Japanese company Iwatani Giken launched a hamster into the stratosphere to a height of 23 km.

The rodent was placed in a sealed chamber 50x60 cm with optimal pressure and temperature. The ball gained altitude in an hour at a speed of 6.3 m / s, and then smoothly descended into the sea. During the flight, the hamster even slept from time to time and did not experience any inconvenience. The startup wants to make manned ascents into the stratosphere one of the entertainment for people, and the hamster experiment is proof of success.

The electric car from Mercedes-Benz drove 1202 kilometers without recharging.

This is more than all other electric vehicles available. Vision EQXX traveled 1.2 thousand kilometers between Germany and the UK on a single charge. The journey took 14.5 hours at an average speed of 83 kilometers per hour, in some areas the electric car accelerated to 140 kilometers per hour. What's more, Mercedes stated that the air conditioning was on for about eight hours during the trip. But the air conditioner, as it is believed, can very strongly discharge the battery of an electric car. With this trip, Mercedes set a new record. The longest range electric car available on the market is the Lucid Air (830 kilometers), while the Tesla Model S can travel about 650 kilometers.

Interesting facts about Greenland.

In Greenland, some prisoners are allowed to keep the keys to their own cells, leave places of detention during the day to go to work/school, and even hunt wild birds and seals with guns.

Creepy music.

Strange, creepy horror movie music is performed, for the most part, on one unique instrument called a waterphone (translated as “voice of water”).

The Chinese spend half their lives in traffic jams.

Once in Beijing, the world's largest traffic jam was recorded, 100 km long, which lasted 10 days.

A paralyzed racer drove down the track in Goodwood at the annual festival of speed.

Sam Schmidt, former Indy Racing League driver, paralyzed in a 2000 crash. However, technology works wonders - he already moves in an exoskeleton. And with the help of breathing and turning his head, he can control the McLaren 720S Spider in racing mode.

NASA has asked to suspend the sale of lunar dust that was fed to cockroaches for the sake of experiment

Dust collected during the Apollo 11 mission in 1969 was given to insects to eat to determine if it contained pathogens. Cockroaches fed on moon dust were then studied at the University of Minnesota by entomologist Marion Brooks. According to the results of her research, she did not find any negative effects of insects eating moon dust. The dust was fed to cockroaches to check whether the regolith contained some kind of "lunar plague" dangerous to humanity.

For the first time in history, a private spacecraft will fly to the moon.

NASA and startup Rocket Lab are planning to launch a private satellite, CAPSTONE, using a private Electron rocket. It is clear that this does not have serious scientific goals, but nevertheless, for the first time in the history of mankind, the Moon can submit to a small private firm by the standards of the industry. Start is in the next few days.

The locust will help invent a revolutionary cancer test.

Dogs and other animals with an incredibly sensitive sense of smell are able to sense the illnesses of people in the earliest phases. It is expensive to train so many dogs, so scientists have gone the other way - they are trying to "hack" the brain of locusts, which in theory can also feel the disease. If you can understand how these areas work, you might be able to mimic the process to create quick tests, even for cancer.

Scientists from MIT: one brewery is able to clean the water of an entire city from heavy metals.

Inactive yeast can be an effective and inexpensive way to remove lead from drinking water sources. One gram of this yeast can remove up to 12 milligrams of lead in less than five minutes. The research team calculated that there was enough waste yeast thrown away from one brewery in Boston to clean up the city's entire water supply. Such a completely sustainable system would not only purify water, but also solve the problem of waste disposal from production.

The giant sunspot has doubled in size in a day. It is directed towards the Earth.

The largest sunspot AR3038 doubled in size in just a day - now it exceeds 30 thousand kilometers in diameter, that is, 2.5 times the size of the Earth. Solar activity can affect the operation of satellites and even terrestrial electronics. Now the star is approaching the maximum of the current cycle of activity, it is expected around 2025.

People choose friends by smell.

A team of scientists from the Weizmann Institute of Science in Israel studied how smells affect friendships. It turned out that people are more willing to build friendships with those who smell the same as them. It was possible to prove this with the help of an experiment. First, the researchers analyzed the smells of the volunteers. They chose pairs of close friends of the same sex, whose friendship, they said, developed very quickly. The scientists also took odor samples from the control group, which included people who did not know each other. The analysis showed that there is a lot in common between the smells of friends.

Satellites measuring the magnetic field around the Earth began to fall due to strong solar radiation.

Since last fall, the Sun has been spewing more and more solar wind, flares and coronal mass ejections at an increasing rate. And the upper layers of the Earth's atmosphere, as well as satellites, have already felt the consequences of this. The vehicles descend to the atmosphere at an unusually high speed - up to 10 times faster than before.

Tourism helps treat dementia

Scientists have come to the conclusion that new experiences that a person receives while traveling have a positive effect on brain function. This provides cognitive and sensory stimulation, and the need to adapt to new conditions while traveling makes the brain work harder. Tourism also involves a lot of movement, which is also useful for various diseases - physical activity is directly related to mental well-being. The authors of a new study propose to rethink the role of travel in medical practice and treat it not just as entertainment, but as therapy.

The robot failed the tolerance test.

He was sexist and racist. American scientists pasted photographs of faces of people of different sexes and races on cubes, and then asked the robot to sort them and put them in a box. There were more than 60 tasks in total. For example, the robot needed to find a doctor, a criminal, a housewife, and so on. There were no clues in the photographs. It turned out that the robot is sexist and racist. For example, he considered black men to be criminals 10% more often than white men. The system also appointed Hispanics as cleaners 10% more often than Europeans. Doctors in the understanding of AI are men of any nationality, but not women. Experts fear that biased robots are already at work in factories and homes - it could be uncomfortable for people.

Electricity consumption is breaking records around the world.

Just last week, Texas reported an absolute record for electricity consumption. And today China announces a similar event. The country's premier even hinted at the reopening of coal-fired power plants to solve the problem.

Caffeine makes you spend more money on shopping.

Drinking caffeinated drinks before and during shopping - coffee, tea, energy drinks, hot chocolate - makes people spend more money and buy products that bring pleasure: for example, home decor. American scientists came to such conclusions after five experiments involving almost 800 people. The researchers analyzed the receipts of customers who used caffeine before shopping and those who drank drinks without caffeine. This effect of caffeine is seen in those who drink less than two cups of coffee a day. In people who drink more, it weakens.

A "heated pool" appeared in the Pacific Ocean.

German scientists have said that there is a large "heated pool" in the northeast Pacific Ocean - an abnormally warm zone that appeared as a result of human activity, and not natural climatic changes. It provokes local sea heat waves. Because of this, animals die in the ocean and droughts occur on the coast. Over the past 20 years, 31 marine heat waves have been recorded in this region alone - in the period from 1982 to 1999 there were only nine. More than 100 million fish and half a million birds have died in the United States as a result. The number of sea lions, humpback whales and other animals has fallen.

Rammstein shakes the earth at his concerts.

The seismograph, which works at the DESY research center in Hamburg, recorded abnormally high noise from the Volksparkstadion stadium, where the band's concert took place. And it was not just a sound, but transverse ground vibrations, similar to an earthquake. This was probably caused by the stomping and jumping of the audience and the explosions of the pyrotechnics that Rammstein use during concerts.
