Trypillians ate almost no meat

06.01.2024

Research carried out by scientists from the Center for Collaborative Research (SFB) 1266 at the Christian Albrecht University in Kiel (CAU) reveals interesting aspects of the diet of Trypillian societies living in Europe around 6000 years ago.

An analysis of the Trypillian diet reveals unexpected aspects of their agricultural practices, emphasizing the importance of plant-animal interactions in providing adequate nutrition.

It was previously thought that these settlements in Moldova and Ukraine based their existence on subsistence agriculture. However, new research based on analysis of carbon and nitrogen isotopes in samples over the past 10 years has provided new data.

Dr. Frank Schlutz from Kiel stated: “The supply of food and pasture to large settlements required extremely complex management.”

The results of the study showed that the Trypillians, in addition to peas, which were the main source of food, used a small amount of livestock as fertilizer. Grain was also part of their diet, while meat consumption was practically nil. They used straw obtained from agricultural crops as animal feed.

This study highlights the importance of the relationship between crop and livestock production in the lives of Trypillian people, which allowed them to eat richly and healthily while reducing the labor and resource intensity of meat production.

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, ... >>

The driver will always notice the pedestrian 31.01.2014

Let's imagine a terrible but quite common situation: vehicles are moving along a residential area at low speed, but there are obstacles on the edge of the road - advertising poles, parked trailers, garbage cans, etc. - limit the view on both sides. Suddenly, because of such an obstacle, a pedestrian appears in the path of the car. In this case, the assistance system activates the brake system to stop the vehicle before it hits the pedestrian.

The braking system could have been activated because the pedestrian was equipped with a transponder, a combination of radio and transmitter that responds to certain signals, in this case, from the pedestrian identification system in the approaching vehicle. To determine the exact location of the pedestrian, the system measures the distance and direction of the person relative to the vehicle.

As part of the Ko-TAG research project, Erwin Biebl, a professor at the University of Munich, and his team have developed a new method for measuring distances that provides results with an accuracy of several centimeters within microseconds. To start the measurement process, the vehicle system transmits a unique code sequence. The transponder within range modifies the bit sequence and returns it within a precisely defined time interval.

Upon detection of an approaching pedestrian, the driver must be warned or the emergency braking system activated, even before the pedestrian has stepped onto the road. At the same time, the likelihood of hard braking without the need for drivers to recognize the system as reliable enough to use should be minimized. This requires a very precise motion estimation. In their study, the scientists were able to reduce deviations to a few picoseconds. "Thus, we achieved an accuracy of only a few centimeters in distance measurement," Beebl said. "Together with the coding method, this is the main reason for the high performance of the system."

The unique feature of the system is that it can identify other road users such as pedestrians and cyclists even if they are obstructed. In addition, this "interacting sensor system" can uniquely identify them and predict their behavior. Current driver assistance systems do not provide this.

"Transponders can be placed in clothing or in a school bag," suggests Beebl. They can also be introduced into mobile phones and smartphones - something that almost everyone carries with them at all times. This requires minimal hardware changes. According to scientists at the University of Munich, one of the major mobile phone manufacturers is already interested in the project.
