Can butterflies remember events that happened to them in the caterpillar stage?

For a long time, scientists did not know whether insects with full transformation could retain any memories from past stages. In 2008, scientists at Georgetown University conducted an experiment with hawk moths - they hit the caterpillars with an electric discharge when a certain smell appeared. When the caterpillars became butterflies, they avoided this smell. A temporal distinction was also established - if the caterpillars were trained at the age of up to three weeks, in the butterfly stage they did not shun the smell. The researchers concluded that butterflies retain memory only if the caterpillar's nervous system reaches a certain maturity.

What is anorexia?

This is a psychopathological syndrome, expressed in an obsessive desire to reduce body weight. Those subject to anorexia follow a diet or completely refuse food, resort to other measures, as a result of which the mass decreases so much that pathological changes occur in the body (possibly fatal). This is a real scourge of God for models ... The popularization of thinness by glossy magazines leads to it.

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 ... >>

Electric backpacks for soldiers 03.11.2012

The US Army plans to equip its fighters with backpacks that will generate electricity while moving. The Pentagon has signed a $2,4 million contract with Lightning Packs to develop technology that allows a conventional backpack to use up and down movement to generate electricity. The Suspended Load Backpack can generate up to 7,4W of energy while walking, enough to charge night vision goggles, a powerful LED flashlight, a laptop computer, a GPS navigator and other devices with similar power consumption.

The main difference between the generator backpack and its "brothers" is the presence of a frame, which consists of two parts. A backpack bag is attached to one part, and straps to the other, the frame also has springs and a generator. While walking, the backpack moves up and down relative to the part of the frame to which the straps are attached. This energy is used to generate electricity, in addition, the spring-loaded frame makes it easier to carry the load.

The Suspended Load Backpack is primarily intended for use by the military, but Lightning Packs believes that the generator backpack will become very popular in the commercial market and will be used by any population: from tourists to schoolchildren. At the same time, it will not only ease the load on the back, but will also be able to generate electricity for mobile devices.
