Strength training reduces the risk of death

07.03.2022

Regular exercise that strengthens muscles reduces the risk of death from certain diseases, said Japanese scientists from the universities of Tohoku and Kyushu.

Muscle-strengthening exercises include weight lifting, push-ups, sit-ups, resistance band work, and even gardening. Experts analyzed 16 studies conducted in the United States, England, Scotland, Australia and Japan, which involved from 4 to 480 thousand people of different ages.

All studies have examined the effects of aerobic and strength exercise on the human body.

They found that 30-60 minutes of weekly exercise was associated with a 10-20 percent lower risk of death from cardiovascular disease, cancer, diabetes, and lung disease. The scientists noted that the results may not be completely accurate because the studies they studied were observational, not clinical, and were based on a subjective assessment of muscle strengthening activities.

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 ... >>

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, ... >>

Single-chip systems Qualcomm IPQ8074 and QCA6290 17.02.2017

Qualcomm introduced IPQ8074 and QCA6290 single-chip systems supporting Wi-Fi 802.11ax. The first is designed to serve as the basis for wireless network equipment, and the second is designed for client devices. According to the manufacturer, he is the first to offer such a kit.

Adopting 802.11ax can quadruple the capacity of Wi-Fi networks while extending the battery life of mobile devices. The new SoCs support 12-stream connectivity (eight streams in the 5GHz band and four in the 2,4GHz band), MU-MIMO configurations, 80MHz channels. Another feature is support for OFDMA (Orthogonal Frequency Division Multiple Access) modulation used in cellular networks and traffic scheduling.

The manufacturer notes that the full benefits of innovations are revealed in equipment that supports 802.11ax, however, devices of previous generations that support 802.11ac and 802.11n will work better in 802.11ax networks.

In the IPQ8074 description, the manufacturer highlights 8x8 MU-MIMO support and a high degree of integration. The single-chip system configuration includes an RF unit, MAC and signal processor, as well as a quad-core 64-bit ARM Cortex-A53 processor and a dual-core network accelerator. The microcircuit is designed for release according to the standards of 14 nm.

In turn, the QCA6290 supports 2x2 MU-MIMO and a peak speed of 1,8 Gb / s, which is achieved through the DBS (Dual Band Simultaneous) mechanism, which allows combining channels in the 2,4 and 5 GHz bands, and high-order modulation (1024 QAM). Another advantage is proprietary power optimization that complements the built-in 802.11ax power saving technologies.
