What feature of cats' gait allows them to be more secretive?

The gait of cats and other felines is organized in such a way that they step with their hind legs almost exactly in the place where their front legs previously stepped. This reduces the noise from movement and the number of visible traces.

Why do we get tired?

Fatigue can be considered one of the types of poisoning! When the muscles of our body do some work, they produce lactic acid. If you remove lactic acid from a tired muscle, then we can immediately start working again! During muscle activity, the body also produces other substances known as fatigue toxin, or kenotoxin. The blood carries it throughout the body, and therefore the muscle itself, the whole body, and especially the brain, feel tired.

Scientists have conducted interesting experiments related to fatigue. If you force a dog to work until exhaustion, after which he falls asleep, and his blood is transfused into another dog, then the second dog will immediately feel tired and fall asleep too! If you pour the blood of a cheerful dog into a sleeping tired dog, then the latter will immediately wake up, not feeling tired anymore! But fatigue is not only a chemical process, it is also a biological process.

We cannot simply remove fatigue, we must give rest to the cells of the body. Losses must be restored, the nerve cells of the brain must be "recharged", and the joints of the limbs must restore the developed lubrication.

Sleep is also necessary to restore the energy of the body after it gets tired. In many cases, the best way to restore vigor in a tired body is by activating other parts of the body! Sometimes activity really helps to relax, because it enhances breathing. Blood begins to circulate faster, glands work more actively, and waste products are removed from tired parts of the body. But if you are completely exhausted, then it is best to sleep.

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, ... >>

Bees have emotions and mood swings 15.10.2016

Bees may experience something like happiness after receiving a treat that makes them feel more optimistic.

We usually think of emotions as internal awareness of a feeling, but there's a lot more to this subject, says Clint Perry of Queen Mary University in London. Physical changes and shifts in behavior accompany feelings of happiness and sadness.

To see if bees had similar patterns, Perry and colleagues trained 24 bees to associate certain locations and colors in the lab with cylinders of sugar or plain water. The scientists then closed the cylinders and gave half of the bees high-sugar water - the bee equivalent of chocolate - and measured the time it took for the insects to climb into the container with the hole. It was located between two closed cylinders and was painted in a medium color so that the bees would not know if there was sugar water in it or not.

The bees that received the sugar dose were quicker to get into the obscure medium feeder, as if they were more optimistic about the possibility that there was food there. And they didn't just act more actively because of the surge of energy. Both the bees that received a dose of sugar and the rest, with equal activity, climbed into the container, where there was definitely food, and with the same reluctance into the cylinder with plain water.

To see if a sugar cube could remove a negative experience, the researchers simulated a predator attack by carefully placing 35 insects in a trap that looked like a web of crab spiders. These spiders often prey on bees, but they can escape from them. Then the insects were released from the trap.

The bees given sugar flew to the feeder four times faster than those given nothing. It can be assumed that sweet food enhances positive emotions and helps to recover from negative ones - just like in humans.

After the bees were given a drug that blocks dopamine, which is responsible for the reward system in humans, all the effects of sugar virtually disappeared. This suggests that the bees behave according to their mood, Perry says.
