Determining the level of air pollution in bee hives

13.03.2019

Scientists from the Pacific Center for Isotope and Geochemical Research at the University of British Columbia (Canada) analyzed beehives in Vancouver and found lead, zinc, copper and other heavy metals in them. This gave them the idea that honey is a good indicator of atmospheric pollution.

"Honey, which was obtained from beehives located in six blocks of Greater Vancouver, practically did not contain heavy metals and other harmful impurities, but if you analyze the honey collected in areas with heavy traffic, the picture changes very dramatically - in such honey you can find and lead-based compounds, and copper-zinc, and other hazardous substances," said Kate Smith, lead author of the study.

According to the researchers, they were very pleased with the results of the analysis. After all, the concentration of heavy metals and other toxins in the honey samples they took was significantly below the world average. And a person can harm his body only if he consumes more than 600 grams of such honey every day.

In addition to vehicle emissions, Vancouver's airborne lead source is the port. Cargo ships that enter it are also responsible for increasing lead levels in the city center.

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 ... >>

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, ... >>

Apple moves computers to its own processors 24.06.2020

Apple is developing a proprietary system-on-a-chip based on the common ARM architecture with a number of unique features specifically for the Mac. The first computer with the new platform will be presented before the end of the year.

As part of the WWDC 2020 conference, Apple officially announced the transfer of its computers to proprietary processors. CEO Tim Cook called it "a historic moment for the Mac platform." The company is reportedly developing its own system-on-a-chip based on a common ARM architecture with a number of unique features specifically for Mac.

The first computer with the new platform will be presented before the end of the year. The transition of the entire family of "apple" computers to processors of their own design will be carried out within two years. Apple promises that with this solution, Macs will be able to rise to new levels of performance and energy efficiency.

The most important difference between Apple's new ARM processors and Intel's solutions currently used by the company lies in native support for iOS and iPadOS applications, which will make the work of software developers easier and more efficient. Microsoft and other software vendors are already working on adapting their solutions to the new Apple processors.
