Sharks are less likely to attack people

15.02.2019

In 2018, 66 unprovoked shark attacks on humans were recorded worldwide, the lowest since 2008, when 55 attacks were recorded. Another 34 attacks last year were human-instigated, nine shark attacks on boats, and one attack on a diver in a public aquarium.

In terms of geography, 32 of the 66 unprovoked attacks in 2018 took place off the coast of the United States (half of them in Florida), another 20 in Australia, three each in Brazil and Egypt, two in South Africa, one each in Bahamas, Galapagos Islands, Costa Rica, New Caledonia, New Zealand and Thailand.

More than half of the victims (53%) were involved in surfing and related sports during the attack, 11% were diving, and another 30% were just swimming. On average, over the past ten years, shark incidents have killed six people a year worldwide.

The Florida Museum of Natural History has kept shark attack statistics in the International Shark Attack File for over 60 years. Over time, the number of attacks continues to grow. So, until the end of the 1980s, the number of attacks in a decade never exceeded 300, and during the 2010s it already exceeded 700. The peak year was 2015, when sharks attacked people for no apparent reason 98 times.

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, ... >>
