According to the source of the agency, the reason for this decision was a series of incidents with convertiplanes. It is emphasized that this will also affect machines located in Japan.

The US military in October 2018 deployed five of its CV-22 Ospreys at the Yokota Air Force Base, which is located within the Tokyo prefecture. By 2024, a total of ten such devices were to be deployed there. Prior to this, 24 more Ospreys were stationed on the southern Japanese island of Okinawa, where they are used by the US Marine Corps. The Japan Self-Defense Forces also purchased several of these machines from the United States, in total, Japan planned to purchase 17 Osprey convertiplanes.

Over the years of operation, many incidents have been recorded with American convertiplanes. In particular, in 2012, two cars crashed in Florida and Morocco; in 2016, the incident occurred in the Persian Gulf zone: then a marine was killed. In August 2017, a tiltrotor crashed off the east coast of Australia. Numerous minor accidents with the CV-22 Osprey regularly occurred in Japan, which caused serious concern among the local population.

Kuwait will build the most pedestrian city in the world

The architectural company URB presented a project for a metropolis called XZERO. This city, according to the idea of ​​its creators, should become the most pedestrian in the world: it will be possible to move in it only on foot, by bicycle or electric buggies. Thus, it is planned to reduce emissions of harmful substances into the atmosphere and preserve the environment for future generations.

According to the project, the city will be made in the form of a flower, the “petals” of which are residential areas. The central area is planned to be divided into zones, each of which has a specific function, for example, medical or educational. About 100 thousand people will be able to live in XZERO, and the city will also provide 30,000 “green” jobs.

More than 65% of the metropolitan area (about 16 square kilometers) is dedicated to open spaces, including land for urban agriculture (community gardens, bio-domes, aquaponics and vertical farms), recreation areas, rainwater-permeable sidewalks, sports fields and courtyards. There is also a 35 km running track and a 9 km equestrian track that connects to the equestrian center.

URB said the project has an estimated cost of US$15 billion and is scheduled to begin construction in 2024. The XZERO metropolis in Kuwait is expected to be ready by 2034.

The whitest paint in the world just got better Now

The unique white paint, created by scientists at Purdue University, was recognized in the Guinness Book of Records in 2022. The unique composition is able to keep the surface cool, reducing the need for air conditioning.

Now researchers at Purdue University have developed a new compound that is thinner and lighter, ideal for removing heat from not only cars but other vehicles, including trains and planes.

“Everyone has contacted me, from spacecraft manufacturers to architects to clothing and footwear companies,” said Xiulin Zhuang, professor of mechanical engineering and paint developer at Purdue University. “They basically had two questions: where can I buy it and can I make the layer thinner?”

The unique paint uses barium sulfate nanoparticles that can reflect 98.1% of sunlight, as well as cool outdoor surfaces by more than 4.5 degrees Celsius relative to the environment. However, for the coating to work effectively, its thickness had to be at least 400 microns.

Thickness of old and new layer

Scientists experimented with other materials that could scatter sunlight. The latest paint formula includes hexagonal boron nitride as a pigment. This substance is most often used in lubricants. The resulting composition is able to meet all the declared parameters and reflect up to 97.9% of sunlight when applied in a layer with a thickness of 150 microns

This battle will be legendary Canon is determined to compete

ASML has almost a monopoly in the market for lithographic equipment for the production of semiconductors. And now the Japanese manufacturer Canon intends to compete with it. A plant for the production of new lithographic equipment will be built in Japan. The estimated investment will amount to $345 million, and production will start in the spring of 2025.

This battle will be legendary: Canon is determined to compete with ASML in the lithographic equipment market.  She has already created a new technology.  for this

It is important to note that for the production there will use a technology called nanoprinting lithography. It eliminates the need for EUV lithography (deep ultraviolet lithography), which requires a lot of energy and is expensive. EUV lithography machines only produce ASML.

Canon’s new technology will reduce the cost of production due to the fact that nanoprinted lithography can reduce production costs by up to 40% and energy consumption by up to 90%.

Note that the technology of nanoprinted lithography was developed more than 10 years ago, it allows you to create schemes for 10 nanometers with a potential reduction to 2-3 nanometers. However, implementation issues forced the market to switch to EUV lithography. If the technology can prove its worth, this can lead to a significant reduction in the cost of microelectronics.

Earlier it was reported that the US authorities require ASML Holding NV not to supply equipment for the production of chips to China.
