Cocoa with flavonoids makes people smarter

18.10.2023

Increasing the consumption of flavonoids, which are part of cocoa beans, has a positive effect on human cognitive functions. American scientists came to this conclusion.

Cocoa beans contain many beneficial substances, including flavonoids. Studies have shown that increasing the concentration of these substances can speed up human thought processes even with high concentrations of carbon dioxide in the air.

Flavonoids are substances present in plants that play an important role in the human body. They have antioxidant activity, strengthen blood vessels, slow down blood clotting and improve the elasticity of red blood cells. Flavanols, a subgroup of flavonoids, are present in cocoa, grapes, apples, tea, berries and other foods. Although they are known to have beneficial effects on heart and vascular health, their effects on the brain require more research.

This scientific study was the first to confirm the link between flavonoid consumption and improved cognitive performance. As part of the work, scientists used a drink made from cocoa beans as a source of these compounds. However, the researchers note that the results also apply to other foods, such as fruits and green tea.

In the study, 18 healthy men aged 18 to 40 underwent a standard cerebral blood flow test. Under conditions of hypercapnia caused by inhaling air containing high levels of carbon dioxide, participants were given cognitive tests to assess brain activity.

The results showed that participants who consumed the flavanol-enriched drink had higher blood oxygen levels during hypercapnia. The concentration of oxygen in brain tissue increased three times compared to a regular drink. Also, after consuming cocoa with flavonoids, participants completed cognitive tests 11% faster.

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, ... >>

A new type of thermonuclear device has been developed 08.04.2024

Fusion energy continues to be one of the most promising areas in the field of energy, striving to create clean and efficient energy sources. Recent scientific developments, such as the new MUSE stellarator presented by scientists at the Princeton Plasma Physics Laboratory (PPPL) and the US Department of Energy (DOE), are breaking new ground in this field.

Scientists at the Princeton Plasma Physics Laboratory (PPPL) and the US Department of Energy (DOE) have unveiled a new type of stellarator, a special device for nuclear fusion reactions.

Stellarators, like tokamaks, use magnetic fields to confine plasma. However, in the new device, the magnetic fields have an unusual shape, exclusive to stellarators. They are toroidal, but also twisted along the axis of the plasma “cord”. A distinctive feature of MUSE is the use of permanent magnets, which distinguishes it from other devices where the magnetic field is created by electromagnets.

The MUSE device is assembled from standard components and equipment available in the commercial sector. Permanent magnets are integrated into a 3D printed shell surrounding a vacuum chamber containing the plasma.

In addition, MUSE has high quasi-symmetry, which contributes to the effective confinement of plasma inside the device and increases the likelihood of thermonuclear fusion reactions.

Future plans include a series of experiments to study in more detail the quasi-symmetry of MUSE and its effect on plasma confinement. These studies will include more precise measurements of magnetic fields and plasma rotation speed.

The development of the new MUSE stellarator represents a significant step in the development of fusion energy. Its advanced design and use of permanent magnets could lead to more efficient and sustainable plasma confinement, which is key to achieving fusion on a practical scale.
