The temperature of the world's oceans has been rising for four years in a row

21.01.2023

In 2022, the world's oceans reached their highest temperature on record for the fourth year in a row, according to new research. This is clear evidence of human-caused climate change.

Sea surface temperatures have a major impact on the world's weather, with warmer oceans associated with more extreme hurricanes, heatwaves, droughts and heavy rainfall.

Since 1970, the oceans have absorbed about 90% of the excess heat from greenhouse gas emissions. Ocean temperatures are less susceptible to short-term weather changes than air temperatures, making the oceans a good indicator of the effects of climate change.

A warmer ocean also means more water, rising sea levels and flooding. The oceans are rising, and more and more, the rise is accelerating.

The scientific work also studied the salinity of the ocean, which determines the density of water and affects the circulation of the ocean. The scientists found that the difference between average salinity in regions of high and low salinity (Salinity Contrast Index) was the highest of all time in 2022.

The study shows that the ocean is also becoming more stratified (layered), forming layers of varying densities, making it difficult to transport oxygen and nutrients through the water. Tighter stratification also causes the oceans to absorb less heat from the atmosphere, contributing to global warming.

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, ... >>

Internet for robots predicted explosive growth 08.10.2016

According to Research and Markets experts, the Internet of Robotic Things (IoRT) market will reach $2022 billion by 21,44 with a compound annual growth rate (CAGR) of 29,7% from 2016 to 2022 . The growth of the market, according to experts, will be driven by the entry of IoRT into the e-commerce business, as well as the expansion of the scope through the integration of robots with various technologies, short payback periods of projects and return on investment.

Experts note that the highest IoRT growth will be in the field of collaborative industrial robots working in contact with people - one of the most recent trends in industrial automation. Today, collaborative robots are used in various industrial segments, helping workers with welding, painting, sorting, and other tasks.

Besides, according to experts, in 2015 such segment of IoRT as house robots showed significant growth. "The prospect of the future is a kind of robotic butler who will serve people, helping them in their daily duties as a companion, freeing them from hard and monotonous work," Research and Markets explained. The ability of home robots to self-learning, the aging of the Earth's population and urbanization are noted as growth drivers for the segment.

Recall that earlier several large companies announced their own developments in the field of home artificial intelligence. For example, Facebook founder Mark Zuckerberg intends to create a robot assistant. According to Zuckerberg, it will be controlled by voice commands. He will help the head of Facebook manage home appliances, including music systems, lighting, and so on, and at work he will help Zuckerberg visualize the necessary data to run the company more efficiently. This year, Google's Deep Mind artificial intelligence actually made an intellectual revolution by beating a human at the game of Go for the first time, there are many other examples.

The home assistant will be more of a software solution than a mechanism or an android. According to an international study by Ericsson Connected Home, in Russia more than 50% of people would like to have an integrated solution at their disposal that could be controlled from a single device. There are already many different components on the market, but they are all controlled from different applications, and most importantly, they practically do not interact with each other. In such a situation, they will be of little use. First, you need to create a complete smart home ecosystem, where some components are connected to others. The next step will be the integration into this network of some kind of home artificial intelligence that can control all devices.
