Corals push Japan's borders

11.12.2007

The rocky islets of Okinotori, lying 1700 kilometers south of Tokyo, allow Japan to retain a XNUMX-mile economic zone in the area.

Within 200 nautical miles from the extreme point of its land, any coastal country has the right to conduct economic activities. But rising ocean levels due to global warming may soon hide these patches of land under the waves, and then the entire area will become the possession of China.

To avoid such an unpleasant prospect, the Japanese recently "sowed" the shores of the Okinotori islands with coral larvae. When the corals grow, they form a reef that will remain in place of the islands, even if these rocks themselves sink.

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, ... >>

Ultrasonic tweezers move living cells 13.07.2012

Bioengineers and biochemists at the University of Pennsylvania have developed a miniature ultrasound device capable of capturing and moving single cells and tiny living organisms. The coin-sized device can be used to work with live samples such as blood cells or bacteria. Using a new device called acoustic tweezers, scientists have already been able to manipulate roundworm (Caenorhabditis elegans) 1 mm long. This organism is an important model for the study of several human diseases.

Acoustic tweezers are also capable of manipulating living cells, which are essential to many areas of basic biomedical science. The device is based on the use of a piezoelectric material that vibrates under electrical voltage. Vibrations induce surface acoustic waves in the liquid medium around the cell culture. With simple electronics, acoustic waves can be manipulated and organic and inorganic materials can be moved.

The main advantage of acoustic tweezers is their harmlessness to living cells. Currently, scientists use lasers to manipulate such samples. However, they consume 10 million times more energy and can heat up and damage cells.

Acoustic tweezers turned out to be very versatile: with its help, you can control both one particle and tens of thousands. For example, ultrasonic tweezers can place drugs directly on a bacterium and at the same time exert pressure on its cell wall. It can also be used to sort blood cells and cancer cells.

Currently, the size of objects that can be moved with acoustic tweezers ranges from micrometers to millimeters. The developers note that when using higher frequencies, it will be possible to move nano-sized objects.
