The Dagestan plant Concern KEMZ officially presented the new Russian twin-engine multi-purpose aircraft Alfa-KM. The aircraft is a significantly improved version of the MAI-411 aircraft; for example, due to the use of composites, the Alfa-KM aircraft turned out to be 250 kg lighter than its predecessor. The Russian aircraft - Alfa-KM, is an analogue of the European CS-23 and American FAR-23 aircraft, the demand for small aircraft is growing and its production is now especially relevant. The aircraft is intended for air transportation, air tourism, patrol and other uses in small aviation.
The aircraft is made from Russian components; it was previously reported that the Austrian Rotax 912S engine is used, but there is no data on what it is now. In case of engine failure, the aircraft has a parachute rescue system. Companies from Malaysia, India and Turkey already intend to purchase Dagestani aircraft. The maximum take-off weight of the aircraft is 1250 kg, but it is capable of carrying 4 people over a distance of up to 1500 km, with a cruising speed of up to 250 km/h, at a flight altitude of up to 3000 meters.

New Volga S40, K30 and K40 cars are shown in Russia. At an exhibition in Nizhny Novgorod, Russian Prime Minister Mikhail Mishustin was shown new cars of the revived Volga brand. Reportedly, they plan to produce three car models: Volga C40 - class D sedan, Volga K30 - class C crossover, Volga K40 - class D crossover. There is no official information yet about the partner who is helping with the revival of the Soviet car brand. The likely donor for Russian cars is the Chinese cars Changan Raeton Plus, Changan Oshan X5 Plus and Changan Uni-Z. It is worth noting that the design of Chinese cars in recent years has become even better than European ones. All three cars use a gasoline engine with a power of 188 horsepower and a torque of 300 Nm. Presumably a seven-speed automatic transmission and a 1.5 liter engine. The cars are equipped with intelligent driver assistance systems, and Russian services are integrated into the multimedia system. Production of the machines will begin in 2024, and from 2025 - in full cycle mode.

In the Russian village of Bogoslovka, Omsk region, a curious incident occurred: an unknown man flew to a village store to do some shopping in a Robinson R44 helicopter manufactured by the American company Robinson Helicopter. It is worth noting that an hour of helicopter flight costs hundreds of times more than purchased products. The Robinson R44 helicopter is considered one of the safest, thanks to its simple but reliable design. It first took to the air in March 1990; in total, about 6,000 helicopters of this brand were produced and sold.

Boeing said it is working on a new quality issue for the Boeing 737 MAX and Boeing 787 Dreamliner. It is worth noting that the problem with the quality of Boeing aircraft can already be called a detective story, since two informants who reported them have already died under mysterious circumstances. Bloomberg published a report from Boeing's quality control inspector. Sam Mohawk said: Boeing lost 400 defective parts that - either intentionally or by mistake - could have been installed on new planes. Records of where and how defective components were stored disappeared from internal archives.
On June 18, a hearing was held in the US Senate, at which Boeing CEO David Calhoun spoke and answered questions from congressmen who criticized the corporation for numerous problems with the quality of aircraft. According to media reports, the head of Boeing had to justify himself in the Senate because of his salary of more than $30 million and the concealment of spare parts; he also apologized for problems with flight safety.
Problems with the Boeing 737 MAX became known 5 years ago, the same problems with the Boeing 787 Dreamliner, in short, they are all related to the acceleration of aircraft production, a problem with parts from suppliers and savings on wages for engineers, designers and programmers. Boeing has said it continues to refine and improve its aircraft manufacturing process, but scandals have plagued the company, which has already impacted its financial performance.

The Soviet, the last surviving reusable spacecraft "Buran", known as "Baikal", will be restored in Russia. The collection of the museum complex in Verkhnyaya Pyshma has been replenished with the manned spacecraft "Buran" created in 1993, it will be restored. The first apparatus of the "Buran" program flew on November 15, 1988 and is now destroyed. The second Buran spacecraft, known as Burya, never flew in space and is stored at Baikonur. The third Buran spacecraft, whose flight planned for 1994 also did not take place, the program being closed at that time, will be placed in a museum near Yekaterinburg after restoration. The reusable Buran spacecraft looks like the American Space Shuttle, but unlike it, it had the ability to land in automatic mode and emergency ejection of the crew. Buran was also capable of long flights, up to 30 days, orbital maneuvering, controlled descent and aircraft landing at a specially equipped airfield. Due to lack of funding, after the collapse of the Soviet Union, the Buran program was transferred from the Ministry of Defense to the Russian Space Agency and was closed in 1993.

Elon Musk showed prototypes of two new Tesla products at once: the Cybercab robotic taxi and the Robovan driverless van. The Optimus humanoid robot was also shown. The Cybercab robotic taxi can be used not only for personal use, but also rented out, making money on it. Tesla has assembled at least 50 Cybercabs and plans to launch mass production no later than 2027. The price of one Cybercab taxi for entrepreneurs will be less than 30 thousand dollars. There is no steering wheel or pedals in the Cybercab, since human control is not provided at all, the car operates completely in unmanned mode. The Cybercab car will be charged inductively, without the need to connect to the network. Musk said that autonomous cars will be 10-20 times safer than those controlled by people. A ride on a Cybercab will cost 20 cents per 1.6 km, for comparison, on a bus it costs $ 1.

The Robovan driverless van will be able to transport 20 people, it also has a numb steering wheel and pedals, it can be converted into a cargo version. The Optimus robot attracted the most attention from the public, in the future it can become one of the family members. They promise that the Optimus robot will be able to clean the house, walk the dog, mow the lawn, water the plants, set the table, wipe the dust, play with children and much more. Optimus robots are already being adapted for work in production and as auto mechanics.

The prototype of the Russian unmanned mainline truck L5 was presented by Navio in Moscow. Navio is the former SberAutoTech, since 2020 it has been developing autonomous driving technologies and other products with artificial intelligence. The prototype of the L5 truck was initially designed by Navio to be fully autonomous. In terms of autonomy, the truck corresponds to the L5 level, which is full automation. The truck has a machine vision system, which includes several cameras, radars and LiDAR sensors. Instead of a windshield, the L5 unmanned vehicle has a huge screen. It is needed to display various information: duplicating turn signals, indicating the speed of movement, etc. The unmanned truck is capable of saving up to 15% of fuel and reducing the cost of transporting goods by up to 30%. Cargo with the L5 truck will be delivered faster, since the unmanned vehicle does not need to stop for rest and can work around the clock. In September, Navio, together with KamAZ, for the first time released Russian trucks without a person in the driver's seat on the M-11 Neva highway.

Drinking coffee could cut the risk of heart death by one-third – but only if you drink it in the morning, a study suggests.

Research on over 40,000 adults who were tracked for more than a decade found that those who started the day with a cup fared far better than those who drank no coffee.

The study is the first to look at the impact of the time coffee is consumed on health outcomes. Previous research has had mixed findings about the impact of coffee on heart disease.

Some studies have suggested that moderate consumption may cut the risk, while high consumption may increase it.
