White sharks make animals stressed

11.12.2017

A scientific group from the University of Montana began to study how the neighborhood in the underwater world affects the psychological state of the inhabitants there. They were able to establish that white sharks are the main source of stress for many marine animals.

The study went on for several years. Experts observed how the life of fur seals from different colonies living in the waters of South Africa goes. It was possible to establish that the animals experience the greatest danger precisely when white sharks appear nearby. It was at these moments that the levels of the stress hormone cortisol in animals increased significantly.
The analyzes were carried out when the seals were in different conditions.

Stress, at its core, scientists explain, is a protective reaction of the body and often saves from serious consequences.

In the case of fur seals, it causes serious illness and can even lead to the death of an individual, as it has disastrous consequences for the heart.

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, ... >>

Video in breast pocket 05.06.2002

The Japanese company "Sony" has started production of a subminiature digital video camera DCR-IP5. Dimensions are clear from the photo, weight - 310 grams. The lens is equipped with a tenfold optical zoom, there is also a 12x digital zoom.

A cassette smaller than a matchbox holds an hour of high-quality video (over 500 vertical lines). True, due to the small size of the device, the charge of the standard battery is only enough for 35 minutes of shooting. This means that the entire cassette cannot be removed from one charge. When recording, the MPEG-2 video information compression method developed for computers is used.

Only every 12th frame and information about where and how its individual elements move is recorded on film. When played back, the full picture is restored from this information.
