Kombucha bacteria can survive on Mars.

An international team of scientists sent a kombucha into outer space - it was grown for a year and a half on the outside of the ISS. After that, they were returned to Earth, reactivated and cultivated for another 2.5 years. As a result of the experiment, the microbial ecology of kombucha cultures was disturbed. But the cellulose-producing bacteria Komagataeibacter survived. This means that bacterial cellulose is most likely responsible for the survival of microorganisms in extraterrestrial conditions. That is, it can serve as a biomarker for alien life. Also, on the basis of bacterial cellulose, it will be possible to make a protective layer on items needed by the future space colonizer.

Microplastics were first found in the fresh snow of Antarctica.

Prior to this, particles were found only in sea ice and surface water bodies of the continent. Microplastics were present in all 19 samples taken from the Ross Ice Shelf. On average - 29 particles per liter of melted snow. This is more than in the nearest sea and ice. Near the bases of polar explorers, the concentration of microplastics was even three times higher. Scientists have found 13 different types of plastic. The most common is PET. They make bottles and clothes from it. Microplastics could have entered Antarctica by air from other parts of the world, or they could have been brought to the continent by research teams.

In China, a man taught his husky Lucky how to cook while he is away

Through a remote home monitoring system, the owner asks the pet to turn on the slow cooker, in which he put rice before leaving.

That's the memory!

Horses have great memories. They can remember the offender for life, but they also do not forget their friends.

Importance of coffee in Yemen and Arabia.

Initially, coffee was considered in Yemen and Arabia as a miraculous medicine and was consumed only on the advice of a doctor. Many viewed it as a brain tonic or as a way to stimulate religious visions.

About tigers.

The skin of tigers is actually striped, just like their fur. In addition, no two fur colors are the same.

Zipline taught drones to hear planes and avoid collisions with them.

The company has developed an acoustic system for detecting other aircraft for drones. It uses microphones and allows you to detect other devices within a radius of two kilometers, as well as automatically rebuild the flight path to avoid a collision.

The Stargazer plane will take passengers from Japan to the United States in just an hour.

Aerospace startup Venus Aerospace presented a visualization of its future Stargazer hypersonic aircraft. Its advertised speed is about Mach 9, which allows the crew and a small number of passengers to get from Tokyo to Los Angeles in just one hour. Stargazer will take off using engines, but when it reaches the edge of space at an altitude of 52 kilometers, it will switch to "rocket mode". The plane is designed to carry 12 passengers, and its speed exceeds 11,025 km/h, which is almost 9 times the speed of sound.

In Saudi Arabia, they decided to invest a billion dollars annually in the development of life extension technology.

The Saudi royal family has decided to invest a billion dollars annually in the Hevolution Foundation, a non-profit organization. She is looking for methods to combat aging and develops life extension technologies. The royal family's money will make the Hevolution Foundation the world's largest funder of aging research. The organization will distribute grants for the development of anti-aging drugs and clinical trials. It is expected that researchers will find a means to delay the onset of diseases, which will be available to the masses.

People are born with moral guidelines already built in.

These conclusions were reached by Japanese psychologists in the course of experiments with eight-month-old children. The kids were shown on the computer screen an animation with two multi-colored balls. One of them offended the other. In another video, a stone was falling on a ball. The children were able to control the computer system using eye-tracking technology. When they had the opportunity, they sought to punish the aggressor ball and drop the stone on it. It turned out that infants who still cannot talk were punishing the antisocial aggressor. This indicates that humans may have developed a tendency toward moral behavior over the course of evolution.

Unsociable people have a higher risk of dementia, scientists say.

They came to this conclusion when they analyzed neuroimaging data from more than 30,000 people from the UK Biobank. Scientists have found that socially isolated people have less gray matter in areas of the brain responsible for memory and learning. Next, the researchers used modeling techniques to explore the association of relative social isolation and loneliness with cases of dementia. After assessing other risk factors, such as chronic diseases, lifestyle, and the presence of depression, scientists found that people who are unsociable are more likely to develop dementia by 26%.

In Britain, robots appeared - waiters.

Amid staff shortages, restaurant chain Bella Italia has adopted BellaBot robots from China's Pudu campaign. The robot can recognize human speech, conduct a simple dialogue and carry up to 40 kilograms.

In five years, scientists will be able to create "love potions".

An anthropologist from the University of Oxford, said that in five years "love potions" will become a reality. According to her, already today there are opportunities for the development of "love drugs". Such remedies will include oxytocin, the hormone that is responsible for attachment. And for unfortunate lovers, it will be possible to create “medicines” based on antidepressants. The main problems with the production of such products are related to ethical issues, but the financial component should outweigh them.

White water lilies.

Water lilies are one of the most ancient flowering plants on our planet. The leaves and flowers of white water lilies are covered with a substance that repels any dirt, so they never get dirty. Based on them, paints with similar properties were developed.

Sad statistic.

There are currently 160 million orphans in the world. This is the highest figure in history.

Height and depth.

Everest is the highest point on Earth (8848 m), but it does not compare with the deepest point on Earth, the Mariana Trench in the Pacific Ocean, which is about 10994 m deep.

Killer mosquitoes.

Mosquitoes are the deadliest animal in the world: because of the diseases they carry, they kill more people than any other creature.

Chickens lived in trees in the jungle until people tempted them with rice.

British scientists have refuted the theory that people raised chickens for food as early as 10,000 years ago. The researchers conducted a radiocarbon analysis of bird bones found in 600 locations in 89 countries and told their version of domestication. According to them, the chickens lived high in the trees and came into contact with humans only after they began to grow rice.
