Antioxidant reduces the risk of recurrent heart attack and stroke

12.09.2018

Scientists from the University of Oregon have developed a new way to reduce the risk of a secondary heart attack or stroke.

Heart attacks in mice caused inflammatory cells and platelets to easily adhere to the inner lining of arteries throughout the body - and especially where there was plaque. As a result, blood clots formed, which led to a new heart attack or stroke.

It turns out that treating mice with a heart attack or stroke with the powerful antioxidant apocynin cuts plaque formation in half and reduces inflammation in the body to levels that precede the first attack.

The researchers detected sticky cells and platelets using a unique form of ultrasound imaging they developed to look at molecules on the inside of blood vessels.

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, ... >>

New properties of black holes 25.09.2018

A UC Berkeley mathematician has shown that Albert Einstein's equations of relativity suggest that inside some black holes, the past of a conventional observer is erased and various futures appear. This refutes one of the fundamental cosmological theories - the theory of "cosmic censorship".

The scientist’s calculations show that in the case of some types of black holes in an expanding universe like ours, an observer could survive a transition beyond the event horizon from a deterministic world to an indeterministic one, where his past would be erased and his future became uncertain.

What life would be like in a space where the past has disappeared and the future has an infinite number of options is unclear. But Hintz's conclusion doesn't mean that Einstein's equations of general relativity, which still perfectly describe the evolution of the universe, are wrong, says the author of the discovery.

“As far as I know, no physicist is going to travel inside a black hole and measure what is happening in it. This is a purely mathematical problem, and the solution I proposed makes the Einstein equations mathematically more interesting,” Hintz says. “This is a question that can really be studied mathematically , but the answer to it has physical, almost philosophical implications, which makes solving the riddle of erasing the past beyond the event horizon a very cool thing to do."
