Neolithic dairy farms

04.04.2003

Chemist Richard Evershed of the University of Bristol has used a new, highly sensitive mass spectrometer to examine the fragments of nearly a thousand pots unearthed from early man's settlements across Britain.

These fragments, ranging in age from 1500 to 6000 years, belong to the Neolithic, Bronze and Iron Ages. On some of them, including the most ancient ones, remains of milk fat were found. Thus, the earliest inhabitants of the British Isles ran dairy farms as early as 6000 years ago.

It is not clear in what form people then consumed milk. Many anthropologists believe that early man was intolerant of lactose, milk sugar. And in most modern peoples of Asia and Africa, milk causes intestinal upset. So, perhaps the ancient Britons curdled milk, making something like cheese or cottage cheese. Or maybe they waited until yogurt turns out.

Now chemists, in collaboration with archaeologists, intend to examine ceramics found in southeastern Europe, Turkey and the Middle East. There are suspicions that cattle were milked there a thousand years earlier.

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 ... >>

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, ... >>

100 Mbps for ISS 03.05.2020

A four-year-old project to create satellite systems for high-speed communication between space and ground stations is undergoing field testing. The equipment delivered earlier to the ISS made it possible to establish a downlink laser communication channel with a bandwidth of 100 Mbit/s with the ground station. The developer of technology and equipment was Sony.

Developed by Sony in collaboration with the Japan Aerospace Exploration Agency (JAXA) and the National Institute of Information and Communications Technology (NICT), the communication equipment is based on laser optical disc recording technology. Sony has a wealth of experience in this. By adapting data encoding mechanisms for writing to disk for transmission over an optical (laser) channel, the company was able to help develop the foundations of laser space communications.

Communication equipment was delivered to the ISS in September last year. Then it was mounted on an open Japanese Kibo module. Tests and equipment adjustments were carried out about once a week, when the weather allowed. For the first time, the SOLISS (small optical link for the International Space Station) downlink laser was installed on October 25, 2019. The first bi-directional link using a 1,5 µm laser was installed with a ground station on 5 March. The first HD images from the ISS were received via a laser Ethernet channel on March 11.

A series of experiments with equipment for laser communication will last until June 2020. It is assumed that communication via SOLISS channels will provide real-time transmission of large data arrays both between space stations, which will be required in further lunar and Martian missions, and between spacecraft and ground stations.
