Which animals showed a positive effect after receiving a placebo?

The placebo effect affects not only people, but also animals. In a control group of epileptic dogs given pacifiers, seizures decreased in 79% of the participants. Scientists suggest that the improvement in the condition is due either to the expectation of the dogs themselves, accustomed to drugs for many years of illness, or the expectation of their owners, conveying to the animals confidence in the benefits of treatment. Also, a more prosaic explanation related to the cyclical nature of epilepsy cannot be ruled out: since the placebo may occur during the exacerbation phase, after some time the seizures become less due to natural causes.

Why is the Hatter from Alice in Wonderland insane?

In the days of Lewis Carroll, felt hat makers worked long hours with mercury vapor. Mercury poisoning often manifested itself in such symptoms as incoherent speech, memory loss, tremors, which was reflected in the saying "Mad as a hatter" ("Mad as a hatter"). That is why the Hatter from "Alice in Wonderland", aka the Hatter, is presented as insane.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

Good cholesterol protects against sepsis 01.04.2022

"Good cholesterol" refers to high-density lipoproteins, or HDL - large molecular complexes of lipids and proteins. The more of them, the less "bad cholesterol" in the blood, that is, low and very low density lipoproteins. "Bad cholesterol" increases the likelihood of atherosclerosis, "good" - reduces, in fact, that's why they are called that.

Lipoproteins carry lipids from place to place, from tissue to tissue, and as such they influence various physiological processes - not only lipid metabolism, but also, for example, immunity. Researchers at the University of Kentucky and the University of Michigan noticed that patients with sepsis generally have lower "good cholesterol" levels than healthy people, and the lower the level, the worse the clinical prognosis.

Sepsis, or blood poisoning, is an inflammatory response to a bacterial infection. Inflammation can be so severe that it will disable some organs and lead to death. Experiments with mice confirmed that HDL levels are associated with septic inflammation: animals that were known to be low in them were more likely to get sepsis when bacterial infection. It is likely that HDL somehow helps control the inflammatory response so that it does not turn into damage.

By increasing the level of "good cholesterol", you can cope with sepsis that has already begun. High-density lipoproteins have synthetic analogues that act in the same way as real HDL; clinical studies show that such analogues are quite effective in preventing cardiovascular diseases.

One of these analogs was injected into mice with sepsis, after which the inflammation in them subsided, the internal organs (for example, the kidneys) began to work better, and in general the mice were more likely to survive. It is possible that analogues of "good cholesterol" can be used in humans.
