How can plants help mine clearing?

For demining territories without human intervention, specially trained animals have long been involved - bees, rats, mongooses, as well as sea lions and dolphins, when it comes to clearing sea mines. However, plants can also help in clearing mines, for example, a flower called Tal's resicum. This plant is known for turning red in harsh environments, and its genetically engineered version turns red in the presence of nitric oxide, which evaporates from explosives. Thus, after spraying seeds over minefields and waiting for the seedling of this plant, it is possible to clearly determine in which places the mines are located.

When did the bath appear?

In ancient times, people bathed for two reasons: to maintain cleanliness and to observe religious rites. The ancient Greeks and Romans loved to take a bath for relaxation and pleasure. Washing places became social centers, and bathing was also considered a way to cure diseases. Among the ancient Egyptians, it was mainly a religious ritual. The Jews, like the Hindus, believed in bathing as a religious rite.

The very first baths known to man are the palace baths on the island of Crete. They are about 4000 years old. The palace housed bathrooms with foot baths and tubs. A bathtub was found in the royal chambers of the palace, which dates back to 1700-1400 BC. It looks like a modern one. In fact, since a person had a desire to use baths, its design has not changed throughout history.

Even in ancient times, the Greeks washed in the bath. They were usually made of polished stone, marble or wood. The great Greek poet Homer describes a particularly beautiful silver bath brought from Egypt. The early Christian church did not preach purity as something related to religion. In ancient times, there were even some Christians who considered an unwashed body as one of the ways to atone for sins. This view began to change in the Middle Ages.

After the Middle Ages passed, most Europeans began to use perfumes and cosmetics instead of bathing. Very few houses had bathtubs. And only in the time of Queen Victoria did the bathroom become a separate place in the house. The tub, made of copper, wood, or iron, was covered with a lid to make it look like a sofa.

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 ... >>

A piece of a neuron for sample processing 30.10.2013

When we look at the hands of a clock or a map of a city, the brain instantly processes visual information, and we can navigate in time and space. New studies by a group of scientists from University College London, Cambridge University (UK) and the University of North Carolina at Chapel Hill (USA) have shown that the simplest calculations can be performed by a short process of a neuron - a dendrite.

A group of scientists from British and American universities examined the neurons of mice, in particular, the part of the brain responsible for processing visual information. Scientists have achieved an important breakthrough: they were able to record incredibly complex electrical and optical recordings directly from a tiny dendrite of a neuron while the brain was processing visual information. These recordings showed that visual stimulation produces specific electrical signals directly in the dendrites, which are tuned to receive visual stimuli.

The new data disproved the widely held belief that this kind of computation is only done by the collaboration of large numbers of neurons, and demonstrates how the core components of a neuron can act as powerful computing centers in their own right.

Professor Michael Hausser noted that dendrites, long thought to be just a "funnel" for an incoming signal, actually play a key role in sorting and interpreting vast amounts of information.

It is assumed that dendritic processing is widespread in many areas of the brain and in many animal species, including humans.
