Effect of water temperature on civil unrest

19.07.2012

Statisticians from Princeton University (USA) analyzed 234 episodes of civil unrest and unrest that took place from 1950 to 2004 in 175 countries of the world, and found that in 90 countries experiencing the influence of El Niño, the likelihood of conflicts during the years of this oceanic phenomenon was twice as high as in countries far from the equatorial part of the Pacific Ocean.

El Niño is an intermittent warming of the upper layers of water off the coast of Peru, lasting more than a year. It affects the climate mainly in South America, where floods or droughts can occur during El Niño years. The weather affects mainly those countries where the entire economy is tied to agriculture and unrest can arise in case of crop failure. In the twentieth century, especially powerful El Niño events occurred in 1925-1926, 1982-1983 and 1997-1998.

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, ... >>

Canon PowerShot V10 flip camera for vlogging 11.05.2023

Canon has announced the PowerShot V10 flip camcorder, designed for bloggers and those who often shoot in conditions where a large camera is inconvenient to use and a smartphone is not enough.

This is a compact and lightweight camera that fits easily into your pocket. It is equipped with a tilting retractable stand, which is attached to the body, which allows you to shoot on it without a tripod, and in several positions.

You can follow the recording on a small 2-inch screen that can be rotated 360 degrees. There are recording control buttons below the display.

The camera uses Canon's DIGIC X technology for image processing, and EOS for high-quality low-light movie recording. The maximum ISO for shooting in 4K is 3200 and for 1080p is 6400. The maximum shutter speed for shooting is 1/2000 and for video it is 1/4000.

Sound recording is provided by a microphone equipped with noise absorption. Of the image enhancement technologies in the camera, there is skin smoothing, face recognition autofocus, and others. Among the shortcomings of the model, there is a lack of eye recognition and shooting in 4K.

The PowerShot V10 is charged using the USB-C connector. One charge is enough to record 1 hour of 4K video. This is enough for live streaming on YouTube, which can be done using the Canon Connect program and connecting to a smartphone. When connected to a computer, the device can be used as a webcam.

The cost of new items is $429.
