Evidence built on sand

06.02.2006

The quartz sand database will soon be made available to Scotland Yard.

Employees at Oxford University studied under an electron microscope more than 40 samples of quartz soil grains from a thousand places in England and found that the entire variety of grains of sand can be divided into about 40 varieties. In the soil of each locality, these four dozen types of sand grains are found in a special ratio. If the same combination of grains of sand is found in two soil samples, the scientists say, it is very likely that the samples were taken from the same place.

Based on these data, a double murder committed in 2002 has already been investigated. The filter of the vacuum cleaner used to clean the interior of the suspect's car contained the same combination of quartz grains as where the bodies were found. And the same combination is contained in the dirt stuck to the bottom of the car.

In the future, scientists hope to expand the database and include soil samples, first from the continent of Europe, and then from other continents.

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, ... >>

Siemens A65: state employee with polyphony 25.07.2004

The division of Siemens for the production of equipment for mobile communication (Information Communication Mobile, ICM) introduced a new handset code number A65.

The mobile phone is positioned as inexpensive, simple and easy to use and, at the same time, a multifunctional device equipped with a 4-way navigation key. The screen of the new mobile phone supports 4096 colors.

An external camera with a flash is available as an optional accessory to the phone. Siemens A65 is the only budget A-class mobile phone that allows you to use the camera and send just taken pictures using MMS messages.

The developers also pay attention to the design of the keyboard - the numeric buttons are clearly separated from each other for the convenience of the user. The new mobile phone operates in three bands - GSM 900/1800/1900.
