Safe time for coffee

03.11.2023

An international team of scientists has conducted a study that disproves the long-standing myth that coffee is bad for sleep. New scientific findings show that the drink has no negative impact on night's rest, even if consumed several hours before bed.

For many years it was believed that coffee could disrupt normal sleep and have negative effects on the nervous system, especially in the evening. However, recent studies show that a cup of coffee or tea drunk a few hours before bed does not harm the body.

Alcohol and nicotine, even in small doses, pose more serious threats to sleep quality. This follows from the results of a large-scale experiment that lasted 13,5 years. Participants recorded their feelings daily, indicating the number of cigarettes smoked, cups of coffee drunk, and alcohol consumed.

These results provide insight into the effects of coffee on the human body, although the researchers admit that they did not take into account the individual characteristics of each participant during the experiment.

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, ... >>

Smart ballpoint pen for handwriting digitization 01.05.2016

The French company Oree is known for its unusual products, such as the Oree Wooden Keyboard, a wooden wireless charger for smartphones with a built-in speaker system, and a wooden trackpad. This time, the Oree range has been replenished with a premium smart pen, which, in tandem with a special notepad, can not only write on paper, but also automatically duplicate, transferring data to a mobile device, everything “written with a pen”.

The body of the device, called the Stylograph, is made of copper, and visually it resembles a thickened ballpoint pen, which is based on ordinary ink. The elegant minimalist design and copper frame immediately hint at the rather high cost of the product, which, when using a branded notebook, will relay - digitize - your sketches, drawings and notes straight into the mobile application. The "chip" of the Oree Stylograph is the ability to preserve the tactile sensation of writing with ink on paper, while creating a copy of the handwritten material in electronic format.

As for the notebook, it is a notebook with 190 pages of A5 format, made in a traditional form factor. The accessory accessory costs $25, but the Stylograph turns out to be useless without it: the notepad uses mineral paper, on which the pen leaves barely noticeable traces. The principle of operation of the device implies that traces (prints) from a rod with a working surface of 0,7 mm will be recorded by a high-speed camera mounted in the handle. The built-in battery should last for two days of operation in moderate mode.

Data transfer from the smart pen is carried out via a Bluetooth connection with smartphones/tablets based on Android/iOS or Windows PC. The cost of new items is as much as $ 300, to which you will have to add $ 25 for a complete notebook. With this pricing, the only good thing is that the Stylograph uses a D1 type core, which can be easily replaced with a new one at any time.
