Russia is developing technologies that rely on artificial intelligence to monitor phenomena that affect the climate

According to the available information, "Russian scientists were able to develop software that relies on artificial intelligence to monitor the El Niño and La Niña phenomena that affect climate change on Earth throughout the year. Experts from the Russian company Yandex contributed to the aforementioned project to use the Yandex.Cloud electronic cloud to document data."

On the subject, Russian environmental safety expert, Dmitry Vetrov, said: "The two phenomena affect the climate of the Pacific Ocean and the entire planet, causing heavy rains in some places and droughts in others, so predicting them is important in light of the increasing climate change on our planet."

The available information indicates that Russian scientists and Yandex experts provided their new digital algorithms with information on thousands of heat maps related to the planet that were created since the nineteenth century, and tested the capabilities of new technologies for data processing and analysis, and these techniques showed excellent results in data analysis.

Musk accuses Microsoft of illegally using Twitter data during the creation of artificial intelligence

American billionaire Elon Musk has accused Microsoft of illegally using data from Twitter to train the company's artificial intelligence model.

"Microsoft illegally trained [artificial intelligence] using Twitter data. It's time for a judicial investigation," Musk wrote on his Twitter page on Wednesday.

On March 22, more than 1,000 AI experts, including Musk, published an open letter calling for a temporary halt to training systems more powerful than GPT-4 for at least six months because the uncontrolled process in this field could pose a threat to humanity. But Microsoft founder Bill Gates opposed such a halt.

It is noteworthy that the ChatGPT chatbot was launched from the American company OpenAI at the end of November 2022. The service interacts with the user in dialogue mode.

An AI based on the GPT-3.5 language model can answer additional questions, admit its errors, argue for incorrect premises, and reject irrelevant requests.

The possibilities of this service attracted great and wide public interest all over the world, including in Russia. Source: TASS

New wound dressings detect infection in real time without interfering with the healing process

Researchers at Linköping University in Sweden have developed a nanocellulose wound dressing that can detect early signs of infection without interfering with the healing process.

The study, published in Materials Today Bio, is another step on the road to a new type of wound care.

The skin is the largest organ in the human body. The wound disrupts the normal function of the skin and can take a long time to heal, be very painful for the patient and, in the worst case, may lead to death if not treated properly.

Wounds that are difficult to heal are also a significant burden on society, and account for about half of all outpatient care costs.

In traditional wound care, the dressings are changed regularly, about every two days. To check if the wound is infected, the care staff must lift the dressing and make an assessment based on appearance and tests. This is a painful procedure that hinders wound healing as the scabs frequently break. The risk of infection also increases each time a wound is exposed.

Researchers at Linköping University, in collaboration with colleagues from Orebro and Lulea Universities, have developed a wound dressing made of nanocellulose that can detect early signs of infection without interfering with the healing process.

“Being able to tell immediately if a wound has been infected, without having to lift the bandage, opens up a new type of wound care that could lead to more efficient care and improved lives,” says Daniel Ailey, a professor in the Department of Biophysics and Bioengineering at Linköping University. "Patients with wounds that are difficult to heal. It can also reduce the unnecessary use of antibiotics."

The bandage is made of tightly meshed nano-cellulose, which prevents bacteria and other microbes from entering. At the same time, the material allows the passage of gases and liquid, which is important for wound healing. The idea is that once the bandage is applied, it will stay on throughout the healing process. If the wound becomes infected, the dressing will show a change in color.

The pH value (pH) of uninfected wounds is about 5.5 pH. When infection occurs, the wound becomes increasingly radical and may have a pH value of 8 or higher. This is because the bacteria in the wound change their surroundings to suit their optimal growth environment.

A high pH value can be detected in a wound long before any pus, soreness or redness appears, which are the most common signs of infection.

To make the wound dressing show a higher pH value, the researchers used bromethymol blue, BTB, which is a dye that changes color from yellow to blue when the pH value exceeds 7.

To use the BTB in the dressing without compromising it, it was loaded onto a silica material with pores only a few nanometers in size.

The silica material can then be combined with the dressing material without compromising the nano-cellulose material. The result is a wound dressing that turns blue when an infection is present.

Wound infections are often treated with antibiotics that circulate throughout the body. But if the infection is caught at an early stage, topical treatment of the wound may be sufficient. This is why Aile and his colleagues at Orebro University are also developing antimicrobial substances based on so-called lipid peptides that kill all kinds of bacteria.

Ailey says the new wound dressing and antimicrobial material are part of developing a new type of wound treatment in patient care. But because all products to be used in medical care settings must pass rigorous and expensive testing, he believes it will take five to 10 years before they become available. Source: phys.org

Russia is developing a combat drone that takes off from the hand of the person operating it

Russian startup Military Innovators has developed a fighter drone that can be launched without a catapult in two minutes.

This was reported by the Russian agency "Tass", quoting a source in the company.

The engineers explained that the take-off of the regular drones in the form of an aircraft such as "Orlan" or "Illeron" requires a catapult to be launched from, and the process of deploying the catapult and launching the march later from it takes a period ranging between 15 and 20 minutes. However, in combat conditions, the price of every superfluous minute is assessed by the life of a soldier, because enemy artillery can target the personnel operating the drones.

With regard to the "Oqab" drone, its assembly process is very simple and takes only two minutes, allowing the drone to take off and land without endangering the life of its operator.

The company's engineers said that the take-off of the march, which has a wingspan of two meters, can be verified by the hand of the person operating it or from the ground directly because the "Oqab" takes off vertically as a helicopter, then turns on the front propeller and flies as if it were a regular plane.

The march takes about two hours to fly, with a speed of 70 km/h, a maximum range of 170 km, and a flight height of 3 km.

The company's engineers intend to test their vehicle in the special military operation area.

It is noteworthy that the "Military Innovators" company develops many military devices, including acoustic radars that are used in artillery weapons. Source: Rossiyskaya Gazeta
