A drone has flown over the summit of Everest for the first time.

The flight was made by the drone DJI Mavic 3. According to the characteristics, it can fly at an altitude of up to 6,000 meters above sea level and withstand temperatures down to -10 °C. Therefore, for the flight, a team of Chinese photographers 8KRAW made changes to the design of the drone. The highest altitude that the drone managed to reach after the upgrade exceeded 9,200 meters.

The bees arranged the numbers from left to right.

Previously, this feature was found only in vertebrates. Honey bees are able to evaluate numbers and arrange them in space from left to right depending on the magnitude. The researchers believe that the bees are guided by a mental number line, and the arrangement of numbers in it is associated with the reference number on which the bees were previously trained.

In Denmark, launched a storm simulator Beat the Storm.

This is an attraction thanks to which you can feel what a hurricane is like. The wind speed during the simulation is 160 km/h, which corresponds to a category 2 storm on the Saffir-Simpson scale, there are five of them. Through various special effects, they recreate the conditions of a storm in the desert, mountains and other places. The project was launched to raise awareness about extreme weather and teach people how to move around during a hurricane.

Scientists have finally learned how to recycle all types of plastic.

They have developed a catalyst (accelerator) for the chemical decomposition of all types of plastics. After the interaction of the catalyst and plastic, propane is obtained. The new catalyst was made from a porous material with cobalt nanoparticles - zeolite. During the penetration of microplastic particles into the pores of the zeolite, the polymer chains are broken at the same point for all types of polyethylene and polypropylene tested, as a result of which the plastic is converted to propane.

Now you can spend the evening with a glass of wine in virtual reality.

All thanks to Swedish scientists. They have developed a technology that allows you to smell in VR. The aromas are mixed with each other in special valves and served through a tube, which the user must bring to the nose. The researchers have already created a small game where you have to guess the type of wine by smell. Alas, try the drink in VR until it comes out, the technique has not yet reached this point.

Did you know?

Steve Jobs suffered from compunophobia - the fear of buttons and buttons on clothes. It is believed that this is why he sought to ensure that his Apple company created devices devoid of buttons - devices equipped with touch screens and electronic keyboards.

"Dark Spot" of Paris.

In 1973, the first and last skyscraper, the Montparnasse Tower, grew in the capital of France. The gloomy building did not fit into the general image of romantic and dreamy Paris so much that the locals even achieved a complete ban on the construction of skyscrapers in the city. This is how the building, which was supposed to become a symbol of the modernity of Paris, became a dark spot on the canvas of the city.

Four-legged robot goalkeeper.

Engineers have trained a four-legged Mini Cheetah robot to act as a football goalkeeper, analyzing the ball's flight path and jumping to intercept it. Robochepard weighing nine kilograms completes the movement in just 0.9 seconds. He is trained in three movements: shift to the side, jump and dive - jump to the side, followed by a fall to intercept the ball flying into the bottom corner. When a ball is thrown, the robot determines its position using a depth camera, and then selects the desired movement and its trajectory. After that, the low-level controller calculates the torques so that the interception is successful.

The heaviest bony fish in the world was discovered off the coast of Portugal.

She weighs almost three tons. The carcass of a dead moon-fish weighing 2,744 kilograms was caught off the coast of the Azores - this is an absolute record for bony fish. Its height is 3.5 meters, and its length is 3.6. Marine biologists weighed the moon fish using a winch and industrial scales, and then opened it up. They took samples of DNA and stomach contents. Moon-fish lives in tropical and temperate waters of all oceans. Their exact number is unknown. In spring and summer, the population in the northwest Atlantic is estimated at 18,000 individuals.

Plasmonic resonance will help determine the maturity of the whisky.

British chemists have proposed a new whiskey quality control method based on the formation of gold nanoparticles due to the reaction between specific chemical components of the drink with an aqueous solution of hydrogen tetrachloroaurate. The nanoparticles manifest themselves as a peak in the optical transmission spectra due to plasmon resonance. The method works at room temperature and is very fast, making it easier for whiskey blenders.

Earth may seem uninhabited to alien astronomers.

To determine the conditions on exoplanets, terrestrial astronomers analyze the properties of their surface and atmosphere using infrared and ultraviolet radiation. The spectra of the Earth, its thermal radiation, can correspond to both favorable characteristics for life and unfavorable ones. At the same time, it seriously differs in different parts of the planet and in different seasons. That is, it is impossible to obtain a single representative sample of the Earth's thermal radiation spectrum. This was shown by analysis of data from an infrared probe aboard NASA's Aqua satellite. This means that alien astronomers from a distant galaxy may not understand that there is life in the solar system. It will be very difficult to observe the dynamic Earth, analyze and interpret the data obtained.

The largest artificial waterfall.

The largest artificial waterfall is built into the Liebu International Building skyscraper in the Chinese city of Guiyang. An hour of operation of the waterfall costs the company 100 euros and recently, in order to save money, it is included only for special events.

Chinese scientists have taught cows to produce human milk.

According to foreign media, scientists from China conducted an experiment by introducing proteins inherent in the human body into the embryos of Goldstein cows. The scientists then placed these fetuses in surrogate cows. In the future, it can be used for artificial feeding of infants.

In California, they made the largest camera in the world with a resolution of 3200 MP.

At the National Accelerator Laboratory SLAC (Stanford Linear Accelerator Center - Stanford Linear Accelerator Center) in Menlo Park, California, the construction of the largest chamber in the world is almost completed. Its resolution is 3.2 GPU, or 3200 MP. To make it all work, a lens with a diameter of 1.57 meters is used: The minimum shutter speed is 15 seconds. This length is due to the size of the matrix, which must be closed when creating a snapshot. In fact, these are 189 separate CCD matrices, each of which has a resolution of 16 megapixels. All matrices are combined according to the formula 3 × 3, that is, nine pieces in each square block, of which there are 21 pieces.

Artificial intelligence has broken a 50-year-old record in mathematics.

Multiplication of two 4x4 matrices usually consists of 64 steps. Volker Strassen in 1969 came up with an algorithm that reduces the number of steps to 49. The AlphaTensor neural network from DeepMind found a way to reduce the number of steps to 47. And in 5x5 matrix multiplication, the neural network reduced the number of steps from 98 to 95. Considering that this is one of the most popular operations in modern computers, video cards and other devices will soon become a little faster.

Women are better than men at crossword puzzles and playing scrabble.

Indicators of verbal fluency and verbal episodic memory are higher in women than in men. This means that they quickly recall and select words, especially those starting with a particular letter. Therefore, women are better at solving crossword puzzles and playing scrabble. These conclusions were reached by Norwegian scientists after a meta-analysis of 168 studies over the past 50 years, in which a total of 350,000 people participated.

Queen released an unreleased single in 1989.

The musicians of the Queen group released a single with the real vocals of Freddie Mercury - Face It Alone ("Face it alone"). The song was recorded while working on the 1989 album The Miracle. After 30 years, it was restored in the studio with the help of modern technology. The composition was rediscovered by the band's archivists, who studied old recordings while working on the reissue of The Miracle. The musicians called Face It Alone "a little gem from Freddie".

Endangered penguins get rid of their firstborn for the survival of the species.

Scientists have figured out why endangered two-egg-laying crested penguins drop the first and only hatch the second, which emerges about five days later. It turned out to be a strategy for the survival of the species. The first egg is formed in the body of the female when she is still heading to the nesting sites by sea, so it is small. The second is already on dry land. It is larger, which means that the chick hatched from it is more likely to survive.

iPhone 14 treats rides as an accident.

The rescue service has already received more than 6 calls from the amusement park, when the owners were just riding a roller coaster. Therefore, the company asks to turn off the phone when visiting the amusement park.
