A river almost 500 kilometers long was found under the ice of Antarctica.

British scientists have found a large ice-covered river 460 kilometers long in the west of Antarctica. In terms of the length and volume of transported water, it is comparable to the Thames. The discovered river accelerates the melting of the southern ice cap - because of it, glaciers slide into the ocean faster. In the near future, climatologists will study other parts of the continent in order to accurately determine the contribution of under-ice rivers to the destruction of glaciers. The accelerated melting of the ice of Antarctica will affect the polar regions of the planet and mountain glaciers. Already, these areas are 4-9°C warmer than in past centuries.

The Mylo device uses AI to monitor swimmers in the pool.

The device is installed in one of the corners of the user's pool. It is equipped with cameras located above and below water, as well as a water pressure sensor. Mylo is available for pre-order now for $999. Coral Smart Pool emphasizes that the system should be used as an additional layer of security and not as a substitute for human control.

NASA has published a picture of the smiling Sun.

Dark spots that look like a mouth and eyes are coronal holes. These are regions of the magnetic field from which the solar wind rushes into space. The accelerated particles will reach the Earth on October 29-30.

Exactly 76 years ago, mankind received the first photographs of the Earth from space.

In October 1946, the United States launched a modified German V-2 rocket to a height of 120 kilometers to take the first photographs of our planet from space.

Engineer Matt Mikka created a Tesla that runs on gasoline.

He installed a gas generator in the ex-electric car, this allowed the car to be charged not only while parking, but also while driving. The blogger managed to drive the car 2500 km without recharging, however, the loud noise from the generator attracted the attention of the police.

Mexico has completely legalized same-sex marriage.

In Mexico, the state of Tamaulipas legalized same-sex marriage - now homosexuals can enter into unions in any of the 32 regions of the country. The full legalization of gay marriage in the state took seven years. The authorities of Tamaulipas supported the decision with 23 votes, 12 deputies opposed, two abstained. The Supreme Court declared the ban on same-sex unions unconstitutional back in 2015. Since then, one state after another has legalized gay marriage. Guerrero and Tamaulipas delayed the decision the longest.

The French have developed a champagne that can be drunk in space.

Cordon Rouge Stellar is the world's first alcoholic beverage produced specifically for astronauts. The bottle releases bubbles with liquid, and the astronauts catch them with a special glass. But the chip is not only in the bottle, because ordinary champagne does not release bubbles in zero gravity, which is why it is almost soundless, and this drink was specially made with a sharper and more pronounced taste.

Chinese scientists turned a dove into a cyborg and used the energy of the sun to control its flight like a drone.

Scientists were able to control the bird for two hours - almost one and a half times longer than during previous experiments. Conventional commercial drones are not capable of staying in the air for that long. The controller sent signals to the pigeon's brain that stimulated the nerves. Thanks to this, the bird could be directed in any direction. The device was wirelessly connected to the base and powered by a solar panel the size of half a smartphone. In total, five pigeons participated in the testing of the technology. They followed commands with 80-90% accuracy. Guided pigeons can be used in search and rescue, reconnaissance and anti-terrorist operations.

How many burgers a week can those who want to save the planet eat.

Experts from the World Resources Institute and other organizations have prepared the State of Climate Action 2022 report. It talks about the measures that people and governments need to take to reduce the negative anthropogenic impact on the climate. 1. Meat consumption should be reduced to the equivalent of two burgers a week. This will reduce the impact of agriculture on the climate. 2. Public transport should be developed six times faster - this will reduce car emissions. 3. The process of abandoning coal must also be accelerated six times. Worst of all are the use of gas, steel production, the disappearance of mangroves, the use of cars, emissions from agriculture. To move the global economy to a low-carbon basis, an additional $460 billion will need to be allocated annually over the next ten years, experts say.

Invisible Man.

The University of Maryland has developed a sweater that turns a person invisible in the eyes of algorithms that recognize people. Artificial intelligences are trained to recognize objects, and the print on the sweater makes it difficult to do this using AML methods.

Samsung smartphones will have a "maintenance mode".

This was done for the convenience of repair - including the mode, the ability to access personal data, photographs and other details is cut off. But at the same time, service workers can easily fix the phone and check all the functions.

In Israel, they made a reactor that allows you to grow 12 times stronger cannabis.

By "strength" is meant the effect itself. According to the manufacturer, a gram of their cannabis will have 12 times more impact on the patient than naturally grown.

Engineers have created shoes that increase walking speed by 2.5 times.

A roller-like device that can be attached to almost any shoe. The blocks are equipped with an electric motor, each has 4 wheels. Moonwalkers has an intelligent control system and adapts to human movements. So, walking speed can reach 11 km/h.

Washing machine for people.

The Japanese company announced a washing machine for people: the device will clean, massage and dry the owner in 15 minutes. The task of the device is not so much in comfortable bathing as in relaxation - while the process is going on, you can relax to soothing music and enjoy beautiful pictures.

There has been a long-awaited progress in the field of earthquake prediction.

California users said on Tuesday that the Shake Alert app was able to alert them to tremors in just a couple of seconds. Not much time, but better than nothing - at least people had time to get to the shelter.

Scientists have suggested that our brain works like a quantum computer.

The capacities and electrical processes of the brain are already well understood. But powerful computing power is still a mystery. A group of scientists from Texas published a paper that analyzes the similarities between quantum computing algorithms and how the brain works. Thus, it may turn out that quantum computers have been around for a long time. In our heads.

Blood oxygen sensor test.

The journal Digital Health published a study by independent scientists who tested the effectiveness of the blood oxygen sensor on the new Apple Watch. On average, the error in comparison with professional equipment was 1.2%. Very worthy.

The benefits of video games for children.

American scientists conducted a study on more than 2,000 children and found that video games have a positive effect on children's brain development. Playing children: - Have better motor skills. - Remember information faster, easier and more accurately. - Showed higher brain activity in areas related to concentration and memory.

Elon Musk showed the giant Mechazilla in action.

The founder of Tesla and SpaceX posted a video on his Twitter page showing a giant tower with a mechanized arm called Mechazilla. It will be used to "catch" the Super Heavy launch vehicle and the Starship spacecraft on landing.

Chemists have uncovered the secret of Stradivari violins.

Italian chemists studied two violins by Antonio Stradivari and found out that the master covered them with a composition of animal proteins before varnishing. Among them was collagen. This layer filled in the smallest irregularities, influenced the resonance and improved the sound of bowed instruments. This is not the only secret of Stradivarius. A few years ago, Taiwanese chemists found a mineral preservative made from calcium, copper, aluminum, sodium, and zinc on the master's tools. Most likely, Stradivari did not just apply it to the wood - the preservative was part of the soaking of the wood.
