turtle diver

08.07.2004

The leatherback sea turtle has set the diving depth record for a reptile.

This largest of all species of turtles can exceed two meters in length, the largest specimen found weighed 916 kilograms. It lives in all oceans except the Arctic. The species is listed in the Red Book.

English zoologists from the University of Wales, having placed depth gauges-recorders on the shells of several individuals, discovered that one of the experimental turtles dived in the Atlantic, away from the coast, to a depth of 640 meters. Unpublished data suggest that turtles of this species are able to dive a kilometer.

Leatherback turtles feed on jellyfish and other gelatinous plankton, and since this food is about 98 percent water, they have to work hard to find food. The previous record, recorded close to the coast, was 475 meters.

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, ... >>

Nanohousing for sun-loving bacteria 10.03.2022

Researchers at the University of Cambridge in the UK have 3D printed a grid of high-rise "nano-housing" in which sun-loving bacteria can grow rapidly. With these "houses," scientists have been able to extract more of the energy generated from photosynthesis from bacteria, which can be used to power small electronics - more than with traditional renewable bioenergy production methods.

Cyanobacteria are large bacteria capable of photosynthesis. For several years, researchers have been trying to "reconfigure" the mechanisms of photosynthesis in cyanobacteria in order to extract energy from them. To grow, cyanobacteria need a lot of sunlight - for this they are well suited, for example, the surface of a lake in summer. And in order to extract the energy they produce from photosynthesis, bacteria must be attached to electrodes.

A team from Cambridge has 3D printed special electrodes from metal oxide nanoparticles - highly branched, densely packed columnar structures, similar to a tiny city. Scientists have developed a printing method that allows you to control the different lengths of the bars.

The new method increased the amount of extracted energy by an order of magnitude compared to other methods of producing bioenergy from photosynthesis.

"Cyanobacteria are versatile chemical factories. Our approach allows us to use their energy conversion pathways at an early stage, which helps us understand how they perform energy conversion so that we can use their natural pathways for renewable fuels or chemical production," the authors note. work.
