Mongoose robot walking through a minefield

11.11.2008

Employees of the University of Sri Lanka propose to use a mongoose connected by a leash to a sapper robot to search for anti-personnel mines.

The mongoose, with its keen sense of smell, can be trained to detect the smell of explosives, and the robot, made in the form of a disk on wheels, contains a conventional mine detector that reacts to the presence of metal parts in the soil. In addition, the robot carries a miniature video camera aimed at the mongoose.

The operator sitting to the side sees the reaction of the animal to the smell on the monitor and hears the signals of the mine detector. Since the total weight of the team is small, the mines under it do not explode.

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, ... >>

Harsh winters coming due to global warming 20.06.2012

Last winter in mid-January, a severe cold snap hit Central and Eastern Europe - the temperature dropped to -30 degrees Celsius, and snowdrifts rose to the roofs of houses. Residents of several eastern US cities, such as Washington, New York and Philadelphia, have experienced similar weather "adventures" over the past two years.

Scientists from the Earth and Atmospheric Science Laboratory at Cornell University believe that such phenomena will occur more often in the future. In their opinion, this is due to the abrupt melting of Arctic sea ice, which will lead to much more serious and rapid climate change than most non-specialists realize.

Melting Arctic sea ice could cause a domino effect that would dramatically increase the likelihood of severe winters in the mid-latitudes of the Northern Hemisphere. Global warming increases the melting of sea ice in the summer, opening up dark ocean waters to sunlight. This leads to greater absorption of solar radiation and excessive heating of the ocean in summer. Excess heat is released into the atmosphere mainly in autumn, reducing the temperature and atmospheric pressure gradient between the Arctic Ocean and mid-latitudes. This allows cold polar air to penetrate unhindered into lower latitudes and cause severe frosts and heavy snowfalls in Europe and the United States.

Increasing climate instability leads to unpredictable anomalies: in some parts of the Northern Hemisphere, winters can be record warm, while in others - with severe frosts and snowfalls. And the last with each decade will be more and more.
