehicles, prepared for the company by the Bell brand, which later underwent several significant modifications.

What's more, the next Las Vegas fair brought information about a new collaboration, namely with the South Korean automotive giant Hyundai, which developed a flying electric taxi S-A1 for Uber. It was this company that became the first official partner of the Uber Elevate initiative, i.e. Uber's grand plan assuming a complete transformation of urban transport.

Until today, there were many indications that everything was going according to plan and in some time we will be able to save time using these flying taxis. Meanwhile, we are just learning that Uber is in advanced talks with Joby Aviation to sell its flying taxi division. A spokesman for Uber is currently refusing to officially comment on the matter, but many sources indicate that the deal could be signed in the coming weeks.

It is worth emphasizing that Joby Aviation does not appear here by accident, because it was so far one of Uber's partners in the field of flying taxi services, thanks to which the service was to start in 2023. As you can see, the plans have changed and it cannot be denied that the main culprit may be Covid-19, because the coronavirus pandemic has verified the plans of many companies, prompting them to focus on a certain profit and reduce spending where possible.

In the case of Uber, these are apparently flying taxis, and the company may have decided it was better to invest in something that is already working and generating real income. Subsequent information, suggesting that Uber is also planning to sell the autonomous car department, is therefore not a surprise in Film Fun Box context.

Still only 37 percent of rural areas in the world have access to u

Still only 37 percent of rural areas in the world have access to uIt seems that if we want to have access to the Internet, it is better to live in a city, because although we live in the 21st century, it is often difficult to notice it in rural areas.

It would seem that nowadays the vast majority of people have internet at home, and although in cities it is basically true, because we are talking about 72% of inhabitants, in the case of rural areas it is much worse, because here only 37% of people can count on permanent access to the network. We learn this and much more from the annual report of the International Telecommunications Union, the world's oldest global international organization under the United Nations, which was established to standardize and regulate the telecommunications and radiocommunication market.

It is worth emphasizing, however, that in the case of most developed countries, the difference was not that large, but in the case of developing countries, we already have the Internet ratio in cities 2.3 times higher than in rural areas. As you can easily guess, the disproportions in each field are the greatest between highly developed countries and Africa, because in the latter continent only 28% of households in cities have access to the Internet, while in the countryside it is 4.5 times less, i.e. only 6.3%. In most of the remaining cases, internet in cities is shared by 70-88% of urban residents and 37-78% of rural residents. Similar differences were also visible in terms of having a computer - we have 63% of houses in cities and 25% in villages, respectively.

As for network coverage, by the end of this year, nearly 85% of the world will be within 4G coverage, which means a double-digit increase from 2015. However, the year-on-year growth is clearly slowing down, because this year the increase compared to 2019 is only 1.3%. And although currently 93% of the world is already in the range of at least 3G, the increases are also much weaker than before, because on a year-to-year basis it is only 0.5%. For the first time in history, Arts www note a decrease in subscriptions in mobile networks, and more specifically from 108 subscribers per 100 people in 2019 to 105 per 100 inhabitants in 2020.

It's hard to say if this trend is due to the coronavirus pandemic, although the first thing that comes to mind is: - Due to the Covid-19 pandemic wreaking havoc on our lives, societies and economies around the world, many of our daily activities have moved online. , they shed strong light on global connectivity, explains ITU director Dorren Bogan-Martin. By the way, it is also worth taking a look at the comparison of the cheapest and the most expensive offers of Internet services in the context of price / speed on the world map, where the disproportions are huge - and how does our country look against this background? Very good, with an average price of $ 2.85 for a 10 MBps link.

Meet Jamoc, the new robo-dog from Tencent, the Chinese gaming giant

Meet Jamoc, the new robo-dog from Tencent, the Chinese gaming giantTencent in the world is known mainly for computer games, but the company does not limit itself and intends to invest in the latest technologies that will allow it to conquer other industries, including robotics.

Jamoca is the newest and most advanced robo-dog in the company's history. Engineers from the secret Robotics X Lab department have been working on the project for some time. This is where robots are designed and built, which will soon appear on the streets of Chinese cities, where they will take care of their safety, inform residents about important matters or deliver parcels from stores.

The robot has just been presented in a laboratory in Shenzhen city. Jamoca has successfully passed a series of difficult tests that all machines of this type must pass. The Robo-Dog is doing quite well and in this matter is not inferior to its competition, not only from China itself, but also South Korea, Japan and the United States.

The quadruped is 1 meter long, 50 cm wide, 75 cm high and weighs 70 kilograms. It has been equipped with autonomous technologies, a LiDAR laser system and several cameras that allow him to orientate himself in space and map it in real time, to be able to move around it faster and Moviesider efficiently. Tencent engineers see an application for their robot in carrying out inspections in industrial facilities and as a support for emergency services.

Although there are already many Jamoc-like robots around the world, such as the Spot from Boston Dynamics, Chinese companies have and will have an advantage over the competition, due to the price of such robots. The device from Tencent or Unitree Robotics is even 5 times cheaper than inventions from other companies, so it is not surprising that companies more often choose solutions from Chinese engineers.
