World's oldest cheese discovered

24.08.2018

The tomb of Ptahmes - a dignitary at Memphis in Egypt in the 13th century BC - was originally discovered in 1885. After being lost under the drifting sands, it was rediscovered in 2010. A few years later, archaeologists discovered several jars in it. One jar contained a hardened whitish mass and a web of cloth that could cover the jar or be used to contain its contents. Enrico Greco and his colleagues set out to analyze the whitish substance to identify it.

After dissolving the sample, the researchers isolated its protein constituents and analyzed them using liquid chromatography and mass spectrometry. The peptides detected by these methods indicate that the sample is a dairy product derived from cow's milk with the addition of sheep's or goat's. Characteristics of a fabric that indicate that it is suitable for holding a solid rather than a liquid.

The absence of other specific markers supports the conclusion that the dairy product was a hard cheese. Other peptides in the food sample suggest it was contaminated with Brucella melitensis, the bacterium that causes brucellosis. This potentially fatal disease is transmitted from animals to humans, usually through unpasteurized dairy products.

If the team's preliminary analysis is confirmed, the sample would represent the earliest evidence of a biomolecular disease.

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 ... >>

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, ... >>
