Scientists have found out why mosquitoes bite some people more often than others.

These conclusions were made by American scientists after experiments involving 64 people. The researchers placed nylon sleeves on volunteers' arms for six hours to collect volatile skin samples. Then these sleeves were placed in pairs in a chamber with mosquitoes - at the same time there were samples of two different people in it. The scientists observed which fabric would attract insects. It turned out - the one on which there are more carboxylic acids. Moreover, the leading sample was a hundred times more interesting for mosquitoes than the outsider of the list. The experiment was repeated a few months later. Some of the volunteers changed their skin care products during this time, but the attractiveness rating of their nylon sleeves for mosquitoes remained the same.

"Pillars of Creation"

The James Webb Telescope photographed the Pillars of Creation gas clusters, located at a distance of 7000 light years from Earth. Astronomers suggest that the cluster no longer exists due to a supernova explosion. However, on Earth, the first consequences of the explosion will be visible only after a thousand years.

Buddha Bot

Japanese scientists uploaded the sacred texts of Buddhism into the neural network and created the "Buddha Bot" - AI Buddha. He maintains a religious conversation with a person. You can turn to him with any question: in a difficult period of life or simply to achieve enlightenment. The application screen depicts the Buddha in the lotus position. With the help of augmented reality technology, it can be transferred to a real environment captured by a smartphone camera. You can communicate with AI Buddha by voice and text messages. The chatbot does not select answers based on the gender or age of the user.

Motorola showed the concept of a smartphone with a retractable display.

At the Lenovo Tech World event, Motorola showed off an interesting but not new concept. This is a smartphone with a screen that can be unfolded and collapsed - all you need to do is press a button. The smartphone has a retractable OLED display that can grow from 4" to 6.5" in height. So far, there are no details about the characteristics.

The craftsman has created a mod that allows you to order pizza directly from the video game TES Oblivion.

To do this, you need to find a character named Pizza Black and leave an application. So far, he only knows how to take one order - a 30-centimeter pizza with a thin crust, eight garlic bread and a bottle of lemon tea. After that, it transmits the data of a real pizzeria.

Japanese engineers have learned how to print cookies with hidden QR codes on a 3D printer.

Outwardly, it differs little from the usual, but inside there are square cavities or areas filled with dye dough. By lighting such cookies with a flashlight, you can see a QR code, which, for example, can indicate the composition and expiration date of the product.

In Spain, they created a hyper-realistic copy of the cut body of Jesus Christ.

In the Cathedral of Salamanca, a hyper-realistic copy of the body of Jesus Christ was exhibited with all the cuts and injuries that could remain on it after desecration and crucifixion. The art object was created after 15 years of detailed study of the Shroud of Turin and 3D reconstruction of the images preserved on it. A copy of the body of Christ is made of latex, silicone and human hair. Weight - 75 kilograms, figure height - 177 centimeters. Its official name is "Mystery Man". "Mystery Man" will be in the Spanish Cathedral of Salamanca until December, and then go on a world tour.

Too strict upbringing affects DNA.

Children of strict parents may be prone to depression and suicide due to the fact that they have increased DNA methylation. These conclusions were reached by Belgian scientists during a study involving 44 boys and girls aged 12-16. The researchers divided the adolescent volunteers into two groups. The first included children of "soft" parents - supportive, giving significant freedom. Secondly, boys and girls who are often punished, brought up strictly and subjected to psychological manipulation. DNA samples were taken from all children and its methylation was analyzed at 450,000 sites. Methylation has been found in everyone - it occurs in every human body. But too many modified sites are often associated with the development of depression and increased suicidal tendencies. This is exactly what the scientists found.

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.
