Why do male chimpanzees prefer older females to younger ones?

Observations of chimpanzees in the national park of Uganda have shown that males of these primates prefer to mate with old females, and only the weakest males pay attention to young ones. After all, the older the female, the more offspring she has already raised, and new cubs from her will survive and develop successfully with a greater probability.

What is the Industrial Revolution?

Man has been living on Earth for a very, very long time. But throughout its long history, the biggest changes in daily life have only occurred in the last 200 years! These changes in lifestyle and work are based on the improvement of machines. This significant period is called the "industrial revolution".

Since its inception, man has been constantly creating tools. Then came the machines. It wasn't until 1750 that a real machine was invented. A machine is also a tool of labor, but it does almost all the work, frees a person from energy costs. This transition from tools to mechanized machines was so important, so significant, that it affected every aspect of life. This example shows how one invention leads to another.

To get the most out of machines, new energy sources had to be found. Before the industrial revolution, only the power of human muscles, animals, the power of wind and water was used. To use the machines that man invented, a new source was discovered - steam. This allowed factories to be built. They were close to raw materials and the market. With the further development of machine tools and mechanisms, more and more iron and steel were required. And so there was a need for new methods of mining.

Machines could produce more goods that needed to be sold. So, it was necessary to improve their transportation to the market. This led to the need for better roads, the construction of canals, the development of rail transport, and the construction of large ships and steamships to transport the created goods to distant markets.

Man began to deal with markets around the world, the role of communications increased. The telephone and telegraph were invented. But more changes were needed. Factories grew, they used large and expensive machines, and a person could no longer work at home. He began to do this in factories and plants. This led to a division of labor, a man in a factory performing only one operation throughout the day, while at home he was forced to produce a product completely.

After all, the industrial revolution made it possible to produce simple and cheap products available to everyone.

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, ... >>

Heat controlled microbe 25.04.2012

Scientists at the University of Georgia have created a temperature-controlled microbe. The new microorganism could be an efficient means of producing complex chemicals from simple starting materials.

Initially, scientists took the microbe Pyrococcus furiosus, which lives in hot marine sediments and actively reproduces at temperatures around 100 degrees Celsius. This microorganism is an archaea, a single-celled prokaryote that is similar to a bacterium, but has significant differences at the molecular level and is able to perform processes that bacteria cannot.

Nowadays, many manufacturing processes depend on microorganisms. However, the production activity of bacteria is very difficult to control, especially to switch them from one activity to another.

American scientists have found a way to control heat-loving microbes using a temperature switch. Simply put, at high temperatures, the microbe produces one product, and at low temperatures, another or not at all. This greatly simplifies the use of microorganisms as miniature plants for the production of useful substances such as biofuels. Also, for the first time, scientists have managed to make changes to the genome of a hyperthermophilic bacterium, which opens up new opportunities in the creation of genetically modified microorganisms with unique functions.

Like other hyperthermophilic bacteria, Pyrococcus furiosus can function at high temperatures, which is very useful in many industrial processes in the chemical industry. However, not all substances can be produced under such conditions - some enzymes can only work at low temperatures.

To solve this problem, scientists took a specific gene from the bacterium Caldicellulosiruptor bescii, which lives in cooler conditions (72 degrees Celsius), and placed it in the genome of Pyrococcus furiosus. As a result, at high temperatures, Pyrococcus furiosus functions as usual, and when the temperature drops, it begins to produce another, unusual product, lactate dehydrogenase.
