Windows 11

Windows 11 lost in popularity to Windows XP. The researchers came to such a disappointing conclusion. 80.34% use Windows 10, Windows 7 is preferred by 4.70% of users. 0.04% use Vista and 1.71% use 20 year old XP. But that's still more than 1.44% adoption of Windows 11.

New in HIV treatment

Immunologists have tried to achieve remission in HIV-infected patients with a cocktail of two antiviral antibodies. Antibody injections allowed trial participants to live 20 weeks without standard antiviral therapy and several more months without treatment at all. Most of the subjects then had to return to standard therapy, but in two people the remission lasted at least a year. Next, researchers will have to figure out exactly how antibodies affect the intact reservoir and look for a way to shrink it more - perhaps somehow combining antibodies with antiretroviral therapy.

Stress and gray hair

Scientists from Columbia University have confirmed that there is indeed a connection between stress and the occurrence of gray hair. However, when the stress level dropped, the hair color of the subjects was restored. For example, one of the participants went gray on vacation. Researchers attribute these processes to chemical changes in hair cells during the growth stage.

This is the largest maze in Spain. It has twelve entrances, symbolizing the signs of the zodiac. The height of the walls is 2.5 m. There are two routes through the labyrinth: easy and difficult. In the center there is a tower with an observation deck, from where you can admire the labyrinth from above.

Discovery in neuroscience

The absence of a part of the brain involved in speech processing did not stop a person from learning two languages ​​and getting a degree. Evelina Fedorenko, a cognitive neuroscientist at the Massachusetts Institute of Technology, worked for several years with a patient without a part of the brain that is involved in speech processing. Despite the lack of a left temporal lobe, she speaks fluent English and Russian, has a degree, and has had an "impressive" career. Scientists did not know before that whether the frontal lobes could form in the absence of the temporal lobes, but the experience of the patient Fedorenko showed that they can. A series of experiments confirmed that her language abilities are in no way inferior to those of neurotypical people.

New startup

Startup Space Perspective showed the interior of balloons for space tourism. The ball will rise into the stratosphere to a height of 30-40 kilometers. It will not reach outer space, which begins above the mark of 100 kilometers. The flight duration will be six hours. Space Perspective expects to organize the first launches at the end of 2024. The ticket will cost $125,000.

The negative impact of electronic cigarettes on brain health

For the study, biologists exposed lab mice to JUUL e-cigarette vaporizers three times a day, using some of the most popular flavors: mint and mango. The researchers then looked at signs of inflammation throughout the body. It turned out that the strongest changes occurred in the brain: several markers responsible for inflammation were increased there. However, the expression of inflammatory factors was seen in the colon. In the heart, scientists tracked a decrease in the level of inflammatory markers. The state of immunosuppression of the heart can make heart tissue more vulnerable to infection. In the lungs, biologists found no signs of tissue inflammation, but numerous changes in gene expression were observed in the samples.

A way to store solar energy for 18 years has been created

The technology is based on a molecule of carbon, hydrogen and nitrogen, which changes shape upon contact with sunlight. This isomer can then be stored in the liquid state for an extended period of time. The ultra-thin chip designed by scientists releases energy. According to experts, the technology they described will replace classic batteries and solar cells. They emphasized that the created closed system works without carbon dioxide emissions.

Also coming to Apple Watch 8 are advanced sleep tracking features, a medication management option, and new ways to track women's health.

Research by Japanese scientists

Japanese scientists have grown spermatozoa from embryonic rat cells. So far, such experiments have been carried out only on mice; it has not been possible to do this for other species. The resulting spermatozoa turned out to be functional - they can be used to conceive viable offspring. True, they cannot yet fertilize an egg on their own, and they do not develop without donor supporting cells. Research by Japanese scientists

Why is singing good for health?⁣ ⠀

Singing helps to get rid of stress. Scientists have discovered that when singing, endorphins are produced in the brain, a substance due to which a person feels joy, peace, good mood and increased vitality.⁣ ⁣ Thus, with the help of singing, one or another feeling can be evoked and expressed.

Interesting

Scientists have found that orangutans, like people, can use slang. The experiment was carried out on the islands of Sumatra (Indonesia) and Kalimantan. The essence of the experiment was as follows: people made new sounds that were easily and quickly identified by orangutans, and those, in turn, shouted out “slang words” in a chain reaction, trying to “be in the know” and seem “brutal”.

Japanese restaurant

A Japanese restaurant for naked people will weigh in. Visitors whose weight exceeds the average by more than 15 kg will not be able to enter the institution. Such people are not recommended to book seats in advance, since the restaurant is not going to return the money paid for entry. Guests will be provided with paper underwear. Restaurant staff will also be partially covered. Visitors are promised that the waiters will be "men with the most beautiful bodies in the world." The restaurant will open on July 29th.

Air pollution

Air pollution has caused hundreds of thousands of deaths. An international team of scientists has found that air pollution has caused more than 100,000 deaths in tropical cities. The researchers analyzed air quality data for 46 metropolitan areas across Africa, Asia and the Middle East using instruments aboard NASA and European Space Agency satellites from 2005 to 2018. In all cities, experts have found a significant annual increase in the content of pollutants that are directly hazardous to health. For example, nitrogen dioxide increased by 14 percent, fine particles by eight percent, ammonia by 12 percent, and volatile organic compounds by 11 percent.
