An underwater garage for 7,000 bicycles has been built in Amsterdam.

An underwater garage for 7,000 bicycles has been built near Amsterdam Central Station. It is located directly under the famous city canals. The garage will make it possible to remove thousands of bicycles from the embankments, which are regularly left by passengers. You can park your vehicle in it for free for a day, and then for 1.35 euros per day. According to the latest data, 835,000 Amsterdam residents make an average of 665,000 bike rides per day - that's 36% of the city's total travel (compared to 24% by car).

Trans women regained spermatogenesis after hormone therapy was discontinued.

Their partners were able to get pregnant. After hormone replacement therapy was discontinued, trans women (those who were identified as male at birth) regained the production of normal spermatozoa capable of fertilization. It was previously believed that hormone therapy leads to a lifelong decrease in the activity of spermatogenesis and infertility.

Experts named the smartest cat breeds.

The researchers conducted a series of experiments and studied how the adaptability and level of curiosity of domestic cats correlated with their mental abilities. The most intelligent were Abyssinian, Bengal and Burmese cats, as well as Cornish Rex and Scottish Fold. Good abilities were also shown by Singaporean, Siamese cats, Turkish Angora and Japanese Bobtail. However, experts note that there is as yet no standardized test to measure intelligence in cats. From a scientific point of view, there is no universal measure of "reason" in animals.

Unmanned drone ship.

The Chinese have commissioned the world's first unmanned drone ship Zhu Hai Yun, which is controlled by AI or remote operators. The vessel, 88.5 meters long, has a speed of up to 18 knots, and on board it carries dozens of all kinds of air, surface and underwater drones. They will be engaged in geodetic work, sampling and analysis, mapping and more. Primarily designed for scientific research, Zhu Hai Yun can also be used for patrolling and anti-poachers.

Archaeologists have found a mysterious burial of a child and 142 dogs in Egypt.

They discovered the burial of an eight-year-old child and 142 dogs during excavations in the necropolis of the Fayum oasis. Scientists came to the conclusion that they all died at the same time. On the remains of dogs were found traces of blue clay, which is often found in ancient Egyptian reservoirs. This suggests that they may have drowned during the flood. However, it remains a mystery why a child ended up in the same grave. He may have cared for animals, but it is even more confusing that his body was found with a linen sack over its head.

In the next 40 years, the ozone layer will recover over the entire planet.

Thanks to the phased out of circulation of 99% of banned ozone-depleting substances, the protective layer in the upper stratosphere will recover to the thickness of 1980 in 40 years. The ozone layer will return to normal in all regions of the world, including Antarctica.

The fastest internet on the planet, all of a sudden, was in Chile.

Ookla, the most popular internet speed aggregator on the planet, said that in 2022, the average speed on the planet was 74.54 Mbps. This is 28% higher than 58 Mbps a year earlier. The fastest Internet was surprisingly found in Chile - 216.46 Mbps. China, with 214.58, is in second place.

Scientists have learned to control lightning with lasers.

For the first time, they were able to control lightning using lasers during an experiment conducted in the Swiss mountains. This technology will help protect airports and high-rise buildings from electrical discharges. The experimental facility was placed next to a 124-meter telecommunications tower, which is struck by lightning about 100 times a year. The scientists fired fast laser pulses at thunderclouds and deflected lightning strikes, creating an easier path for the electrical discharge.

China recorded a population decline for the first time in 60 years.

The number of inhabitants in 2022 decreased by 850 thousand people compared to the previous year. The birth rate was only 6.77 newborns per 1,000 people, the lowest in decades.

Zoologists have found that dolphins underwater are trying to drown out extraneous noises.

Scientists from the University of Bristol have found that dolphins, when underwater noise increases, try to shout over it. They use sound signals to communicate with each other and perform joint tasks.

The world's largest aircraft stayed in the air for a record 6 hours.

The world's largest aircraft Stratolaunch Roc, whose wingspan exceeds a football field, made another test flight. The aircraft rose to its maximum height (6860 meters) and spent a record 6 hours in the air. The Roc design consists of two side-by-side fuselages, six Boeing engines and unique triple wings with a span of 117 meters. Maximum takeoff weight - 590 tons. They have been working on the ship for more than 12 years. Initially, it was supposed to work to deliver rockets and satellites into the stratosphere, but now it is a carrier aircraft for hypersonic research vehicles.

Nova introduced the Nova H1 ear-ears.

The speakers are directed towards the ears, while allowing you to hear what is happening around. Working time - 3.5 hours, and with a case - all 14 hours. The cost of the "gold" version is 695 euros, and for the silver version 595 euros. In addition, natural pearls are embedded in each of the versions.

In Italy, the head of the mafia (criminal organization) Cosa Nostra Matteo Messina Denaro was arrested.

Denaro was the last mafia boss of the first magnitude remaining at large. He has been a fugitive since 1993.

On February 2, the green comet C/2022 E3 (ZTF) will approach Earth.

In the second half of January, the comet will fly between the constellations Ursa Major and Ursa Minor and will be visible to the naked eye. The diameter is approximately 1 kilometer.

Men drink beer faster if they are in pain.

As you know, drinking alcohol increases the pain threshold and reduces the intensity of pain. Against this background, scientists decided to conduct an additional study, during which they found out that pain provokes men to significantly reduce the time between sips of the drink. It is noteworthy that the speed of swallowing beer in women did not change at all.

Trailer for James Cameron's mini-documentary dedicated to the final scene of the Titanic.

National Geographic has released the trailer for James Cameron's mini-documentary dedicated to the final scene of the Titanic. In a small film, the director conducted a full-fledged experiment in which he attracted divers, stuntmen, an expert in hyperthermia and recreated the same door - to prove to fans that Rose and Jack could not escape together on the same raft. The premiere will take place on February 5th.

China has cloned a racing horse for the first time.

The cloning experiment was carried out at SinoGene, work on it began back in 2021. The cloned foal named Zhuang Zhuang (translated from Chinese as "Sturdy") was born on June 16, 2022. The somatic cells were taken from a skin sample from a warm-blooded horse named Ursus, who came to China in 2007 from Germany. Zhuang Zhuang is already 7 months old, and there is a possibility that he will take part in the 2028 Olympics. By that time, he will be the right age. The cloning company says that the characteristics of the clone are the same as the original, but training is still necessary.

Its main feature is the continuous patrolling of a given area, interrupted only by a short recharging. If the alarm is triggered, the drone will automatically fly to look for the intruder, starting a video broadcast.

Scientists have figured out how to turn abandoned mines into gravitational batteries.

Such a system will allow you to accumulate excess energy for later use. According to the project, electric motors will raise and lower sand containers, generating electricity through regenerative braking on the way down and then using some of it on the way back. For maximum efficiency, elevators can take the load on the surface and drop it at the bottom of the shaft. In this case, they will be able to remove excess sand from below when there is an excess of energy in the network. According to scientists, one such station can store from 7 to 70 terawatt-hours of electricity.
