Scientists have predicted another version of the extinction of people.

A study by doctors from Israel and the United States showed that since the 70s, the number of sperm in semen has decreased significantly on all continents and in all ethnic groups. Specifically, on average, there are half as many of them on the planet - from 101 per ml to 49. Moreover, the rate at which the number of spermatozoa falls is also growing.

In Oregon, twins were born, who are already 30 years old.

Lydia and Timothy Ridgway were conceived and frozen in 1992. Then the embryos were sent to the national donation center. And only this year they found their parents, for which they were thawed and given birth. The biological father of the twins did not live to see the birth of children, but the current father at the time of their conception was only 5 years old.

Smartphone addiction reduces creativity, Chinese scientists say.

They measured the addiction of 48 students on the Smartphone Addiction Scale. Participants then took an "Alternative Uses" test, where they had to come up with different uses for common items. Addicts fared worse. Moreover, they have less fluent perception of information, flexibility and originality of thinking.

In Japan, introduced a robotic spider to inspect sewer pipes.

In order to simplify the work of existing workers, TMSUK has developed a spider robot to inspect sewer pipes. The SPD1 walking robot prototype was created in response to a request from a local utility company. The device has dimensions of 21x25x28 cm, weighs about 3.5 kg and is designed to inspect pipes with a diameter of 200-300 mm. The robot is remotely actuated and controlled by the operator using a game-type controller connected to the SPD1 cable. TMSUK envisions a scenario in which three robots can be physically linked together by a cable and work as a group. In this case, the lead robot will move through the pipe, the second robot will identify areas that need repair, and the third robot will perform the repair using a robotic arm holding the tool.

NASA has launched the most powerful rocket - SLS (Space Launch System).

This is one of the key stages of the Artemis mission to land astronauts on the moon after a half-century hiatus. A giant 98-meter rocket will launch the Orion reusable spacecraft into space, carrying mannequins with artificial organs to assess the effects of radiation on the body, plant seeds, fungi and algae. It will fly around the Moon and return to Earth, splashing down in the Pacific Ocean on December 11. If everything goes according to plan, then in 2024 the Artemis-2 mission will start - already with people on board, but without disembarking. It is planned to lower the crew to the lunar surface in 2025 as part of Artemis-3. Recall that the last and sixth manned landing on the moon took place as part of the Apollo 17 mission in 1972.

In the United States, laboratory meat is officially recognized as fit for consumption.

It is important to understand that this is not about meat substitutes. We are talking about real meat, which is mainly made by cloning chicken meat cells. Now, it is officially recognized as safe and suitable for human consumption.

Male fertility has halved in the past half century.

Male fertility has halved in the past half century. Between 1973 and 2018, male fertility worldwide declined by about 50%. Moreover, since the beginning of the new millennium, the figures have been falling twice as fast as before - by 2.64% annually. These conclusions were reached by Israeli scientists after a meta-analysis of 800 studies on male infertility. According to the World Health Organization, 10-15% of families in the West cannot have children due to the infertility of one of the spouses. Most of them lose their fertility at the age of 40-55.

Remains of fish baked 780,000 years ago have been found in Israel.

At the site of the ancient people of Gesher Bnot Yaakov in northern Israel, archaeologists have found the remains of fish baked on a fire 780 thousand years ago. This find was the earliest evidence of the use of fire for cooking. It is 600 thousand years older than the previous one.

Young monkeys, like children, brag to their parents.

Chimpanzees, like people, can attract the attention of relatives not for any purpose: to ask for food or help - but simply to show off. Like children pointing their fingers at a passing car or a toy in the sandbox to their parents just to share information. Canadian scientists came to these conclusions during the observation of chimpanzees. For the first time in history, zoologists managed to film how a young monkey shows off to his mother a found green leaf.

Chinese customs officers accidentally found an insect unknown to science.

In the province of Guangdong, Chinese customs officers found a cockroach unknown to science. It arrived in the country with a cargo of timber from French Guiana in South America. Customs officers handed over the discovered insect to scientists. Whether it was alive is not specified. Biologists did a DNA analysis and studied the morphological features of a cockroach. They didn't match any known creature. It turned out that the insect is a new species from the Latindia class. The scientists published their findings in the Chinese Journal of Molecular Biology.

Tuvalu will create its own digital twin.

The island state of Tuvalu will create its digital twin because of the threat of complete flooding. The tiny island nation of Tuvalu, which is located near Australia, may sink to the bottom of the ocean by the end of the century due to climate change. The government of the country decided to create a digital copy of Tuvalu along with the sights in order to preserve its history and culture. It will be uploaded to the metaverse. Already now, at high tide, about 40% of the atoll-capital of Funafuti goes under water. After 80 years, the ocean can completely absorb the entire group of islands.

Scientists have learned how to make computer chips from mushroom skins.

Such a chip, according to scientists, is much easier to dispose of when it has served its useful life. After testing the resulting chip, the team concluded that the skin was almost as good as traditional plastic bases. After 2,000 bends, not a single crack formed on it. But there are still difficulties. For example, in the production of such chips, additional tests must be carried out to make sure that the skin works as it should. Nevertheless, scientists consider their development promising and plan further research.

Up to 1.35 billion people could lose their hearing due to too loud music on headphones.

The researchers analyzed more than 30 scientific papers on this topic over the past 20 years. In the studies analyzed by scientists, a total of about 20 thousand people participated. It turned out that in 24% of cases, listening to music with headphones can be called dangerous. In the case of concerts, this figure reaches 50%. The researchers also found that listening to loud music was associated with "changes in hearing thresholds." This is due to the fact that sensory cells are damaged in humans, and it takes years to restore them.
