Yeast fungi will be sent into outer space

25.05.2019

The National Aeronautics and Space Administration (NASA) plans to send living organisms into deep space next year. NASA employees are working on a 14 kg BioSentinel spacecraft that will send two types of yeast cells into orbit around the Sun, one more resistant to radiation than the other.

BioSentinel and 12 other microsatellites are scheduled to be launched into orbit in mid-2020 by the Space Launch System (SLS) launch vehicle as part of the Artemis 1 research program as a payload. Scientific information from it, as expected, will be received over a period of 9-12 months. During the entire flight, scientists will monitor the reproduction of yeast fungi and at the same time monitor the condition of exactly the same samples located on the International Space Station, where the radiation level is much lower than in outer space.

In addition, the nuclear physics laboratory in Brookhaven, New York, will expose yeast samples to very high levels of radiation, Space.com reported.

"It is important that the process of DNA repair in yeast fungi is in many ways similar to the same processes in the human body," Space.com cited the opinion of NASA experts. "The results of research on BioSentinel will play a very important role in assessing the effects of radiation exposure on organisms."

The SLS will launch the Orion manned spacecraft, which is currently under development. It is planned that it will make its first flight without a crew using a new carrier in 2020: it will fly around the Moon and return to Earth. Among the microsatellites that are expected to be launched into orbit during the first launch of the launch vehicle are Lunar Flashlight and Lunar IceCube, designed to search for traces of water ice on the surface of the Moon, as well as a microsatellite with a solar sail, which will be directed to one of the converging with Earth asteroids.

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, ... >>

watermelon fuel 04.08.2020

Israeli scientists have presented a method for obtaining bioethanol from watermelons. The unique technology for making biofuel from watermelons reduces the dependence on fossil fuels, which still persists in the world.

For the production of biofuels, watermelons of a certain variety - Malay - are best suited. These fruits are grown for their seeds, but experiments have shown that their scope can be wider.

“The pulp and skin of these watermelons, which can make up to 97 percent of their weight, is usually thrown into the soil. But this is a very environmentally hazardous practice, as the organic matter serves as food for fungi and microorganisms that damage the soil and release greenhouse gases. ", - say the staff of the University of Haifa, who proposed a new use of Malay watermelons.

Experiments with dozens of watermelons showed that on their basis it is possible to establish an efficient production of bioethanol, which can be used as an alternative fuel. Plus, medicines can be made from bioethanol, for example, disinfectants, which are especially relevant during the coronavirus pandemic. In the future, as the authors of the new biofuel technology are sure, such solutions will significantly reduce the dependence of mankind on fossil fuels.
