Mammoth Revival

13.09.2021

The American bioscience and genetic company Colossal decided to resurrect the woolly mammoth and has already managed to raise 15 million for its project. Ten thousand years after these giants disappeared from the face of the Earth, scientists decided to embark on an ambitious project to return them to the Arctic tundra.

As the authors of the project say, their goal is to create an elephant that is resistant to cold, but it will look and behave like a mammoth, that is, it will be functionally equivalent to a mammoth. These hybrid species are expected to thrive at -40°C.

To create an elephant-mammoth hybrid, geneticists will first need to sequence the woolly mammoth genome from a well-preserved specimen, such as one recovered from freezing in permafrost. By comparing the ancient genome with that of Asian elephants, parts of the DNA that code for the mammoth's adaptation to cold climates can be identified, such as hair, insulating layers of fat, and cold-tolerant blood.

This useful genetic material will then be added to Asian elephant stem cells created by modifying animal skin cells using the CRISPR-Cas9 gene editing tool and implanted into an Asian elephant egg. This egg will then be stimulated into an embryo and brought to term either by a surrogate mother elephant or, alternatively, in an artificial womb. The appearance of the first cubs can be expected in six years, the researchers say.

It should be noted that the practical aspects and ethics of reviving extinct species such as the woolly mammoth have been actively discussed for more than a decade. At the same time, even assuming that the creation of elephant-mammoth hybrids is possible, scientists express some skepticism that this would be the best way to restore the Arctic tundra.

Skeptics believe that this is not just a large-scale experiment, but also that it will take a long time, since future mammoths will take about 30 years to grow to maturity.

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, ... >>
