Similarities between tyrannosaurus rex and chicken

03.11.2007

The remnants of collagen found in the bones of a tyrannosaurus rex found last year were analyzed at the University of North Carolina (USA).

Collagen is a very strong and stable connective tissue protein that holds together the mineral elements of any bone. When comparing the amino acid composition of collagen aged 68 million years with the same protein of modern animals, it turned out that according to this indicator, the greatest coincidences exist with chicken collagen - almost 60%.

The find confirms the theory of the evolutionary relationship of dinosaurs and birds.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Film and the composition of the air of the auditorium 26.05.2016

Scientists analyzed air samples from cinema halls that showed films of various genres, and found that the emotional state of the audience can be determined by the composition of the gases exhaled by it.

Feedback also works: you can determine the film by the dynamics of the composition of the atmosphere in the cinema. Scary and funny scenes are best defined, say chemists from the Max Planck Institute for Chemistry and the Gutenberg University of Mainz.

While watching The Hunger Games, according to Jonathan Williams, head of the research team at the Max Planck Institute for Chemistry, the levels of carbon dioxide and isoprene in the air rose sharply as soon as the heroine began to fight for her life on the screen.

A healthy person exhales carbon dioxide mixed with small amounts of other gases - their number reaches 800. The physiological processes that determine the synthesis and release of these substances have not yet been fully studied.

Initially, researchers dealt with the issue of gases exhaled by humans and their impact on the composition of the planet's atmosphere and the greenhouse effect. The study of the atmosphere over the football stadium during the match did not give interesting results - perhaps because the match ended with a score of 0 - 0. Then the scientists came up with the idea to analyze the air in rooms where people experience strong emotions - for example, in the cinema.
