Protein found to prevent preterm birth

01.01.2017

Researchers at Wayne University have found that the PIBF1 protein can prevent preterm birth. Scientists have planned to conduct trials involving women.

Scientists said that the PIBF1 protein is located in the uterus of a woman and affects her immunity. Previously, the scientific world did not suspect the existence of such cells. Scientists have planned to conduct studies that will allow them to better understand how using the substance can provide the best conditions for the course of pregnancy. In a recent study of PIBF1, 45 women were biopsied, some of whom gave birth prematurely. Using the samples, the scientists were able to recreate the protein and inject it into experimental rodents.

The study confirmed the effectiveness of the protein - thanks to the introduction of PIBF1, none of the laboratory rats gave birth prematurely. This discovery is primarily aimed at helping women who have been infected with a virus during pregnancy. Often, due to infectious diseases during pregnancy, the level of immune protection is reduced, which can provoke premature birth. Scientists note that prematurely born babies have a high risk of death. Those children whose mothers had a lack of PIBF1 protein were born not fully formed.

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 ... >>

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, ... >>

Flexible nano-thin touchscreen 20.01.2020

Touch screens of smartphones and displays have firmly entered our lives. It remains to make them even better - brighter, stronger, more flexible, more reliable and cheaper. Now scientists from Australia can suggest improvements on each of the points listed above.

A team of Australian scientists from the University of New South Wales, Monash University and the ARC Center of Excellence for Low Energy Electronics Technology (FLEET) published in the journal Nature Electronics the results of research in which they learned how to create the thinnest electrically conductive film, the properties of which allow it to serve as a touch screen. . It is alleged that the film is obtained almost atomic thickness.

Several layers of such a film can be used to create flexible touch screens for smartphones or displays, the transparency of which will be higher than traditional touchscreens made from modern indium-tin oxide (ITO) films. Conventional ITO touch screens absorb up to 10% of display backlight light. The 2D film proposed by scientists (which indicates the thickness of its layer) absorbs only 0,7% of light. Obviously, this transparency can be converted into a smartphone battery reserve, which will simply allow devices to work longer with a lower backlight brightness.

Even more useful, the production process of the ultra-thin touchscreen is very simple. As scientists joke, you can cook it yourself in your kitchen from the available ingredients. It is necessary to heat the alloy of tin and indium to 200 ° C, and as soon as they become liquid, roll the melt into a thin layer on a silicone mat. Seriously speaking, the proposed technical process involves the roll production of a thin film for the touchscreen using a method similar to printing newspapers in printing houses. It turns out much cheaper and without maintaining a vacuum, as required by the modern technical process for the production of "thick" touchscreens from ITO.

At the moment, scientists are trying to get a patent for their invention and are preparing to release prototypes of touchscreens of "nanometer" thickness. If they succeed, the technology could find applications not only in smartphones, but also in broad areas of optoelectronics, solar panels and smart indoor windows.
