Found a way to fight flesh-eating bacteria

24.09.2016

California scientists have made an important discovery about the bacteria that cause toxic shock syndrome, flesh damage and sore throat. New knowledge will help create an effective vaccine for all these diseases

Strains of group A streptococci differ in which proteins form the basis of their structure. They are called M-proteins, of which about 200 varieties are currently known.

"When we get a streptococcal infection, our immune response is usually against the M-protein that that strain has. So a specific immune response is directed against a specific protein," explains Parto Ghosh, co-author of the study at the University of California at San Francisco. Diego.

Because of this, the creation of universal drugs against streptococci was very difficult, because each time one would have to choose one of several hundred possible protein modifications for the "attack".

Despite this, it turned out that M-proteins still have some similar features. The study by Gosh and his colleagues, published Sept. 5 in the journal Nature Microbiology, clearly demonstrates that scientists have been able to identify common patterns in the structure of some proteins. These fragments are used to recombine the protein of human cells and use it to suppress the immune response. Now the team is working on a vaccine that would be able to recognize certain strains of streptococcal infections based on these patterns and effectively deal with them.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Global satellite map of the rainforest 24.10.2020

The Norwegian authorities implemented the project with the financial assistance of the International Climate and Forest Initiative (NICFI).

The NICFI initiative awarded a $44 million contract to Airbus, Planet and Kongsberg Satellite Services (KSAT) satellite surveillance systems to access their ever-changing data. And now this data, in particular those relating to the tropics of the planet, can be obtained absolutely free of charge by anyone. First of all, the map is addressed to those who are not indifferent to the fate of forests. The map data will be updated monthly.

Prior to the advent of the map, high-resolution images were not available in many parts of the world. And where they were available, not everyone could afford to use them.

The company's specialists have always believed that the results of observing changes on the planet should help people make smart decisions, said the CEO. And first of all - about the operational stop of deforestation, and not just the banal count of trees at the end of the year.

To create accurate images, Planet uses its Dove satellites. They fix 3,7-meter objects of the Earth.

Such detailed images will enable companies that buy cut areas of the tropics to be more prudent. At the same time, academia, journalists, conservationists and indigenous groups will be able to fight deforestation more effectively through the map. Including, bring to justice influential people who encourage him.

Much of the deforestation that the map shows is illegal. Now that there is a map, it is possible to influence the governments behind these illegal activities.
