Benefits of Brewing

01.07.2022

It turned out that beer is not only a revered drink and a way to express one's political position, but also a potential support for the environment, namely, an inexpensive way to remove lead from water. This conclusion was made by specialists from the Center for Bits and Atoms at the Massachusetts Institute of Technology (MIT).

In particular, scientists have found that inactive yeast can be an effective and inexpensive way to remove lead from drinking water sources.

Studies have shown that 1 gram of this yeast can remove up to 12 milligrams of lead in less than 5 minutes.

What's more, because the yeast cells used in this process are inactive and dry, they don't require much care, unlike living biomass, which requires nutrients and sunlight to keep the materials active.

Scientists have calculated that the waste yeast thrown away from one brewery, for example, in Boston (USA), is enough to clean the entire water supply of the city (with a population of almost 700 thousand people as of 2020).

At the same time, such a solution would not only purify the water necessary for the needs of the city, but would also solve the issue of waste disposal from the brewery.

The researchers note that the yeast, similar to removing lead, could also absorb other heavy metals in the water, such as cadmium and copper.

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, ... >>

Prolonged stay in weightlessness inflates the brain 17.06.2023

Prolonged stay in space under conditions of weightlessness can cause the expansion of the ventricles of the brain, and their recovery to normal size takes about three years after returning to Earth. This interesting discovery was made by researchers at the University of Florida who were studying the effect of space travel on the brain structure of astronauts on the International Space Station (ISS).

Inside our brain are cavities called ventricles, and they are filled with cerebrospinal fluid. This fluid performs important functions by providing nutrition and protection to the nervous tissue, as well as removing metabolic waste. However, a long stay in a space environment with zero gravity leads to changes in this system. The ventricles of the brain adapt to weightlessness and begin to expand. When astronauts return to Earth, it takes a long time for these ventricles to regain their normal size.

The study was conducted on 30 astronauts, including different groups according to the duration of space flights. As a result of the study of astronauts who spent about two weeks on the ISS, it was found that the size of the ventricles remained practically unchanged. However, during semi-annual and annual missions, the size of the ventricles increased significantly. Interestingly, there were no noticeable differences between semi-annual and annual flight participants, indicating a slowdown in the process of ventricular expansion over time.

It was also found that previous space flight experience influenced the change in the size of the ventricles. The size of the brain ventricles of astronauts participating in repeat space missions less than three years later remained virtually unchanged. However, if the interval between missions exceeded three years (in the studied group from three to nine years), the ventricles again began to increase in size. Based on this, the scientists concluded that in about three years the brain cavities restore their normal size, corresponding to earthly conditions.

This discovery is important for future space missions and planning for astronauts in space. Understanding the changes that occur in the brain under weightless conditions will help develop effective methods for protecting the nervous system and maintaining the health of crews during long space flights.

This new scientific data allows us to gain a deeper understanding of how the space environment affects the human body, especially its nervous system and brain. This opens up new opportunities for research and development of methods for protecting and adapting the body to space conditions, in order to ensure the safety and success of future missions to the ISS and further space exploration.
