It is planned to complete construction in 2028
In Spain, the unique smart city of Elysium City will be built. This settlement will become not only a new tourist attraction, but also the first new generation city in Europe.
The first smart city in Europe to appear in Spain as early as 2023. It will have both residential premises and tourist facilities, in particular a railway station, a Disney-style theme park, a 40,000-seat football stadium, several resorts and much more. Also, free Wi-Fi will be available throughout Elysium City.
As conceived by the developers, Elysium City will be consistent with the UN's sustainable development goals. Among them are clean energy, responsible consumption and quality education. The smart city will be built in two stages near the city of Castilblanco in the autonomy of Extremadura in southwestern Spain.
The first phase of construction, which will be completed in 2023, involves the construction of four hotels with a casino, a water park and a Disney-style theme park, high-speed rail, several restaurants, shopping and entertainment centers, a golf course, a stadium and city services.
It is planned that in Elysium City there will be up to two thousand residential units. These neighborhoods will be equipped with green areas with bike paths and health paths, equipped with intelligent solar-powered street infrastructure, smart street lighting and digital bus stops.
At the second stage of construction, which will be completed in 2028, new luxury hotels, a horse riding center and the Formula 1 racing track will appear in the city.
Also, smart kiosks with public transport schedules, weather forecasts and various warnings will be installed throughout the city. During the first year of operation, the city expects to attract 4.5 million visitors.

The robot moves through the blood vessels.
A worm-like robot that can travel through the brain will help treat stroke. He will cleanse blood vessels from deadly blood clots with a special thread.
 
This writes the Chronicle.info with reference to medikforum.ru.
Scientists have developed a tiny robot resembling a worm that is designed to treat ischemic strokes. The robot moves through the blood vessels and cleans them from blood clots, that is, blood clots that disrupt the blood supply to the most important organ in the human body. This robot has 0.5 mm wide postings, and it is controlled through a magnetic field due to a special program on the computer. Moreover, this can be done outside the special room where the patient is. Although the robot has not yet been tested in humans, engineers have proven its functionality in overcoming miniature obstacles, as well as in full-size human brain models.
Engineers hope that one day this robot will treat stroke patients, when the speed of medical care is of primary importance. The faster a person with a stroke receives this treatment, the less damage to his body will follow. Scientists from the Massachusetts Institute of Technology in Boston are working on the robot, and it is reported that the length of the robot is only a few centimeters. It is made of a flexible mixture of nickel and titanium, placed in a shell of a special lubricating hydrogel, which helps it to push through the vessels without damaging the tissue.
Scientists have identified the danger of baked vegetables
Engineers said that this robot can be introduced into the patient’s body by injection, and its further movement will be controlled by magnets. However, the robot also has its own internal motors. Finally, he is also able to carry medicines to the site of damage in the brain, or he will be equipped with a laser to break down any of the most complex blood clots that impede blood circulation.

Graphene helps protect against mosquito bites.
Despite the fact that summer is drawing to a close, mosquito bites (and other unpleasant insects) can be forgotten until the next year, but it’s too early to hide the means for scaring away the “nests” for the winter. However, it is likely that after some couple of years you can take advantage of a truly high-tech protection against mosquito bites. And this is not about another "miracle spray", but about a substance that will cover your skin with an ultra-strong layer of graphene, which no mosquito will bite through.
Today, various sprays and ointments that repel insects are common. Although manufacturers claim that these products are completely safe, each such substance contains a warning that it is highly undesirable to prevent it from reaching the mucous membranes or eyes. In addition, these products rarely have a pleasant smell and are absorbed into clothing, which also cannot be called pleasant.
 
However, a team of researchers from Brown University in Rhode Island suggests using graphene films to protect against insects. If you suddenly forgot, then just in case, we recall that graphene is a material whose structure is "sheets" consisting of carbon atoms. Carbon atoms are located in one plane and thus graphene has a thickness of only one atom. Graphene is the thinnest and most durable artificial material in the world. In addition, it also has good electrical and thermal conductivity, which allows it to be used to create new type of electronic devices. But now a little about it.

Scientists from Rhode Island have created a special gel based on graphene that can be applied to skin or clothing. During a series of experiments, it turned out that at the moment when the graphene film is wet, insects simply can not bite through it. If the film dries, then in this case some mosquitoes can still bite through it. However, the number of mosquitoes that sat on the skin of the subjects was minimal. Scientists attribute this to the fact that graphene does not allow mosquitoes to "see" a person, not letting out as much heat as in his absence.
"This use of graphene against mosquitoes will help reduce the negative effects of these insects on human health associated with the development of a number of infectious diseases," said Dr. William Souk, director of Brown University in Rhode Island and lead author of the work. In addition, the use of carbon materials can reduce the use of pesticides to repel insects.
Ultra-safe "quantum Internet" one step closer to reality
According to scientists, their discovery can serve as an impetus for the creation of disposable graphene films applied to the skin and even special anti-mosquito clothes. It is also possible that graphene films will help in the fight against other insect vectors of diseases. However, at the moment, graphene production is still expensive, but its cost is gradually decreasing. So it is likely that very soon the unique material will finally find its application

In the city of Queensland, drones using artificial intelligence, find crocodiles that are approaching swimming people.
Letters are written about this.
Drones developed by Little Ripper Group and the University of Technology Sydney can detect up to 16 different species of marine life, including sharks.
The inventors emphasize that the system provides an accuracy of 93%.
Drones are equipped with sirens, speakers and floating devices that can be reset to swimmers if they are in danger.
Dr. Serge Witch of the John Moores University of Liverpool called the idea “fantastic.”
 “This is a great use of drones. If this helps to increase public safety, it is really useful, ”he said.

The airship era ended in 1937, when the passenger Hindenburg caught fire and died during the landing. This disaster was not the largest, but it turned out to be the last straw: they refused the dangerous mode of transport, despite all its efficiency. Perhaps now is the time to return to zeppelins - already at a new level and with new technologies. No wonder many companies in the world are already developing their transportation systems using such devices lighter than air, writes naked-science.ru.
Julian Hunt and his colleagues, some of whom published in Energy Conversion and Management: X, evaluated some of the prospects for air cargo shipping. Their concept is based on truly large vehicles; the authors write about airships ten times larger than the Hindenburg, which totaled 245 meters in length. In theory, this will provide an increase in carrying capacity by three orders of magnitude even in comparison with the Hindenburg, which could take on board up to 100 tons of payload.
Rising to a height of 10 to 20 kilometers, such giants can be transported by the force of the polar jet stream - a narrow and powerful stream that stably blows in the upper troposphere. In the temperate latitudes of the Northern Hemisphere, it is directed from west to east and reaches an average speed of 165 km / h. According to the calculations of Hunt and his colleagues, having straddled this stream, huge airships will be able to make a full trip around the Earth in 16 days, transferring tens of thousands of tons of cargo and practically without spending energy. A similar route in the Southern Hemisphere will take 14 days.
Thanks to modern materials and technologies, huge cargo airships can become much safer than the Hindenburg, whose shell was made from the guts of animals - today it can be made from carbon fiber. On the other hand, the buoyancy necessary for traveling with the wind can still be provided only by light gas. The only economically accessible option for it today remains the same hydrogen, the flammability of which was so vividly demonstrated by the Hindenburg. And if the accident does happen, it’s scary even to imagine what the explosion of a thousand-ton Zepellin with a hydrogen cylinder of kilometer length will turn out to be.
