test tube beef

02.10.2019

It seems that the future has already arrived, at least in individual countries. Israeli startup Aleph Farms managed to grow beef in a test tube, for which you can not only rejoice. A steak made from animal meat produced in a laboratory without killing animals, first hit the table and was appreciated by gourmets.

The Israeli test tube steak created by Aleph Farms is a real food revolution. Prior to this, scientists presented artificial meat in 2013. It was minced meat from synthesized protein, from which a hamburger was prepared. A simple fast food dish with an innovative cutlet, given the costs of research and production, was estimated by experts at several hundred thousand dollars.

Of course, there was no talk of any mass production, and the unique food simply became proof that meat can be obtained without killing animals. True, the product created in 2013 could be called meat with a huge stretch.

An Israeli startup went the other way and abandoned protein synthesis. The stem cells of a calf are taken as the basis of their product, so the grown meat can be called real without exaggeration. This is no longer an abstract shapeless minced meat, but a full-fledged piece of beef, although small, but having density, texture, color, and most importantly, the taste of meat.

"Clean meat", which is what they call products derived from animal cells, is the goal of many companies. A firm that manages to commercialize the production of such meat will instantly make its owners billionaires. But so far, the production of muscle fibers in a laboratory is an expensive and, alas, thankless task that takes a lot of time. Even the startup Aleph Farms, which is ahead of the rest today, spent about 3 weeks making a very small steak.

By the way, what do you think happened to the first "clean meat" steak? Oddly enough, the same as with a regular steak - it was fried and eaten by the creators themselves. The honor of preparing the first cell meat dish in the history of mankind fell to Israeli chef Amir Ilan. The cook said that since the piece of meat was small, it took no more than a minute to cook.

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, ... >>

Created diffraction gratings for the world's most powerful laser 20.09.2022

Livermore National Laboratory researchers Lawrence (LLNL) and colleagues have designed and built new diffraction gratings for compressing high-energy laser pulses in the world's most powerful laser system. The new design will make it possible to transmit 10 PW of energy (1016 W) in one pulse. This is about ten times the total capacity of the US power grid, which is necessary for many areas of science.

Four HELD diffraction gratings (high energy low dispersion gratings) with dimensions of 85? 70 cm each will be installed in the ELI-Beamlines L4-ATON laser system in the Czech Republic. Such meter-sized HELD gratings could potentially contribute to the creation of future ultrafast laser systems with a power of 20 to 50 PW.

In a laser system, diffraction gratings are used to expand and then compress broadband laser pulses. The chirped pulse amplification (CPA) method was proposed in 1985 by physicists Gerard Albert Mourou and Donna Strickland, for which they received the Nobel Prize in Physics in 2018. Currently, the CPA method is the only one for obtaining a laser pulse of the petawatt level.

Thanks to the new diffraction gratings, the L4-ATON facility will be able to generate 1,5 kJ of energy in pulses with a duration of 150 fs (femtoseconds, 10-15 s), which will correspond to the transmission of an unprecedented power of 10 PW at a repetition rate of one pulse per minute. Achieving such energies will open the door to revolutionary research in areas such as plasma and high energy density physics, astrophysics, laser particle acceleration, advanced medical diagnostics, industrial processing technologies, and the detection of nuclear materials.

Compared to modern NIF ARC arrays, HELD arrays provide 3,4 times higher energy density. They are large enough, efficient and strong enough to withstand the high energy density of laser pulses. Stretching in time and spectral laser "shot" diffraction gratings reduce the energy load on the amplifying optical system, protecting it from damage. After amplification, the laser pulse is again compressed and thus reaches the highest energies without harm to the optical amplification channel.
