Heavy-duty shell helmet material

11.06.2017

Mollusk shells are extremely durable shells that allow animals to withstand the "blows" of tides and storms, as well as fend off predators. Researchers from the Massachusetts Institute of Technology decided to study the structure of the shell of mollusks in more detail, and as a result they created a super-strong material that can be used in industry in the future.

A team of researchers developed 3D printing technology that allowed them to mimic the structure of a shell so they could study it more closely in the lab. They took the shells of molluscs of the strombid family as a basis. It turned out that they have a complex three-level structure with a zigzag matrix. Due to this, even if a small crack forms on the shell of the mollusk, it does not grow, as it has to "go through the labyrinth" of layers.

To better understand the formation of cracks in the shells, the researchers 3D-printed samples that resemble the shell of mollusks in structure and conducted a series of tests.

The results obtained during the tests showed that the structure of the shell prevents cracks by 85% better than most durable materials, such as those made of fiber composite.

The researchers believe their technology could be used to make helmets, protective clothing, and even self-defense gear.

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, ... >>

Gut bacteria can affect mood 19.02.2019

A study by Belgian scientists has shown that many intestinal bacteria can produce substances that affect nerve cell function and possibly mood.

Previously, several studies in mice have shown that gut microbes can influence animal behavior, and small human studies have shown that microbial composition in the gut changes with depression. To test the strength of the link between the human microbiome and mental health, Jeroen Raes, a microbiologist at KU Leuven (Belgium), and his colleagues studied a large group of people to assess a "normal" microbiome.

A total of 1054 Belgians participated in the study. Some of them - 173 people - were diagnosed with depression or scored poorly on quality of life tests. The team compared the state of the gut flora of participants with depression and the rest of the subjects. It turned out that in people with depression, the level of microbes such as Coprococcus and Dialister remained low in people's microbiomes. It didn't matter if people were taking antidepressants or not. Conversely, participants who claimed to have a high psychological quality of life had high levels of these microbes.

The team then looked at the medical test results of another group, which included 1064 Dutch people. The researchers found that the same two types of bacteria were absent from the microbiomes of those people who were depressed, as well as seven participants suffering from severe clinical depression. Scientists admit that the data do not currently support a causal relationship. Perhaps the effect even works the other way around: it’s not microbes that affect our mood, but our mental health affects the state of the microbiome.

However, in subsequent experiments, the researchers found evidence that microbes can communicate with our nervous system by producing neurotransmitters that are responsible for transmitting electrochemical impulses to nerve cells. Scientists have found, for example, that Coprococcus appears to have a pathway associated with dopamine, a key brain signal that is responsible for feelings of satisfaction.

The discovery could lead to new probiotic treatments for depression that could help increase levels of essential microbes in the human gut. However, many more studies need to be done to confirm that microbial compounds produced in the gut can affect our brain.
