They believe that the ban on fireworks during Diwali restricts their freedom of worship.

From blows to the head, the skull becomes stronger.

After blows to the head, the bones of the skull become thicker and stronger - this is how the body prepares for new injuries and protects the brain. These conclusions were reached by Australian scientists in the course of experiments on rats. How much thickening of the bones protects the brain is not yet clear. More research is needed.

Scottish scientists have come up with a hearing aid that reads lips even through a mask.

For this, artificial intelligence is used - the radar scans the movements of the lips and determines which sound they are characteristic of. For open faces, the accuracy is 95%, for closed faces, 83%. The scanner will help people hear well both in normal conditions and in noisy environments. Prior to this, the effect of a cocktail party for the hearing impaired was provided by devices that read lips with the help of a camera. But the video recording of the interlocutors could violate their privacy.

By 2050, 16% of people worldwide will be over the age of 70.

People aged 70-90 are the fastest growing population in Europe, Asia and the USA. In 1950, only 5% of the world's inhabitants were elderly; by 2050, the figure will rise to 16%. Such conclusions were reached by an international group of scientists, among whom were experts from the Laboratory for the Analysis of Population Health Indicators and the Digitalization of Healthcare.

Positive officially helps to achieve results.

The paper, published in the journal Proceedings of the National Academy of Sciences, notes that study participants who believed exercise would help them get better performed better. And those who were not told anything were lower in the ratings. According to scientists, believing in the result is useful not only when doing physical work - it also affects mental work in the best way.

A city in the Netherlands is the first in the world to ban meat ads.

Dutch Haarlem will become the first city in the world to ban meat advertising in public places. The law will come into force in 2024. The deadline was postponed due to already existing contracts with manufacturers. The measure should help fight the climate crisis. Meat products in a city of 160,000 cannot be advertised on buses, at bus stops, city lights, or billboards. The ban will also affect the promotion of fossil fuel consumption - advertising of cars with internal combustion engines and flights for the holidays.

Dentures have learned to create from cellulose.

By mixing cellulose nanocrystals with a polymer, scientists have obtained a gel that can be used to create dental implants. The resulting composite was found to be stronger and stiffer than some types of bone and harder than conventional aluminum alloys. The material has a microstructure, like mother-of-pearl - brick-building, which prevents the formation of cracks.

Wine turned out to be not as safe a drink as previously thought.

British scientists have found that drinking a bottle of wine a week increases the risk of developing cancer as much as 5-10 cigarettes. And stronger, wine has a negative effect on women.

The blood of the astronauts found signs of DNA mutation.

American scientists from the Icahn School of Medicine at Mount Sinai analyzed the blood of 14 NASA astronauts. The samples showed signs of somatic DNA mutations. They can increase your risk of developing cancer and heart disease. Most of all mutations occurred in the TP53 gene - it produces a protein that suppresses the tumor. Also in DNMT3A - this gene is often mutated in acute myeloid leukemia. The results of the study do not mean that astronauts will definitely get sick. The data must be taken into account when planning long-term expeditions to deep space.

Due to the crisis, a British vegan restaurant has decided to serve meat.

In Taunton, the capital of Somerset, popular vegan restaurant Mango Tree has decided to add meat dishes to the menu due to the crisis. While the institution is closed for renovation, it will soon return in a new format. The restaurant's customers are dissatisfied with the decision of the owners, who blame the economic crisis for everything. Mango Tree said they lost customers due to a drop in living standards - almost no one comes to the restaurant, there are still orders for delivery.

In the Netherlands, they created an AI that determines COVID-19 by voice.

The funny thing is, the algorithm does this more accurately than existing strokes. Application accuracy is 89% for positive and 89% for negative cases. For a verdict, it is enough to breathe deeply into the phone, cough and read a short sentence.

Supernova explosion.

The Setonix supercomputer has generated a detailed image of a supernova explosion, which is located 10-15 thousand light-years from Earth. The Setonix supercomputer is equipped with more than 500 AMD EPYC Milan processor nodes with 65 thousand cores. However, despite the high performance, it took him 24 hours to process such a massive amount of data.

Engineers have learned how to control the smartphone screen without contact.

Chinese and German engineers created the GhostTouch device. It can remotely simulate touching the touch screen with your finger. The device works due to the design features of touch screens and their susceptibility to electromagnetic interference. Vulnerability can also be exploited by criminals. Theoretically, they will be able to unlock a smartphone, connect to Wi-Fi, open malicious content, or answer a call from their number for wiretapping. But scientists believe that the technology is unlikely to be widely used - there are certain difficulties. At the same time, in the future, smartphone manufacturers will be able to develop algorithms for recognizing false touches.

Мouse embryo models.

US researchers have created stem cell models of mouse embryos that have a beating heart, as well as the basis for the brain and all organs in the body of a mouse. Now they are developing a similar model for the development of the human embryo. If these methods prove successful in the future, they could be used to develop synthetic organs for transplantation. mouse embryo models.

The agricultural robot Solix Sprayer autonomously searches for and destroys weeds.

Developed by Solinftec, the Solix Sprayer autonomously navigates its way through crop fields. It uses a set of built-in sensors to scan every plant it passes over from root to leaf. If the onboard Alice AI system detects a weed, then a herbicide is selectively applied. The robot also creates a digital map of the field showing where weeds have been found and treated. One robot is capable of processing up to 40.5 hectares of agricultural land per day. In addition, thanks to a lighting system and a battery charged by solar panels, the Sprayer robot can work 24 hours a day. In its current form, the Solix is ​​optimized for use on crops such as wheat, soybeans and corn. In US trials, the technology has reduced the use of herbicides by 70%.

Hormone therapy has improved the cognitive function of people with Down syndrome.

French scientists in the course of experiments with mice found out that the GnRH hormone is important for the activity of neurons in the brain of animals. Then the substance was administered to volunteers with Down syndrome. After that, their cognitive functions improved. Participants in the experiment received GnRH every two hours for six months. During this time, hormone therapy stimulated the growth and activity of neurons in areas of the brain associated with cognition. Five of the seven participants in the experiment began to better understand the instructions for action and the shape of three-dimensional objects. Also, regular injections of GnRH corrected the functioning of the sense of smell. However, there were no side effects.

Engineers have created cyborg cockroaches to inspect hazardous areas.

Japanese engineers have created cyborg cockroaches that can be controlled remotely using a solar-powered wireless micromodule. Insects will inspect dangerous and hard-to-reach areas. To do this, you will need to put additional sensors in the hybrid's backpack: for example, radiation dosimeters. The cyborg can run at its usual speed - the device will be stable for more than a month.

People learn the main thing about each other in just four minutes of conversation - even in a messenger.

These conclusions were reached by scientists from the University of Warwick during a study involving 338 people. They all played with partners in an online team game. Only one half of the volunteers were allowed to interact with each other prior to this, while the other half were not. The first group did better.
