The unscientific diet of centenarians

06.01.2017

American scientists told what kind of food centenarians prefer. It turned out that their dietary habits do not coincide with the advice of nutritionists.

Experts have found that residents of the so-called "blue zones" or places on the planet with the highest life expectancy do not always follow the advice of doctors. Many of them eat meat, eggs, drink coffee and even whiskey.

For example, Emma Morano, who is already 117 years old, has been eating raw eggs every morning since the age of twenty, and the diet of the Japanese Miso Okawa, born in 1898, regularly contains ramen noodles, beef and sushi. American Susanna Mushatt Jones, who lived to be 116 years old and died in 2016, regularly ate bacon and eggs during her lifetime.

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 class of metamaterials capable of changing their physical properties 18.12.2018

Modern metamaterials are very similar to the technologies we know from science fiction. Due to the unique properties of such materials, it is possible to create incredible things, invisibility cloaks that hide objects in various wavelengths of the electromagnetic spectrum, and in practice, such technologies are already used in mobile phone antennas, for example. Note that all metamaterials, which we have talked about more than once on the pages of our site, have a set of fixed properties, albeit unique, which significantly limits their scope.

Researchers at the Lawrence Livermore National Laboratory (LLNL) and the University of California San Diego have developed a new class of metamaterials, mechanical metamaterials that can become rigid or flexible in response to an external magnetic field.

To create a new miracle metamaterial, the researchers used the so-called 4D printing technology. This technology got its name from the fact that objects made using three-dimensional printing can change their shape over time, which acts as the fourth dimension. As a rule, changes in the shape of an object occur under the influence of some external factor - high temperature, hydration, exposure to a magnetic or electric field.

The new technology is based on materials capable of responding to external fields (FRMM, field-responsive metamaterial). However, unlike the materials used in other 4D printing technologies, FRMM materials do not change their shape, the changes affect some of their physical properties, hardness, in this case. The creation of FRMM materials turned out to be quite simple - instead of a monolithic structure of the printed object, a tubular hollow structure is formed. And these cavities at the next stage are filled with a special magnetic fluid.

A ferrofluid consists of tiny particles of a magnetic material uniformly dispersed in a volume of a non-magnetic solvent. When such a liquid is exposed to an external magnetic field, the particles in its volume become ordered, aligning themselves along the lines of the magnetic field, and the material turns into a practically solid monolith. In the absence of a magnetic field, the ferrofluid behaves like an ordinary viscous fluid, capable of flowing freely in any direction.
