11.02.2019

The new STEVAL-SMARTAG1 demo board from ST Microelectronics allows you to monitor a variety of environmental parameters and transfer measurement results to a smartphone using NFC wireless technology. With the help of MEMS sensors on board, STEVAL-SMARTAG1 allows you to control temperature, atmospheric pressure, humidity, tilt and acceleration angles. The miniature board contains a low-power STM32L031K6 microcontroller, a LIS2DW12 low-noise accelerometer, an LPS22HB digital barometer, and an HTS221 temperature and relative humidity sensor. The device is powered by a miniature disk element CR2032 (not included) or by the energy of the RFID reader field, which can be any smartphone (Android or iOS) with NFC support.

STEVAL-SMARTAG1 can act as the basis for developing your own application - the board has a connector for connecting to the SWD ST-Link/V2 programmer. The downloaded application is available as full source code.

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, ... >>

Love for coffee is genetic 26.08.2016

Researchers at the University of Edinburgh in the UK found that people with a DNA mutation in the PDSS2 gene tend to drink less coffee than those without the mutation. According to scientists, this is due to the fact that the mutated gene slows down the processing of caffeine by the body and maintains the effect of coffee for a longer period.

Scientists studied the genetic makeup of 370 people living in a small village in southern Italy and compared it with the DNA of 843 people from villages in the country's northeast. In addition to this, each of them was asked how much coffee they drink every day.

It turned out that people with mutated PDSS2 drank on average one cup of coffee less than the rest. The same experiment, conducted with 1731 people in the Netherlands, gave the same result, only the difference in consumption was slightly smaller. Scientists explained this gap by different portions of coffee that are accepted in each of the countries: in Italy these are small cups, in the Netherlands they are large, with a higher content of caffeine.

"The study confirms the idea that genetics play a very important role in our daily habits and lifestyle, and understanding this will help us not only understand how people behave, but also why they do it," the scientists said.

In a larger study conducted in 2014, scientists examined the DNA of more than 120000 people and found that mutated genes help people adjust the amount of coffee they drink based on how efficiently their bodies are able to metabolize caffeine - for optimal coffee effects.
