The cause of toxicosis in pregnant women has been found

27.12.2023

A group of international scientists from the UK, USA and Sri Lanka reveals the mystery of acute nausea and vomiting in expectant mothers. Researchers have revealed that the hormone GDF15, produced by the fetus, plays a key role in causing a condition known as hyperemesis.

About 70% of pregnant women experience these unpleasant symptoms, which sometimes become so intense that they make it difficult to eat and drink normally. Despite the prevalence of the problem, its roots have long remained a mystery.

Researchers have identified a genetic link between hyperemesis and the hormone GDF15, which produces fetuses. Professor Stephen O'Rahilly, from the University of Cambridge, suggests that future treatments will be based on blocking the hormone's access to receptors in the brain.

"This discovery makes us more confident that blocking GDF15's access to its receptors in the brain will provide the basis for effective and safe treatment of hyperemesis."

The revolutionary discovery was preceded by careful, multi-step work, including analysis of data from women participating in various studies, genetic studies, new methods for measuring hormones in the blood of pregnant women, and laboratory studies on cells and mice.

Identifying the role of the hormone GDF15 opens up the prospect of new treatments for hyperemesis in pregnancy, focusing on blocking the effects of this hormone on the mother's body.

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, ... >>

silicon foil 24.08.2008

Belgian scientists have made micron-thick silicon foil. To make foil from aluminum or other ductile metal, a piece of it is rolled many times in a special mill. You cannot do this with silicon, it is fragile. And foil from it would be very useful, because the thinner the substrate of a microcircuit or a solar battery, the less silicon consumption.

Scientists from the Interuniversity Center for Microelectronics, headquartered in the Belgian city of Levin, managed to make a foil from a single crystal of silicon. To do this, they applied a thin layer of metal to the surface of a thick silicon wafer, and then annealed it at a high temperature.

During subsequent cooling, thermal stresses arise due to the difference in the metal and silicon lattices. A crack forms in the silicon, which propagates parallel to the wafer surface. Eventually, the metal layer and the silicon layer adhering to it are separated. After removing the metal, a silicon foil is obtained with a thickness of 30–50 μm and an area of 25 cm2.

A solar battery, without any tricks created on such a foil, showed an efficiency of 10%. This indicates that high voltages did not spoil the silicon at all, and it is suitable for further work.
